The Extricom WLAN System User Guide 1 Maximum Retries Select the number of times to try to resend a packet if the transmission of the packet fails. Enable Short Preamble: This option becomes available only when selecting 802.11b as the WLAN mode. In this case, mark the checkbox to allow a short preamble. Enable Rate Adaptation Check this box if you want to enable rate adaptation.



• For 802.11a/b/g, all enabled rates participate in the rate adaptation. • For 802.11n devices, rate adaptation will not change the number of data streams .(MCS 0 to 7, or MCS 8 to 15) The following parameters are available if one of the 802.11n-WLAN modes has been selected. Select 802.11n Channel Width Select the width of the 802.11n channel , 20MHz or 40MHz Select 802.11n Secondary Channel If 20/40MHz channel width is selected using the Select Width option, the system automatically configures the second 20MHz channel that will be used for bonding as either above (Upper) or below (Lower)the primary 20MHz channel that is was chosen by the Select channel option). Select 802.11n Blanket operational Mode Two modes are supported: • Mixed mode – In this mode, the Channel Blanket is available to all WLAN clients (802.11a/b/g/n) where 802.11n clients are working in mixed mode • HT only – In this mode, the Channel Blanket is available for 802.11n clients only. Note that in this mode, the 802.11n devices are in fact working in a mixed mode, but the switch will not allow a/b/g devices to connect. Select 802.11n Guard Interval Guard interval can be configured to short (400 nano seconds) or long (800 nano seconds). Note that when a 20MHz channel is configured, it is not possible to configure short guard interval. Select 802.11n MCS Selecting the MCS is equivalent to setting the rate in legacy radios; MCS 0-7 use one data stream, while MCS 8-15 use two data streams. 2 Troubleshooting 802.11a/b/g Rate Configuration Data rate configuration is only applicable to 802.11a/b/g Channel Blankets. For each of the data rates listed, select whether the rate is Basic, Optional, or Disabled. When configuring the data rates, you should consider the data rate capabilities of the wireless devices in your enterprise.    Basic – The Basic data rates are usually the data rates that the vast majority of your wireless devices can support. Only wireless devices that support all the Basic data rates will be connected to the WLAN system. Therefore, it is recommended that you configure a minimal number of Basic data rates that the vast majority or all your wireless devices can support. When working in Mixed Mode, there should be at least one Basic data rate from the 802.11b rates.    Optional – If you configure a data rate as Optional, the network will provide that data rate to wireless devices that can support it.    Disabled – Disabled data rates are not available to wireless devices.



Since the Extricom WLAN system allows for dense deployment of APs, it is recommended, where applicable, to disable low data rates. Not doing so could possibly lead to an “edge user” effect, in which a client reduces aggregate network throughput by moving to the edge of the coverage area. Table 1: Radio Configuration Parameters Configuring WMM Wi-Fi Alliance WMM is an 802.11 quality of service (QoS) implementation based on a subset of the draft 802.11e standard supplement. The WMM specification provides basic prioritization of data packets based on four categories - voice, video, best effort, and background. Prioritization is based on the original Carrier Sense Multiple Access/Collision Avoidance Protocol in the 802.11 standard. In 802.11 the DCF Distributed Coordination Function (DCF) mechanism uses a simple listen-before-talk algorithm to minimize the chance of packet collisions caused by more than one device accessing the wireless medium at the same time. A client must wait for a randomly selected time period and then "listen" to find whether any other device is communicating before starting to transmit. The random back-off period gives all devices a fair opportunity to transmit. WMM (based on 802.11e standard) enhances the DCF by defining a Enhanced Distributed Channel Access (EDCA). EDCA specifies different fixed and random wait times for the four prioritization categories to provide more favorable network access for applications that are less tolerant of packet delays. Devices that have less time to wait have a better chance of being able to transmit than those that have a longer wait. In order of highest priority, the access prioritization categories are voice, video, best effort and background. By default, these four WMM prioritization categories are statically mapped to Ethernet 802.1p prioritization tags to allow consistent QoS across wireless and wired network segments. Flow arriving from the wired network tagged with 802.1p priority is mapped to the appropriate Access category, while WMM flow arrived from the wireless medium is encapsulated and tagged with the appropriate 802.1p priority. The default mappings can be changed by using the pull-down menus that appear under DiffServe conversion to WMM, in Figure 1. Options are Video, Voice, Best Effort, and Background. The back-off timing for each access category consists of a fixed period called the Arbitrary Inter- Frame Space Number (AIFSN) followed by a random period called the Contention Window (CW), both specified in multiples of the slot time. The CW maintains the DCF random back-off component to help avoid collisions of packets from the same access category. The CW range doubles each time there is a collision (starts CWmin up to CWmax) and is reset to its minimum value after a successful transmission. EDCA uses a mechanism called a Transmit Opportunity (TXOP) – a bounded time interval during which a station can send as many frames as possible, but the transmission time must not extend beyond the maximum duration of the TXOP. Each priority level is assigned a TXOP, and this mec…
