Using the WBPN Wireless-N Bridge for Phone Adapters Configuration Utility Configuring Wireless Parameters 2 STEP 3 Choose the Network Type: • Infrastructure-The WBPN is connected to the wireless network through a wireless router or access point (AP). • Ad-hoc-The WBPN directly communicates with other devices in the adhoc network. Each device must be configured with the same SSID and channel number in order to communicate with other devices in the ad-hoc network. STEP 4 If you chose the ad-hoc network type, you can configure the following parameters: • Channel width-Choose to manually configure the channel bandwidth for Wireless-N connections. When it is set to 20MHz, only the 20MHz channel is used. When it is set to 40MHz, Wireless-N connections will use the 40MHz channel but Wireless-B and Wireless-G connections will still use the 20MHz channel. If there is no Wireless-B nor Wireless-G broadcast, selecting 40Mhz will enhance the throughput. This field is unavailable if you chose the infrastructure network type. • Control Sideband- Specify if the extension channel should be in the Upper or Lower sideband. This field is not configurable if you chose the infrastructure network type. • Channel Number-Select the appropriate channel from the list. Select the same channel on which the other ad-hoc devices in the network are broadcasting. This field is not configurable if you chose the infrastructure network type. • Data Rate-Select the data transmission speed. This field is not configurable if you chose the infrastructure network type. STEP 5 Wi-Fi Multimedia (WMM) is a component of the IEEE 802.11e wireless LAN standard for quality of service (QoS). It specifically supports priority tagging and queuing. It is enabled by default when the band is set to N, G+N, or B+G+N. You can choose to disable WMM if the band is set to B, G, or B+G. STEP 6 In the Encryption field, choose the type of security for the WBPN: • None-Security is not enabled on your wireless device. (Not recommended.) • WEP-Wired Equivalent Privacy encryption. (WEP is a weak form of encryption and is not recommended.) If you choose WEP, choose the type of authentication (Open System, Shared Key, or Auto). In the Key Length field, choose the length of the encryption bit. 128-bit encryption is more secure Cisco WBPN User Guide 25
