Emergency Services Command & Control Vehicle Connectivity


An Emergency service has a fleet of command and control vehicles that are deployed for major incidents.
The command and control vehicle acts as a central communications hub (Radio / VoIP / Video) for the local staff and enables cross service communication via a secure VPN to the services Datacenter.


The intelligent use of multiple cellular and satellite internet connections depending on the vehicle’s location (and cellular availability). With the cellular WAN connections being prioritised over the more expensive satellite link. This is to reduce the use of the satellite internet connectivity where bandwidth costs are high in comparison to cellular.
WiFi network coverage for multiple LAN side devices.
Secure VPN connectivity back to the emergency service datacenter using whatever WAN connectivity is available, with the option to bond multiple cellular links to increase the total available bandwidth.
The solution must allow for High Definition video transmission back from the vehicle to headquarters to allow commanding officers to evaluate the situation at the incident.
Support for reliable Radio Over IP (RoIP) and VoIP connectivity between the vehicle and the core Radio Access Network (RAN) / VoIp Server.
Enough bandwidth to allow for rapid transmission of large files such as building plans, maps, and digital images.
Support for dedicated public services private LTE radio network, with future expansion possible to use point to point microwave links.

Recommended Solution:

To allow for as much versatility as possible (including the use of restricted specialist cellular radio modems) a balance 580 is installed in the command vehicle as the core network router.
Cellular Modems (such as the BR1) are connected to the WAN ports of the 580 along with the VSAT internet connection.
WAN priority is set to achieve lowest cost routing based on WAN availability (Satellite is only used if there is no cellular coverage).
The Balance 580 has directly connected PC’s and servers on is LAN that support core activities (such as Radio Over IP dispatcher equipment) as well as an AP300 access point for smart device connectivity.
The Balance 580 acts as an AP controller for the deployed APs, providing centralised management and configuration of the deployed wifi network.
User Group bandwidth management and application QoS is used to guarantee and reserve bandwidth for core business requirements.
The remote Balance 580 creates a secure encrypted VPN connection to the balance 1350 in the datacenter using SpeedFusion.
SpeedFusion VPN supports bandwidth aggregation, packet level failover and WAN smoothing to provide the highest possible bandwidth, with the most reliable connectivity possible over the connected WAN links.

Additional Notes:

There is a spare WAN port available on the Balance 580 in this design to allow for the deployment of point to point microwave links if desired.
Additional AP300 Access Points can be added to the network to extend its coverage, as well as externally mountable AP One Flex access points that have software selectable directional or omni directional antennas - allowing for extended wifi coverage outside of the vehicle .
The BR1s used on the WAN of the B580 can also connect to any available WiFi Hotspot in the vicinity when available as an alternative to cellular.
The Balance 1350 can support upto 800 remote vehicles (dependent on concurrent bandwidth requirements).

Devices Deployed: Balance 580, Balance 1350, BR1 LTE, AP300.

Why MAX-HD4 didn’t use in the vehicle?

To allow for the use of specialist restricted public safety data radios. These present on ethernet, so a balance 580 was used so that up to four of them could be combined (along with the VSAT connection).
