Digital DAS (Distributed Antenna Systems) IntroductionUnder ever-changing spectrum allocation caused by Carrier M&A, unceasing bandwidth demand to meet voice and high speed data requirements and fast evolving mobile technology, the need for true multi-band inbuilding solution has become paramount. Thats where Digital DAS comes in!

Digital DAS was designed to serve 2G, 3G or WiMAX (or even LTE) and WiFi simultaneously. It offers all the benefits ofstate of the art inbuilding solution, enabling any carrier to implement multi-band system for areas between small size building up to 350,000 square feet. Highly economical and remarkably easy to migrate and expand spectrum. Digital DAS delivers unparalleled high performance that similar products simply can not match. It is monitored and controlled by web-based network management SW. Flexible configuration of Digital DAS gives options to carriers who deploy multi-band inbuilding solution as well as for multi-operator installation such as public venues like airport, arena, station.
