Variable message signs are generally connected with GPRS connections providing low speed connections for the signs. Mesh4G provides two additional options in addition to the GPRS option:
1. To move to 3G. This allows VMS signs to have two routes back: one over GPRS and another over the separate 3G network. Revenue costs are similar.
2. Use Mesh4G wireless nodes where the network is close to other Mesh nodes. It is also possible to create small clusters of 2 or more VMS signs that use 3G for a backhaul whilst being connected together with Mesh4G radios.
With higher speed connections it is possible to connect CCTV, Sensors and ANPR.
