Until now, when one femtocell was near either another femtocell or an outdoor macrocell base station, radio wave interference would distort communication signals.
In home wireless environments, this technology will enable high-resolution video streams and allow applications such as online games to run smoothly.
Details of this technology will be presented at the 24th Annual IEEE International Symposium on Personal,
Femtocells are small cellular base stations that enable communications to run as fast as conventional outdoor macrocell base stations in terms of their maximum communication speed. With an indoor femtocell, devices need not communicate with outdoor macrocell base stations, resulting in better quality communications. In addition, because the wireless frequency band can be restricted to just a few users, there can be dramatic improvements in communication speeds of up to ten times or more.
Femtocells, therefore, represent a solution to dead zones, where radio waves cannot reach mobile phones, as well as to communications traffic caused by an overall increase in wireless communication usage.
Macrocell base stations are spaced in accordance with meticulous cell designs in order to prevent radio wave interference from other macrocell base stations. Femtocells, by contrast, are placed in users' homes, and with large numbers of them it can be difficult to reduce radio wave interference. As a result, when one femtocell is near either another femtocell or an outdoor macrocell base station, radio wave interference distorts communications signals. Specifically, there are the following three types of potential interference.
Nearby femtocells interfering with a femtocell connected device
In this case, the communications speed of a device connected to a femtocell is reduced because of radio waves from another nearby femtocell.
Nearby macrocell base stations interfering with a femtocell connected device
In this case, the communications speed of an indoor femtocell connected device is reduced because of radio waves from a nearby macrocell base station.
