a donut-like radiation pattern. Since the Dipole radiates in this
pattern, a fraction of radiation is vertical and bleeds across floors
in a multi-story building and have typical ranges up to 100 feet at
11Mbps.
Directional Antennas:
Directional antennas are designed to be used as a bridge antenna
between two networks or for point-to-point communications. Yagi and
Parabolic antennas are used for these purposes as well as others.
Directional antennas can reduce unwanted spill-over as they concentrate
radiation in one direction.

INFRASTRUCTURE NETWORK
Infrastructure network, consists of a fixed infrastructure.
The network is made up of fixed access points that are used to communicate by nodes.
The fixed access points can be connected to other wired or wireless networks to extend the network coverage.
Each access point can cater to more than one node at a time.
However as the number of devices increases, the transmission rate decreases and there is need for more number of access points.
SECURITY CONCERNS

All network technologies have to security features to prevent eavesdropping, unauthorised ..................[:=> Show Contents <=:]

by the Wired Equivalency Policy (WEP) at the MAC layer for
authentication and encryption The original goals of IEEE in defining
WEP was to provide the equivalent security of an unencrypted wired
network. The difference is the wired networks are somewhat protected by
physical buildings they are housed in. On the wireless side, the same
physical layer is open in the airwaves.
WEP provides authentication to the network and encryption of
transmitted data across the network. WEP can be set either to either an
open network or utilizing a shared key system. T..................[:=> Show Contents <=:]

THREATS TO WLAN ENVIRONMENTS

All wireless computer systems face security threats that can compromise its systems and services. Unlike the wired network, the intruder does not need physical access in order to pose the following security threats:

Eavesdropping

This involves attacks against the confidentiality of the data that is being transmitted across the network. In the wireless network, eavesdropping is the most significant threat because the attacker can intercept the transmission over the air from a distance away from the premise of the company.

Tampering
