JMA Wireless compression connectors ensure mobile comms in 2.3 km tunnel

February 27, 2017 // By Jean-Pierre Joosting
JMA Wireless is ensuring the integrity of the wireless network in the King Willem-Alexander Tunnel, in the Netherlands, with its easy-to-install, PIM optimized compression connectors that ensure superior connectivity in harsh, high vibration environments.

Built to relieve traffic congestion, the tunnel is comprised of four stacked tunnel tubes, with two above and two below. In addition, a multi-lane roadway, pedestrian paths and greenery lies above it. Tunnel environments have an increased level of vibration and environmental conditions that can easily result in degraded performance at the connection points to the equipment. To ensure the wireless network is resilient to these factors, system integrator, VolkerWessels Telecom (VWT), turned to JMA Wireless for the industry’s most resilient compression connector technology. It was deployed across hundreds of connection points in radio transmission lines throughout this distinctive 2.3-kilometer tunnel located in the city of Maastricht in the Netherlands.

VWT selected JMA Wireless’ patented compression connector technology to ensure superior connectivity throughout the tunnel system for four mobile operators (KPN, Vodafone, T-Mobile and Tele2) four bands (800, 900, 1800 and 2100 MHz), and six sectors.

Even excessive levels of vibration caused by the high amount of daily traffic in the King Willem-Alexander Tunnel has not affected the dependability of the JMA Wireless compression connectors.
