This appendix describes how to build a WLAN around your OM2P-LC/OM2P-HS using he device’s operating modes.
13.1 Access Point Mode In Access Point Mode, OM2P-LC/OM2P-HS behaves likes a central connection for stations or clients that support IEEE 802.11b/g/n networks. Stations and client must be configured to use the same SSID and security password to associate with the OM2P-LC/OM2P-HS. The OM2P-LC/OM2P-HS supports four SSIDs at the same time for secure guest access. 13.2 Access Point Mode with WDS Function The OM2P-LC/OM2P-HS Access Point Mode also supports WDS functionality. This operating mode allows wireless connections to the OM2P-LC/OM2P-HS using WDS technology. In this mode, configure the MAC addresses in both Access Points to enlarge the wireless area by enabling WDS Link settings. WDS supports eight AP MAC addresses.  Not every Access Point device supports WDS in Access Point Mode. As a result, to use WDS, we recommend you use the OM2P-LC/OM2P-HS.
13.3 Client Bridge Mode In Client Bridge Mode, the OM2P-LC/OM2P-HS behaves like a wireless client that connects to an Access Point wirelessly and allows users to surf the Internet whenever they want. In this mode, use the OM2P-LC/OM2P-HS Site Survey to scan for Access Points within range. Then configure the OM2P-LC/OM2P-HS SSID and security password accordingly to associate with the Access Point. In this configuration, the station has a wired Ethernet connection to the OM2P-LC/OM2P-HS LAN port. 13.4 WDS Bridge Mode In WDS Bridge Mode, the OM2P-LC/OM2P-HS can wirelessly connect different LANs by configuring the MAC address and security settings of each OM2P-LC/OM2P-HS device. Use this mode when two wired LANs located a small distance apart want to communicate with each other. The best solution is to use the OM2P-LC/OM2P-HS to wirelessly connect two wired LANs, as shown in the following figure. WDS Bridge Mode can establish 16 WDS links, creating a star-like network.  WDS Bridge Mode is unlike Access Point. Access Points linked by WDS are using the same frequency channel, more Access Points connected together may lower throughput. Please be aware to avoid loop in your wireless connection, otherwise enable Spanning Tree Function.
13.5 Client Router Mode In Client Router Mode, the OM2P-LC/OM2P-HS’s internal DHCP server allows a number of LANs to automatically generate IP addresses to share the same Internet. In this mode, connect an AP/WISP wirelessly and connect to LANs via a wired connection. 13.6 RADIUS Connections Remote Authentication Dial In User Service (RADIUS) authentication is available when configuring the OM2P-LC/OM2P-HS wireless advanced settings (see Chapter 8). Use this feature if you have a RADIUS server. WPA(TKIP), WPA2(AES), and WPA2 Mixed encryption types are also supported. The following figure shows an example of a RADIUS configuration, where two OM2P-LC/OM2P-HS devices installed at different locations communicate with each other wirelessly. In this configuration, one OM2P-LC/OM2P-HS is configured for Access Point Mode and connected to a RADIUS server via a switch, while the other OM2P-LC/OM2P-HS is configured for Client Bridge Mode. The RADIUS server uses an authentication scheme such as PAP or CHAP to verify a user's identification, along with, optionally, other information related to the request, such as the user's network address or phone number, account status and specific network service access privileges. The RADIUS server then returns one of three responses to the OM2P-LC/OM2P-HS : Access Reject (user is denied access to all requested network resources), Access Challenge (requests additional information from the user such as a secondary password), PIN, token or card), or Access Accept (user is granted access).

The network
detects the collision of the two transmitted packets and discards both of them. CoverageThe region within which a paging receiver can reliably receive the transmission of paging signals. CoverageAreaThe geographical area that can be served by a mobile communications network or system. CoverageHoleAn area within the radio coverage footprint of a wireless system where the RF signal level is below the design threshold. Physical obstructions such as buildings, foliage, hills, tunnels, and indoor parking garages are usually the cause of coverage holes. CyclicRedundancyCheck(CRC)Acommontechniquefordetectingdatatransmissionerrors.DynamicHostConfigurationProtocol(DHCP)A protocol that assigns temporary IP addresses automatically to client stations logging onto an IP network, so the IP addresses do not have to be assigned manually. The OM2P-LC/OM2P-HS contains an internal DHCP server that automatically allocates IP address using a user-defined range of IP addresses. DeadSpotAn area within the coverage area of a WLAN where there is no coverage or transmission falling off. Electronic interference or physical barriers such as hills, tunnels, and indoor parking garages are usually the cause of dead spots. See also coverage area. 802.11A category of WLAN standards defined by the Institute of Electrical and Electronics Engineers (IEEE). 802.11aAn IEEE standard for WLANs that operate at 5 GHz, with data rates up to 54 Mbps. 802.11bAn IEEE standard for WLANs that operate at 2.4 GHz, with data rates up to 11 Mbps. 802.11gAnIEEEstandardforWLANsthatoperatesat2.4GHz,withdatarateof300Mbps.ThenewstandardalsoraisestheencryptionbartoWPA2.The40HToptioncanbeaddedtoincreasethedatarate.EncryptionTranslates data into a secret code to achieve data security.
