This week I been in the Mobile World Congress in Barcelona.
A lot of words were written about the show, by people with much more knowledge and better writing skills.
The second trend is LTE, it’s enough to see some of the press releases from Verizon, Ericsson and Alcatel-Lucent to understand that the industry is aligning behind the technology, and in 2010 we are expected to see the first roll outs.
LTE represent a all new set of Diameter interfaces, with brand new networks that are using (by the standard) more than 45 Diameter interfaces, Diameter is everywhere and actually not limited to the core anymore, it is moving out to the edges, up to the last mile – those Diameter interfaces are not out there yet – so what will NEP’s do – I guess as always – build their own semi standard interfaces – and will continue to sweat on interoperability and lock the operators
The last trend is the Cloud – some heavyweights such as IBM, are pushing it, and they see it taking over the telecom world.
Financially it makes sense, mainly with MVNO’s and small operators but also with the Tier-1’s that don’t want to spend billions on OPEX and CAPEX.
I think one of the main issues that I can see from that level is that there are going to be huge interoperability issues, and the datacenters will need to have Diameter Gateways in the entrance to the cloud to make sure the information can be spread inside the cloud with no vendor and standard lock-in.
There are a few more things that changed this year, such as UMA – one of the big trends of the last few years almost disappeared, and it seems that Mobile WiMax might be going in the same route, unless something drastic will change, most of the people I met weren’t’ optimistic on its future.
That it, next time I will try to dig in Diameter and LTE, what is new, and some of the challenges.
