xxii Aironet Wireless Client

n Physical Environments. Clear or open areas provide better radio

range than closed or ﬁlled areas. Also, the less cluttered the work

environment, the greater the range.

n Obstructions. A physical obstruction such as shelving or a pillar

can hinder the performance of the Aironet Wireless Client. Avoid

locating the computing device and antenna in a location where there

is a barrier between the sending and receiving antennas.

n Building Materials. Radio penetration is greatly inﬂuenced by the

building material used in construction. For example, drywall con-

struction allows greater range than concrete blocks.

Radio Antenna

The Aironet Wireless Client comes equipped with a detachable 2 dBi

dipole antenna. The antenna provides omni-directional (360°) coverage.

Security Features

The Aironet Wireless Client employs Frequency Hopping Spread Spec-

trum Technology, previously developed for military “anti-jamming” and

“low probability of intercept” radio systems.

The Aironet Wireless Client must be set to the same System Identiﬁer

(SSID) as all other Aironet devices on the wireless infrastructure. Units

with a different SSID will not be able to directly communicate with each

other.
