huh
thats funny

My milestone on XT looses signal down by the waitangi rd turnoff at the bottom of the hill, and it returns by the time you pass the firestation and has coverage all through the village.

I've found today that if I move 1-2 meters in any direction while talking outside the dairy it drops on XT :(... So I am now on Cafenet since I have an old account with enough prepaid data.. Since Vodafone GPRS is just not useable at all.

raytaylor: Hi all
I was out at Waimarama the other day and saw Vodafone had a cell site out there with some fancy looking gear up on a hill nearby.

What was interesting about this cell site was i didnt see any microwave backhaul. There was a sector antenna pointing down to the village and beach, an omnidirectional which i assume is for 2g coverage on both sides of the hill for the beach and few houses behind it. But no microwave.

I think the sector antenna is AirNet. There are a few houses in Waimarama who have AirNet including the Dairy who offers CafeNet (using it now) who have a square high DB antenna mounted on their houses pointing up the hill.

I have also been doing speed tests and I get excellent 3G Extended coverage on 900Mhz (in fact better than 2G strangely enough) with my Mother in law's Nokia C3-01 phone which she just purchased. I get full bars on 3G, but only 2-3 when I go GSM only.

Going to try teathering it to my PC later and running a speedtest when she lets me play with it.

Thats a thought.
I have been looking for the airnet AP for a couple of years now and could never figure out where it was. But your right, the sector could be airnet.

I have seen the airnet link on top of the dairy and a couple of houses and yea it does make sense as they are pointing in that direction.

I didnt think of that because i saw on the napier and hastings telephone exchanges they have their logo on their microwave backhauls but no logos up at the waimarama cell site. They also dont have any logos on their microwave array up Mt Threave so that makes sense.

The RSM Database for AirNet (Customer ID 501458) has some interesting entries.. but nothing for the Vodafone Waimarama Beach site (Location ID 30166) where Vodafone is the only entry. So Airnet must be running high-gain WIFI (either B/G/N in the 2.4 or A/N in the 5Ghz) in the un-licensed spectrum.

Airnet usually use 5.2ghz wasp tells me or its maori managed spectrum like 2deg.
Also vodafone have managment rights on their cellular spectrum so you generally only see their licenced backhauls on the RSM website.
If telecom run the fibre then there would be no licenced backhaul for the waimarama site.

Even if it's Maori spectrum it still needs to be registered with RSM. Only the unmanaged frequencies such as the wifi frequencies is what you can run without needing to register with RSM (or just pretend you don't need to register the frequency and hope not to get snapped)

Erm, you're wrong there. Every Telecom, Vodafone and 2Deg site is registered with their transmission area. Since how else could I list all the Mobile Cell Sites in my KMLs ;)

Check out Location ID 30166 in RSM (paste the number in the bottom box saying "Location ID" then click the "Search" button up the top), It's the Vodafone Waimarama site. It has fibre backhaul and thus no microwave but it does list the 952Mhz and the reception area that Vodafone are allowed to transmit in and their dBW EIRP strength.

huh. Ive never come across those. learn something new every day.
I always thought that if its under managment rights, then the right owner can use their own managment system rather than the RSM's database.

There is still the potential for interference, even for spectrum under management rights.

Agreed... Think of the arguments between Vodafone at Telecom just prior to the XT launch. But if you want to transmit anything in NZ over the airwaves it needs to be registered with MED RSM. Unless it's part of the un-managed frequency ranges such as what WIFI and cordless phones etc run over.
