||
3 | |||
4 | This page describes how ot configure + set up an ip.access nanoBTS to use it in conjunction with OpenBSC (i.e. [osmo-nitb] or [osmo-bsc]). |
||
5 | |||
6 | Please note once again that the Osmocom project has no affiliation and no contact with ip.access. All information here is presented |
||
7 | based on our own experience only. If you have official documentation by the manufacturer, you should probably consult that instead |
||
8 | of using this wiki page. |
||
9 | |||
10 | == Physical set-up == |
||
11 | |||
12 | === Power supply === |
||
13 | The nanoBTS uses PoE (Power-over-Ethernet). It does not have any other power connector, so you will have to use a PoE-Injector (aka ''mid-span'') |
||
14 | or a PoE capable switch (like the Netgear FS-108P for a small desktop switch). |
||
15 | |||
16 | Please note the power demand of the nanoBTS is quite high for a PoE powered device. You may not be able to use all the PoE ports of your switch |
||
17 | for nanoBTSs. Check with your switch vendor and/or ip.access. |
||
18 | |||
19 | On first sight, there appear to be three RJ-45 jacks on the nanoBTS. However, two of them are actually RJ-69 (10-pin) and only used in stacking |
||
20 | configurations (see [nanoBTS_multiTRX] for details). This leaves only 1 real RJ-45 marked '''LAN/48VDC''', and that's where you connect your |
||
21 | powered Ethernet. |
||
22 | |||
23 | === Antennas === |
||
24 | |||
25 | There are four SMA connectors, one on each corner. |
||
26 | * RX (receive antenna for uplink) |
||
27 | * TX (transmit antenna for downlink) |
||
28 | * NWL (network listen, a special mode where the BTS behaves like a MS to receive other BTSs) |
||
29 | * AUX (once again only used for stacking, see [nanoBTS_multiTRX]) |
||
30 | |||
31 | RX and TX should each be connected to an antenna, either the small factory-supplied antennas, or some larger antenna or even an RF distribution |
||
32 | system or an external LNA + PA + Duplexer kit. |
||
33 | |||
34 | '''Do not power up the device without a TX antenna''' |
||
