materials that can withstand harsh environments. However, con- tinual exposure to UV light, or periodic submersion should be avoided to extend the life of the components.
Communication between the base and remote modules are rated for distances as great as 1/2 mile (800 meters), line of sight. However, obstructions such as buildings and industrial equipment between the modules may reduce the effective dis- tance.
Typically, the modules are suspended inside a manhole. Sus- pending the module near the opening will protect it from the ele- ments, minimize the chance of submersion, and allow it to be easily retrieved without entering the manhole. In most instances, this location near the opening will allow for successful wireless communication.
Typical communication distances possible using internal antennas are:
•
•Inside closed manhole: 100 feet (30m)
