Extricom Series WLAN System Installation and User Guide 

11 

Overview of the Extricom Series Access Points 

Access Points with Internal Integrated Antennas 

The two-radio AT-EXRP-22n and three-radio AT-EXRP-32n are 802.11n access points with 
internal antennas for maximum throughput and easy deployment of 802.11n with or without legacy 
Wi-Fi. The AT-EXRP-22n is equipped with two, and the AT-EXRP-32 - with three, dual-stream 
radios, each of which can be operated on the 2.4 GHz or 5 GHz band. Each radio has a 2x2 MIMO 
antenna configuration for an air rate of up to 300 Mbps. 

The APs do not require configuration, enabling plug-and-play installation. If stolen, the APs do not 
pose a security risk, since all encryption is performed in the switch. 

With all intelligence residing in the WLAN switch, APs may be placed as close together as 
necessary to provide high-quality, high-speed connectivity from all locations within the enterprise.  

Extricom Series APs are connected to the Extricom Series WLAN Switch via standard Cat5e/6 
cables. The APs are powered by the standard 802.3af Power over Ethernet (PoE), and only a single 
Cat5e/6 cable connection is required to support all radios in an Extricom Series AP. 

An EXRE-1000 range extender can be used between the AP and the switch, for extended reach.

Access Points with Connectors for External Antennas 

Some applications may require an access point capable of connecting to external antenna(s). The 
AT-EXRP-22En accommodates this requirement. The AT-EXRP-22En contains two dual-stream 
802.11a/b/g/n radios and four external antenna connectors. 

An external antenna may be desired to make the AP less visible by mounting it in the plenum. The 
situations may arise, in which to ensure connectivity and service levels within a complex coverage 
environment, directional antennas may be needed, rather than the omni-directional antennas that are 
standard inside Extricom Series integrated antenna APs. In such cases, the antennas may also be 
located at some distance from the AP in order to cover a specific area.
