The deployment of VoLTE and the refarming of PCS spectrum (as well as the deployment of the AWS spectrum) are key initiatives for the U.S. wireless industry that could potentially result in $28 billion to $30 billion in business for American Tower over the next few years, according to the company's CEO.
Top U.S. Cellular executives said that the company currently has enough spectrum and resources to meet its customers' demands for mobile connections. However, company executives said at an investor event that the company might purchase some spectrum in the FCC's upcoming incentive auction of TV broadcasters' 600 MHz spectrum.
T-Mobile's LTE network expanded geographically by nearly 250 percent in 2015, company executives boasted, and now covers 304 POPs. CTO Neville Ray credited most of that expansion to T-Mobile's used of 700 MHz A block spectrum, which it has deployed to a population of 185 million POPs.
Nearly 40 percent of voice calls on T-Mobile's network are transmitted via Voice over LTE (VoLTE), illustrating how aggressively the carrier is pursuing the technology.
The number of voice-over-LTE (VoLTE) deployments has reached 40 worldwide, as mobile operators continue to focus on improving the quality of voice services by offering high-definition (HD) voice on 2G/3G and 4G networks.
Polkomtel is gearing up to become the first mobile operator in Poland to offer Wi-Fi calling after it teamed up with Nokia Networks to trial the vendor's voice-over-Wi-Fi (VoWi-Fi) technology.
Bouygues Telecom is offering voice-over-LTE (VoLTE) services to some of its clients ahead of a wider launch in 2016.
For a long time, it was all about data, but now mobile voice is firmly back in operators' sights as they seek to retrieve control of what was their former sole domain. Our recent special report on Wi-Fi calling, for example, explored some of the approaches, from dialler-integrated Wi-Fi calling through to downloadable apps such as Three InTouch and Telefonica's TU Go service.
Smile Telecom said it is the first mobile operator to offer voice-over-LTE (VoLTE) in East Africa after it launched the 4G voice service in three cities in Uganda.
In the UK, the next generation of Wi-Fi calling-- where the service is embedded in the smartphone and accessed via the normal phone dialer-- is offering operators a way to take back control by enabling them to provide voice services in areas where they have little or no coverage due to poor signal strength.
