Analysis of the 2.6 GHz Spectrum Auction in Belgium

The 2.6 GHz spectrum auction in Belgium closed yesterday after it netted a total of €77.8 million for a total of 155 MHz. Although the media reported the outcome as being low, I think the price is representative for this band at 4.6 euro cents per MHz-PoP. This is more so the case as the license is valid for 15 years while in other countries the licenses are for period of up to 20 years.

Mobile Data Traffic Forecasts: A Comparative View

When it comes to planning radio access networks, mobile traffic data forecast become very important: Operators need to properly size their networks, and the ecosystem needs to predict potential bottlenecks and come up with creative solutions. The granddaddy of all traffic forecast, Cisco’s VNI was used to argue the need for more spectrum. Hence, a lot ride on these forecasts and anyone who has been to industry events notes how often these forecasts are used to make a point of the impending “capacity crunch.” Ericsson recently released a white paper on their data forecast, so I wanted to compare it with other data available on the market.

VoLTE in LTE Migration Strategies

Voice over LTEAt a recent conference I attended, a strategy executive at Deutsche Telekom stated that they would turn off the 3G network before turning off 2G GSM as the migration to LTE evolves. Sounds bizarre? Not really, it makes a lot of technical sense. One reason to come to this decision is the nature of the LTE architecture and the way LTE handles voice traffic. As a full-packet network, LTE is fundamentally different from the full circuit-switched GSM and hybrid circuit and packet-switched 3G networks which include today’s data workhorse HSPA+. In LTE, voice is just another application, albeit one with specific parameters and requirements. Therefore, voice is packetized and classified according to a certain Quality of Service level (QoS) to maintain important parameters such as latency and jitter. This is essentially what Voice over LTE (VoLTE) is. Read more of this post
