Loftus:
If I was on the board of TNZ I would be regretting the loss of that 5 MHz of AMPS spectrum - that would have made a future 850UMTS deployment much easier.


I missed that, when did Telecom loose 5Mhz of AMPS spectrum?
With the Gov Tenders for Spectrum this year, dosent Telecom have the option of getting more in the "850" range?

inquisitor: So VF's UMTS900 network is a huge threat to Telecom, that forces them to deploy UMTS850 very soon.


I think that's a bit of an over-statement, as TNZ's existing CDMA/EVDO network should provide useful competion in terms of range and performance, compared to VF's new UMTS900 overlay. If nothing else it gives TNZ breathing space to execute a clear long term strategy.

Now that it's possible to deploy advanced networks in the "old" GSM900 & AMPS850 bands, I think it significantly increases the value of those bands for a network operator - especially when you factor in the increased range available per network site.

With UMTS/HSDPA going to 7.2 mbps down and 2mbps up (shortly)

They could see it as a threat but I guess best to ask someone in Telecom

The CDMA network performs well and will meet most customers needs for years to come

Seeing how most users simply don't use 7.2 mbps on their DSL yet alone the mobile network the speed upgrade is more of a marketing job, as the Node B's (3G cell sites) can still only handle about 15-20 HSDPA codes. the speed upgrade simply means that a single user can be allocated more codes therefore increasing their bandwidth, with the max for HSDPA of 14.4mbps requiring 15 codes. this means that you can simply saturate a cell quicker with the new technology and Vodafone already have issues with cell loading and backhaul data bandwidth back to their internet core anyway.

overall result is probably going to be on average same or even slower speeds on mobile broadband unless they can fix the loading and bandwidth issues.

In Vodafone's defence however they are rolling out a lot of new 3G sites at present. There is a huge network build occuring in Wellington at present with at least 5 or 6 sites that I saw the other day all under construction covering the road from Pt Howard to Eastbourne. Their backhaul is the problem however, hopefully it's something they're putting a few $$ into.

TNZ haven't lost the spectrum yet, but the decision has been made by Cabinet to require TNZ to sell at least 5Mhz to a "new entrant" as a condition of the upcoming management rights renewal. (M.E.D. link)

The renewal offer expires on the 9th May, so I'd expect to hear from TNZ's soon.

There're already operational networks supporting HSDPA with 14.4 MBit/s and Vodafone have shown a HSDPA-setup running with 28.8 MBit/s at CeBIT.
Being a major cost factor on mobile networks backhaul capacity is becoming an issue with the acceleration of the air interface. One solution, which T-Mobile has chosen, is to connect NodeBs through ADSL2+ to the core network. Another interesting thing, that will increase network capacity while cutting costs, are femto cells, through which subscribers will cover not only their house, but their neighbours', too. Especially in urban areas femto cells could discharge the big NodeBs.
However in the short term there's nothing left but upgrading existing micro wave or wire connections to the backhaul.
