Snapdragon 855: Up to 2 Gbps via LTE and additional 5G modem

Chipset maker Qualcomm is again proving to be an innovator in mobile broadband and is using a dual-modem solution for its upcoming Snapdragon 855 platform. The SoC will come up with an LTE modem (Snapdragon X24) and a 5G counterpart (Snapdragon X50) at the same time. There is a further tempo boost in terms of 4G connectivity up to 2 Gbit / s.

What is Snapdragon 855
The Snapdragon 845 SoC is the successor to 2017’s Snapdragon 835. It is made on Samsung’s second-generation 10LPP process, a refined version of 10LPE used for the 835, but according to a recent report, TSMC will be making the 7nm (FinFET) chips for the Snapdragon 855 SoC. Samsung recently announced that is working on 7LPP (Low Power Plus) with EUV (extreme ultra violet) lithography technology for smart phones that is targeted for initial production in the second half of 2018.
The same report said that Qualcomm is going with TSMC since it uses normal steppers while Samsung is going with 7nm EUV lithography tech which is riskier, and might not be ready on time.

Snapdragon 855 comes with modem twin pack
Qualcomm’s roadmap is easy to understand – towards the end of the year, a new high-end chipset will be presented, which will be available in the spring of the following year. This is what happened with the Snapdragon 845 recently , for example, the current SoC is used in the new Sony smartphones Xperia XZ2 (Compact / Premium). Not until 2019 will the Qualcomm Snapdragon 855 chipset reach the market, but some details are already known.

The Californian SoC professional will rely on the so-called fusion technology. The method connects an external 5G modem to an internal LTE modem of the chipset. The wireless modules are the Snapdragon X24 (LTE) and Snapdragon X50 (5G) products introduced in February 2018. The local network operators should get a tooth in the 4G expansion, if they want to use up to the release of the Snapdragon 855 the modem almost. Finally, the Snapdragon X24 boosts up to 2 Gbps. Currently , Vodafone offers up to 1 Gbit / s in four cities , the networks of Telekom and Telefónica reach a maximum of 300 Mbit / s and 255 Mbit / s respectively.

Low energy consumption despite two modems
Does not an additional externally connected radio module pull heavily on the battery? In fact, the power consumption would increase, but Qualcomm has already found a solution for this. The Snapdragon 855 chipset is manufactured in a 7nm process, which makes the SoC space-saving and lowers power consumption. Incidentally, the Snapdragon X50 5G modem will go a long way in terms of maximum bandwidth. Up to 5 Gbit / s can be achieved in the download. When the first smart phones with Snapdragon 855 appear in about a year, we will get highly-secure mobile devices. Before then, the fastest mobile device could only support 1Gbps, both of them are made with Qualcomm’s chipset, like Huawei E5788 and Netgear M1. You could experience the speed now.
