Belgian fixed and mobile operator Proximus (formerly Belgacom) has said it plans to launch voice-over-LTE (VoLTE) services ‘later this year’ while adding that it has achieved speeds of up to 1.1Gbps during trials of ‘4.5G’ technology. The firm launched its 4G LTE network in 2012 and went on to add 225Mbps-capable LTE-Advanced (LTE-A) services in 20 cities in October 2015. The gigabit test speeds were achieved using carrier aggregation technology and spectrum in the 800MHz, 1800MHz, 2100MHz and 2600MHz bands. Proximus is the second largest of Belgium’s three mobile operators, claiming around 38% of the country’s 13.6 million subscribers at the end of 2015, according to TeleGeography’s GlobalComms Database.
Geert Standaert, Chief Technology Officer of Proximus, commented: ‘At Proximus, we believe the abundance of applications will require higher network performance in terms of speed, latency, and number of simultaneous connections. Just look at all the applications in advanced telemedicine, connected cars, or the all-pervasive media. In a world where everything will be connected, we want to continue offering the best mobile user experience, and we are delighted with the successful testing of 4.5G technology with our partner Huawei.’
