he wireless bridging solutions are producing cost savings for the client by removing the need to lay cable as well as cutting the risk of damage to water supplies, mains power and other utility trunking. Client revenue is protected since, the installer says, there is minimal disruption to the core activity of the ﬁlling stations which can remain open throughout installation. The most recent application has been at an Asda store in Havant, Hampshire, where FreeSpace have ﬁtted an IP67rated point to point wireless Ethernet bridge system with in-built hardware encryption. At the Havant store, FreeSpace are transmitting a constant feed from a Samsung IP-addressable dome camera which can be monitored live or viewed retrospectively. The FreeSpace units have been supplied by the company’s distributor, Anixter, and the installations performed by Scope Electrical Contractors who specialise in CCTV systems in the petroleum sector. Return on investment has been immediate, the ﬁrms say.
In the channel Karl Belmar, Operations Director at FreeSpace, said: “A conventional approach at the Havant project would have seen a single cable run of just 900 metres produce a bill running to many thousands of pounds after a channel had been dug, services suspended and the forecourt closed to customers. While this wireless technology has commercial beneﬁts for Asda, the footage also assists the client in exercising duty of care to colleagues. On arrival at the station, unaccompanied tanker delivery staff can advise store management of their presence and be observed in case of accident or equipment malfunction.” The FS2000-cp bridge kit used here

is a distribution-focused product that is supplied as a conﬁgured pair. Essentially, the customer need only provide a mains power source on either end and point the devices at each other, adding encryption and passwords as required. The solution has an integrated 23dBi antenna and is optimised for Fixed Wireless Access (FWA). At the Havant store transmission distance was minimal, but line of sight was far from ideal with a 25-metre height difference between the ﬁlling station and the main store as well as obstruction from trees. However, the radio supplied as
standard offered connectivity beyond location requirements, it’s claimed. With no obstruction the units can cover up to 40km. The installer did a site survey taking account of likely seasonal changes in foliage and aesthetics when mounting units on the retailer’s store front. Local area scans were performed with attention paid to a satellite transmission mast no more than 50m from the forecourt. FreeSpace delivered full spectrum analysis and wireless scanning across the 5GHz U-NII and ISM spectrum, these services being part of the company’s standard site survey.
