This tag is used to control the WLAN (RF) meter display. The meter may also be

controlled within the CETerm configuration, independent of the Signal tag. The

Signal tag will always override the internal configuration and will persist until

changed by another Signal tag. Within the CETerm configuration you can

specify the update interval and a notification when the strength falls below a

designated level.

Example

<html>

<head>

</head>

<body>

The RF meter should be visible.

...

</body>

</html>

3.20 SIGNALNAVIGATE

The SignalNavigate tag causes the specified JavaScript or URL to be invoked

with WLAN signal information on a regular interval. The interval can be specified

within a CETerm configuration dialog.

Syntax

http-equiv="SignalNavigate"

content="javascript:OnSignal('%s', '%s', '%s');"

<!- or ->

content="/signal.htm?strength=%s&ESSID=%s&MAC=%s"

Where the “%s” are replaced with (1) signal strength, (2) ESSID, and (3) the

MAC address of the device.

Comments

This tag will work with or without a visible WLAN signal meter. The strength

normally ranges from 0 to 100. The special strength value of -2 indicates that the

device is not associated with any access point. The special strength value of -1

indicates that the strength cannot be determined. If you use a URL for the

action, in most cases, the URL will navigate away from the current page rather

than repeatedly calling a JavaScript method.
