Samsung’s 6CA LTE modem achieves 1.2Gbps

Article By : Samsung

Samsung's new chip aggregates 6 carriers, boosting maximum downlink speeds to allow full-length HD movie downloads within 10 seconds.

South Korean semiconductor giant Samsung Electronics has developed an LTE modem technology for its mobile processors that supports 6CA (carrier aggregation).

Samsung said the new Cat.18 6CA-supported technology is capable of achieving 1.2Gbps maximum downlink speed, allowing smartphone users to download full-length movies in HD resolution within 10 seconds. Users will also be able to enjoy buffer-less video calls and mobile live-broadcasting, according to the company.

Carrier aggregation (CA) combines a given number of component carriers with various bandwidths, improving data transfer rates and network performance. By increasing the aggregation capability from the previous model’s five bandwidths to six, Samsung said the new LTE modem technology will offer faster yet more stable data transfers.

The technology also supports 4×4 MIMO (Multiple-Input, Multiple-Output) and higher-order 256 QAM (Quadrature amplitude modulation) scheme to maximise the data transfer rate. By utilising enhanced Licensed-Assisted Access (eLAA) that can aggregate licensed and unlicensed spectra, the technology also allows telecommunications operators to make fuller use of their equipment.

Samsung’s mobile processor adopting the new Cat.18 6CA-supported LTE modem technology is expected to be in mass production by the end of this year.
