electrical system design brighton and hove

Primary school, Brighton

Our client had gained funding from the local authority in order to install a new secure wireless network throughout the school to operate a new intranet. Each member of staff had been issued with their own tablet which among many other things acts as a teaching aid, planner and register. In order for this new system to work the entire school grounds had to be covered by the same wireless signal, this meant that over thirty individual wireless access points had to be installed in areas both inside and out that had been pre-assessed for optimum coverage. As well as the access points we had over 3.4km of Cat6 structured cabling to run in order to link each access point to a central location. The

work had a strict schedule of one week from start to completion as it was decided that carrying out the work during term time with children in the building was a high risk activity, it is for this reason that the five day half term was selected as an appropriate time to carry out the installation work.

In order to keep data loss to a minimum the task of running such a large amount of cable had to be strategised so that individual runs between access points and network switches were kept below 90m, this involved careful planning and preparation. We also had to ensure that at no point during a cable's run was it going to be subject to inteference from other low voltage cabling. We carefully selected two sites to mount and install new cabinets for termination and switching, this was also in order to keep data transfer speeds high and loss to a minimum. We found

that one central location, no matter where it was placed would result in at least one run being over 120m which would have been unnacceptable.

Our main method of power distribution to each internal access point was with the use of PoE (Power over Ethernet) network switches, we combined this with PoE injectors for the external access points as being 'AT' rated they require a higher power in order to project a stronger signal over a further distance. Each cabinet housed its own power supply, PoE switch and any neccessary injectors, this was then linked back to the central network hub.

Over the week our team of six, comprised of electricians and structured cabling engineers delivered a fully functional system that was installed to plan and tested successfuly upon completion. Damage to the existing building structure was kept to a minimum and where created was made good. We ensured that fire protection was not compromised by making sure that new fire barriers were put in place where neccessary. When the project was completed the client was happy with the work carried out. We did suffer one minor teething problem in getting the old network and new network 'talking to each other' but when a connection was established the client was very pleased with how effectively the new system delivered connectivity over and above what was originally in place.
