The AirMux-104 is a point-to-point multiplexer
aggregating fractional E1 and Ethernet traffic over a 2.6 Mbps
full duplex wireless link, extending data/voice
transmission up to 40 km (28 miles). The AirMux-104 can
transmit a full E1/T1 (2 Mbps) of Ethernet traffic or a
combination of fractional E1/T1 and Ethernet using direct
sequence spread spectrum (W-CDMA), which also enhances
security.
The unique capabilities of the AirMux-104 in transporting both
Ethernet/IP and TDM traffic over a wireless link make it ideal
for a variety of applications, including:
- connection of LANs and PBXs at dispersed campus locations
- wireless backhauling of cellular base stations
- Wireless Local Loop (WLL)
The AirMux-104 operates at 5.725–5.825 GHz. In many
countries, 5.x GHz is an unlicensed frequency, allowing faster
and more affordable deployment, since no frequency
coordination and license fees are required. Intervals of 5 GHz
bands enable a high quality of service, since they are not
affected by harsh weather conditions such as fog and heavy
rain, nor do they suffer from frequency congestion like the
legacy 2.4 GHz bands.
Powerful forward error correction (FEC) ensures high
reliability over this license-exempt frequency. Time Division
Duplex (TDD) technology is employed, allowing for
bi-directional traffic flow on a single channel, eliminating
the requirement to allocate pairs of channels for the uplink
and the downlink, simplifying the installation procedure.
Enhanced tools for providing a high quality of service are
provided via monitoring tools for Ethernet and radio links. In
addition, local and remote loopbacks are supported on the TDM
link for fault isolation according to the V.54 standard.
