Ec/Io

From ShadoWiki

The ratio of received pilot energy, Ec, to total received energy or the total power spectral density, Io. Ec/Io is expressed in dB. The symbol NoT is sometimes used to denote Io. Ec/Io is a CDMA only reading and is somtimes known as PILOT_STRENTH.

A ratio of 10db to 14db is normal, numbers going higher than that is progressively worse to 63db, where power readings are unmeasureable.
