Qualcomm Snapdragon 845 chipset will Be Available in 2018

Qualcomm has announced the Snapdragon 845, a new high-end chipset for smartphones, tablets, notebooks and other mobile devices. The successor to the Snapdragon 835 comes with improved processor performance, a faster modem and a better graphics unit. It is expected that the Snapdragon 845 will be used in various flagship smartphones with Android OS from 2018, for example, in devices such as the LG G7 or the Samsung Galaxy S9.

Octa-core processor

The heart of the Qualcomm Snapdragon 845 is an octa-core processor. This consists of two quad-core processors, each with up to 1.8 GHz or 2.8 GHz clock power. The associated main memory is clocked up to 1866 MHz (Dual Channel LPDDR4x). The performance should be well above that of the predecessor Snapdragon 835, so the chipset now supports, for example, the encoding or decoding of videos with 2160p resolution at 60 fps and 10-bit color depth in H.265 format.

 

LTE Cat18: Modem for up to 1.2 GBit/s

Of course, the Qualcomm Snapdragon 845 also has an integrated modem. While the predecessor Snapdragon X16 modem with LTE Cat16 installed, the Snapdragon 845 is now the Snapdragon X20 modem with LTE Cat18 on board. The maximum LTE speed is 1.2 Gigabit per second in the downlink and 150 MBit/s in the uplink (UL Cat13). The downlink supports 5CC CA, which is a fivefold channel bundling. In addition, the modem can downlink the 256QAM modulation as well as 4 × 4 MIMO on up to three carriers simultaneously. A maximum of 2CC carrier aggregation is possible in the uplink, and 64QAM modulation is also available here.

 

Of course, the speeds that can be reached on the end device depend not only on the modem but also on the mobile network. In many countries, few providers currently offer 1.2 GBit/s in its LTE network.

Snapdragon 845: more features

Other features of the Qualcomm Snapdragon 845 include display resolutions of up to 4K Ultra HD, both on the integrated display and on a possible external display. As a graphics processor, an Adreno 630 is used, compared to the Adreno 540 from the Snapdragon 835. In addition, the chipset offers native support for biometric authentication as well as secure mobile payment.

 

Vodafone Launches Gigabit LTE with 4 × 4 MIMO

Vodafone is the first German mobile network operator to announce the launch of LTE with gigabit speed and promises the launch of the first smartphone with Gigabit LTE modem in the market. Up to now, data rates of up to 500 MBit/s were possible in the Vodafone network, the speed is now doubled with the new 4 × 4 MIMO antenna technology. Gigabit LTE is now available in Berlin, Hamburg, Hanover and Düsseldorf, further cities are to follow according to Vodafone.

Gigabit LTE: new network technology for faster speed

Vodafone combines several different technologies to achieve gigabit data rates in the LTE network. Thus, on the one hand, Carrier Aggregation (Channel bundling) is used to bundle different frequency ranges and thus make a larger radio spectrum available to the terminal. Vodafone currently uses 3CC (3CA) with band 3, 7 and 20 (800, 1800 and 2600 MHz), but in the future LTE will also be used on 2100 MHz (band 1), so that 4CC CA and 4CA it is possible. The second technology for increasing the speed in the downlink is the 256QAM modulation. Last but not least, the 4 × 4 MIMO antenna technology is now supported at the locations with Gigabit LTE, which means that it is sent and received twice as many antennas as before. To date, 2 × 2 MIMO antennas have been common.

Gigabit LTE is only available in a few locations

According to Vodafone, the first cities with Gigabit LTE supply are Düsseldorf, Hamburg, Hannover and Berlin, more cities to follow. However, the high speed is not available at every transmitter; rather Gigabit LTE will only be developed in places with very high data traffic, also to increase the capacity in the network. A comprehensive expansion is not worthwhile for the operator, since for Gigabit LTE a very high transmitter density is necessary.

Gigabit LTE can only be used with a new terminal

If you want to use the full Gigabit in the download also on the smartphone, you need a new device, which can support at least LTE category 16 (LTE Cat16). In addition, the smartphone must possess 4 × 4 MIMO antenna technology, as well as 256QAM modulation and at least three-fold carrier aggregation. If one of the features is not supported, then the speed drops dramatically: 256QAM modulation increases the speed compared to the 64QAM modulation by 33%, 4 × 4 MIMO increases the speed by 50% compared to 2 × 2 MIMO. Here now, there is Netgear Nighthawk M1 MR1100 Gigabit LTE Router is available in Australia for network provider Telstra, but you can get unlocked Netgear Nighthawk M1 from www.4gltemall.com so as to use in Germany and other European countries. It’s a Gigabit mobile hotspot for a group of people. If you want to use the stationary router for the Vodafone Gigabit LTE network, the lastest Huawei B618s-22d 4G Router is also recommended.

And Huawei had recently released the new flagship smartphone Huawei Mate 10 and Mate 10 Pro would support the Gigabit LTE networks. These are the more latest wireless terminals for the LTE advanced pro networks. We suppose there will be more and more gadgets for the LTE-A pro. And we will keep updating on www.4gltemall.com/blog.
