Has the RF environment changed since the access points were installed? Is wireless network coverage sufficient to support all users? Does the wireless network provide ubiquitous coverage sufficient to support seamless roaming? Use Wireless EtherScope to capture baseline RF coverage data immediately after the wireless infrastructure is installed, then compare historical data to periodic survey data over time. Use this information to make minor adjustments to wireless access point transmit power, relocate access points, or add new access points before RF environmental changes impact your user community.
