RAN Sharing

Study on 3GPP RAN sharing enhancements

A recent study from 3GPP looks at how operators can share common LTE radio resources, according to identified RAN sharing scenarios, whether as a shared deployment or as a leased asset.

The first version of the Technical Report covers the E-UTRAN, but a revised edition is set to follow shortly -  broadening the coverage to UTRAN and GERAN so that 2G, 3G, and 4G networks are covered.

Deploying Public Safety LTE

April 1, 2014, Analysis from

New data, from James Bennett of SNS Research, suggests that by 2020 the installed base of private public-safety LTE eNodeB units will approach 155,000, serving an estimated 4 million professional users worldwide.

The success of LTE, combined with the limited potential – for data - of existing private mobile radio systems, has led public-safety organizations to consider LTE as the de-facto future standard for mobile broadband. The article also points out that large LTE deployments can save up to 40 percent in the total cost of ownership, by opting for a public-private partnership, using a mix of private and commercial spectrum.

3GPP RAN: Rel-12 and beyond

Dino Flore, 3GPP RAN Chairman, February 2014

3GPP RAN (Radio Access Networks) has started a new innovation cycle which will be shaping next generation cellular systems. The work spans a variety of new technology areas, which are briefly described in this article. 

LTE: capacity and cell-edge performance improvements

In order to meet the growing mobile data demand, 3GPP is looking at a variety of technologies that will improve network capacity and cell edge performance of LTE networks. The key focus here is on network hyper-densification, as it is generally agreed that this approach can deliver significant capacity gains.

fig013GPP started working on Small Cells (low-power nodes) in Release 8, with focus on residential or enterprise use for a Closed Subscriber Group of users. But with Release 12 it is taking the use of Small Cells and network densification to a whole new level in order to achieve the desired capacity gains. This includes the development of a number of radio and protocol solutions that are aimed at improving spectral efficiency and operation when the density of small cells increases.
