Welcome to the Aironet 3500 Series Wireless LAN Adapter

1-4

Radio Characteristics

The Wireless LAN Adapter operates in the 2.4 GHz license-
free Industrial Scientific and Medical (ISM) band. Data is
transmitted over a half-duplex radio channel operating up to
2 Megabits per second (Mbps).

Frequency Hopping Radio Technology

The Aironet 3500 Series Wireless LAN Adapter uses
Frequency Hopping Spread Spectrum (FHSS) transmission
previously developed for military “anti-jamming” and “low
probability of intercept” radio systems. The signal is
transmitted over a wide frequency range, using multiple
frequencies. This protects the data transmission from inter-
ference.

Data Transparency and Protocols

The Aironet 3500 Series Wireless LAN Adapter transports
data packets transparently as they move through the
wireless infrastructure. The Wireless LAN Adapter operates
similarly to a standard network product except the wire is
replaced with a radio connection. No special wireless net-
working functions are required. All existing applications,
which operate over a network, will operate using the Aironet
3500 Series Wireless LAN Adapter.
