WIMAX, LTE, Fixed, Mobile

I had an interesting insight today. In the constant debate between Wimax and LTE, realised one differentiating factor today - when it comes to developed market installations, its quite possible that WiMAX will be supported by fixed line operators and LTE will be the natural progression path for mobile operators. Fixed operators can use it for the last mile connectivity, last mile backhaul etc. For mobile operators, it would be the technology of choice only in greenfield implementations which are relatively fewer. For example, remote India wherever long distance coverage is needed - there is no fixed network, no mobile network - go WiMAX. (The fixed flavour of Wimax is 802.16d while the mobile version is 802.16e.)
I know there's Sprint Clearwire and their rollouts in Portland. But if you look at the UK market, the hype around the spectrum auction for WiMAX later this year is set to be utilised to the utmost by BT. No mobile presence (T-Mobile and 3 anyone?), lack of WiFi presence as well after the split with The Cloud, hot now cold now position as an MVNO - all factors that speak in favour of a WiMAX launch. But will the financials and market conditions allow it? The markets haven't been too kind to BT of late - their pension liabilities as well as poor performance in Global Services. But that may be made up with positive news from Ofcom on more flexibility for the openreach licensing to competitors.
But coming back to WiMAX and LTE - look at France. They had their auction launch almost two years ago with players like SFR, Neuf (then), TDF, Illiad/Free making the investments in spectrum. However, it seems only 15% of the anticipated installations are live. The failure - the focus on WiMAX replacing fixed connenctivity in remote areas rather than better and faster mobile connections. No - business models focused only on rural areas cant possibly be the answer.
