    There are slight differences in the weight and thickness of the 2800 and 3800. The AP 3800 is a bit more robust as it has support for mGig (NBASE-T) and optional module support. AP 2800 on left is smooth and does not have heat fins. Figure 4: AP 2800/3800 Dimensions Cisco Aironet Series 2800/3800 Access Point Deployment Guide...

    The weight is slightly different between the models.AP 3800 both “E” and “P” versions as well as the Note 2800e is 2.1 kg.AP 3800i is 2.0 kg. AP 2800i is 1.6 kg. Both products use the same brackets as 2700/3700 2700/3700 Series Access Points–AIR-AP-BRACKET1 and AIR-AP-BRACKET-2. Cisco Aironet Series 2800/3800 Access Point Deployment Guide...

    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.

    When a smart antenna connector is installed, the XOR radio (the radio that is defined in software as Radio 0) now has its RF switched to the smart antenna connector. Figure 10: External connector ports on AP 2800e and 3800e Cisco Aironet Series 2800/3800 Access Point Deployment Guide...

    There are many different installation options available depending upon the business requirements. Brackets are available from Cisco as well as third-party companies. During the ordering process, the customer may choose one of two brackets (but not both). Each bracket is a zero-dollar ($0) option at the time of configuration.

    When mounting APs to ceiling channel rails such as the ones shown in Figure 14, an optional channel adapter is used: AIR-CHNL-ADAPTER. It comes in a two-pack and attaches to the ceiling grid clip above. Cisco Aironet Series 2800/3800 Access Point Deployment Guide...

    If you have this bracket currently installed and are migrating to the newer AP 2800 and AP 3800 series, you may be able to still use the existing tile and leverage the new in-tile mount available from Oberon Wireless (a Cisco partner).

  • Page 21: Cisco Aironet Series 2800/3800 Access Point Deployment Guide

    Many hospitals and other carpeted Enterprise environments prefer a more streamlined look and wish to install the AP directly into the tile. This can be done on prior Cisco AP products using the optional Cisco AIR-AP-BRACKET-3.

    If there is a desire to change the color of an AP, rather than painting the AP which would void the warranty, consider using colored vinyl tape or using a colored plastic cover from Oberon.

  • Page 26: Clean Rooms (Healthcare)

    Many hospitals and factories have requirements to wipe down or gently spray the environment with a chemical (often diluted liquid that has cleaning / disinfectant properties). The Cisco AP 2800 and AP 3800 are designed with a purpose–build Wi-Fi chipset using Enterprise and industrial class components. This enables the AP enclosure to have a Plenum rating and is vent-less, so the unit is ideal for these types of applications.

  • Page 29: Understanding Flexible Radio Assignment (Software Overview)

    The flexible radio is similar to the previous XOR radio used in the Cisco WSSI/WSM modules for the AP 3700, but this new flexible radio module is able to be configured to serve clients in either 2.4-GHz or 5–GHz or serially scan both 2.4-GHz and 5–GHz on the flexible radio while the main 5–GHz radio serves clients.

    When using FRA with external antenna ("E/P" models) the antennas may be placed to enable the creation of two completely separate Macro (wide area cells) or two Micro cells (small cells) for HDX or any combination. Cisco Aironet Series 2800/3800 Access Point Deployment Guide...

    This results in non-linear traffic and increases the overall channel utilization as clients compete for "airtime". Figure 28: Single 5 GHz and 2.4 GHz cell (default mode) Channel Utilization at 60% Cisco Aironet Series 2800/3800 Access Point Deployment Guide...
  • Page 32: Cisco Aironet Series 2800/3800 Access Point Deployment Guide

    Net result, channel utilization is now reduced to 20% on channel 36 and 24% on channel 108. Currently both Macro (green) and Micro (yellow) cells use the same SSID by design; later releases will likely allow for different SSIDs. Cisco Aironet Series 2800/3800 Access Point Deployment Guide...

    Later PoE standards have since emerged with 802.3at providing up to 30 Watts at the Power Sourcing Equipment (PSE). Many of Cisco's previous access points such as the AP-1850 and AP-3700 worked best with the higher power sources 802.3at and PoE+ but would function with "reduced functionality" if powered by the older 802.3af 15.4W powering systems.

    If the access point is installed using a "side arm" type mount or other mounting locations where there is a likelihood of high vibration, it is recommended that a padlock or metal pin be used to prevent the AP from vibrating loose from the bracket.

  • Page 65 Frequently Asked Questions (FAQ's) When designing the AP 2800 and AP 3800 Cisco wanted to bring the very best technology into the device. A trade-off was made to support dual 5–GHz 160 MHz rather than the extra spatial stream, as the additional spatial stream provides little real benefit.
  • Page 66 Customers should be discouraged from running legacy TKIP as that feature has been deprecated by the Wi-Fi Alliance. Cisco understands there are healthcare customers using legacy equipment with a need for TKIP support. The 1830, 1850, 2800 and 3800 does not currently support TKIP but there are plans to support it in the 8.3MR1 release.
