The limitations of DAS (Distributed Antenna Systems) in terms of cost and complexity are well known, but alternatives such as small cells and WiFi have not been able to dislodge DAS from its heartlands in large venues, transport hubs and campuses. Indeed, deployment of DAS is rising as the need for reliable voice and data in such locations increases; as new venues get built round the world; and as the technology itself evolves with enhancements like digital DAS. Alcatel-Lucent is tapping into all those trends with its Radio Frequency Module (RFM), a low power LTE interface card which can connect to any vendor’s DAS system, providing a small-footprint radio equipment which costs up to 90% less to run than traditional…
