The Scenario:

Internet service provides frequently have to connect separate buildings on industrial estates, science parks and university campus environments which may be separated by roads or other obstacles, where provision of communications links is a frequent problem.

Traditional connectivity solutions for links between buildings include leased-line, fibre-optic, copper cable or microwave links – but all of these have associated penalties.

Cablefree systems use optical technology to offer a number of advantages:

Data rates up to 622Mbps
No site or frequency licenses unlike radio or microwave systems
No disruption from trench digging - roads, rivers or railways are no obstacle
No risk of interference, signal reflections or airport radar systems
No leased-line rental or connection charges
No limitation on bandwidth – up to 1500Mbps with current technology
Quick to install
On-site upgrades ensure ‘future-proof’ network provision
Permanent or temporary use, medium-term leasing options also available
Cost-effective solution

Microsoft Exhibition, Nice (France) - July 1998

Cablefree Solutions was approached to supply a communications link to provide a 10Mbps Internet connectivity link at the prestigious Microsoft exhibition at Nice, France.

The requirement to connect 10Mbps between buildings could not be met by Spread Spectrum wireless, with a 2Mbps aggregate bandwidth. Conversely, a Telecoms leased-line was non-viable owing to the lead-time, high cost and short duration of the show. A microwave link would have been problematic with reflections from the tall, metallic-clad reflective buildings concerned.

Cablefree was the ideal choice - a system configured with a 10Base-T interface for communication at 10Mbps allowed connection of up to 2,000 computer terminals simultaneously, with a simple installation spanning 650m of free space between the main two buildings housing the exhibition.

The high reliability and uniquely flexible nature of Cablefree gave the client dependable communications despite harsh operating conditions and non-ideal installation positions - whilst solving the short-term need well under budget and ahead of expected timescales, and without licensing issues or excessive rental charges to pay.
