Aruba wireless access control solutions make managing networks of various sizes, with various devices, much easier. This makes it easier for employees to connect to the network with ease. It also improves the user experience and administrative efficiency which helps keep the network secure.
One of the benefits of external antennas is their ability to mount the AP and the antenna separately. This allows the AP to be protected from harsh environmental conditions. The benefit of having an external antenna over an internal one is that it reduces CCI (co-channel interference). With an omnidirectional antenna, the AP will propagate a signal in all directions. Some of the most popular accessories are wireless access point antennas.
One popular antenna is AP-ANT-19, which offers full-band coverage for 802.11b/a/g/n and includes all the hardware to mount indoors or outdoors. It also comes with a tri-band capability, which means you get full-band coverage and omnidirectional coverage in all directions over both bands. If you are looking for something a little more powerful for commercial installations such as retail chains and large office buildings, then you will probably want to investigate the wide band kit 2x2 GP-ANT-2x2-5005-ND. This is a kit of two MIMO antennas for use in 802.11n Mesh Link and Client Access Applications. The kit includes 2 different types of antennas, one horizontal and one vertical, to be used as a 2x2 MIMO pair. They cover the frequency band of 4.9 - 5.875 GHz.
External antennas provide more control over the energy radiated than internal antennas, which often have fixed coverage patterns. External antennas are flexible and can be mounted separately from the access point, protecting it from harsh environmental conditions. This is particularly beneficial in larger open spaces or areas with a high density of APs. They also allow for better performance (by ‘shaping’ RF) and a lower price point. If your issues are just with one external antenna, you may end up saving money by only changing that antenna.
