Celluar Digital Repeater
Wireless repeaters amplify cellular signals inside large building such as airports, shipping malls and other public places and have thus become a mainstay of the wireless infrastructure network. In the consolidation of cellular service providers in recent years, however, some service providers have acquired non-contiguous spectrum bands. This considerably complicates the amplification of a provider's multiple spectrum bands with a single wireless repeater device.
Beause service providers are required to selectively amplify their own spectrum bands and avoid interfering with bands owned by other providers, cellular repeaters must be able to filter out or suppress wireless signals in bands owned by other entities. These bands can often be adjacent to a channel that is being amplified. Increasingly, equipment manufacturers are turning to the high-level precision and repeatability of digital signal processing techniques to quickly develop and bring to market signal repeaters for wireless infrastructure applications. In addition, employing digital technology can significantly reduce bill of materials, development and manufacturing cost over an analog repeater implementation.
