What's a network operator without a network?

It seems like a stupid question. I mean, if a network operator doesn't actually operate their own network, what's the point?

News today that Vodafone and O2 may be about to strike a network sharing deal means that there could in effect only be two mobile networks in the UK.

Such is the pressure on margins - and the cost of building and maintaining a network - the network sharing seems to be an innevitable endgame in markets such as the UK. With new spectrum auctions looming for '4G' services and the cost of LTE network build-out already causing nervousness among mobile operators, it seems the obvious thing to do.

But what does it all mean? One can't help thinking that by surrendering even a little control over the network, the operators are simultaneously surrendering some control over their own destinies. Will innovation run at the same pace? Will we end up stuck with a lowest common denominator network?

With evidence from people like Actix* suggesting that operators can slash OPEX by up to 30% through automating network status management and, ultimately, moving towards a self-optimising network, are things really so bad that operators have no alternative but to share networks?

OK, as in life, there may well be degrees of sharing (what's yours is mine, what's mine is mine etc.), but for network equipment vendors and landlords of tall buildings currently seeing a base station as their best bet for a tenant in the current economic climate, it's probably not the best of news.

Let it Snow!

A bit of inclement weather and the country grinds to a halt! I mean, seriously, the worst snow in 18 years and suddenly the whole national infrastructure falls over.

And I mean the WHOLE national infrastructure ... even the mobile phone network!

OK, so I expect the websites of the rail companies to struggle with the traffic (I mean, if they can't run a train network, why should their IT network be any different), but getting a "network busy" signal on my mobile when I tried to make a call? Well, that's just not on.

It seems ludicrous that the mobile phone network can't cope with spikes in traffic, but then when you consider the complexity of planning a radio network and the fact that for many operators the management of it is still not automated and maybe it's not a surprise. If the network engineers can't get into work, how can they fix it when it starts to creak under the strain?

At the end of last year I picked 'Self-Optimising Networks' as a theme for 2009, and you can see why. If an operator had SON, then as soon as a cell starts to creak, neighbouring cells can turn-up their power and take some of the strain. Similarly, the network could prioritise certain traffic to ensure that voice calls still go through. Actix* is one of the companies that is leading the charge in SON and automated Network Status Management (NSM) ... and you have to say, any more snow and they'll be quids in!
