Swiss mobile provider Salt increased coverage of its 4G+ LTE-Advanced (LTE-A) network to more than 40% of the population by the end of May 2017, enabling users to access download speeds of up to 300Mbps. Further, the cellco deployed 4G technology to more than 88% of its macro antenna sites by the end of the month, adding that ‘tangible’ improvements had been made to coverage in several middle-sized cities, including Winterthur, Biel/Bienne and Thun. Salt added that, of the existing antenna sites upgraded with 4G technology in May, it had focused in particular on the Bernese Oberland region, with developments in Innertkirchen, Zweisimmen, Ried and Sonceboz. Commenting on the network boost, Salt said in a statement that: ‘Salt’s ongoing investment effort into coverage and capacity improvements is clearly yielding fruits. The rate at which our antenna sites are currently being upgraded will allow us to catch up the already-narrowing gap in terms of 4G availability fast.’
