Transmission range is defined as the maximum distance a signal is sent by a transceiver and can be reached and interpreted at the receiver. Given that industrial environment is RF hostile and constantly changing, the coverage range is affected by transmission power, complexity, and propagation properties [49]. Generally, higher data rates degrade penetration capabilities in an industrial site full of obstacles but at the cost of reduced coverage for network. Coverage of wireless solutions can be extended by deployment of routing, peer-to-peer (P2P) communication, and increasing transmission power using repeaters and power amplifiers. Nevertheless, these techniques increase system complexity and result in less reliability. To summarize, it is necessary to identify the requirements of an individual application and identify the proper trade-off between key performance metrics correspondingly.
