Rail Antenna vendors | Railway rooftop antennas 5G GSM LTE WiFi

This page mentions Rail Antenna vendors or Rail Antenna manufacturers. It mentions popular vendors of Railway rooftop antennas used for trains with 5G NR, GSM (2G), GSM-R, UMTS (3G), LTE (4G), GPS and WiFi (i.e. WLAN).

Rail Antenna for trains

The rail antennas are used for indoor and outdoor applications. These antennas are designed as per compliance specifications outlined in EN50155 standard for mounting on trains and vehicles. This railway stanadrd specified various approval tests for rail antennas as well as other electronic equipments required on a train. The tests include performance over wide temperature range (-40 ^oC to +85 ^oC); EMC test, shock vibration and bump test etc.

Indoor antennas are designed for WLAN frequency bands (2.4 GHz and 5.8 GHz) to provide wifi connectivity with smart devices. These indoor antennas also support various cellular bands viz. 5G, LTE 700/800, GSM-R, GSM 900/1800, UMTS (1885 to 2170 MHz) etc. Refer article on WiFi on trains covering various network architectures to use internet on trains at metro stations and rail tunnels.

The generic specifications of indoor rail antennas used for wifi applications are as follows.
• Frequency band : 2.4 or 5.8 GHz
• Polarization : Vertical
• Pattern : Omni-directional
• Gain : 9 dBi (For 2.4 GHz) or 10.1 dBi (For 5.8 GHz)
