Samsung P9000 is not a cellphone, but it can show what all one can do when WiMAX hits the mainstream in handsets. The P9000 is a mini PC with an interesting triple-fold design. it has Windows XP Home Edition as operating system, it also has a 5″ 65k color 800×480 pixel resolution display, and a 30GB hard drive. A 1.3 megapixel camera is also featured, as is Bluetooth and a mini-USB port.

The Samsung P9000 also includes CDMA2000 1xEV-DO wireless connectivity over the 1900MHz frequency band to complement the high-speed data WiMAX provides with voice communication capabilities for users. An I/O Pack is also available that adds ports like the VGA monitor connector shown in the photos on the following page.

WiMAX is the name of the certification label that covers the IEEE 802.16 standard. The Mobile WiMAX standard, known as 802.16e, improves upon the original standard that was designed for fixed applications by implementing Scalable OFDMA (Orthogonal Frequency Division Multiple Access). This allows Mobile WiMAX far greater efficiency in mobile and non-line of sight applications. Mobile WiMAX is currently being investigated as the evolution of current 3G data standards for the handsets of tomorrow - Sprint Nextel has shown the most interest in the US market, announcing that it will be spending approximately US$3 billion over the next few years in an effort to establish a WiMAX network. Wimax is truely the future of Wifi.

Mobile WiMAX is attractive to providers as a 4G data network standard because of its increased bandwidth over current 3G networks. Mobile WiMAX offers a theoretical peak downlink speed of 70Mbps, with 10Mbps being a more attainable figure in real world conditions. Compared with the peak downlink speed of UMTS (one of the current 3G data standards) of 3.6Mbps, you can see the obvious difference.

Mobile WiMAX is a completely different technology than current mobile broadband networks, so there is an increased expenditure needed to establish networks…and this will take some time..
