Over 30 per cent of operators are investing in LTE-A system deployments, with the commercialisation of carrier aggregation the first feature to be exploited.
T-Mobile US announced it launched new messaging services based on Rich Communication Services (RCS) technology. The carrier said the service will be called Advanced Messaging and will be available initially on the new Samsung Galaxy Grand Prime smartphone. The carrier said it will soon update the Samsung Galaxy S6 and S5 to support the technology as well.
Verizon Wireless, AT&T Mobility and T-Mobile US' implementations of Voice over LTE demonstrate significant improvements in voice quality over legacy circuit-switched voice, with Verizon leading the way in terms of call quality, according to a new benchmarking test by network testing firm P3 Communications.
Swisscom said it is the first operator in Switzerland to launch voice over LTE (VoLTE) and that it will add a Wi-Fi calling feature during the summer months.
U.S. Cellular is trialing Voice over LTE technology in three markets right now and expects to turn the service on commercially sometime later this year, according to CEO Ken Meyers.
In the past seven months, Verizon Wireless said its customers have placed more than 1 billion VoLTE calls, talking for more than 3 billion minutes.
Voice over LTE (VoLTE) and LTE Advanced (LTE-A) are among the hottest mobile network trends right now for operators, and deployments are rising across the globe.
EE has launched Wi-Fi calling services designed to enable users to make calls and send texts via their home or office Wi-Fi networks where mobile coverage is poor.
AT&T Mobility said it will need to wait until it deploys Voice over LTE nationwide to support CDMA voice roaming on its 700 MHz spectrum.
U.S. Cellular plans to cover essentially its entire customer base with LTE by the end of the year, hoping that expanded access to faster mobile broadband speeds will help its subscriber numbers and churn.
