Years 9 live=)
I've been using homemade antennas point DWL-2100AP, then moved on to purchase yagi, and then on ready-made sets of access points, street performance Ubiquiti nanobridge m2. I recommend just the like to take a few or a couple of mikrotik.
Did Called the operator, leave the application for connection at the house where I wanted to put the antenna on the address of the last+N, where N is an arbitrary number, but not too big =) Previously agreed with the Chairman of the house (gave on a paw) on the installation of the antenna (to sit down to a blank space on the mast is not lowered).
Because the Antenna and the access point is one thing, but still powered through the twisted pair, then the installation will not take much time. Even in the moment of connection, but better (with laptop olusturulan on the signal level, preferably with two sides. On the roof you can probably find the socket or the bulb for a trial run)
Then put your cable (shielded, 8 core - FTP) directly to the box the right of the operator.
When the installer arrives - show him the cable and PoE adapter. Put it straight into the bin operator and sign just in case - "Employee" =) (Later I really became a associate in the provider) For tractability can also give paw.
On the other side of radiobridge - wire needs to be connected to the device whose Mac address will have to see and register at provider settings, respectively, should be introduced. And that's all.
Each step has its intricacies that it is better to plan in advance and work out.
For example to pre-configure each other points, save the configuration. Try different frequencies, and it is better on a custom =) and not remove the power to the max and Vice versa it is better to underestimate!
