Define requirements: specify functionality of device. E.g: I/O and performance requirements
Verilog coding entry: functional description of architectures. Include combinational logic design and RTL (Register Transfer Level) coding.
Synthesis: generates a netlist from the Verilog code. Netlist is a low level abstraction of the code.
Place and Route: determines the placement of each cell and connections between cells in the chip.
Configuration: a process in which the circuit design (bitstream file) is downloaded into the FPGA.
C coding: Source code of a program that implements a Finite field divider.

CS maps data (ATM cells or IP packets) to a certain unidirectional connection identified by the Connection Identifier (CID) and associated with a certain QoS.
CS adapts higher layer protocols to MAC CPS.
May also offer payload header suppression.

Additional Factors to consider
Sec
uri
ty
Security of wireless media has always been questionable. WiMax has been proved to suffer from weak security.
Cov
erag
e
Success of any solution will depend on support Non Line of sight operation.
Pow
er
Since BWA products transmit at higher power, they represent a drain on the battery.
Per
form
ance
Multimedia has stringent expectations from the underlying network.High bandwidth alone cannot satisfy all multimedia requirements.

42
Disadvantages of WiMAX
Line-of-sight (LOS) is required for long distance (5-30 mile) connections
Certain conditions —terrain, weather and large buildings—can act to reduce the maximum range
Other wireless electronics can interfere with the WiMAX connection & cause a reduction in data throughput
licensed airwave frequencies are limited availability. Unlicensed airwaves are free but all can use them—difficult to control service quality as other users of the same band could cause interference
“ WIMAX ” What are the risks?
