Two antennae enhance connectivity for public transportation

Two antennae for mobile connectivity use multiple input multiple output (MIMO) technology for enhanced connectivity in low profile indoor WiFi antenna applications in rail vehicles and buses.

TE Connectivity says that the MIMO antennae provide the high levels of internet availability that passengers expect while travelling. The first is a low-profile, plug-and-play WiFi antenna for indoor use that is mountable almost anywhere in a vehicle. The second is a multi-service antenna for outdoor use, combining mobile connectivity, global positioning and WiFi functionalities in one robust device. The integrated MIMO technology delivers enhanced connectivity by dividing data streams (multipath propagation) and using up to four antennae for signal transmission.

The indoor antenna is designed with a low profile as space is often limited in vehicles, especially in height restricted double-deckers. With a diameter of 115 mm and a height of only 30 mm, the WiFi antenna is compact and can be installed in confined spaces. The built-in ground plane allows it to be placed anywhere in the vehicle, even on non-conductive surfaces. The material used in flame retardant.

The antenna can be equipped with a 3×3 or a 4×4 MIMO antenna. The plug and play radio connection can be established though a SMA or right angle n-type coaxial connector.

The multi-service MIMO antenna from TE Connectivity provides three functions in one device, delivering GSM (up to LTE), global positioning (compatible with GPS, Glonass, Galileo, and Beidou standards) and WiFi connectivity in a robust housing. Designed for outdoor use, the antenna is in the shape of a shark fin, conforms to the IP66 standard and even protects against water jets coming from high pressure cleaners or automated washing. The over-moulded surface withstands direct sunlight, making the product suitable for rooftop mounting. Only one M18 split nut is needed to fix the antenna.
