    -  The MSF event, a global first to focus on multi-vendor, multi-operator
       interoperability spanning multiple sites, promotes and fosters
       compatibility and interoperability with leading network equipment
       vendors and operators including Vodafone, China Mobile, NEC, Starent
       Networks now part of Cisco, Huawei, ZTE, Alcatel Lucent, Agilent and

       3GPP System Architecture Evolution.
    -  Among the products undergoing interoperability testing at the event
       are the standards-based Bridgewater(R) Home Subscriber Server for HSS
       1.0 (S6a interface), the Bridgewater(R) Policy Controller for PCRF 4.0
       (Gx, Gxc interfaces), and the Bridgewater(R) 3GPP AAA Interworking
       Module for 3GPP AAA 8.3 (S6b, STa interfaces).
    -  Participation underscores Bridgewater's leading role as the only LTE
       control plane specialist at the event. The company also recently
       announced a multimillion dollar LTE win at MetroPCS as well as LTE
       trials with five Tier 1 mobile operators in Asia Pacific and North and
       South America.
