NEC Corporation has announced that it has successfully carried out laboratory trials of Long Term Evolution (LTE) technology with the Argentine unit of Spanish telecoms group Telefonica. To carry out the trials, which took place between February and March 2010, NEC provided Telefonica de Argentina (TdA) with a total LTE network system, comprising core network systems and wireless base stations. According to NEC, approximately 100 test items requested by Telefonica were achieved while under a 20MHz bandwidth, including a maximum throughput of 145Mbps while connecting with a simulator device. The trials also achieved a maximum throughput of 95Mbps using an actual LTE terminal. As previously reported by CommsUpdate, Telefonica reached an agreement with six LTE technology providers in September 2009 to launch pilot schemes in six different countries with a view to rolling out commercial 4G services in the regions where it operates. The countries selected for testing were Spain, the UK, Germany, the Czech Republic, Brazil and Argentina, while the vendors chosen were Alcatel-Lucent, Ericsson, Huawei, NEC, Nokia Siemens Network (NSN) and ZTE.
