My company uses wireless B for connecting the antennas of our corporate headquarters in the vicinity (approx. 1 mile) of satellite offices. We never had problems with connectivity, in addition to the re-connection after a few weeks.

Last, a lot of construction came to our place mall. There are bars and bars everywhere, and all ground equipment and blankets. We have seen a significant drop in the reliability of our wireless services, and not in a position to bring the matter to an individual plant. What is the probability that the construction of the fence is the culprit? If so, what are the steps you can take to prevent this interference?
