Cisco Systems AIR-ANT2524DB-R - Aironet 2.4GHZ 2DBI and 5GHZ 4DBI Dipole Antenna RP-TNC Black

The next generation of Cisco Aironet 802.11n access points -the Cisco Aironet 3600e Series and 1550 Series- requires the use of dual-band external antennas to make them fully functioning units. As these access points take greater advantage of the multiple-input multiple-output (MIMO) features supported under the 802.11n standard the number of radio transceivers per frequency band has increased. Using dual-band antenna ports allows the access point to support these added transceivers while maintaining a reasonably low number of antenna connections. Each dual-band antenna can transmit or receive Wi-Fi signals in both the 2.4-GHz and 5-GHz bands simultaneously.
