In the industrial world, personnel often have to work in some remote areas where they may not be connected with any internet services. This is particularly true in regions like forests, high sea, mountains, etc. In such cases, the industries normally prefer to establish industrial wireless radio service whereby it would be possible to establish connectivity with its workforce by making use of radio frequencies. You can find many agencies specialized in providing such long range wireless Ethernet services that are known to secure very efficient connectivity with the staff working in the field station.
When designing any system, engineers and system architects usually want to know how well the various components of the system will perform. In a microprocessor, logic or other digital system these questions usually are answered in terms of clock speeds, instructions per second or data throughput. With wireless communication, the most common performance questions involve range.
