So... how many tags will this node have, once you have tagged all of its components?
From [1 <https://en.wikipedia.org/wiki/Base_transceiver_station>]:
> A *BTS *is usually *composed of*:
>
> Transceiver (TRX)
> Provides transmission and reception of signals. It also does sending and reception of signals to and from higher network entities (like the base station controller <https://en.wikipedia.org/wiki/Base_station_controller> in mobile telephony).
> Power amplifier (PA)
> Amplifies the signal from TRX for transmission through antenna; may be integrated with TRX.
> Combiner
> Combines feeds from several TRXs so that they could be sent out through a single antenna. Allows for a reduction in the number of antenna used.
> Multiplexer
> For separating sending and receiving signals to/from antenna. Does sending and receiving signals through the same antenna ports (cables to antenna).
> Antenna
> This is the structure that the BTS lies underneath; it can be installed as it is or disguised in some way (Concealed cell sites <https://en.wikipedia.org/w/index.php?title=Concealed_cell_sites&action=edit&redlink=1>).
> Alarm extension system
> Collects working status alarms of various units in the BTS and extends them to operations and maintenance (O&M) monitoring stations.
> Control function
> Controls and manages the various units of BTS, including any software. On-the-spot configurations, status changes, software upgrades, etc. are done through the control function.
> Baseband receiver unit (BBxx)
> Frequency hopping, signal DSP.

Mapping each component (/yes, the antenna too.../) separatly doesn't make much sense to me...
