Chapter 11 Wireless LAN Table 28 Expert > Wireless (continued) LABEL Name (SSID) Hide SSID Channel Selection DESCRIPTION The SSID (Service Set IDentity) identifies the Service Set with which a wireless client is associated. Enter a descriptive name (up to 32 printable characters found on a typical English language keyboard) for the wireless LAN. Select this check box to hide the SSID in the outgoing beacon frame so a station cannot obtain the SSID through scanning using a site survey tool. Select a channel from the drop-down list box. The options vary depending on the frequency band and the country you are in. Operating Channel Channel Width This option is only available if Auto Channel Selection is disabled. This displays the channel the ARMOR Z1 is currently using. Select the wireless channel width used by ARMOR Z1. A standard 20MHz channel offers transfer speeds of up to 144Mbps (2.4GHz) or 217Mbps (5GHZ) whereas a 40MHz channel uses two standard channels and offers speeds of up to 300Mbps (2.4GHz) or 450Mbps (5GHZ). Because not all devices support 40 MHz channels, select Auto 20/40MHz to allow the ARMOR Z1 to adjust the channel bandwidth automatically. 40MHz (channel bonding or dual channel) bonds two adjacent radio channels to increase throughput. The wireless clients must also support 40 MHz. It is often better to use the 20 MHz setting in a location where the environment hinders the wireless signal. 802.11 Mode Select 20MHz if you want to lessen radio interference with other wireless devices in your neighborhood or the wireless clients do not support channel bonding. If you set Band to 2.4GHz, you can select from the following: • 802.11b: allows either IEEE 802.11b or IEEE 802.11g compliant WLAN devices to associate with the ARMOR Z1. In this mode, all wireless devices can only transmit at the data rates supported by IEEE 802.11b. • 802.11g: allows IEEE 802.11g compliant WLAN devices to associate with the Device. IEEE 802.11b compliant WLAN devices can associate with the ARMOR Z1 only when they use the short preamble type. • 802.11bg: allows either IEEE 802.11b or IEEE 802.11g compliant WLAN devices to associate with the ARMOR Z1. The ARMOR Z1 adjusts the transmission rate automatically according to the wireless standard supported by the wireless devices. • 802.11n: allows IEEE 802.11n compliant WLAN devices to associate with the ARMOR Z1. This can increase transmission rates, although IEEE 802.11b or IEEE 802.11g clients will not be able to connect to the ARMOR Z1. • 802.11gn: allows either IEEE 802.11g or IEEE 802.11n compliant WLAN devices to associate with the ARMOR Z1. The transmission rate of your ARMOR Z1 might be reduced. • 802.11 bgn: allows IEEE802.11b, IEEE802.11g and IEEE802.11n compliant WLAN devices to associate with the ARMOR Z1. The transmission rate of your ARMOR Z1 might be reduced. If you set Band to 5GHz, you can select from the following: Security • 802.11a: allows only IEEE 802.11a compliant WLAN devices to associate with the ARMOR Z1. • 802.11a/an: allows both IEEE802.11n and IEEE802.11a compliant WLAN devices to associate with the ARMOR Z1. The transmission rate of your ARMOR Z1 might be reduced. • 802.11a/an/ac: allows IEEE802.11n, IEEE802.11a and IEEE 802.11c compliant WLAN devices to associate with the ARMOR Z1.
