UK wireless connectivity manufacturer adds new millimetre-wave products for 4G and 3G solutions to its range of CableFree products

Wireless Excellence adds 4G LTE backhaul to its portfolio of wireless links

Wireless Excellence is launching a new set of solutions for LTE/4G and 3G backhaul. The new products combine millimeter-wave (MMW) using E-band and 60GHz technologies, with FSO (free space optics) to provide high capacity Gigabit backhaul networks to power cellular networks.

The new CableFree MMW links offer full-speed Gigabit capacities and advanced, user-friendly features such as 1Gbps full duplex capacity with forward error correction (FEC), power-over-Ethernet and fibre optic interface options, and can be fed by either AC or DC power as site conditions permit.  

With ultra-low power consumption, the MMW links can be powered off existing sources such as street lighting fixtures, and for remote areas, alternative power sources such as solar with batteries.  

Using integrated advanced high gain antennas, the MMW links utilise narrow ‘pencil beam’ transmissions, which minimise potential sources of interference and maximise spatial re-use for the dense network deployments needed in busy cities. 

The 60GHz frequencies, which are ideal for sub-kilometre applications, are used for short links. To implement longer links, E-band (70-80GHz) frequencies are used up to 8km (depending on rain zone region).  

For ultra high availability, dual-technology links combining MMW and FSO are used, which provide 2Gbps of capacity, falling back to 1Gbps when either path is disrupted. As FSO and MMW have complementary fade patterns in fog and rain, high availability exceeding 99.999%, as well as high throughput of 1Gbps minimum are ensured in all conditions, as well as adding path protection and equipment resilience.

The company said that the new set of backhaul products is available immediately for volume shipment, for live deployments as well as trials, with full references available. Stringent environmental, safety and regulatory requirements are met for homologation in all key global markets. A full range of support and training services are available.

Wireless Excellence is the designer and manufacturer of the CableFree range of products for high performance wireless connectivity. CableFree products include Free Space Optics (FSO), OFDM Radio, Licensed Microwave, Millimeter-Wave, WiMAX and WiFi, with customer installations in over 60 countries worldwide. 

he products will be on show at Mobile World Congress in Barcelona (25-28 February 2013).
