I have just got 4G RBI and thought that I had a reasonably simple installation with 4.5k line of sight to a local cell tower. I purchased an external antenna (discussed here http://www.geekzone.co.nz/forums.asp?forumid=49&topicid=205138) and am in the process of trying different locations and directions to tune the signal.
The best signal I have been able to get so far is:
However the PCI (Cell ID) changes between two values and this dramatically affected speed tests and connectivity. Attempting to detune to get the 'best' tower sometimes picks up a third tower!
So it looks like I can 'see' 3 towers and the performance and reliability is dramatically different depending on which one I connect to. 2 towers are very close in terms of direction, a couple of degrees at most.
How can I find out which towers the PCIs identify so that I can know which one to aim for?
The PCI values are (Vodafone) 253, 256 and 258? (I suspect these are ARARIMU, HUNUA and KAIAUA but don't know which is which or how to find out)
And how can I make sure I only connect to a specific tower?
The antenna I am using is one of these: https://www.gowifi.co.nz/antennas-700-900-directional/ant-205.html - Are there more directional antenna so that I can aim more precisely? or are there less powerful antenna so that I connect to the closest site (which I think is what I want)
My main concern is that weather could tuning so that no matter what I do i might get shunted to another tower if it rains.
(Hoping that I can get this resolved otherwise I am stuck with sub 1mbps adsl that stops working when it rains)
