Cobham Wireless’ range of multi band digital off air repeaters provide cellular coverage in small and medium sized buildings. Making use of the DSP (digital signal processing) architecture the products can be configured for single or multi operator use and support all the major cellular frequency bands including 900MHz, 1800MHz, 2100MHz and 2600MHz and all wireless technologies including GSM, EDGE, DCS, CDMA, WCDMA and LTE. The devices support up to four frequency bands and are easily configured either locally or remotely via a simple GUI web interface or using the AEM network management software. Such is the flexibility of the architecture that frequency “re-farming” is easily achieved as the products allow multiple wireless technologies to run concurrently in the same frequency band. A unique feature of Cobham Wireless’ multi band products is an innovative IMOP (Interference Mitigation Oscillation Prevention) mechanism that ensures that the devices will never oscillate something that can happen with other repeater systems. Cobham Wireless’ multi band portfolio provides mobile operators and enterprise customers with high quality, low maintenance coverage solutions for most building environments.
