CommScope’s Node AM is a universal multiband, multiservice digital repeater capable of meeting the needs of rail operators in challenging multiband, multi-operator applications.
Mobile coverage on trains is now a key requirement for passengers. Understandably so, as a high percentage of rail users are business travellers who want to make the most of their commute. They want reliable voice and data coverage, and rail operators that consistently provide this will be their preferred choice for travel.
However, trains present extremely challenging radio frequency (RF) environments, as changing terrain and signal levels across the various networks can make it difficult for operators to provide the coverage and service customers expect.
CommScope provides solutions designed to meet the communication challenges specific to railways around the world, and our extensive portfolio of solutions is built upon decades of industry experience and leadership.
Our Node AM is a universal multiband, multiservice digital repeater capable of meeting the needs of operators in challenging multiband, multi-operator applications, whether the requirements call for 4G (LTE/LTE-A), 3G (UMTS), or 2G (GSM, GPRS, EDGE), or a combination of all.
Node AM seamlessly links to CommScope’s integrated management and operating system, A.I.M.O.S., the repeater’s intuitive auto setup wizard and help screens enable easy system configuration, minimising setup time and reliance on bulky test equipment, while advanced quality of service (QoS) measurements and reports – including inbound and outbound measurement of channel power, pilot power and received signal strength indication (RSSI) – verify ongoing system operation.
The digital repeater supports up to four frequency bands in a single chassis. Its modular, scalable architecture enables users to modify, upgrade or expand the repeater platform in minutes by simply adding RF cards and software features, and importantly, without increasing installation space.
Furthermore, the platform is available in medium and high-power classes, making it ideal for driving radiating cable and passive distributed antenna systems with the lowest possible power consumption.
Node AM excels in a wide range of wireless coverage applications including, but not limited to:
Arriving and Departing Train Stations
When arriving at or departing from a train station, a digital repeater must deal with the strong RF signals coming from nearby base stations. Node AM’s trailing feature enables the repeater to adapt to the environment, continuously changing its gain and noise level to prevent interference.
Passing Green Field Areas
Node AM’s high dynamic range allows for operation in the presence of strong transmitters without the need for external filtering or attenuation. Its advanced capabilities allow only the desired signals to be transmitted, resulting in optimum utilisation of its output power capacity.
Entering a New Country
When crossing into a new country, Node AM’s embedded GPS receiver allows automated frequency allocation based on GPS position. With the ability to add all worldwide sub-band configurations, the digital repeater provides a standard solution for all train manufacturers and wireless operators.
