Cisco Aironet 1840 Series Access Points
The AP supports both Cisco Mobility Express and lightweight deployments (using Cisco Wireless controllers). The AP
also supports the following operating modes:
Local—This is the default mode for the Cisco AP. In this mode, the AP does not serve clients.
Flexconnect—Flexconnect mode for the Cisco AP.
Monitor—This is the monitor-only mode for the Cisco AP.
Sniffer—In the wireless sniffer mode, the AP starts sniffing the air on a given channel. It captures and forwards all the
packets from the clients on that channel to a remote machine that runs Airopeek or Wireshark (packet analyzers for
IEEE 802.11 wireless LANs). This includes information on the time stamp, signal strength, packet size, etc.
Note In the sniffer mode, the server to which the data is sent should be on the same VLAN as the wireless
controller management VLAN otherwise an error will be displayed.
AP Model Numbers and Regulatory Domains
The ‘x’ in the model numbers represents the regulatory domain. You need to verify whether the AP model you have is
approved for use in your country. To verify approval and to identify the regulatory domain that corresponds to a particular
country, visit http://www.cisco.com/go/aironet/compliance. Not all regulatory domains have been approved. As and
when they are approved, this compliance list will be updated.
Antennas and Radios
The 1840 series access point contains a 2.4 GHz radio and a 5 GHz radio. The 1840I has 4 internal antennas.
