Composed of 通話 (phone call, communication) and 圏 (sphere, range, zone). A telecommunications term that is most familiar to ordinary users through the phrase 通話圏外 (out of the coverage area) displayed on mobile phones.
USAGE:
通話圏 itself is less commonly seen standalone than as part of the compounds 通話圏内 (in the coverage area) and 通話圏外 (out of the coverage area). These fixed pairs are the practical forms learners will encounter most often.
