:-"The frequencies higher than 10 GHz are practical only for fixed line-of-sight (LOS) type services. Non-line of sight (NLOS) communications perform better when the frequencies of operation are kept under 10 GHz. The frequencies below 6 GHz have better propagation properties and are better suited for mobile communications because they most likely guarantee service to all the niches of the coverage area."

:-"To approach the theoretical capacity of the system, WiMAX uses a combination of adaptive modulation schemes and coding ranging from ½ rate QPSK to 5/6 rate 64QAM. The amount of error correction applied to each transmission is adjustable and can be changed depending on the required QoS and based on the reliability of the link between each user and the base station."

:-"The extensive flexibility introduced into the WiMAX standard also makes it harder to model correctly."

:-"Time Division Duplex (TDD) transmission scheme of the 802.16e standard will be considered. In the initial working group release, the standard supports 5 and 10 MHz bandwidth allocations for each radio frequency channel. The available channel bandwidth is made up of sub-carriers each of which can be modulated individually with information. WiMAX uses Orthogonal Frequency Division Multiple Access (OFDMA) to assign sub-carriers to different users. The number of sub-carriers available for assignment in the UL and DL are a function of the channel bandwidth, the frame size, and the UL/DL transmit ratio. In mobile WiMAX, the smallest unit of frequency-time allocation available is a slot which contains 48 data sub-carriers."

:-"The sub-carriers comprising a slot can be made up of adjacent sub-carriers or can be allocated in a distributed fashion throughout the available carrier space. In general, distributed carrier allocations perform better in mobile environments, while adjacent sub carriers are better suited for fixed links. The number of slots assigned to a particular user per frame is a function of their data needs."
