SSID: The SSID for the WLAN.


Cipher: The encryption type mode used by the WLAN. (Old WEP Styles in 64 and 128 bit versions, obsoleted Cisco CKIP, WPA - TKIP and WPA2-AES-CCMP).
WEP Key index: The WEP key index (1-4) used when transmitting data.
WEP Key: WEP key for the WLAN.

Security Mode

Association Mode: The association mode the WLAN (None, WPA or WPA2).
Authentication Mode: The authentication mode the WLAN (EAP - without dynamic key exchange, LEAP - with and without dymanic key exchage, and PEAP-MSCHAPv2 with dymanic key exchange).
Passphrase: The passphrase used for WPA-PSK.
User: The user name used for EAP (PEAP, LEAP) authentication.
Password: The password used for EAP (PEAP, LEAP) authentication.

Power Management

Power Managament options increase the battery life (talk-time and standby-time) of IP72 handset.

For a longer discussion regarding this subject, see

There are three powersave modes:

  • Active - No powersave at all, the WLAN chip is permanently active sending and receiveing packets
  • Poll - The WLAN chip may doze between beacons (e.g. 100ms every beacon) and check the TIM (Traffic Indiaction Map) in beacon packet. If the TIM indicates buffered packets by acces point, a PowerSavePoll is issued for each buffered packet, which is trasmitted to terminal.
  • UAPSD (Unscheduled Automatic Power Save Delivery) - trigger and delivery mode: the WLAN chip may doze between packet s(e.g. 30ms), when awakend, it sends a packet (regardless of beacon delivery and TIM carried within beacon). Upon receival of the packet, the access points knows that the terminal is awake and transmits the buffered packets within the TXOP (Transmit Opportunity) time window.

Powermodes define the doze (sleep) time between beacons:

  • Active - No doze at all.
  • Short doze - Wake up on every beacon (every TIM).
  • Long doze - Wake up on every beacon carrying a DTIM (Delivery TIM).

Power Save: Power save options for WLAN:

Use UAPSD if possible, POLL if unsupported and Active as last resort or testing purposes only.

Powermode (idle): Powermode in idle mode:

Use long doze if possible, and active for testing purposes only.

Powermode (call): Powermode in call mode:

Use long doze if possible, and active fo testing purposes, or as last resort to increase voice quality.

Regulatory Domain

Domain: Regulatory domain assigning frequencies in the country where the IP72 is used.

In 802.11d (World mode), the Acess Point informs the IP72 terminal which frequencies and channels are legal and usable. This is the most conveniant option, but if the access point doesn't support this feature, the regulatory domain must be set manually as described below.

US and Canada use channels 1 to 11.

ETSI (Europe excluding Spain and France) uses channels 1 to 13.

Spain uses channels 10 to 11.

France uses channels 10 to 11.


RSSI Threshold: RSSI Threshold when to start roaming. Valid range is between -80 dbM and -60 dBm. Note that this option only effects the idle mode. During call mode, the handset scans periodically for better RSSI, and roams on 6 dBm difference. This is an advanced option, which one may never have to use.

It make sense to increase the threshold in office bulding with lots of walls and corners where the signal strength decreases very fast due to fast movements around corners. In this case -65dBm could be used.

Decreasing the threshold is very unlikely.

Channel Mask: Channel bitmask. Provide here a HEX number for channels that should be scanned by handset. Is used to increase roaming performance. If, for example, the WLAN infrastructure only uses channels 1,6 and 11, the channel mask 0x421 could be used.

However, this is an advanced option, which one may never have to use.


0x1FFF = 1111111111111  scan all 13 Channels
0x7FF  = 0011111111111  scan all 11 Channels
0x421  = 0010000100001  scan only 11,6,1
0x1020 = 1000000100000  scan only 13 and 6

If you have access to a Unix shell, here a fast way to calculate the values for e.g. 11,6,1, note that ones shifts the 1st bit 10,5,0 positions:

printf %x $(((1<<0)+(1<<5)+(1<<10)))
