China’s ZTE Corporation has announced the signing of a deal with Swedish mobile operator Hi3G Access worth USD74 million to expand its 4G and 3G cellular infrastructure. Under the ‘strategic cooperation agreement’ ZTE says it will deploy several thousand UMTS/LTE TDD/LTE FDD base stations, as well as auxiliary microwave and data transmission equipment over the next three years. ‘We are very glad to ink the deal with Hi3G in Sweden where the two companies launched the world’s first multi-mode LTE network,’ said Huang Zheng, CEO of ZTE Sweden. ZTE’s ‘Uni-Ran’ solutions have been utilised to help Hi3G to integrate three modes and five frequencies into one network, with commercial operations launched at the end of 2011, under the claim of being Europe’s first large-scale LTE-based TDD network. Hi3G Sweden’s CTO Jorgen Askeroth said recently of the deployment: ‘Over the past twelve months, Hi3G Sweden and ZTE went all out to deploy the LTE network in Sweden. ZTE offers professional support and achieved the target commercial launch date of 15 December 2011. As of now, TDD performance is better than expected.’ TeleGeography’s GlobalComms Database says that via a March 2012 contract between the two companies, Hi3G’s existing 2600MHz LTE network (launched in December in Stockholm, Gothenburg and Malmo) is being expanded across southern Sweden using the 800MHz digital dividend frequency band.
