Ericsson LTE Radio Access Network

LTE is the next step in the technical evolution of 2G/3G networks. It offers superior user experience with simplified technology for next-generation mobile broadband.

LTE benefits

The internet generation is used to having broadband access whenever and wherever—not just at home or in the office. People already browse the internet or send e-mail using HSPA-enabled notebooks that replace their fixed DSL modems with HSPA modems or USB dongles. Likewise, they send and receive videos and music using 3G phones. With LTE, the user experience will be even better—it will enhance capacity-demanding applications such as interactive TV, mobile video blogging, advanced games and professional services.

Performance

LTE is specified by 3GPP to provide downlink peak rates above 100Mbps. The current standardization of LTE allows for speeds more than 300Mbps and we have already demonstrated corresponding peak rates. Radio access network (RAN) roundtrip times will be less than 10ms, meaning LTE, more than any other technology, already meets key 4G requirements.

Capacity

LTE supports flexible carrier bandwidths from 1.4MHz up to 20MHz. It is being deployed in new spectrum and will offer optimal capacity when the full 20MHz bandwidth is utilized. LTE also supports frequency-division duplex (FDD) and time-division duplex (TDD). Several paired and unpaired spectrum bands have been identified by 3GPP. Operators can thus introduce LTE in new bands where it is easiest to deploy 10MHz or 20MHz carriers and eventually deploy LTE in all bands.

Simplicity

LTE radio network products will have several features to help simplify and reduce the cost of building and managing next-generation networks. These features, which go under the name of self-organizing networks (SON), include self-configuration and self-optimization. LTE will be deployed in parallel with simplified, IP-based core and transport networks that are easier to build and maintain.

LTE base stations

RAN performance and, in particular, base station performance have a large impact on capital and operating expenditures (CAPEX/OPEX) when deploying and operating a radio network. Our new RBS 6000 series features an extremely powerful base station architecture. It includes the Digital Unit for LTE (DUL), with a multi-core architecture as well as the Multi-Standard Radio (MSR) that supports LTE as well as GSM and WCDMA in the same radio unit. RBS 6000 thus provides a future-proof investment that is equally valid when the modules are used in RBS 2000 and RBS 3000.

Ericsson takes LTE field testing to new heights

Image

Ericsson proves the capabilities of its LTE/EPC system in a new and innovative way. Two engineers get into the back seat of a small jet plane to test a network while flying at low altitude in speeds of up to 700 kilometers per hour. The result? Have a look!
