Coverage of large office buildings or manufacturing plants using a full mesh network often becomes an extremely demanding task. In most of these cases, the sensors installed are concentrated in small areas where usually wireless communication is challenged by various obstacles or even distance. In such cases the Sub GHz band and especially the 169 MHz ISM band proves to be a useful tool to resolve connectivity issues in a wireless manner and avoid high installation costs. The 6 wMbus mode N channels allow more flexibility on the channel selection. The low bit rate bandwidth and the regulatory directives that do not allow channel utilization 10 in this band are also covered by Meazon Zi-Gate.
