By comparison, Codecs such as MP3 don’t have to
encode audio in real time so they achieve better
compression and audio quality.
Unfortunately, current digital radio protocols and
standards do not specify widely-implemented or freely-available Codecs (even those that use RTP and SIP).
One solution is to continue to use gateways that are
designed to transmit the added digital radio data
and functionality. This approach provides additional
• radios with Point-to-Point protocols can be shared
amongst a number of operator positions,
• only one vocoder (located in the gateway) is
required, shared amongst a number of users,
• radios can be accessed simultaneously by different
• gateways provide flexibility to change protocols
to meet future demands.
The above is an extract from the Omnitronics White Paper
“Understanding RoIP Networks” which you can access here.
This white paper delves further into the above
considerations and also discusses and compares the range
of IP Connectivity methods organizations can choose from
to best suit their needs.
