Wireless Base Station Evolution 2G and 3G Colocation Solution For LTE Access

Wireless infrastructure equipment manufacturers must balance minimizing deployment costs against fulfilling demands for next generation network services. Significant infrastructure investment in recent years has resulted in amortization playing a key role in future network evolution. Reusing existing infrastructure allows equipment manufacturers to offer operators a road map for long term evolution (LTE) that will reduce operating and capital expenditures. Freescale Semiconductor’s solutions enable network planners full flexibility when upgrading the GERAN or UTRAN to offer users additional services. This paper details the existing protocol and interface requirements for transport on 2G- and 3G-wireless base stations. It also presents Freescale’s solution for extending the lifetime of deployed equipment while also solving next generation data rate and feature set requirements, thus creating an extensible, IP-anywhere mobile network capable of offering ubiquitous mobile broadband.
