Case Study: Fast Ethernet Without the Fibre Optic

The Problem:
Typically for an industrial park environment, the customer had undertaken occupancy in
three separate business units on the site, physically separated and with a 'multiple
landlord' situation which precluded simple trench-digging to provide network connectivity
using fixed cabling such as optical fibre.
The requirement to run full-speed 100Mbps Fast Ethernet protocols
between R&D, administration and manufacturing facilities precluded the use of BT
leased line 'Megastream' services at 2.048Mbps and microwave links typically limited to
around 34Mbps, with their attendant licensing and signal propagation issues in a built-up
area - a free space optical solution was the only option.
Initially unaware of the advances in free-space technology created by
CableFree Solutions, the reseller had committed to three other competitive infrared
solutions by another distributor, and after installation two serious problems became
apparent - link outage of the 10Mbps system in moderate fog conditions (commonplace for
the region) and complete disconnection of both 100Mbps systems due to minor building
movement.
The Solution:
CableFree Solutions was presented with a challenging task - to replace both 100Mbps
systems in a single day over a weekend, providing connectivity for a mission-critical
service for a customer who understandably had low confidence in free-space technology.
Completed well within schedule, with the only mishap being locating a
faulty connection with the client's cabling, the two CableFree systems have proved highly
reliable in use, solving the issues of fog penetration and beam alignment due to the
superior design and performance specifications offered, despite operating from non-ideal
mounting points inherited from the previous systems.
