3g broadband
The first pre-commercial 3G network was launched by NTT DoCoMo in Japan branded FOMA, in May 2001 on a pre-release of W-CDMA technology. The first commercial launch of 3G was also by NTT DoCoMo in Japan on October 1, 2001, although it was initially somewhat limited in scope; broader availability was delayed by apparent concerns over reliability. The second network to go commercially live was by SK Telecom in South Korea on the 1xEV-DO technology in January 2002. By May 2002 the second South Korean 3G network was by KT on EV-DO and thus the Koreans were the first to see competition among 3G operators.

The first European pre-commercial network was at the Isle of Man by Manx Telecom, the operator then owned by British Telecom, and the first commercial network in Europe was opened for business by Telenor in December 2001 with no commercial handsets and thus no paying customers. These were both on the W-CDMA technology.

The first commercial United States 3G network was by Monet Mobile Networks, on CDMA2000 1x EV-DO technology, but this network provider later shut down operations. The second 3G network operator in the USA was Verizon Wireless in October 2003 also on CDMA2000 1x EV-DO. AT&T Mobility is also a true 3G network, having completed its upgrade of the 3G network to HSUPA.

The first pre-commercial demonstration network in the southern hemisphere was built in Adelaide, South Australia by m.Net Corporation in February 2002 using UMTS on 2100 MHz. This was a demonstration network for the 2002 IT World Congress. The first commercial 3G network was launched by Hutchison Telecommunications branded as Three in March 2003.

In December 2007, 190 3G networks were operating in 40 countries and 154 HSDPA networks were operating in 71 countries, according to the Global Mobile Suppliers Association (GSA). In Asia, Europe, Canada and the USA, telecommunication companies use W-CDMA technology with the support of around 100 terminal designs to operate 3G mobile networks.

In Europe, mass market commercial 3G services were introduced starting in March 2003 by 3 (Part of Hutchison Whampoa) in the UK and Italy. The European Union Council suggested that the 3G operators should cover 80% of the European national populations by the end of 2005.

Roll-out of 3G networks was delayed in some countries by the enormous costs of additional spectrum licensing fees. (See Telecoms crash.) In many countries, 3G networks do not use the same radio frequencies as 2G, so mobile operators must build entirely new networks and license entirely new frequencies; an exception is the United States where carriers operate 3G service in the same frequencies as other services. The license fees in some European countries were particularly high, bolstered by government auctions of a limited number of licenses and sealed bid auctions, and initial excitement over 3G's potential. Other delays were due to the expenses of upgrading equipment for the new systems.

By June 2007 the 200 millionth 3G subscriber had been connected. Out of 3 billion mobile phone subscriptions worldwide this is only 6.7%. In the countries where 3G was launched first - Japan and South Korea - 3G penetration is over 70%.[11] In Europe the leading country is Italy with a third of its subscribers migrated to 3G. Other leading countries by 3G migration include UK, Austria, Australia and Singapore at the 20% migration level. A confusing statistic is counting CDMA 2000 1x RTT customers as if they were 3G customers. If using this definition, then the total 3G subscriber base would be 475 million at June 2007 and 15.8% of all subscribers worldwide.

In Canada, Rogers Wireless was the first to implement 3G technology, with HSDPA services in eastern Canada in early 2007. Their subsidiary Fido Solutions offers 3G as well. Because they were the only incumbent carrier (out of 3) with UMTS/HSDPA capability, for 2 years Rogers was the sole provider of the popular Apple iPhone. Realizing they would miss out on roaming revenue from the 2010 Winter Olympics, Bell and Telus formed a joint venture and rolled out a shared HSDPA network using Nokia Siemens technology. Bell launched their 3G wireless lineup on 4 November 2009, and Telus followed suit a day later on 5 November 2009. With these launches, the popular iPhone is now available on all 3 incumbent national carriers.

Mobitel Iraq is the first mobile 3G operator in Iraq. It was launched commercially on February 2007.

China announced in May 2008, that the telecoms sector was re-organized and three 3G networks would be allocated so that the largest mobile operator, China Mobile, would retain its GSM customer base. China Unicom would retain its GSM customer base but relinquish its CDMA2000 customer base, and launch 3G on the globally leading WCDMA (UMTS) standard. The CDMA2000 customers of China Unicom would go to China Telecom, which would then launch 3G on the CDMA 1x EV-DO standard. This meant that China would have all three main cellular technology 3G standards in commercial use. Finally in January 2009, Ministry of industry and Information Technology of China has awarded licenses of all three standards，TD-SCDMA to China Mobile, WCDMA to China Unicom and CDMA2000 to China Telecom. The launch of 3G occurred on 1 October 2009, to coincide with the 60th Anniversary of the Founding of the People's Republic of China.

In November 2008, Turkey has auctioned four IMT 2000/UMTS standard 3G licenses with 45, 40, 35 and 25 MHz top frequencies. Turkcell has won the 45 MHz band with its €358 million offer followed by Vodafone and Avea leasing the 40 and 35 MHz frequencies respectively for 20 years. The 25 MHz top frequency license remains to be auctioned.

The first African use of 3G technology was a 3G videocall made in Johannesburg on the Vodacom network in November 2004. The first commercial launch of 3G in Africa was by EMTEL in Mauritius on the W-CDMA standard. In north African Morocco in late March 2006, a 3G service was provided by the new company Wana.

T-Mobile, a major Telecommunication services provider has recently rolled out a list of over 120 U.S. cities which will be provided with 3G Network coverage in the year 2009.

In 2008, India entered into 3G Mobile arena with the launch of 3G enabled Mobile services by Mahanagar Telephone Nigam Limited (MTNL). MTNL is the first Mobile operator in India to launch 3G services.

3G GPRS

International Mobile Telecommunications-2000 (IMT-2000), better known as 3G or 3rd Generation, is a family of standards for mobile telecommunications defined by the International Telecommunication Union,[1] which includes GSM EDGE, UMTS, and CDMA2000 as well as DECT and WiMAX. Services include wide-area wireless voice telephone, video calls, and wireless data, all in a mobile environment. Compared to 2G and 2.5G services, 3G allows simultaneous use of speech and data services and higher data rates (up to 14.0 Mbit/s on the downlink and 5.8 Mbit/s on the uplink with HSPA+). Thus, 3G networks enable network operators to offer users a wider range of more advanced services while achieving greater network capacity through improved spectral efficiency.

The International Telecommunication Union (ITU) defined the third generation (3G) of mobile telephony standards – IMT-2000 – to facilitate growth, increase bandwidth, and support more diverse applications. For example, GSM (the current most popular cellular phone standard) could deliver not only voice, but also circuit-switched data at download rates up to 14.4 kbps. But to support mobile multimedia applications, 3G had to deliver packet-switched data with better spectral efficiency, at far greater bandwidths.

3g data

3g data
High-Speed Downlink Packet Access (HSDPA) is an enhanced 3G (third generation) mobile telephony communications protocol in the High-Speed Packet Access (HSPA) family, also coined 3.5G, 3G+ or turbo 3G, which allows networks based on Universal Mobile Telecommunications System (UMTS) to have higher data transfer speeds and capacity. Current HSDPA deployments support down-link speeds of 1.8, 3.6, 7.2 and 14.0 Mbit/s. Further speed increases are available with HSPA+, which provides speeds of up to 42 Mbit/s downlink and 84 Mbit/s with Release 9 of the 3GPP standards.
The High-Speed Downlink Shared Channel (HS-DSCH) lacks two basic features of other W-CDMA channels—variable spreading factor and fast power control. Instead, it delivers the improved downlink performance using adaptive modulation and coding (AMC), fast packet scheduling at the base station, and fast retransmissions from the base station, known as hybrid automatic repeat-request
The first phase of HSDPA has been specified in the 3rd Generation Partnership Project (3GPP) release 5. Phase one introduces new basic functions and is aimed to achieve peak data rates of 14.0 Mbit/s (see above). Newly introduced are the High Speed Downlink Shared Channels (HS-DSCH), the adaptive modulation QPSK and 16QAM and the High Speed Medium Access protocol (MAC-hs) in base station.

The second phase of HSDPA is specified in the upcoming 3GPP release 7 and has been named HSPA Evolved. It can achieve data rates of up to 42 Mbit/s.[1] It introduces antenna array technologies such as beamforming and Multiple-input multiple-output communications (MIMO). Beam forming focuses the transmitted power of an antenna in a beam towards the user’s direction. MIMO uses multiple antennas at the sending and receiving side. Deployments are scheduled to begin in the second half of 2008.

Further releases of the standard have introduced dual carrier operation, i.e. the simultaneous use of two 5 MHz carrier. By combining this with MIMO transmission, peak data rates of 84 Mbit/s can be reached under ideal signal conditions.

After HSPA Evolved, the roadmap leads to E-UTRA (Previously "HSOPA"), the technology specified in 3GPP Release 8. This project is called the Long Term Evolution initiative. The first release of LTE offers data rates of over 320 Mbit/s for downlink and over 170 Mbit/s for uplink using OFDMA modulation.[1]
[edit] Adoption

As of August 28, 2009, 250 HSDPA networks have commercially launched mobile broadband services in 109 countries. 169 HSDPA networks support 3.6 Mbit/s peak downlink data throughput. A growing number are delivering 21 Mbit/s peak data downlink and one network has been upgraded to 28 Mbit/s. Several others will have this capability by end 2009 and the first network supporting 42 Mbit/s network is set to come online in late 2009.

This protocol is a relatively simple upgrade where UMTS is already deployed.

CDMA-EVDO networks had the early lead on performance, and Japanese providers were highly successful benchmarks for it. But lately this seems to be changing in favour of HSDPA as an increasing number of providers worldwide are adopting it. In Australia, Telstra announced that its CDMA-EVDO network would be replaced with a HSDPA network (since named NextG), offering high speed internet, mobile television and traditional telephony and video calling. Rogers Wireless deployed HSDPA system 850/1900 in Canada on April 1, 2007. In July 2008, Bell Canada and Telus announced a joint plan to expand their current shared EVDO/CDMA network to include HSDPA. Bell Canada launched their joint network November 4, 2009, while Telus launched November 5, 2009

Still, several developing countries have not awarded 3G licenses and customers await 3G services. China delayed its decisions on 3G for many years, mainly because of their Government's delay in establishing well defined standards.[12]

Mobile phone

mobile phone
A mobile phone or mobile (also called cellphone and handphone,[1] as well as cell phone, wireless phone, cellular phone, cell, cellular telephone, mobile telephone or cell telephone) is a long-range, electronic device used for mobile telecommunications (mobile telephony, text messaging or data transmission) over a cellular network of specialized base stations known as cell sites. In addition to the standard voice function, current mobile phones may support many additional services, and accessories, such as SMS for text messaging, email, packet switching for access to the Internet, gaming, Bluetooth, infrared, camera with video recorder and MMS for sending and receiving photos and video, MP3 player, radio and GPS. Most current mobile phones connect to a cellular network consisting of switching points and base stations (cell sites) owned by a mobile network operator (the exception is satellite phones, which are mobile but not cellular).

As opposed to a radio telephone, a mobile phone offers full duplex communication, automatised calling to and paging from a public switched telephone network (PSTN), and handoff (American English)/handover (British/European English) during a phone call when the user moves from one cell (base station coverage area) to another. A mobile phone offers wide area service, and should not be confused with a cordless telephone, which also is a wireless phone, but only offer telephony service within a limited range, e.g. within a home or an office, through a fixed line and a base station owned by the subscriber.

The International Telecommunication Union estimated that mobile cellular subscriptions worldwide would reach approximately 4.1 billion by the end of 2008.[2] Mobile phones have gained increased importance in the sector of Information and communication technologies for development in the 2000s and have effectively started to reach the bottom of the economic pyramid

pda interface

PDAs for business use, including the BlackBerry and Palm Treo, have full keyboards and scroll wheels or thumb wheels to facilitate data entry and navigation, in addition to supporting touch-screen input. There are also full-size foldable keyboards available that plug directly, or use wireless technology to interface with the PDA and allow for normal typing. BlackBerry has additional functionality, such as push-based email and applications.

Newer PDAs, such as the Apple iPhone, iPod Touch and Palm Pre include new user interfaces using other means of input. The iPhone and iPod touch uses a technology called Multi-touch.

PDA search

A personal digital assistant (PDA) is a handheld computer, also known as a palmtop computer. Newer PDAs commonly have color screens and audio capabilities, enabling them to be used as mobile phones (smartphones), web browsers, or portable media players. Many PDAs can access the Internet, intranets or extranets via Wi-Fi, or Wireless Wide Area Networks (WWANs). Many PDAs employ touchscreen technology.

The first PDA is considered to be the Casio PF-15115-36 released in May 1983. GO Corp. was also pioneering in the field. The term was first used on January 7, 1992 by Apple Computer CEO John Sculley at the Consumer Electronics Show in Las Vegas, Nevada, referring to the Apple Newton. In 1996 Nokia introduced the first mobile phone with full PDA functionality, the 9000 Communicator, which has since grown to become the world's best-selling PDA and which spawned a category of phones called the smartphone. The only function it does not have is that it is unable to record videos. Today the vast majority of all PDAs are smartphones, selling over 150 million units while non-phone ("stand-alone") PDAs sell only about 3 million units per year. The RIM BlackBerry, the Apple iPhone and the Nokia N-Series are typical smartphones

PDA price

A newer entrant into the Pocket PC market is Palm which sells devices like the Treo 700w/wx[9] based on Windows Mobile 5.0 and featuring integrated telephony. Previously Palm only produced PDAs running the Palm OS (as did the first versions of the Palm Treo) and still sell versions of the Treo based on the Palm operating system.

HTC, responsible for manufacturing up to 80% of all phone enabled Windows Mobile devices for other companies (including HP and O2) as well as many non-phone enabled Pocket PCs (for companies such as Dell, HP and Fujitsu Siemens), are now marketing Windows Mobile devices under their own brand (such as the HTC Touch), as well as that of Dopod

PDA 2002

One of the more popular high-end consumer-market Pocket PCs was the Dell Axim x51v, which was discontinued in 2007. Hardware specs included 3.7" color TFT VGA display with 640x480 resolution, Intel XScaleTM PXA270 Processor at 624 MHz, 336MB of Memory (256MB Flash, 64MB SDRAM), integrated 802.11b and Bluetooth 1.2, integrated Intel 2700G multimedia accelerator with 16MB video memory. Expansion was possible via CompactFlash Type II and SD slots (supporting SDIO Now!, SDIO and MMC cards). Included is a 1,100 mAh user replaceable battery (est. 4-6.5 hours, 2200mAh also available).

Some Pocket PCs feature integrated GPS often combined with mobile phone functionality. Pocket PCs with built-in telephony differ from Windows Mobile Smartphone Edition devices in several respects, including the lack of a touchscreen on the latter. Some examples of current Pocket PCs with GPS integrated are the Fujitsu Siemens Pocket Loox N560[5], a high-end Pocket PC with a VGA screen and an integrated SiRF Star III GPS; the HTC TyTN[6], a small communicator with integrated slide in keyboard; the HP hw6945 and HP iPAQ hw6515 with integrated thumb-board, GPS and GSM/GPRS telephony; the HTC top of the line Universal, branded as the QTek 9000 (also branded by various telecommunications companies as the Orange SPV M5000, T-mobile MDA Pro, Vodafone VPA IV, O2 Xda Exec, i-Mate JasJar, Dopod 900

Newest pda

Pocket PCs are manufactured and sold by several different companies; the major manufacturers include HP (under the iPAQ and now defunct Jornada brands), Toshiba, Acer, ASUS, Dell (under the now defunct Axim brand), Fujitsu Siemens, HTC, and ViewSonic. In Mid-2003, Gateway Computers and JVC announced they would release Pocket PCs, but the projects were discontinued before a product was released. Prices in 2003 ranged from around $800 USD for the high-end models, some of which are combined with cell phones, to $200 for low-end models. A $100–$200 model was rumored to be released within 2004 or early 2005, although the lowest price for a just-released Pocket PC never went under $300. Many companies ceased to sell PDA's by 2003–2004 because of a declining market. Major Companies such as Viewsonic and Toshiba stopped producing new Pocket PCs.

Before the Pocket PC brand was launched, there were other Windows-based machines of the same form factor made by HP, Philips, and others called Palm-size PCs. These devices ran Windows CE 2.0–2.11 and had an interface that was similar to the then-current desktop versions of Windows, such as Windows 98.

Companies like O2, T-Mobile and Orange are marketing Pocket PCs that have integrated mobile telephony (smartphones). All users have to do is put in the SIM card and follow the wizard, to put their SIM contacts in the address book. An example is O2's Xda, or T-Mobile's MDA Compact. Both of these devices, whilst bearing the phone operator's logo, are actually manufactured by the dominant Pocket PC manufacturer HTC

Pocket pcs

pocket pcs A Pocket PC, abbreviated P/PC or PPC, is a hardware specification for a handheld-sized computer (Personal digital assistant) that runs the Microsoft Windows Mobile operating system. It may have the capability to run an alternative operating system like NetBSD, Linux, Android or others. It has some of the capabilities of modern desktop PCs.

Currently there are thousands of applications for handhelds adhering to the Microsoft Pocket PC specification, many of which are freeware. Some of these devices also include mobile phone features. Microsoft compliant Pocket PCs can also be used with many other add-ons like GPS receivers, barcode readers, RFID readers, and cameras.

In 2007, with the advent of Windows Mobile 6, Microsoft dropped the name Pocket PC in favor of a new naming scheme. Devices without an integrated phone are called Windows Mobile Classic devices instead of Pocket PCs. Devices with an integrated phone and a touch screen are called Windows Mobile Professional devices and devices without a touch screen are called Windows Mobile Standard devices.
The Pocket PC is an evolution from previous calculator-sized computers. Keystroke-programmable calculators which could do simple business and scientific applications were available by the 1970s. In 1982, Hewlett Packard's HP-75 incorporated a 1-line text display, an alphanumeric keyboard, BASIC language and some basic PDA capabilities. The HP 200Lx series packed a PC-compatible DOS computer with graphics display and QWERTY keyboard into a palmtop format. The Omigo 100 used a pen and graphics interface on dDOS, but was not widely liked by the United States. The HP 300XL built a palmtop computer on the Windows CE operating system, but not until the form factor and features of the Palm platform were adapted that it was named the Pocket PC, after the Pocket-Rocket.

Pocket PC 2000 and 2002
Pocket PC 2002 (launched October 2001) and Pocket PC 2000 (launched April 2000) both ran Windows CE 3.0 underneath. Some Pocket PC 2002 devices were also sold as "Phone Editions" which included cell phone functionality in addition to the PDA capabilities.

Handhelds pda

A mobile device (also known as cellphone device, handheld device, handheld computer, "Palmtop" or simply handheld) is a pocket-sized computing device, typically having a display screen with touch input or a miniature keyboard. In the case of the personal digital assistant (PDA) the input and output are combined into a touch-screen interface. Smartphones and PDAs are popular amongst those who require the assistance and convenience of a conventional computer, in environments where carrying one would not be practical. Enterprise digital assistants can further extend the available functionality for the business user by offering integrated data capture devices like Bar Code, RFID and Smart Card readers.

IPHONE

The iPhone is an internet-connected multimedia smartphone designed and marketed by Apple Inc. with a flush multi-touch screen and a minimal hardware interface. The device does not have a physical keyboard, so a virtual keyboard is rendered on the touch screen instead. The iPhone functions as a camera phone (including text messaging and visual voicemail), a portable media player (equivalent to an iPod), and an Internet client (with email, web browsing, and local Wi-फीconnectivity). The first-generation phone hardware was quad-band GSM with EDGE; the second generation also adds UMTS with HSDPA.
Apple announced the iPhone on January 9, 2007.The announcement was preceded by rumors and speculation that circulated for several months.The iPhone was initially introduced in the United States on June 29, 2007, and has since been introduced worldwide. It was named Time magazine's "Invention of the Year" in 2007. On July 11, 2008, the iPhone 3G was released. It supports faster 3G data speeds and Assisted GPS। On March 17, 2009, Apple announced the iPhone firmware version 3.0, due to be released in mid 2009.
Development of iPhone began with Apple CEO Steve Jobs' direction that Apple engineers investigate touchscreens. Apple created the device during a secretive and unprecedented collaboration with AT&T Mobility—Cingular Wireless at the time—at an estimated development cost of US$150 million over thirty months. Apple rejected the "design by committee" approach that had yielded the Motorola ROKR E1, a largely unsuccessful collaboration with Motorola. Instead, Cingular gave Apple the liberty to develop the iPhone's hardware and software in-house. Numerous codenames and even fake prototypes were devised to keep the project secretJobs unveiled iPhone to the public on January 9, 2007 in a keynote address. Apple was required to file for operating permits with the FCC, but such filings are available to the public, so the announcement came several months before the iPhone received approval. The iPhone went on sale in the United States on June 29, 2007. Apple closed its stores at 2:00 pm local time to prepare for the 6:00 pm iPhone launch, while hundreds of customers lined up at stores nationwide. On launch weekend, Apple sold 270,000 iPhones in the first thirty hours. The original iPhone was made available in the UK, France, and Germany in November 2007, and Ireland and Austria in the spring of 2008.
On July 11, 2008, Apple released the iPhone 3G in twenty-two countries, including the original six. Apple sold 1 million iPhone 3Gs in its first 3 days on sale, enough to overload Apple's United States iTunes servers. Apple has since released the iPhone 3G in upwards of eighty countries and territories.
Over 3 million units were sold in the first month after the 3G launch, at a "blistering sales pace". The phenomenon of popular willingness to upgrade to the 3G so soon after purchase of an earlier model was attributed to Apple's popularity and its frequent imitators. The anomalously high demand for the first-generation iPhone was reflected in free-market prices for older models that began to rise steadily within days of the 3G launch resetting the price baselines.
On January 21, 2009, Apple announced sales of 4.36 million iPhone 3Gs in the first quarter of fiscal 2009, ending December 2008, totaling 17.4 million iPhones to date. Sales from Q4 2008 surpassed RIM's BlackBerry sales of 5.2 million units, making Apple the third largest mobile phone manufacturer by revenue, after Nokia and Samsung. While iPhone sales constitute a significant portion of Apple's revenue, some of this income is देफेर्रेड
The iPhone allows audio conferencing, call holding, call merging, caller ID, and integration with other cellular network features and iPhone functions. For example, if a song is playing while a call is received, it gradually fades out, and fades back when the call has ended. The proximity sensor shuts off the screen and touch-sensitive circuitry when the iPhone is brought close to the face, both to save battery and prevent unintentional touches. The iPhone only supports voice दिअलिंग through third party applications[citation needed] and video calling is not supported at all.
The iPhone includes a visual voicemail (in some countries) feature allowing users to view a list of current voicemail messages on-screen without having to call into their voicemail. Unlike most other systems, messages can be listened to and deleted in a non-chronological order by choosing any message from an on-screen list. AT&T, O2, T-Mobile Germany, and Orange modified their voicemail infrastructure to accommodate this new feature designed by Apple.[citation needed]
A music ringtone feature was introduced in the United States on September 5, 2007. Users can create custom ringtones from songs purchased from the iTunes Store for a small additional fee. The ringtones can be 3 to 30 seconds long from any part of a song, can fade in and out, pause from half a second to five seconds when looped, or loop continuously. All customizing can be done in iTunes, and the synced ringtones can also be used for alarms. Custom ringtones can also be created using Apple's GarageBand software 4.1.1 or later (available only on Mac OS X) and third-party tools.Custom ringtones are not supported in some countries।
The layout of the music library is similar to that of an iPod or current Symbian S60 phones. The iPhone can sort its media library by songs, artists, albums, videos, playlists, genres, composers, podcasts, audiobooks, and compilations. Options are always presented alphabetically, except in playlists, which retain their order from iTunes. The iPhone uses a large font that allows users plenty of room to touch their selection. Users can rotate their device horizontally to landscape mode to access Cover Flow. Like on iTunes, this feature shows the different album covers in a scroll-through photo library. Scrolling is achieved by swiping a finger across the screen.
The iPhone supports gapless playback. Like the fifth generation iPods introduced in 2005, the iPhone can play digital video, allowing users to watch TV shows and movies in widescreen. Unlike other image-related content, video on the iPhone plays only in the landscape orientation, when the phone is turned sideways. Double-tapping switches between widescreen and fullscreen video playback.
The iPhone allows users to purchase and download songs from the iTunes Store directly to their iPhone. The feature originally required a Wi-Fi network, but now can use the cellular data network if one is not available.
External TV tuner cards are available for watching mobile TV, via TV stations on 1seg in Japan (SoftBank), and for soon for the proprietary subscription-based FLO TV in the U.S. (Qualcomm).[citation needed] There is also a "converter" for watching DVB-H in Europe and elsewhere via WiFi streaming video (PacketVideo)।
Internet access is available when the iPhone is connected to a local area Wi-Fi or a wide area GSM or EDGE network, both second-generation (2G) wireless data standards. The iPhone 3G also supports third-generation UMTS and HSDPA 3.6, but not HSDPA 7.2 or HSUPA networks. AT&T introduced 3G in July 2004, but as late as 2007 Steve Jobs felt that it was still not widespread enough in the US, and the chipsets not energy efficient enough, to be included in the iPhone. The iPhone 3G has a maximum download rate of 1.4 Mbp/s in the US, although faster speeds are available in Europe (T-Mobile in The Netherlands, for instance, provides 2048 kbyte/s down/384kbit/s up). Support for 802.1X, an authentication system commonly used by university and corporate Wi-Fi networks, was added in the 2.0 version update.
By default, the iPhone will ask to join newly discovered Wi-Fi networks and prompt for the password when required. Alternatively, it can join closed Wi-Fi networks manually. The iPhone will automatically choose the strongest network, connecting to Wi-Fi instead of EDGE when it is available. Similarly, the iPhone 3G prefers 3G to 2G, and Wi-Fi to either. Users can disable all wireless connections by activating Airplane Mode.
Safari is the iPhone's native web browser, and it displays pages similar to its Mac OS X counterpart. Web pages may be viewed in portrait or landscape mode and supports automatic zooming by pinching together or spreading apart fingertips on the screen, or by double-tapping text or images. The iPhone supports neither Flash nor Java. Consequently, the UK's Advertising Standards Authority adjudicated that an advertisement claiming the iPhone could access "all parts of the internet" should be withdrawn in its current form, on grounds of false advertising. The iPhone supports SVG, CSS, HTML Canvas, and Bonjour.
The maps application can access Google Maps in map, satellite, or hybrid form. It can also generate directions between two locations, while providing optional real-time traffic information. Support for walking directions, public transit, and street view was added in the version 2.2 software update. During the iPhone's announcement, Jobs demonstrated this feature by searching for nearby Starbucks locations and then placing a prank call to one with a single tap. Apple also developed a separate application to view YouTube videos on the iPhone, which streams videos after encoding them using the open H.264 codec. Simple weather and stock quotes also tap in to the Internet.
iPhone users can and do access the internet frequently, and in a variety of places. According to Google, the iPhone generates 50 times more search requests than any other mobile handset. According to Deutsche Telekom CEO René Obermann, "The average Internet usage for an iPhone customer is more than 100 megabytes. This is 30 times the use for our average contract-based consumer customers
