… so I can send a recommendation if

I’m watching an interesting program…

… and see when my buddy

accepts the recommendatio

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.

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?
