[. . . ] DTIM count Specify the DTIM period in the wireless beacon. Client stations use the DTIM to wake up from low-power mode to receive multicast traffic. The DTIM counts down with each beacon that is sent. Therefore if the DTIM is set to 5, then client stations in low-power mode will wake up every 500 ms (. 5 second) to receive multicast traffic. Transmit/receive on Select the radio on which this VSC will transmit and receive. Broadcast name (SSID) When this option is enabled, APs will broadcast the wireless network name (SSID) to all client stations. Most wireless adapter cards have a setting that enables them to automatically discover APs that broadcast their names and connect to the one with the strongest signal. If you disable this option, client stations will have to specify the network name you enter for Name (SSID) when they connect. Advertise Tx power When this option is enabled, APs broadcast their current transmit power setting in the wireless beacon. It also enables support for 802. 1h and 802. 1 1d. Broadcast filtering Use this option to conserve wireless bandwidth by filtering out non-essential broadcast traffic. Multicast traffic exchanged between VSCs is always controlled by the setting of the senders VSC. Generally, most clients will be involved in the bidirectional exchange of unicast packets. In this case, the rules can be simplified by assuming that the most restrictive setting for this option takes precedence. For example: • If VSC1 is set to No and VSC2 is set to All, no communication is permitted between clients on the two VSCs, or between clients on VSC1. However, all clients on VSC2 can communicate with each other. If VSC1 is set to 802. 1X and VSC2 set to All, only 802. 1X clients can communicate between the two VSCs. • 66 Working with VSCs Quality of service The quality of service (QoS) feature provides a number of different mechanisms to prioritize wireless traffic sent to wireless client stations. See “Quality of service (QoS)” (page 75). Allowed wireless rates Select the wireless transmission speeds (in Mbps) that this VSC will support for each wireless mode. Clients will only be able to connect at the rates that you select. If a client does not support the selected rate and mode, it will not be able to connect to this VSC. Note that all APs do not support all wireless modes and rates. See “Wireless mode” (page 39) for details. To ensure a high quality of service for voice applications, disable all rates below 5. 5. Also, ensure that the radio is configured as follows: • • Operating mode is set to Access point only. [. . . ] In the USA, these antennas can be only be used in the 5725-5850 MHz band. 802. 1 1a/b/g antennas for MSM APs Antennas included with MSM310, MSM310-R, MSM320, and MSM320-R Included with Antenna Type 2. 4 MSM310 & MSM320(J9401A) MSM310-R & MSM320-R Omni Omni 2. 5 dBi 5. 6 dBi Antenna Band (GHz) 5. 15 - 5. 35 3. 0 dBi N/A 5. 47 - 5. 725 3. 4 dBi NA 5. 725 - 5. 850 3. 4 dBi N/A 128 Connecting external antennas CAUTION: When using antennas outdoors, a lightning arrestor is required for lightning protection. Consider placing the lightning arrestor immediately before the antenna cable enters the building. HP offers a lightning arrestor as an accessory, HP product number J8996A. All HP devices are designed to be compliant with the rules and regulations in locations they are sold and will be labeled as required. [. . . ]
