Choosing the Right Access Point

Modularity and Smart Antenna Connector Ports

In addition there is an mGig port as well as a port for external modules on the AP 3800.

Modularity and Smart Antenna Connector Ports
The AP 3800 has modularity support that is a bit different from the original module design on the prior AP
3600 and AP 3700 series. This module design allows for installation onto the side of the access point. This
allows for larger antenna arrays and does not constrict the development of Cisco and potentially third party
modules as they are no longer limited by the physical size of the cccess point. Additionally, filtering is installed
on the AP 3800 for cellular and other radio coexistence.
The external antenna connectors on the "E" and "P" series are identical to the antenna connectors on previous
access points. There is no difference in operation when the access point is used in dual band (2.4 and 5 GHz)
operation. which is the default mode. RF coverage and cell sizes are similar to the previous AP 2700 and 3700
series so there is no need to do a new site survey.
Unlike the prior external antenna versions, the new 2800 and 3800 series Access Points now support the
capability of dual 5–GHz operation. When in this mode, a smart antenna connector must be used on the
external antenna models, as the additional 5–GHz radio cannot use the same top antennas on the access point
that are being used by the primary 5–GHz radio.
