Wednesday, 10 June 2015
12:00 – 13:00

Chair: Bryn Jones, Three UK CTO

Panelists: Fotis Karonis, CTO, EE
Brendan O'Reilly, CTO, Telefonica UK Ltd
Ed Tiedemann, EVP, Qualcomm
Wen Tong, CTO, Huawei

Abstract: CTOs are currently experiencing significant data traffic volume in their mobile networks. Capacity is becoming one of the major challenges. Mobile Networks as they are today will not be able to maintain a high Quality of Service in the future. Consequently, CTOs must evolve their networks to offer higher capacity and more reliable data services. In this forum, five CTOs from EE, O2, Three, Qualcomm and Huawei will address the question – What is next for mobile networks?
