EC/IO: Difference between revisions

Revision as of 10:17, 2 October 2017

The EC/IO is a measure of the quality/cleanliness of the signal from the tower to the modem and indicates the signal-tonoise ratio (the ratio of the received/good energy to the interference/bad energy). It is measured in decibels (dB). In a perfect world, where there is no true interference, the interference level is equal to the noise level resulting in an EC/IO = 0 dB. Once the EC/IO is above ~ -7.0 dB, your connection is going to suffer. There are several factors that can contribute to a higher EC/IO value, including florescent lighting, electric motors, equipment, power supplies, bad/poor cabling, trees, hills, buildings, walls, shorted connectors, inaccurate antenna alignment, wrong antenna polarization, congestion at the tower, etc.

More information on EC/IO can be found in the 3G section of the Mobile Signal Strength Recommendations page.
