Wireless companies, following the lead of cable companies, have spent the past couple of years expanding their Wi-Fi networks, notes a new article. This is a big turnaround from previous years, when it was commonly assumed that wireless operators considered Wi-Fi a threat to their core business. Today, however, Wi-Fi is being embraced by these same companies, many of which see new technologies such as Wi-Fi calling becoming an important segment of their service.

Wireless companies are interested in Wi-Fi calling because it’s less expensive for their customers, particularly in situations involving international roaming. Additionally, using Wi-Fi calling obviates the need for building extra infrastructure, such as new base stations, etc. AT&T, Sprint, and Google are just some of the big players who are putting Wi-Fi at the forefront of their expanding networks.
