To increase the voice and data services that wideband is required, at this time the development of mobile WiMAX technology continues to be done to provide data communications services with bandwidth of 75Mbps. The greater the bandwidth provided by the data communication can be done quickly, PDA (SPH-M8200) is one mobile device that uses WiMAX technology to provide fast data access and communications can be done NLOS. PDA (SPH-M8200) is a product of the samsung 4G technology support to provide access to the internet at high speed with low cost compared to 3G.
WiMAX is the Next Generation Technology for communication that is also called with the 4G. I am very interested to use the WiMAX technology because this technology has a large bandwidth and data communication can be performed anywhere without a high antenna. The mobile device where we can send and receive data in the area with a lot of obstruction (NLOS) to be as a city that there is a high building. WiMAX technology that uses Orthogonal Frequency Division Multiplexing (OFDM) modulation to be able to carry more data at high speed is not affected by obstruction.
