Telecoms company TIM says it has achieved a global first with one gigabit LTE speed delivered on live network-based on licensed assisted access.
During a demonstration in Milan, the company showed a download speed on live network up to 1Gbps, thanks to the evolution of its 4.5G network based on LAA (Licensed Assisted Access) technology in conjunction with Ericsson, Qualcomm and Asus.
This new world record is being hailed as a major step forward on the road to 5G.
The achievement was made possible in conjunction with Ericsson, Qualcomm Technologies Inc. and Asus, by making available – in addition to the use of advanced 4×4 MIMO and higher-order modulation (256QAM DL) already implemented in TIM’s 4.5G network – the LAA technology that aggregates LTE licensed frequencies with unlicensed 5GHz spectrum.
This 4.5G technology coexists with Wi-Fi on the 5GHz band and covers hot spot locations (shops, stadiums, malls, public squares, parks, etc.) and will be progressively deployed by TIM using small cells; low power radio antennas that can optimise radio coverage in crowded areas minimising visual and environmental impacts. 1Gbps downlink will be commercially available starting in September in the hot spots in Milan and Turin and will then be extended to other cities in Italy.
For this showcase on a live network TIM used the new Asus smartphone powered by the Qualcomm Snapdragon 835 with LTE X16 integrated modem and LTE-Licensed Assisted Access network technology by Ericsson.
After launching the first 4.5G network in Europe in December, TIM has recently upgraded its network, ensuring 700 Mbps download speeds in 11 cities including Milan, Turin, Naples, Rome, Palermo, Taormina and Giardini di Naxos. In addition, all TIM customers with a compatible mobile device can now access uplink speeds up to 75Mbps across the entire LTE network.
In addition, from September TIM will increase the upload speed of its 4.5G network to 130Mbps in 1,117 municipalities, using uplink Carrier Aggregation in addition to the already available higher modulation (64QAM UL). These technologies allow to aggregate two different frequency bands for the same data connection from the terminal to the network.
