Airmux-200

Broadband Wireless Multiplexer

Airmux-200 is a carrier-class, high capacity,

affordable multiplexer, connecting E1/T1 and

Ethernet networks point-to-point over a

wireless link. Compliant with FCC, CAN/CSA and

ETSI regulations for license-exempt transmission,

the Airmux-200 operates over 2.3 GHz,

2.4 GHz, 4.9 GHz, and 5.x GHz, as well as

licensed 2.5 GHz BRS bands. Wireless

transmission saves enterprises the cost of

leased lines while eliminating the service

provider’s need for deploying fiber. The

Airmux-200 thereby enables the rapid

deployment of E1/T1 and Ethernet links at a

fraction of the cost of laying down new cabling.

Airmux-200 consists of an indoor and an

outdoor unit connected by a Cat-5e outdoor

Ethernet cable, allowing a maximum distance of

100 meters (328 feet) between the two units.

The outdoor unit can be ordered with an

integrated antenna or with a connector for an

external antenna.

Cost-effective voice and data transport

Airmux-200 integrates up to four unframed E1

or T1 ports and up to two Ethernet ports for a

net payload throughput of up to 18 Mbps full

duplex. The maximum range of the Airmux-200

is 80 km (50 miles). Throughput is a function of

distance and regulation.

An integrated 10/100BaseT Ethernet bridge

transparently forwards frames and learns up to

2,000 MAC addresses. The accurate E1/T1 clock

recovery, low round-trip delay and high link

availability position the Airmux-200 as a carrier-

class wireless transmission system.

Advanced encryption and security features

Airmux-200 incorporates safeguards to secure

the wireless transmission against possible

attack. The advanced encryption standard (AES)

and dynamic encryption key change are aimed

to prevent unauthorized eavesdropping. These

mechanisms, together with a coded time stamp

(CCM), prevent false transmission from an

intruding terminal. The network management

system and the equipment are protected by a

password and a challenge/response scheme.

An Airmux-200 link can be managed by a

Windows-based application supplied with the

device. The RADview SNMP fault management

application can be ordered in cases where

multiple links are to be deployed and managed

from a central platform. All parameter

configurations are link-based, simplifying

maintenance and installation.

Airmux-200 is an ideal solution for connecting

remote enterprise locations, cellular backhaul,

broadband Last Mile services, and hotspot

backhauling.

Configurations: Airmux-200 also functions in a

Power over Ethernet mode for Ethernet services

and in a colocation (multipoint-to-point) mode.
