15 Apr 2015

Russian wireless giant Mobile TeleSystems (MTS) is said to have conducted a successful test of tri-band Carrier Aggregation (CA) technology in the Republic of Bashkortostan. According to an unverified report by ComNews, the trial utilised frequencies in the 800MHz, 1800MHz and 2600MHz bands, and saw MTS achieve downlink transmission speeds of 260Mbps. ComNews notes that Swedish vendor Ericsson and US semiconductor firm Qualcomm oversaw the CA tests.

Meanwhile, a separate unconfirmed report from ComNews claims that MTS rival Vimpelcom (Beeline) has also conducted a successful tri-band CA trial recently, this time in conjunction with Huawei of China and Qualcomm, which utilised its Snapdragon platform. The trial also utilised 800MHz, 1800MHz and 2600MHz frequencies, and saw Vimpelcom notch download speeds of up to 250Mbps. The tests reportedly took place under laboratory conditions, although MTS and Beeline have not yet confirmed them.
