Movistar Argentina and Swedish vendor Ericsson have announced that they have achieved downlink transmission speeds of up to 288Mbps in a Buenos Aires-based LTE-Advanced (LTE-A) trial. The tests, which aggregated spectrum in the 700MHz and 2100MHz/1700MHz AWS bands, took place at Telefonica’s laboratory in the capital, using commercially available terminals. The maximum download speed previously achieved over Movistar’s 4G networks was 140Mbps.
According to TeleGeography’s GlobalComms Database, Movistar’s LTE network went live in December 2014, one month after the Spanish-owned cellco won a nationwide concession pairing frequencies in the 1710MHz-1720MHz and 2110MHz-2120MHz bands. The network, which Movistar claims is the country’s most expansive, currently comprises 3,000 base transceiver stations (BTS), giving the cellco coverage of 68% of the country’s population. Service is said to be available in more than 380 locations, including all 23 provincial capitals and the Ciudad Autonoma de Buenos Aires. 52% of Movistar’s 4G traffic is generated in Buenos Aires, the company noted earlier this year.
