Wi Fi wireless networks On APs without WMM QoS all traffic streams are given the same access priority to the wireless network If the introduction of another traffic stream creates a data transmission demand that exceeds the current network capacity then the new traffic stream reduces the throughput of the other traffic streams The NWA uses WMM QoS to prioritize traffic streams according to the IEEE 802 1q or DSCP information in each packet s header The NWA automatically determines the priority to use for an individual traffic stream This prevents reductions in data transmission for applications that are sensitive to latency and jitter variations in delay NWA1120 Series User s Guide Chapter 6 Wireless LAN 6 10 2 1 WMM QoS Priorities The following table describes the WMM QoS priority levels that the NWA uses Table 25 WMM QoS Priorities Priority Level description voice WMM VOICE Typically used for traffic that is especially sensitive to jitter Use this priority to reduce latency for improved voice quality video WMM VIDEO Typically used for traffic which has some tolerance for jitter but needs to be prioritized over other data traffic best effort WMM BESTEFFORT Typically used for traffic from applications or devices that lack QoS capabilities Use best effort priority for traffic that is less sensitive to latency but is affected by long delays such as Internet surfing

AES No Enable WPA2 PSK TKIP AES Yes Disable Antenna Overview An antenna couples RF signals onto air A transmitter within a wireless device sends an RF signal to the antenna which propagates the signal through the air The antenna also operates in reverse by capturing RF signals from the air Positioning the antennas properly increases the range and coverage area of a wireless LAN Antenna Characteristics Frequency An antenna in the frequency of 2 4GHz or 5GHz is needed to communicate efficiently in a wireless LAN Radiation Pattern A radiation pattern is a diagram that allows you to visualize the shape of the antenna s coverage area Antenna Gain Antenna gain measured in dB decibel is the increase in coverage within the RF beam width Higher antenna gain improves the range of the signal for better communications For an indoor site each 1 dB increase in antenna gain results in a range increase of approximately 2 5 For an unobstructed outdoor site each 1dB increase in gain results in a range increase of approximately 5 Actual results may vary depending on the network environment Antenna gain is sometimes specified in dBi which is how much the antenna increases the signal power compared to using an isotropic antenna An isotropic antenna is a theoretical perfect antenna that sends out radio signals equally well in all directions dBi represents the true gain that the antenna provides Types of Antennas f
