TE Connectivity aims to bring 5G mobile communications technology to the rail industry in order to help transform riders’ experience. The new wideband MiMo rooftop antennas have been engineered for use in 5G communications on overground and underground trains, as well as metros, trams and buses. The different models incorporate one or two antenna elements for MiMo operation to provide a broad frequency response from 698MHz to 6000MHz. These antennas also fit legacy communications (2G/3G/4G), Wi-Fi, WiMax and GNSS (including GSMR). They meet the EN 45545-2 standard covering fire performance of materials and components for trains, as well as EN 50155, which covers various aspects of electronic equipment used in railway rolling stock.
IP69 protected, they can resist high-pressure water jets. DC-grounded antenna elements in the rooftop antennas deliver voltage protection in case of catenary line drop up to 40kA, 100ms. The antennas can be mounted on non-conductive surfaces thanks to an internal ground plate. Moreover, the ceiling-mountable circular onboard Wi-Fi antenna offers up to 4x4 MiMo Wi-Fi coverage. With a frequency response range from 2.4 to 2.5GHz and 4.9 to 6GHz, the antennas fit the IEEE 802.11ax standard. They provide data throughput four times faster than earlier antennas in congested environments, together with 40% higher peak data rates. With a low profile (height is 30 mm), they are supplied with flame retardant CS23 coax cables (EN45545 compliant), and their white radome is also flame retardant.
