As part of the Digital Dividend Review (DDR), Ofcom commissioned Cobham Technical Services – ERA Technology to carry out a measurement study in order to answer the following questions:
- Can localised interference from non-co channel LTE handsets situated 2.5 m or more from the TV receive system be sufficiently high as to cause interference to either the TV video or audio output or cause any degradation in the receiver sensitivity in a typical domestic installation?
- If any form of interference is experienced under what circumstances does this occur (e.g. distance, image channel) and where is the main point of breakthrough (e.g. cable or TV)?
- Are there simple, cost-effective practical measures that may be used to overcome any problems experienced (e.g. better screened fly-leads and the fitting of a filter in the aerial downlead)?
