Speaking to the press, Mr. Vijay Kulkarni, CEO of the firm stated, ?It is essential for Mass Transit Systems to keep important radio communications back links inside of subway tunnels, stations and pubic access areas. Contemporary technologies permit extending the aboveground cellular radio coverage to the underground seamlessly and price-successfully. Irrespective of no matter whether the communications system is higher than ground or below ground, several of the needs stay the identical: Tunnel radio communications for initial responders as well as method maintenance and operation personnel, Inter-company conversation and interoperability in tunnels through centralized smart command and manage middle, growing homeland protection issues and require to entry voice and information quickly in tunnels, crisis alerts and community protection worries in tunnels in the course of emergencies, automated motor vehicle area and innovative mobile information terminals inside tunnels and following train arrivals information in excess of the radio back links.

To fulfill the previously mentioned requirements tunnel radio techniques can encompass a lot of technique systems ? deciding on the correct one particular is at times not an straightforward process. And some of the needs of tunnel radio programs are: Ongoing coverage over the entire duration of the tunnel i.e. no useless locations, distinct audio during with little or no interference, reliable system procedure beneath severe tunnel environmental situations, trunked radio channels across numerous bands, ease of method operation and servicing.?

He extra, ?GL Communications offers program design and style and technical specifications for Metro Subways to increase program-vast UHF radio communications within the tunnel and underground stations. We also provide development control that incorporate inspection and good quality assurance services of the freshly put in redundant off-air radio program interfaces, fiber-fed bi-directional amplifiers and RF distribution infrastructure within the tunnels and underground station platforms.

GL?s engineers using RF measurement techniques analyze the signal strength inside of tunnels and identify areas of very poor RF coverage. Our analysis and engineering help assisted numerous clients implement remedial steps to increase the RF protection inside of the metro tunnels.?

Mr. Kulkarni more added, ?GL provides technique design and style and technical specs for radio communications of aboveground, garage repeaters and underground programs inside tunnels for transit networks. Our companies consist of surveys, scientific studies, description, definition and documentation of existing and proposed systems.?
