EBTS Site Description
iDEN (integrated Digital Enhanced Network) is a digital communications
system which combines the capabilities of a standard analog dispatch
system with that of a cellular interconnect system. iDEN uses an advanced
proprietary modulation technology consisting of a speech compression
scheme enabling three or six communication paths over a single 25 kHz rf
channel.
iDEN allows users with mobile and portable subscriber units to
communicate with one another over the Public Switched Telephone
Network (PSTN) using the rf system as the medium. The rf system consists
of strategically located Enhanced Base Transceiver Systems (EBTS) which
are linked to the Mobile Switching Office (MSO). The MSO in turn provides
the connectivity to the PSTN. Refer to Figure 2-1.
