Overview
1.1 Description
The EtherLeap
TM
is a Point-to-Point Wireless Bridge that operates on the uncrowded license-free 24 GHz
band. It was specifically created for RF hostile environments where the 2.4 and 5.8 GHZ bands have too
much congestion or interference. It is designed to extend the reach of 10/100Base-T Ethernet networks
through wireless connections where installation barriers and high cost make installing additional copper
connections less desirable. It provides flexibility by being deployable in a large variety of network
architectures. EtherLeap comes pre-configured and is capable to interface seamlessly with Ethernet
networks.
EtherLeap is a Time Division Duplex (TDD) device with an over-the-air data rate of 11 Mbps. It uses
Direct Sequence Spread Spectrum (DSSS) and an adaptive data rate technology to ensure the integrity
of the link under adverse conditions. This allows for smooth changes in the data rate instead of an abrupt
loss of link.
The product can be used in a wide range of applications. It can bridge Hot Spots by providing connectivity
outside the 2.4 GHz and 5.8 GHz bands. It can also bridge Ethernet networks and connect remote
servers to LANs, managing virtually an unlimited number of client MAC addresses on each side of the
link. The unit features 128-bit WEP-Plus encryption.
The EtherLeap comes with an integrated one-foot dish antenna. Because the radio is located at the
antenna, extending the Ethernet cable will not affect the operating range.
Since EtherLeap is based on 802.11 MAC layer, it provides transparent point-to-point connectivity. It
requires only 25 watts to operate and it plugs into any layer-2 switch. These attributes make EtherLeap
ideal for disaster recovery and emergency network restoration applications.
A Windows-based Manager provides configuration and diagnostic utilities that allow you to see vital
information regarding the link between the two units. Information such as signal-to-noise ratio, signal
strength, and noise level all in dB, provides for efficient installation and aiming of the units, as well as
troubleshooting link problems.
The EtherLeap operates with a 48 VDC Adapter. All devices located inside the box get their power from a
DC Power Injector which puts DC power onto the outdoor rated Ethernet cable (Power Over Ethernet, or
POE).
Ethernet cables must be ordered separately .
