Optimised solution for mobile wireless applications Cobham Wireless’ new generation digital OnBoard Repeater is a flexible multiband coverage solution optimised for mobile wireless applications on board trains, vessels or other moving vehicles.
When space is limited The new platform offers advantages for all stakeholders; mobile operators can enjoy an increase in throughput, versatility and customer satisfaction, train operators can reduce the space required for telecoms equipment and for manufacturers installation is simpler and can be cheaper.
New Design The totally new design puts focus on today’s requirements: size to match with various installation environments even when space is limited, minimized power consumption and heat dissipation, multiple digital filters for sufficient splitting of multiple operators and technologies and fast algorithms for gain adaption and isolation control, fit for high-speed train deployment.
Perfect for high-speed train deployment
How does it work?
The Intelligent Digital-OnBoard Repeater is connected to one donor antenna placed outside of the vehicle or vessel and the leakage cable or antennas in the area to be covered. The target is to overcome the high penetration losses of the thermal insulated windows or metal wall material and provide the mobile device with a coverage level equal to the outside.
A prominent located donor antenna further helps to improve the signal level. GPS based changes of the band configuration, gain, power and frequencies is supported. The exact position of the repeater can be monitored remotely. The units connect through IP or wireless modem using standard SNMP.
An internal web server provides an efficient user interface locally and remotely. Fleet management can be done using a SNMP umbrella system, or, more comfortable, using Cobham Wireless’ AEM (Active Element Manager). To minimize the risk of interference with existing GSM-R infrastructure Cobham Wireless offers a dedicated optional notch filter.
