5 Replacing or installing new TRX units
A MetroSite BTS can be upgraded to EDGE by replacing 1W or 5W GSM TRX
units with 5W GSM/EDGE units.
Additional TRXs can also be added to a single BTS (up to four TRXs) in order to
increase the BTS’s capacity or to add EDGE capability.
A 5W GSM/EDGE TRX can be commissioned to operate on GSM or
GSM/EDGE transmission.
It is possible for a BTS to contain a mixture of 5W GSM and 5W GSM/EDGE
TRX units.
Figure 9 shows the slot order of TRX units in a MetroSite BTS. TRX 1 is always
the master TRX.
