  • Page 7: Overview

    OVERVIEW The WP820 is a portable Wi-Fi phone designed to suit a variety of enterprises and vertical market applications, including retail, logistics, medical and security. This powerful, portable Wi-Fi phone comes equipped with integrated dual-band 802.11a/b/g/n Wi-Fi support, advanced antenna design and roaming support, and integrated Bluetooth for pairing with headsets and mobile devices.

    WP820, the device will try to look for a nearby AP with better RSSI. To avoid switchover back and forth due to unstable RSSI, the WP820 will only switch over when the new AP’s RSSI is at least 8 dB higher than the currently connected AP.

  • Page 9: Important Wi-Fi Parameters On Ap

    During deployment, the cell edge for each AP should be designed to -67dBm and there should be 20% - 30% overlap between adjacent APs at that signal level. Otherwise, WP820 might encounter packet loss or blind area at the cell edge and it cannot hold the signal long enough to complete seamless switchover. To ensure seamless roaming, it’s recommended that WP820 can always receive RSSI -67dBm or higher from the access point.

    IP Precedence, Diff-Serv or MPLS. The default setting is 46 which is equivalent to the DSCP name constant CS6. WP820 will convert the QoS value to the corresponding WMM value/level so the packets can be differentiated and handled properly by other network devices.
