Improved deployment flexibility - Planners can choose an antenna pattern that meets coverage
requirements while allowing for convenient AP placement and installation.
Improved coverage and performance - External antennas allow planners to optimize coverage
and deliver higher available data rates to user concentrations.
Can provide a low cost fix for trouble spots - Appropriately outfitting existing APs with
external antennas can greatly improve coverage and available data rates in areas that are not
adequately serviced.
Increased security - Perimeter access points outfitted with directional external antennas can
focus energy inwards and increase security by preventing signal "leakage" outside the office.
Improved aesthetics - External antennas feature a 3 foot cable that allows the connected access
point to be installed out-of-sight.
Lower cost of coverage - External antennas improve overall system efficiency by effectively
directing available energy to where it's needed. This ensures overall system utility is
maximized for any installation.
