Following our blog on cellular vs Wi-Fi airspace management we felt a more in-depth look at effective management of licence exempt spectrum within buildings was needed. For licenced spectrum, management is the responsibility of Ofcom, so interference can be reported directly to them. However licence exempt spectrum is not regulated, so it is up to the landlord to be proactive to minimise interference, and we want to help by explaining exactly what is required.
Within a building, there is the potential for multiple different wireless devices being used, from Wi-Fi to secure 2-way radios, many sharing the same frequencies. This situation becomes even more complex when the building is occupied by a number of different tenants, particularly when these are businesses, each with their own Wi-Fi and other wireless services. Examples of this are airports, shopping centres and shared office buildings. If left unmanaged each tenant Wi-Fi, for example, is highly likely to leak outside their premises and cause interference with services used by other tenants. To ensure this does not happen landlords need to take control of their airspace for the benefit of all wireless users, through the creation of an airspace management process.
The general tasks are as follows:
- Capture the details and plans for all wireless services which use licence exempt spectrum within the building.
- Assess the risk of interference and recommend mitigating action.
- Update tenant lease agreements to enable the landlord to control airspace usage.
- Create an airspace management process to assess tenant proposals to modify or add their own wireless services.
- Operate the airspace management process and perform regular audits to ensure compliance with lease agreements.
We advise that the airspace management process should be embedded within existing processes e.g. for the approval of shop fit-out. Additionally we recommend that the process is in place as early as possible, before interference becomes a serious issue. Set up and operation of the process is generally outsourced by the landlord to a third party such as iWireless Solutions, as it requires wireless technical expertise and equipment.
