Server PC requirements

TRBOnet can handle up to 4 simultaneous voice sessions per one CPU Thread.
For example, to handle 48 simultaneous calls you will require 48/4 = 12 CPU threads.
Usually in the case of a large system with 24+ voice sessions, the requirements are:
1.      CPU – calculated by the formula above
2.      RAM (Memory):   16 GB for the case where there is less than 50 channels,
                                      32 GB for the case where there is 50+ voice sessions
                                      OR
                                      32 GB for the case where virtual machines are used on the physical server
3.      2xHDD 500GB in RAID 1 – for windows installation
4.      2xHDD 1TB in RAID 1 – for audio storage & database archives

An example of MSSQL Server Database size calculation

24 channels busy system with 700 radios generates:
Database – 3 GB per month (a large amount of GPS data)
For audio recordings storage, 1 min = 1 Mb.

You may use Microsoft SQL Express (it is free of charge) but it has a 10 GB Database size limit. If calculations result in a data size that is more than 10 GB and all data needs to be immediately accessible, then consider using a full (non-Express) version of the SQL server.

IP Backend Network Performance Requirements

Before planning any IP connected MOTOTRBO systems please check System Planner (chapter “4.9.3. Considerations for the Back-End Network in IP Site Connect Mode”)
  • Delay/Latency is characterized as the amount of time it takes for voice to leave the source repeater and reach the destination repeater. Delay should be less than 60 ms. It can be up to 90 ms, but requires changes in CPS for subscriber units and for repeaters..
  • Jitter is the variation of packet inter-arrival time. It should be less than 60 ms.
  • Packet Loss. In the case of voice, the ongoing call ends if six consecutive packets do not arrive within 60 ms. of their expected arrival time. In the case of data, the repeater waits for the expected number of packets (as per the data header) before ending the call.
  • Bandwidth. Refer to System Planner for bandwidth calculations, but roughly, it requires 96 Kbps for each repeater connection and should be summarized for all repeaters.
If the IP backend network does not satisfy MOTOTRBO requirements, it will degrade audio quality significantly to a point where there could be dropped voice calls.

TRBOnet Enterprise Network Performance Requirements (TRBOnet 5.2.5.1427)

Note. All delay values are to be considered as "round-trip delay time” (RTD).
It should be considered that every hop (that occurs at the process of network packets delivery) also takes 1-2 ms.

1. TRBOnet Server – Dispatch Console connection

1.1. IP Connection Network performance requirements:

Delay < 2900 ms
Jitter < 50 ms
Packet loss < 2%


1.2. From Dispatch console to Server:

Bandwidth calculations are based on the number of Dispatch Consoles.
Each connection requires 128 Kbps for voice and 66 Kbps for data


1.3. From server to dispatch console:

a) Voice traffic:

Bandwidth calculations are based on the number of Voice sessions and the type of Codec used:
BandwidthVoice = X * N
Where X is the number of connected systems (simultaneous voice sessions) to the server
N is the bit rate for the type of Codec used.

CODEC Bit Rate (Kbps)
G.711 µ-Law/8000 64
G.711 A-Law/8000 64
G.729/8000 8
SPEEX/8000 8
SPEEX/16000 16
AMR/8000 4.75-12.2
AMR/16000 6.60-23.85
AMBE/8000 2-9.6
OPUS/8000 6-128
OPUS/16000 6-128
PCM/8000 128
PCM/16000 256
PCM/22050 352
PCM/44100 705
NOTE: for LCP/Cap+ systems, each audio path added at the server is considered as one system.

b) Data traffic:

Bandwidth calculations are based on the number of Subscriber Units (radios)
The requirement is 64 Kbps for 300 Subscriber Units and 128 Kbps for 600 Subscriber Units.
BandwidthData = (SU / 300) * 64 Kbps
Where SU is the number of radios in the system.

Final Bandwidth formula = (Traffic for Voice + Traffic for Data) * Number of Dispatch Consoles

2. TRBOnet Server in fail-operational capability mode (Redundancy mode)

Delay < 1500 ms
Jitter < 100 ms
Packet loss < 2%

Bandwidth calculations are based on the number of systems connected to the Remote Agent/Server and the type of Codec used (See above).
Bandwidth = X * (N + Data)
Where X is the number of systems connected to the remote agent/server (simultaneous voice sessions) 
N is the bit rate for the type of Codec used.
Data is 50 Kbps average

3. TRBOnet Server – Remote Server and Remote Agent

Delay < 2900 ms
Jitter < 50 ms
Packet loss < 2%

4. TRBOnet Server – Friendly Server

Bandwidth calculations are based on the number of dispatcher connections.
Each connection requires 128 Kbps for voice and approx. 50 Kbps for data;
For example, for 5 dispatchers, Bandwidth = 5 * (128+50) = 5 * 178 Kbps

Swift Agent <-> TRBOnet Enterprise Network Performance Requirements

Swift Agent A001/A002
Maximum latency < 300 ms
Jitter < 60 ms
Packet loss < 1%
Bandwidth 160 Kbps which are used exclusively by Swift Agent

Swift Agent A100/A200
Delay < 1800 ms
Jitter < 60 ms
Packet loss < 2%

Mobile Client <-> TRBOnet Enterprise 5.2.5 Network Performance Requirements:

Delay < 200 ms
Jitter < 100 ms
Packet loss < 2%
Reordering < 2% (not being summarized with the packet loss requirement, both parameters should be < 2%)

Bandwidth = N*5 +- 5Kbps.
N is the bit rate for the type of Codec used.

Mobile Client <-> TRBOnet Enterprise 5.3.5 or higher Network Performance Requirements:

Delay < 800 ms
Jitter < 100 ms
Packet loss < 3%
