A process that verifies the identity of a wireless device or end-user. A common form of
authentication is to verify identities by checking a user name and password to allow network
access.

Collision
Interference resulting from two network devices sending data at the same time. The network
detects the collision of the two transmitted packets and discards both of them.
Coverage
The region within which a paging receiver can reliably receive the transmission of paging signals.
CoverageArea
The geographical area that can be served by a mobile communications network or system.
CoverageHole
An area within the radio coverage footprint of a wireless system where the RF signal level is
below the design threshold. Physical obstructions such as buildings, foliage, hills, tunnels, and
indoor parking garages are usually the cause of coverage holes.

Dynamic
HostConfigurationProtocol(DHCP)
A protocol that assigns temporary IP addresses automatically to client stations logging onto an IP
network, so the IP addresses do not have to be assigned manually. The ENH200 contains an
internal DHCP server that automatically allocates IP address using a user-defined range of IP
addresses.
DeadSpot
An area within the coverage area of a WLAN where there is no coverage or transmission falling
off. Electronic interference or physical barriers such as hills, tunnels, and indoor parking garages
