CAM Hosts Digital DAS Workshop, London

Published: 10 June 2015 Digital DAS Conference

On the 4th June 2015 CAM hosted an open Digital DAS Workshop in London, bringing together UK mobile network operators (MNOs) and some of the world’s leading equipment vendors of digital DAS technology.

“CAM identified a common interest among the mobile network operators to better understand digital DAS technologies,” comments CAM Group Managing Director, David Pearson. “We believe that there is a need amongst industry leaders to work together to promote future technology and we sought to facilitate this by bringing all players to a common event.”

To date in-building systems have primarily been analogue, and while this technology has served the mobile industry very satisfactorily, eco-demand and technology advancement have enabled the development and production of the next generation of DAS using digital techniques.

Ken Ng, CAM’s Non-Executive (Technology), tells us “Digital DAS offers the benefits of ‘SON like’ features for easy deployment and performance optimisation and the possibility of resources routing to overcome traffic congestion. In addition, with the adaptation of CPRI, digital DAS may help the realisation of RAN virtualisation, which may be employed for 5G.”

Dedicated to achieving the highest levels of quality for consumers across their network, the representatives from the MNOs were provided with an opportunity to gain a deeper understanding of current DAS equipment in the marketplace. The event also allowed vendors the opportunity to showcase new innovative solutions in front of key technical decision makers.

Presentations were made by KATHREIN-Werke KG, Axell Wireless, Dali Wireless, Huawei, Zenic8 and Arqiva to UK MNOs, T-Mobile NL, and wireless solution providers. Each vendor gave an hour’s presentation and Q&A session, run individually to avoid any concerns around commercial sensitivity. A list of technical questions was sent to each supplier in advance to facilitate discussion at the workshop.

“Despite most of UK venues being equipped with traditional, analogue DAS,” comments Ken Ng, “following the workshop, CAM UK’s view is that there is real potential for digital DAS in the new large commercial buildings being constructed in London. There may also be a market as the front-haul for small cell deployment. This will require SON features to work with the MNO’s RAN for effective and efficient deployment of large numbers of small cells.”

Digital DAS will most likely become the technology of choice in the UK within the next 18-24 months.
