SmarTrunk Systems, Inc.
SmarTrunk II has two advantages in this environment. First, SmarTrunk
II is more tolerant of conventional and co-channel users than LTR, as
discussed above. Secondly, SmarTrunk II is an “overlay” system, which
means that existing repeaters and most popular conventional radios
can be converted to SmarTrunk II on a retrofit basis (see Appendix A).
By contrast, the LTR system uses dedicated LTR radios, so the system
operator is forced to scrap his existing conventional equipment and
make a substantial new investment in radios.
Which System Is Best for You?
Both SmarTrunk II and LTR have their advantages and disadvantages.
The choice of system depends largely on the features and type of
service to be offered and the availability of clear (exclusive) channels.
In general, LTR may be preferable for a new shared system offering
dispatch-only service on exclusive channels with no conventional
users. On the other hand, SmarTrunk II may be preferable for systems
offering a mix of private calling, group calling, and telephone
interconnect service on non-exclusive channels. In this respect,
SmarTrunk II is ideally suited for private “campus” systems which are
typically interconnected to an office PABX; for shared public systems in
rural areas that can legally offer telephone interconnect service; for
systems with extensive private calling requirements; and for existing
conventional systems that are being gradually converted to trunked
operation.
