hi there,
i had used for Little time Nokia N810 .now my friend have send me mail about Nokia N810 WiMAX . can any one tell me why wiMAx has such importance to used in it mobile?
thank you !

Mobile WiMAX
Mobile WiMAX or 802.16e standard was ratified by the IEEE in late 2005 as a potential to emerge as a real viable competitor to existing 3G technologies. This potential gained traction when South Korea elected to take a mobile WiMAX compatible standard called wireless broadband (WiBro - since renamed to Mobile WiMAX) to market. This standard however, was based on a different formulation of OFDM than that chosen for the first product profile of 802.16
WiBro/Mobile WiMAX uses an OFDMA™ technology called 1K-FFT. Service for the WiBro/Mobile WiMAX standard is in the 2.3 GHz spectrum range at least in Korea. The technology can be easily adapted to other licensed spectrum. At this point it is anticipated that the WiBro/Mobile WiMAXWiBro/Mobile WiMAX will not be used for unlicensed bands.
Installed in a mobile radio that includes a broadband modem, the SoC enables high-speed broadband handsets to connect to both fixed WiMAX networks, and mobile ones like those enabled by Nokia's new model.
carriers tend to cast WiMAX as a kind of high-speed data carrier that can be paired with existing cellular service, it’s easy to mask over the fact that a single WiMAX connection could conceivably take over the whole mobile circuit. Intel says its 2250 SoC is capable of handling a discrete WiMAX channel of up to 10 MHz bandwidth. Couple that figure with the WiMAX Forum’s recent independent estimate of spectral efficiency at 1.9 bps per hertz, and you have a system with a theoretical maximum throughput approaching 19 Mbps (WiMAX Forum admits the perceived maximum throughput today is more like 14 Mbps).
Nokia Nokia N810 WiMAX
Nokia announced a WiMAX version of its Linux-based Nokia N810 Internet Tablet. Aside from the new WiMAX radio, the WiMAX Edition appears to offer identical hardware to the original N810, but offers a pre-installed version of Nokia's new Linux-based "Tablet OS2008" operating system (OS).
The WiMax Edition is optimized to support Sprint's "Xohm" WiMAX service, which is launching in Chicago, Baltimore, and Washington DC this Spring, with more cities to follow later. Several other devices have recently been announced for use with the service, including the Everex "CloudBook Max" unveiled yesterday, which will use a mobile WiMAX radio chip supplied by GCT Semiconductor, and several Xohm-enabled devices from Linux MID-maker Electrobit (EB).
WiMAX offers a radius of up to 2-3 miles, says Nokia, in comparison with a few hundred feet for WiFi. The wireless technology is also said to offer much greater download speeds of up to 2-4 Mbps per user, with peak download speeds of up to 10Mbps. Also, unlike WiFi, WiMAX was designed from scratch to deliver seamless handoffs from one base station to another, Nokia said.
The Nokia N810 Internet Tablet WiMAX Edition uses Intel "Baxter Peak" WiMAX chips, which use the same silicon as Intel's "Echo Peak" MiniCard module for laptops and ultra-mobile devices, but optimized for small form factors and low power consumption.
Like the N810, the N810 WiMAX Edition is based on a Texas Instruments OMAP 2420, clocked at 400MHz, with 128MB DDR RAM, 256MB flash, and 2GB of internal flash memory, supporting flash cards of up to 8GB. The 5.04 x 2.83 x 0.55-inch tablet is equipped with a slide-out QWERTY keyboard, a 4.13-inch LCD with 800x480 resolution, a USB 2.0 port, a webcam, and GPS. When not in range of a WiMAX network, Nokia notes, the Nokia N810 WiMAX Edition can still access the Internet over WiFi, or via a Bluetooth connection to a cellphone.
Although the WiMAX Edition is nearly identical to the N810, it appears to extend the capability of numerous existing functions such as the GPS receiver and the webcam. Applications that Nokia suggests should flourish in a broadband WiMAX environment include its Voice over Internet Protocol (VoIP) and Instant Messaging (IM) clients, such as Skype, Google Talk, and Gizmo5. According to Nokia, its player for the Rhapsody online music service will "transform the Nokia N810 WiMAX Edition into a portable jukebox with millions of songs available." The GPS capability will be enhanced, it says, with WiMAX access to real-time on-screen maps.
The WiMAX Edition tablet will come standard with a new Tablet OS2008 that is also expected to become available for free download to existing N810 and N800 tablet owners in the second quarter. In addition to software support for WiMAX and Xohm, the update is said to offer an enhanced e-mail client, support for Chinese character rendering in browser and RSS feeds, and automatic periodic software updates, says Nokia.
