Wireless Multiplexer

RAD's Airmux-200 wireless multiplexer is a carrier-class, high capacity cost effective point-to-point and multi point-to-point transmission system used to connect Ethernet and E1/T1 circuits between two distant sites over broadband wireless.

The Airmux-200 wireless multiplexer combines legacy TDM and Ethernet services for transmission over 2.3 GHz, 2.4 GHz, 4.9 GHz, and 5.x GHz, as well as licensed 2.5 GHz BRS bands. The Airmux-200 wireless multiplexer has a net payload throughput of up to 18 Mbps, with a maximum transmission distance of up to 80 kilometers (50 miles). Transmission is encrypted to ensure security.

Typical applications include service extension to remote/rural locations, cellular backhaul, emergency services and temporary deployment, wireless backup, voice traffic extension over wireless, and lossless hot spot backhauling.

• Combines voice and data over a single link, cutting access costs

• License exempt transmission enables fast and affordable deployment

• Installation and alignment tools enable easy deployment

• Save the costs of leased lines while extending services

• Ideal solution for cellular backhaul applications and remote coverage areas

Airmux-200 is a carrier-class, high capacity, affordable wireless multiplexer, connecting E1 or T1 and Ethernet networks point-to-point and multi 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 bands, in addition to 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 rapid deployment of E1 and T1 lines 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.

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.

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 co-location (multipoint-to-point) mode.
