JMA Wireless provides wireless connectivity for King Willem-Alexander Tunnel
February 28, 2017 – JMA Wireless, a global provider of wireless communications solutions, is ensuring the integrity of the King Willem-Alexander Tunnel’s wireless network with its compression connectors. 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 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 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.
In addition to being PIM optimized, the JMA Wireless connectors allowed the VWT team to complete the installation in a short eight-week timeframe. JMA Wireless compression connectors are a one piece solution, including both the mating interface and the cable attachment, that utilize standard tools for installation. Time in the field was not spent assembling piece parts. Finally, the cold winter temperatures were not an issue either since the connectors can be installed and serviced in a temperature range from –40° C to +85° C.
