1800MHz

Cobham Wireless’ range of DSP (digital signal processing) 1800MHz digital off air repeaters provide cellular coverage in small, medium, large and campus style buildings, inside tunnels and metros and into remote or rural communities. The product range covers the whole 75MHz DCS 1800MHz band and supports multiple wireless technologies including GSM, EGSM, CDMA, WCDMA and LTE. Thus our 1800MHz products allow operators to easily “re-farm” spectrum running parallel wireless technologies alongside each other if required. No hardware changes are required due to the unique SDR (software defined radio) architecture of the product range. Devices are easily configured either locally or remotely via a simple GUI web interface or using the AEM network management software and incorporate an innovative IMOP (Interference Mitigation Oscillation Prevention) mechanism that ensures that the products will never oscillate something that can happen with other repeater systems. The 1800MHz portfolio includes low, medium and high power products which can be used inside or outside buildings. A unique feature of our product design is that cooling fans are not used in externally based products thus increasing MTBF and resilience.
