Cablefree solves ‘Last-Mile’ network problems

The Scenario:

Telecommunication operators have made huge investment in fixed infrastructure, providing coverage of urban and industrial areas with voice, data and video services connected usually from a backbone SDH fibre network using copper, fibre or wireless technologies.

Cable digging, increasingly unpopular in cities, is regulated by the local authority who may restrict re-digging frequency of roads - and the cost may be prohibitive in any case, especially if a river or railway is in the way.

Using copper telephone lines only provides 2Mbps access per pair - too slow for power users requesting Ethernet at 10/100Mbps or ATM services at 155 or 622Mbps. Cable Modems and xDSL are often not reliable on all installations, depending on the age and condition of the copper cables.

Point-to-point Microwave or radio solutions for 'wireless local loop' may require licensing and often suffer from interference, multipath and signal reflections - and public health fears in urban areas are voiced with increasing frequency.

Cablefree offers an innovative solution offering full-bandwidth ‘Last-Mile’ connectivity:

Data rates up to 622Mbps
Line-of-sight connections in excess of 1,000m
No site or frequency licenses required
No leased-line rental or connection charges
Trench digging and long runs of fibre-optic or copper cable are not needed
Rapid deployment – installation typically within 3 hours
No risk of interference, signal reflections or airport radar systems
No ignition hazard in flammable environments
Suited for permanent or temporary use
Plug-in modules allow on-site upgradeability of data bandwidth or format
Cost-effective, safe and reliable solution

‘Last-Mile’ solutions from CableFree

Cable Network companies can face digging costs, delays, planning restrictions, physical barriers such as rivers and railways and limited technology such as ISDN, ADSL and cable modems to reach customers beyond the network infrastructure – all factors which make infrared technology can be a preferred solution

Cablefree offers state-of-the-art communications systems ready for today’s networking challenges, with industry-standard data interfaces from 2Mbps to 155Mbps and higher. Installations are quick and costs competitive with limited-bandwidth radio and microwave solutions. With no need for frequency allocation or licensing, Cablefree can be deployed to expand networks rapidly anywhere in the world.
