Lithuanian mobile operator Omnitel has enabled voice-over-LTE (VoLTE) technology over its 4G network. The company said that VoLTE was implemented in the cloud-based IP Multimedia Subsystem (IMS) platform, which combines mobile and fixed-line communication technologies. Omnitel technology manager Andrew Semeskevicius said: ‘With this technology, customers can significantly improve the experience of using mobile communications – during the call they can continue surfing the 4G network, the voice can be heard more clearly and naturally, with increased voice service reliability.’ In order to benefit from the new service, potential users need to implement a software update to their 4G-enabled devices; when calling to/from a device that does not support VoLTE, the voice call will be transmitted over the 2G/3G networks, Omnitel said.
TeleGeography notes that Omnitel launched commercial LTE services in Vilnius, Kaunas, Klaipeda, Siauliai and Panevezys in April 2011, with the LTE footprint since expanded to 99% of the population. Omnitel began offering LTE-Advanced (LTE-A) services in December 2014 in Vilnius, Kaunas, Klaipeda, Siauliai and Panevezys, supporting maximum download speeds of up to 330Mbps, while LTE-A Pro – capable of delivering downlink of up to 1Gbps – was trialled in February 2016, achieving maximum download speeds of 750Mbps.
