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.

Telecommunications testing company Spirent announced this week a new operator analytics solution, the InTouch Customer and Network Analytics (CNA) solution. The technology is an evolution of Spirent's existing InTouch CNA platform and is compatible with 2, 3 and 4G systems.
U.S. Cellular is currently testing VoLTE in three markets but the company has not set a timeframe for commercial deployment of the service. U.S. Cellular President and CEO Ken Meyers told investors at the Wells Fargo Securities Technology, Media & Telecom conference that he expects VoLTE will have a multi-year rollout similar to the company's LTE service, which it deployed over a four-year time period.
The number of voice over LTE (VoLTE) connections is expected to reach 2 billion by 2020, rising from an estimated 123 million in 2015.
Here's an idea for a new operator tagline: "The most consistent wireless network." OK, so I won't win a CLIO. But as banal and unlikely to be adopted as that adage sounds, it's going to be the most important measure of a user's wireless network experience going forward. What do I mean by 'most consistent'? Well, when you think about it, when the cellular network is at its best, data performance is about as good we need it to be: 20 Mbps (and as much as 50 Mbps), latency around 50 ms, and even dramatically improved voice quality when the stars line up for a rockin' VoLTE/HD Voice call.
EE said 4G customers now represent more than 52 per cent of its total mobile customer base, noting that it has doubled the number of 4G customers over the last 12 months.
Vodafone said it is the first mobile operator in Portugal to launch voice-over-LTE (VoLTE) services, offering improved voice quality and the ability to use voice and data services simultaneously over its 4G network.
