Features That Accelerate Speed
A lot goes into making a cutting-edge LTE modem, but there are key ingredients that make those lightning fast speeds.
The first is bandwidth, which the Exynos 9810 addresses with an industry first modem featuring category 18 with 6CA (carrier aggregation) downlink, and 2CA uplink. Carrier aggregation takes different bands of frequencies and binds them together, so your phone can take the fastest one available. Think of it like a six-lane highway that your car can weave in and out depending on which has less traffic. The end results? More bandwidth and more speed for you.
The next ingredient is the Exynos 9810’s 4x4 MIMO (Multiple-Input, Multiple-Output) support, which increases the overall bitrate through transmission of four different data streams on four different antennas. For users, this translates to faster data throughput, more capacity, better reliability, and increased range so you won’t be dropping signals.
The Exynos 9810 also supports 256-QAM (Quadrature Amplitude Modulation), a measurement of how many bits of data per symbol can be transferred over the network. Each data bit is either a 1 or a 0. Support for 256-QAM means 8-bits of data per symbol can be transferred over the network. Remember that highway analogy? Think of it as though your data is now being transported in a big truck that can be hold more packages resulting in fewer trucks on the road while delivering the same amount of data. That means even users in areas of the network with the poorest signal quality will still see faster speeds since more bits of data can be transferred at one time.
The final ingredient for those ultra-fast LTE connections is the Exynos 9810’s support for Licensed Assisted Access (LAA), a carrier aggregation of LTE in the unlicensed spectrum with the licensed band. In addition, the Exynos 9810 supports enhanced Licensed Assisted Access (eLAA) that includes uplink operation for LAA.
The World Streamed Seamlessly
With gigabit speeds now possible, the Exynos 9810 is pushing the envelope of what consumers can do with their devices. There will be obvious improvements in quality, for example, streaming videos via Facebook Live in 4K will now be possible. A faster modem means that general browsing will be faster in heavily populated areas and connections will remain stable even during peak hours. But new horizons are also now within reach. Under ideal conditions the modem is capable of uploading a 300MB 4k video in just 30 seconds, while a full-length HD movie could be downloaded in just 10 seconds. Catching up on your favorite Netflix series during a boring commute will be a breeze.
Faster LTE also means cloud storage will act as a more meaningful extension of physical storage. Not only will uploading your videos, pictures, and other documents become a lot faster, accessing them at any time will also be more convenient, making it easier than ever to share all your documents quickly and seamlessly across your devices.
Thanks to the industry leading carrier aggregation and MIMO technology, faster and more reliable speeds are also possible at the cell edge. So not only will users notice improvements in the city, but connections in more rural areas will be faster and more reliable as well.
Moving the Needle for Mobile Experiences
While the Exynos 9810’s 1.2Gbps LTE modem is breaking new ground, and making new experiences possible, some of them won’t be possible until the networks catch up to the chip’s capabilities.
Augmented and virtual reality are tipped to be the next big breakthrough for mobile, and a faster LTE modem is critical to bringing data-heavy content to your phone. Not only does it allow for faster download speeds, the lower latency of LTE could allow for real-time VR content streaming to bring PC-quality VR experiences to mobile devices. What exactly new types of content the future will bring is uncertain, but one thing is for sure: it will be delivered by Exynos.
