Samsung’s New Cat.18 6CA LTE Smartphone Modem Supports Up To 1.2Gbps Download Speeds

Samsung has announced its Cat.18 6CA-supported LTE smartphone modem for its next generation Galaxy S9 and other mobile devices which is the first of its kind in the industry to get. Here are the details.

It’s said and informed that the newly announced Samsung’s Cat.18 is a new LTE modem technology developed for its next mobile processor that will support 6CA (carrier aggregation). The Cat.18 6CA LTE technology will offer a maximum download speed of 1.2Gbps (gigabits per second), compared to Cat.16 LTE modem with 1Gbps downlink speed in the Samsung Exynos 9 Series (8895) chips that powers the Samsung Galaxy S8 series of phones.

In terms of talent and experiences, Samsung’s latest LTE modem supports faster-than-fiber speeds, too. If all starts (and LTE towers) align, you’ll get 1.2Gbps with Samsung’s latest chipset. That’s 20 percent faster than the 1 Gbps 5CA (five carrier aggregation) modem that Samsung put in its Exynos 8895 chips for the Galaxy S8.

If you are in the market for the Galaxy S9 next year, it could have a modem that’s faster than your home (ActFiber) connection. Samsung has today unveiled a co-called 6CA modem that can handle download speeds as high as 1.2 gigabits, fast enough to download a full length HD movie in 10 seconds. OMG!

In a press release note. Samsung says its Cat.18 6CA LTE mode technology will allow it to access up to six LTE bands at once. Also mentions that its new LTE model will support 4×4 MIMO (Multiple-Input, Multiple-Output) and a higher-order 256 QAM (Quadrature amplitude modulation) scheme. Mass production of this new processor from Samsung, with the new LTE modem, is expected to begin sometime late in 2017. Likely means that the Galaxy S9 will be the first and foremost to get that processor and modem support for international markets.

As a reminder, this is still LTE Advanced and not the 5G that networks in the US, Europe and elsewhere are building out now. Rather to achieve such speeds, mobile operators allow the chips to grab multiple LTE frequencies, and everything like 800Mhz and 1.8GHz, and combine them. While Samsung worked with a Japanese company that measures cellphone network speeds, Anritsu. A new system that combines up to six frequencies rather than five and will offer more stable data transfers.

The theoretical 1.2Gbps speed is nice, but in real life you’d be lucky to get a fraction of that in North America. Most carriers are only aggregating three LTE channels at best, and network congestion prevents the amazing speeds we see in testing. In fact, Spring recently promised four carrier aggregation and reached 330Mbps on a single channel via “massive MIMO” trails with Samsung.

By utilizing enhanced Licensed-Assisted Access (eLAA) that can aggregate licensed and unlicensed spectra, this technology also allows telecommunications operators to make full use of their new equipment. New Samsung mobile processors with Cat.18 6CA LTE modem will go on mass production by the end of the year, and there are chances we might see it in the Galaxy Note 8 – all set to be announced on August 23. But again, a new Exynos 9 Series SoC with the new LTE technology will likely power next year’s Galaxy S9, after all. Thought to be called the Exynos 9810, though US buyers will probably get a Qualcomm Snapdragon chip.
