Broadband Wireless Multiplexer

RAD's Airmux-200 broadband wireless multiplexer is a carrier-class, point-to-point and multi point-to-point transmission system for connecting Ethernet and E1/T1 circuits between two distant sites over broadband wireless.

 

The Airmux-200 broadband wireless multiplexer combines legacy TDM and Ethernet services for transmission over unlicensed, sub-6GHz bands, as well as over licensed 2.5 GHz BRS bands. The Airmux-200 broadband 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, video surveillance, wireless backup, 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 and quick time to market of new services

• Save the costs of leased lines while extending services

• Cost-optimized for video surveillance with asymmetric Ethernet bandwidth support

• High reliability and availability based on robust air interface protocol and 1+1 link redundancy

Airmux-200 is a carrier-class, high capacity, affordable wireless multiplexer, connecting E1 or T1 and Ethernet networks in a multiple point-to-point topology 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, 4.8 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.

 

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.

The Airmux-200 offers an ideal solution for video surveillance and security applications, such as perimeter security, license plate monitoring and face recognition. Supporting asymmetric Ethernet throughput of 2/5 Mbps over a distance of up to 20 km, it provides cost-effective support to meet requirements for advanced IP camera communications, including high-capacity megapixel transmissions, real-time alerts, minimal quality degradation and high service availability.

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-EMS 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.

 

Configurations: Airmux-200 also functions in a Power over Ethernet mode for Ethernet services and in a colocation (multipoint-to-point) mode.
