Bytemobile and F5 Scale T-Mobile 3G Network Capacity To Address Explosive Growth in Data Traffic

Bytemobile and F5 establish worldwide partnership focused on increasing efficiency of network operations to maximize capacity and agility of mobile network operators

Bytemobile, Inc., the global leader in mobile internet solutions for wireless network operators, and F5 Networks, Inc. (NASDAQ: FFIV), the global leader in Application Delivery Networking, today announced that Bytemobile has enhanced its existing deployment at T-Mobile International with an F5 solution that provides scalable network capacity to serve the mobile content delivery needs of T-Mobile customers. In addition, Bytemobile and F5 have formed a partnership focused on delivering scalable and secure mobile internet solutions to wireless network operators worldwide.

For T-Mobile International, which serves approximately 95 million subscribers across its European operating companies, Bytemobile has integrated the F5 VIPRION ® on-demand Application Delivery Controller with its Unison™ Mobile Internet Platform installed in the core data path of the network. The result is increased network scalability, availability and performance for the delivery of value-added mobile data services to T-Mobile customers.

Bytemobile and F5

F5 & Bytemobile provide compelling application performance benefits for mobile network operators and users

T-Mobile International indicated that it has experienced significant growth in data adoption and usage for both mobile broadband and mobile internet applications. As a result, the volume and mix of its network traffic has changed dramatically over the last year. Bytemobile's internet gateway, traffic control and optimization solutions, now combined with F5's Application Delivery Networking capabilities, have enabled T-Mobile to scale the capacity of its 3G network in line with consumer demand.

Under the terms of its global systems integration and reseller agreement with F5, Bytemobile integrates F5® BIG-IP® and VIPRION solutions with other third-party system components-such as industry-standard server platforms, operating systems, switches, and application software-around the Unison software platform in its customers' networks. Bytemobile selected F5 for its specialized ability to deliver high availability and high throughput for complex applications in very large-scale networks with traffic flowing through multiple data centers.

The F5 VIPRION system is architected to deliver the intelligence and performance needed to scale next-generation networks and applications, enabling wireless network operators to effectively handle explosive growth in data traffic. This complements Bytemobile's data reduction and service control capabilities, which enable operators to manage the impact of not only traffic growth but also changing traffic mix on existing network infrastructure, while maintaining high quality of service to subscribers.

Economic Imperatives

"The Apple iPhone, USB dongles, mobile video, and other factors have caused data traffic on tier-one networks to grow at rates of 10 to 15 percent per month," said Adrian Hall, Chief Marketing Officer at Bytemobile. "In some cases, 1 to 2 percent of users are consuming up to 50 percent of a network's traffic. Now more than ever, operators need to protect and extend their network assets, especially given the current global economic environment. They also need to minimize churn by delivering rich, personalized data services that build brand loyalty with their customers."

"Our partnership with Bytemobile helps us assure mobile network operators that their networks will not only support their current business objectives, but will also rapidly respond to new revenue opportunities," said Dan Matte, SVP of Marketing and Business Development at F5. "Now operators can benefit from the scalability, availability, and IT agility that F5 has traditionally delivered to large enterprises and telecommunications networking companies. We look forward to working with Bytemobile to help operators worldwide increase their competitive edge and enrich their data services for customers."

T-Mobile has been a Bytemobile customer since 2002. Under a group supply agreement, T-Mobile International selected Bytemobile's Unison Mobile Internet Platform as the consolidation node for its Mobile Internet Gateway (MIG). Bytemobile solutions on the Unison platform are deployed at T-Mobile operating companies in Austria, the Czech Republic, Germany, the Netherlands, and the United Kingdom. Bytemobile has selected the F5 VIPRION system to meet the scalability and availability requirements of the Unison platform at these T-Mobile sites.
