Radio signal information overview

Reconeyez cloud now offers improved radio signal information to the users. For all detectors/sirens/keypads the 2.4 GHz zigbee signal quality with the bridge is displayed. For the bridge units the mobile signal quality of the bridge itself is displayed.

Radio signal in the table view

Devices menu table view shows a summary of the radio information in the Signal column using a simple 4 bar signal icon (poor-OK-good-very good). Hovering over the Signal column will display more detailed radio infromation - radio routes showing the number of hops between the device and it’s bridge; and the time when radio info was last updated. The simplified 4 bar signal indicator is calculated based on the more technical radio signal parameters that can be viewed in the device view. If any of these parameters is outside of the acceptable range, then the whole radio link is displayed having reduced quality.

Radio signal in the device view

Device view shows more detailed  2.4 Ghz signal information under the new Analytics tab. Route and multihop info related to the chosen device is displayed in more detail, allowing user to click on the device names to see the quality of each radio hop separately.

In addition the device view shows a more detailed 2.4 GHz radio signal history graph with the following advanced radio parameters’ history displayed.
1) RSSI - Received Signal Strength Indicator - usually indicating link distance or obsticles in dBM (< 70 dBm = excellent)
2) LQI - Link Quality Index - usually indicating radio interference in the area or obsticles (100=excellent)
3) ETX - Expected Transmission Count - indicates number of packet repetition (10 = no repetition)

FROM values indicate 2.4 GHz signal viewed FROM the detector/siren/keypad perspective and TO values indicate 2.4 GHz signal info viewed from the bridge perspective (TO the detector/siren/keypad). This helps to distinguish with more precision the source of radio interference or device antenna damage. As in most cases the radio links FROM detector to the bridge are more informational, then by default only FROM values are enabled in this graph for the sake of simplicity. This shows the signal quality from the detector to the bridge - the direction in which most of the data (eg. alarm photos) is travelling.

Radio signal in the bridge view

The bridge view shows more detailed mobile signal quality info. Mobile signal quality is calculated based on the following two parameters. If either of them is below threshold, then the 4 bar signal icon displays worse signal.
1) mobile RSSI - Received Signal Strength Indicator - mobile signal strength in dBm (< 70 dBm = excellent)
2) BER - Bit Error Rate - mobile packet repetition rate in percentage (0% = excellent)
