  • Page 4: Introduction

    Introduction The TT5800 is Teletronics’s answer to the ever growing demand for higher bandwidth and security in a wireless network environment. It is based on a brand new redesigned platform that not only offers faster performance and capacity but also supports all current pre IEEE 802.11i wireless security standards. The TT5800 is the IEEE 802.11a version of the platform that directly targets the need for the more secure, less crowded 5.8 GHz frequency spectrum.

    Connect the 48VDC power adapter to the power jack on the PoE injector to power on the TT5800/TT2400. Check the LEDs on the TT5800/TT2400 to confirm if the status is okay. At this point the Power (PWR) LED indicator should be red and Ethernet (LAN) LED should be green. The RF light should light up once the unit is associated wirelessly with another wireless device.

  • Page 20 WPA Configuration Short for Wi-Fi Protected Access, WPA is a Wi-Fi standard that was designed to improve upon the security features of WEP. WPA has the following improvements over WEP: • Improved data encryption through temporal key integrity protocol (TKIP). TKIP scrambles the keys using a hashing algorithm.
  • Page 21 Cipher Type • TKIP Temporal Key Integrity Protocol is an upgrade to the WEP known as WEP 1.1 that fixes known security problems in WEP’s implementation of the RC4 stream cipher. TKIP scrambles the keys using a hashing algorithm and by adding an integrity-checking feature, ensures that the keys haven’t been tampered with.
  • Page 22 the MAC address does not provide sufficient security because the MAC address of a wireless client can be spoofed. • Shared Key - Shared key authentication supports authentication of stations as either a member of those who know a shared secret key or a member of those who do not. Shared key authentication is not secure and is not recommended for use.
  • Page 23 Admin Device Name This is the name that the bridge will use to identify itself to external configuration and IP address programs. This is not the same as the SSID. It is okay to leave this blank if you are not using these programs. SNMP Setting SNMP enable Option to enable or disable SNMP support.
  • Page 24 Community The SNMP Read-only Community string is like a user id or password that allows access to a router's or other device's statistics or management information. InterMapper sends the community string along with all SNMP requests. If the community string is correct, the device responds with the requested information. If the community string is incorrect, the device simply discards the request and does not respond.

The 802.11d specification is well suited for systems that want to provide global Roaming. ACK Timeout When a packet is sent out from 802.11 Station A it will wait for an 'ACKnowledgement frame' from 802.11 Station B.

  • Page 34 Channel Channels are important to understand because they affect the overall capacity of your Wireless LAN. A channel represents a narrow band of radio frequency. A radio frequency modulates within a band of frequencies; as a result there is a limited amount of bandwidth within any given range to carry data. It is important that the frequencies do not overlap or else the throughput would be significantly reduced as the network sorts and reassembles the data packets sent over the air.
  • Page 35 • Channel 153 = 5.745 – 5.765 • Channel 157 = 5.765 – 5.785 • Channel 161 = 5.785 – 5.805 • Channel 165 = 5.805 – 5.825 Special Atheros Turbo Mode Channels *Use this setting only when both side of the wireless connection is using the Atheros chipset. The radio will combine 2 free channels for the wireless transmission to double the bandwidth.

  • Page 39 Remote RADIUS server configuration settings. There are two sections to setup 2 RADIUS servers for the TT5800/TT2400 to connect to. At any given time the TT5800/TT2400 will connect to one RADIUS server for authentication and will use the other one as a backup if that option is configured.
  • Page 40 RADIUS server shared secret When registered with a RADIUS server, a password will be assigned. This would be the RADIUS server shared secret. MAC Address Authentication Use client MAC address for authentication with RAIDUS server. WEP Configuration Short for Wired Equivalent Privacy, a security protocol for wireless local area networks (WLANs) defined in the 802.11b standard.
  • Page 41 Shared key authentication uses the following process: 6. The authentication-initiating wireless client sends a frame consisting of an identity assertion and a request for authentication. 7. The authenticating wireless node responds to the authentication-initiating wireless node with challenge text. 8. The authentication-initiating wireless node replies to the authenticating wireless node with the challenge text that is encrypted using WEP and an encryption key that is derived from the shared key authentication secret.

  • Page 47 Advanced Advanced Wireless Fragmentation threshold Fragmentation Threshold is the maximum length of the frame beyond which payload must be broken up (fragmented) into two or more frames. Collisions occur more often for long frames because sending them occupies the channel for a longer period of time, increasing the chance that another station will transmit and cause collision.
  • Page 48 Burst time Maximum burst time is a feature based on the PRISM Nitro; a new WLAN software solution that more than triples 802.11g throughput in a mixed-mode environment and offers up to 50 percent greater throughput performance in 802.11g-only networks. PRISM Nitro is fully IEEE 802.11 compliant and uses prioritization algorithms and enhanced protection mechanisms to significantly increase wireless networking performance.The recommended value for the maximum burst time for 11b or the mixed 11b/g environment is 650.
  • Page 49 When a packet is sent out from 802.11 Station A it will then wait for an 'ACKnowledgement frame' from 802.11 Station B. Station A will only wait for a certain amount of time (ACK timeout) or ACK window. If the ACK is NOT received within that timeout period then the packet will be re-transmitted from Station A resulting in reduced throughput.

  • Page 57: Appendix F: Tt2400/Tt5800 Upgrade Faq

    Teletronics has now removed the necessary step to provide an activation key to change from SU to AP and vice versa in our TT2400 and TT5800 product line. For example, if you have a TT2400 in SU mode with 3.6.0 firmware, the activation key is not required if you upgrade to either 3.7.0 (SU mode) or 3.7.1 (AP mode), or later.
  • Page 58 Will upgrade keep my previous configuration? Although the upgrade might keep your previous configuration, we suggest customer to reset the unit to factory default located in “admin” section and configure it again.

  • Page 59: Appendix G: Antenna Diversity

    Using the default “Diversity” option might not be the best option to achieve optimal performance. Please configure “Use Antenna #2” for TT2400 and “Use Antenna #1” for TT5800 to force the cards to use only those ports at all times for both RX and TX operations. This will under most cases give you extra output power and receive sensitivity.

  • Page 60: Appendix H: Troubleshooting

    Resolution: If you forgot the IP address of the TT5800/TT2400 you can press reset button to restore the default factory settings by holding down the reset button for 10 seconds. The factory default IP for Client Bridge mode is 192.168.10.241, and Access Point mode is 192.168.10.240.
