2.4 GHz band frequency hopping spread spectrum technology
Overview
The RangeLAN2 7100 ISA wireless LAN adapter is a long range, high performance
wireless LAN adapter for AT-bus computers and servers. The 7100’s data rate of
1.6 Mbps exceeds the data rate requirements of most standard PC applications,
making it an ideal wireless platform for high-speed LAN environments. The
RangeLAN2 family also delivers the longest range of any wireless product in its
class—operating at a distance of up to 500 feet in typical office environments
and up to 1000 feet in open space environments. In addition, the RangeLAN2
family provides transparent access to standard wired LAN environments.
The RangeLAN2 7100 provides an easy-to-install wireless extension to existing wired client/server LANs for desktop locations that are difficult or expensive to wire. It can also be used as a standalone peer-to-peer networking solution in smaller companies or departments.
RangeLAN2 Architecture
The RangeLAN2 family sets a new standard for spread spectrum radio design
excellence. RangeLAN2 is based on frequency hopping spread spectrum technology
in the 2.4 GHz band. RangeLAN2’s multi-channel approach enables 15 independent
wireless LANs to operate within the same physical space, effectively increasing
the aggregate capacity of RangeLAN2 networks by 15 times.
Applications
- Hard-to-wire office locations
- Temporary moves
