Introduction AP-4000 Series User Guide Introduction to Wireless Networking Introduction to Wireless Networking An Access Point extends the capability of an existing Ethernet network to devices on a wireless network. Wireless devices can connect to a single Access Point, or they can move between multiple Access Points located within the same vicinity. As wireless clients move from one coverage cell to another, they maintain network connectivity. In a typical network environment (see Figure 1-1)

For information on converting an AP-4000 into an AP-4000M to enable Mesh functionality, see Mesh Software Kit. In a mesh network, access points use their wireless interface as a backhaul to the rest of the network. Access points connected directly to the wired infrastruc

Introduction AP-4000 Series User Guide Mesh Networking (AP-4000M/4900M Only) are discovered, MAP2 through MAP8 will build a neighbor table from the beacons and probe responses they receive. The neighbor table contains three kinds of links: • Active: Link with a mesh neighbor that has gone through association and authentication, and the port is open. • Connected: Link with a mesh neighbor that has gone through association and authentication, but the port is closed. • Disconnected: Possible link

Introduction AP-4000 Series User Guide Mesh Networking (AP-4000M/4900M Only) from MAP4 to MP1 fails, MAP4 can still reach the backbone via MAP3 and MAP2. The same goes for other MAPs that discover each other. After a short while, the network in this example will look like Figure 1-4, where solid lines indicate active Mesh links and dotted lines indicate established but inactive Mesh links. Figure 1-4 Mesh Startup Topology Example – Step 3 In this example, if MAP8 loses the Mesh link to MP1,

Introduction AP-4000 Series User Guide Guidelines for Roaming – 18 Mbps throughput is available at the portal (max is 25 Mbps, but APs will back off as distance between them increases). – 20 wireless clients are supported per AP. – Average utilization (time that a client is actually transferring data) is 10%. If the conditions on your network are different than the assumptions above, then the maximum number of APs should be adjusted accordingly. NOTE: Clients whose traffic must traverse multip

Introduction AP-4000 Series User Guide IEEE 802.11 Specifications • In countries that require passive scanning for Mesh, the roam time may be higher. • When an AP-4000M/4900M is mounted in a vehicle and is being used in a Mesh network, there will be limited connectivity when the vehicle is moving. IEEE 802.11 Specifications In 1997, the Institute of Electrical and Electronics Engineers (IEEE) adopted the 802.11 standard for wireless devices operating in the 2.4 GHz frequency band. This standar

Introduction AP-4000 Series User Guide Management and Monitoring Capabilities Users enter Command Statements, composed of CLI Commands and their associated parameters. Statements may be issued from the keyboard for real time control, or from scripts that automate configuration. For example, when downloading a file, administrators enter the download CLI Command along with IP Address, file name, and file type parameters. You access the CLI over a HyperTerminal serial connection or via Telnet. Du

Introduction AP-4000 Series User Guide Management and Monitoring Capabilities • Privacy (a.k.a Encryption): Protects against disclosure of message payload. • Access Control: Controls and authorizes access to managed objects. The default SNMPv3 username is administrator, with SHA authentication, and DES privacy protocol. SSH (Secure Shell) Management You may securely also manage the AP using SSH (Secure Shell). The AP supports SSH version 2, for secure remote CLI (Telnet) sessions. SSH provides
