Engine (EPE). Location service capability is provided by the EPE 4.0 using Ekahau
Location Protocol (ELP). See Ekahau user documentation for more information.
RTLS [Enable/Disable] – the RTLS is disabled by default. Press NavOK to toggle to the
alternate setting. When RTLS is enabled, the handset will display the RTLS icon
the ring indicator icon location.
The ring indicator icon will take precedence over the RTLS icon, i.e. the new icon will
not be visible while the handset is ringing. When ringing has ceased and the ring
indicator becomes inactive, the RTLS icon will again appear (regardless of hook state).
Transmit Interval – allows selection of 15 seconds, 30 seconds, 1 minute, 5 minutes, or
10 minutes for maximum time between transmit intervals. Default transmit interval is
10 minutes. Press NavOK to select the desired transmit interval.
To optimize battery life, the interval between sending out ELP updates will vary

based on handset state. It is expected that ELP updates will occur at most
every two to six seconds and at least every few minutes. If improved tracking
capability is desired, set the transmit interval for a shorter time between ELP
updates. Increasing the frequency of transmissions will decrease battery life.
Location Server IP – allows the user to statically enter the IP address of the EPE. Enter
the IP address and press NavOK to save.
Ekahau clients are not expected to find the EPE automatically. Regardless of

the handset's selection of DHCP or static IP, the EPE IP address must be
statically entered in the Ekahau admin menus or HAT.
ELP Port -- Allows the user to select the port number which ELP updates get sent to at
the Location Server IP address. It must match the value configured in the Ekahau
Positioning Engine for proper functionality. The ELP port number must be greater than
zero and less than 65536. Default is 8552. Enter the port number and press NavOK to
save.
Network Config
IP Address
There are two modes in which the Wireless IP Telephone can operate – DHCP enabled or
Static IP. Select the mode for operation from the IP Address menu:
* Use DHCP – will use Dynamic Host Configuration Protocol to assign an IP Address
each time the Wireless IP Telephone is turned on. If DHCP is enabled, the Wireless IP
Telephone also receives all other IP Address configurations from the DHCP server.
Static IP – allows you to manually set a fixed IP Address. If selected, the Wireless IP
Telephone will prompt for the IP Addresses of each configurable network component.
When entering addresses, enter the digits only, including leading zeroes. No periods
are required.
Regardless of the mode in which the Wireless IP Telephone is operating, the following
components must be configured:
