Stefan Zehle, CEO at Coleago Consulting, discusses the current spectrum auction landscape in Europe.

Eurocomms.com: You recently wrote a report on the outcomes of the 4G spectrum auctions in Europe – what did you find out?

Stefan Zehle: We saw vastly different prices in the 800MHz spectrum as a result of a number of different factors. Supply and demand was the most important, so we saw very high prices where the number of bidders exceeded the available spectrum. In Germany, for example, four bidders competed for 2x30MHz of 800MHz spectrum and prices were driven up until the weakest bidders decided to withdraw. On average in Europe, prices paid for 800MHz spectrum have been 15 times higher than for 2.6GHz spectrum due to the better propagation characteristics of the 800Mhz spectrum.

Eurocomms.com: With 4G auctions ongoing across Europe, what is your assessment of where the continent stands currently compared to the rest of the world?

Part of the reason is that Europe was so advanced in 3G – we had HSPA+, for example, which users have found acceptable whereas in the US data networks just weren’t fast enough.The US also has Apple, whose services and popularity accelerated the adoption of LTE.

Rupert Bent, legal director, and Jon Fell, partner, at international law firm Pinsent Masons LLP discuss all things patents.

2011 was a year when patent wars returned to the headlines with a vengeance. Why do you think this was?

There are two main reasons. Firstly, it is vital to bear in mind the current economic environment. In a global recession companies want to safeguard market share and protecting your new innovations legally from being copied is a crucial part of this.

Mike Flanagan discusses Arieso’s second annual study of smartphone data use (including dongles and tablets), which analysed over 1.1 million subscribers in Europe over a 24-hour period. The survey used the iPhone 3G as a benchmark.

Eurocomms.com: The survey showed that iPhone 4S users consume twice as much data as iPhone 4 users. I thought there was minimal difference between the two models so why has data consumption doubled?

Mike Flanagan: I thought the same but there are two key differences that account for the growth: first, the 4S uses the cloud so users are constantly synching with services such as iTunes that increase the number of data calls; second, the 4S has voice recognition software Siri which has made it much easier for users to perform tasks on their smartphone that they might traditionally have used a computer for.

Ian Foddering: One of the single most important things is download and upload speeds as well as latencies. These are vital measures to assess network capabilities of cloud readiness and should one of the big focuses for operators.
