BT & Stoke validate five new LTE deployment options

Joint lab tests show potential for stand-alone Security Gateways in LTE networks


SANTA CLARA, CALIF., February 27, 2012: – BT’s Advanced Research Mobility Team and mobile broadband gateway developer Stoke Inc. have completed joint lab trials investigating different deployment models for LTE networks. 


The tests, initiated in February, 2011, were designed to explore potential synergies between mobile and fixed networks and examine a variety of options for LTE transport connectivity.


“This research with Stoke has enabled us to determine some high-potential opportunities to develop innovative services for current 3G environments and opportunities for evolving the architecture to 4G, said Chris Bilton, Director, Research & Technology, BT. “The program findings, especially the proof of vendor interoperability, have provided invaluable insights which will help formulate next steps in proving our findings.” 


Stoke’s Security eXchange was used to examine aspects of scalability, enhanced security, and multi-tenant network sharing scenarios, and acted as an anchor device in enabling the demonstration of different architectural strategies for LTE deployment. 


BT and Stoke are now able to define new architectural strategies that provide important information for LTE license holders.  “With spectrum owners looking at options ranging from build-own-operate to complete outsourcing arrangements, there are many unanswered questions.  The test results shed much-needed light onto the feasibility of LTE rollout options, and point the way to some viable alternatives,” said Dave Williams, Chief Technology Officer at Stoke “We are very pleased to support BT in extending its research into areas that will rapidly add value to its business divisions and customers. Additionally, the trials have helped us to develop advanced new features for our platform.” 


The tests utilized equipment from a variety of vendors; Stoke’s Security eXchange successfully demonstrated seamless interoperability and transparency with all vendors’ equipment including RAN, backhaul transport, caching, timing and synchronization and EPC.  The results also highlighted the value of: selecting multi-vendor, best-of-breed equipment to enable a variety of flexible deployment options; validation of the imperative for scalable security in mixed networks; and the advantages of the standalone secure aggregation gateway in enabling distributed deployment of the function at different points in the network. 


The growth in LTE deployments, migration challenges and the pros and cons of an embedded versus a standalone approach to security within the EPC core network  is explored in an IDC white paper,  sponsored by Stoke, ‘The Role of Best-of-Breed Solutions in LTE Deployments published February 23, 2012The paper[1] also outlines some of the opportunities created for operators in deploying a standalone approach. 


“As IP injects itself deeper into service providers’ LTE networks, operators face new and unfamiliar challenges,” said John Byrne, Research Director, Wireless Infrastructure at IDC Research. “In the specific area of security, operators must keep pace with growing network loads, unpredictable traffic patterns and increasingly complex network architectures with the result that flexibility and scalability are becoming key requirements. We believe that operators taking a long-term view toward maintaining high performance as LTE network loads increase may wish to consider adopting standalone solutions to help manage growing signalling loads, ensure the highest levels of security possible, and maintain the ultra-low latency performance that LTE can deliver.”


Stoke also demonstrated the secure backhaul capabilities of its Security eXchange during the successful Multi-Service Forum Voice over LTE trials in September, 2011 further adding to the number of LTE vendors proven to interoperate with the Stoke Security eXchange.  The product was recently named winner of Mobility Tech Zone’s LTE Visionary Award and was a finalist in the November, 2011 Light Reading Leading Lights awards. Stoke will showcase the Security eXchange together with its Wi-Fi eXchange and Service eXchange systems together with new offerings at Mobile World Congress, Barcelona, February  27 – March 1, 2012.
