UK 4G Spectrum Auction Concludes – A Brief Analysis

4G Spectrum AuctionThe long-awaited 800 MHz and 2600 MHz UK auction concluded today with a total of £2.34 billion, or $3.63 billion (Ofcom set reserve price at £1.3 billion). The winners of 60 MHz of digital dividend spectrum in 800 MHz band include EE, 3G, O2 and Vodafone. In the 2.6 GHz band, Vodafone, EE and BT divided 185 MHz among them with the lion share going to EE who got 75 MHz of paired spectrum. The winners will participate in a second round to decide on the exact frequency allocations. Read more of this post

The Hype and Reality of Small Cells Performance

Heterogeneous networks (HetNets) consist of large (macro) cells with high transmit power (typically 5 W – 40 W) and small cells with low transmit power (typically 100 mW – 2 W). The small cells are distributed beneath the large cells and can run on the same frequency as the large cell (co-channel), or on a different frequency. As an evolution of the cellular architecture, HetNets and small cells have gained much attention as a technique to increase mobile network capacity and are today one of the hot topics in the wireless industry. Many of the initial deployments of small cells are of the co-channel type. Standards such as LTE have focused on incorporating techniques to improve the performance of co-channel deployments in earlier releases of the technology standard leaving the handling of multi-frequency deployment type to later releases. In all, operators today have multiple options of small cell deployment scenarios, operational techniques and technology roadmaps to choose from. Read more of this post

More and More Small Cells, But Where’s the Gain?

Small Cell StrategySmall cells are meant as a solution to address the explosive growth in mobile data services, right? Well, the answer is: it depends! They can be a solution under certain conditions, but not always. Yes, there could be situations where small cells add little if any gain. In fact, more than one operator mentioned to me little or even no gain in overall capacity increase by their small cell pilot projects. So what’s happening, and why can we run into situations where small cells don’t deliver on their promise? Read more of this post
