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.

Unlicensed airwaves are free but all can use them— difficult to control service quality as other users of the same band could cause interference 13 NOVEMBER 2009

Editor's Notes
- #40 What is Eap,AES, Multicast securuty Extensible Authentication Protocol Advanced Encryption Standard
- #42 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.
