Define requirements: specify
functionality of device. E.g: I/O and
performance requirements
C coding: Source code of a
program that implements a Finite field
divider.
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.

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

What is Eap,AES, Multicast securuty
Extensible Authentication Protocol
Advanced Encryption Standard
Each SS shall have a 48-bit universal MAC address, as defined in IEEE Std 802®-2001. This address
uniquely defines the SS from within the set of all possible vendors and equipment types. It is used during the
initial ranging process to establish the appropriate connections for an SS. It is also used as part of the
authentication process by which the BS and SS each verify the identity of the other.
