• Flexible Radio / Antenna Options using external antenna "e" series models
3 What is a SMART antenna connector?
The Cisco Aironet AP‐3802E, AP‐3802P, and AP‐2802E contain a SMART antenna connector, which
is connected directly to the flexible radio. Without a Smart antenna, the flexible radio must stay in 2.4GHz
only mode. Once a Smart a ntenna is connected, the flexible radio can be used in the full flexible radio
Assignment mode, allowing dual 5–GHz, wireless security monitoring, and future modes.
The Smart antenna connector can be used to connect to AIR‐CAB002‐DART‐R= which allow any
RP‐TNC based Aironet antenna to connect to the Smart Antenna port. In addition, future Smart Antennas
will be released at future times.
4 What is the Extension module slot used for?
The module slot on the AP 3802I, AP 3802E, and AP 3802P can be used to insert future modules.
Some of the proposed modules are:
• 3G and LTE Small Cell Offload
• Bluetooth Beaconing (BLE)
• Future Wi-Fi upgrades to meet new IEEE standards
• Video Surveillance
• Custom Applications using Linux
5 Why is the Extension module slot on the side?
The sidecar module architecture allows Network Engineers the ability to add/swap modules without
dismounting the access point from the mounting bracket. Additionally, it frees the optional module from
the constraints of being inside the AP.
6 What kind of plastic is AP 2800 and AP 3800 made of and is it suitable for use in hospital cleanroom
environments?
The plastic material used on the AP 2800 and AP 3800 series is Lexan 945. This material was tested for
clean room use with a Steris Chemical (trademark name SPOR-KLENZ )

7 Looking at the specification sheets, I noticed the Cisco AP 1850 supports 4x4:4 and the AP 2800/3800
supports 4x4:3. Why does the AP 1850 support one more spatial stream? How does this help me?

60
◦ Both radios can be setup in HDX mode for Micro cells with external antenna models
◦ Both radios can be set up in Macro cell mode with external antenna to provide two wide area
cells
◦ Different antennas can be used on each 5G radio for different coverage patterns (Omni and
Directional); or one radio can serve one coverage cell while the other radio is used for a
different classroom or outdoor coverage
◦Permits greater RF flexibility allowing XOR to combine with dedicated 5–GHz in DRE mode
(default) OR SRE mode for a 5G/5G or separate 2.4/5G or DRE 2.4 & 5G (dual band mode)
