Single Carrier BTS
The single carrier BTS is offered in all four (4) standard GSM Bands. As with most
single carrier base stations this one offers 8 total timeslots (7 1 control). Voice,
CSD and General Packet Radio Service (GPRS) are supported. The LTGSM can
support up to 20 single carrier BTSs.
CAUTION – The single carrier BTS used in the LTGSM system was designed as
an indoor base station. As such, the receiver on the BTS is not as efficient as
those found in commercial grade outdoor base stations. This means that the
LTGSM system will be more susceptible to interference and may not provide a
balanced link to and from the GSM handset. TLC has taken steps to resolve
some of the complications associated with the BTS, but can not guarantee
optimal service during its use.
Note – The standard GSM bands are 850 MHz, 900 MHz, 1800 MHz and 1900
MHz.
