Gsm-RChannel Selective repeaters for GSM-R provide a quick and cost effective method of extending coverage in new or existing GSM-R networks. The operators can expand a base station’s service area by filling in coverage holes caused by obstacles such as buildings, hilly terrain or tunnels.
Frequency Translating repeaters and Band Shifting repeaters provide output power levels comparable to base stations in GSM-R networks. They consist of two units, a Donor
Unit placed close to the BTS and a Remote Unit at the selected site. The link between the two units is run on another frequency or another band; hence the antenna isolation require-ments are significantly reduced.
Fibre-fed repeaters are designed with tunnel coverage in mind. The
repeaters are connected to the base stations via an optical master unit which converts the RF signal from the base station to an optical signal which is then transmitted to the repeater via a fibre-optic cable. The repeaters can be installed up to 20 km away from the base station.
onBoardThe Axell Wireless OnBoard solution is a multiband, multi operator repeater which is small and flexible specifically de-signed to provide coverage within train carriages. It is designed to withstand the physical environment inside a train and meet all required standards of train equipment. The OnBoard repeater can be equipped with any combination of the frequency bands; GSM-R, GSM900, GSM 1800 and UMTS.

The forthcoming ambition to roll out the European Rail Traffic Management System (ERTMS) with uniform and unique signalling standards throughout Europe puts new higher requirements on the GSM-R systems. Continuous and redundant coverage along all railway tracks including good tunnel radio coverage are essential and this is at the very core of the Axell Wireless competence area provided through a complete dedicated GSM-R product portfolio.
Axell Wireless’ expertise and broad product portfolio within tunnel radio coverage for any frequency band – CSR, TETRA, GSM-R, GSM 900, GSM 1800 or UMTS, is a great advantage when a seamless result is of great importance. The use of repeaters in tunnel radio applications has shown to be ideal because of space and RF propagation issues. A typical installation of radio coverage in a longer tunnel uses optical fibre fed repeaters and radiating cable. The repeaters at the mouth of the tunnel or located within the tunnel can either be fed via optical fibre from the nearest base station or via an off-air repeater. Full system redundancy can easily be achieved if required. Shorter tunnels can be covered with antenna fed repeaters.

tEtRaIn the TETRA area Axell Wireless offers a comprehensive range including fibre-fed repeaters as well as off-air repeaters. For large confined areas such as tunnels, we offer a reliable solution with fibre-fed repeaters linked to an optical master unit, OMU. Over 20 repeaters can be connected to the same OMU and be installed up to 20 km from the base station. Redundancy in the system can easily be accomplished. Off-air repeaters can be used as stand alone repeaters to cover a limited area or as input to a fibre-fed system.
sERVicEsThrough our dedicated Field Services team, Axell Wireless can provide on-site services for systems including system design, installation supervision, commissioning and integration as well as undertaking training and maintenance support.
