The exhibition MWC 2016 in Shanghai, Qualcomm announced the expansion of the ecosystem of chipsets with support Cat-M1 and Cat-NB1, and also showed a prototype of 5G New Radio / NR, capable of providing mobile connection speed at a speed of several gigabits per second, which is one of the criteria in the development of the fifth-generation networks. In addition, the company is confident that the new LTE standards will help reduce the complexity of the Internet of Things infrastructure and improve the coverage, which will allow you to connect devices depths buildings and other hard to reach places where the signal is usually fails. At the same time on the market in large volume began to appear solutions to support the new standards. Already, more than a hundred devices equipped with chipsets MDM9x07 series modem Qualcomm Snapdragon X5 LTE and MDM9207-1 modem for Internet of Things.

The modem Snapdragon X5 LTE supports data transfer rates of up to 150 Mbit / s, while the model MDM9207-1 operates at speeds up to 10 Mbit / s, but at the same time has a power saving mode and can run on two AA batteries type up to 10 years. They are compatible with the major cellular standards, are compatible with the Linux operating system, equipped with processors based on the ARM Cortex A7, and have built-in technology Qualcomm VIVE 802.11ac Wi-Fi with the MU-MIMO, Bluetooth 4.2, Bluetooth Low Energy and GNSS-geolocation. This platform scale the full software method.

Qualcomm представляет новые технологии, которые перерастут в 5G

These modems can be used in “smart” meters, buildings, security systems, industrial automation and process control , POS-terminals, tracking goods telematics in healthcare, lighting, after-sales service, and many more where. According to the report GSA Association, more than 20 mobile operators from around the world are ready for the introduction of NB-IoT standards. The main advantages of this solution is:

  • use of existing infrastructure networks LTE;
  • possibility of the standard scale of tens of kbit / s to Gigabit speeds LTE;
  • work in the existing LTE networks and the use of the available frequency spectrum and services;
  • use frequencies licensed spectrum;
  • robust security and authentication technology

The forecast is that the NB-IoT will continue his own. development and will “grow into” the new features, such as multicast-broadcast and geopositioning, after the 13th, LTE release that in the future grow into Narrowband 5G IoT technology.

3GPP consortium is also working on the specification of a unified wireless interface 5G New Radio. This standard can support multiple sensors with low power consumption, as well as for devices and applications with ultra-low latency and high availability connectivity, such as industrial automation, robotics and drones.

Presented by Qualcomm prototype 5G New Radio operates in the spectrum to 6 GHz and transmits data at speeds up to several gigabits per second in a low delay. This prototype is to contribute to the acceleration of the standardization of the new 5G NR 3GPP consortium OFDM-interface. Qualcomm plans to conduct testing 5G NR with mobile operators and network equipment manufacturers. Demonstrated at the show prototype operates in 28 GHz range and provides a reliable broadband connection in environments where the signal from the base station passes with difficulty.

presented the prototype of 5G NR consists of a base station and terminal equipment. It supports frequencies above 100 MHz is capable of providing the speed and level of several gigabits per second. Wherein the delay time is substantially lower than in the existing LTE network. Testing conducted 5G NR opportunities for the development of the 14th version of LTE by 3GPP and will continue at the stage of development of the 15th version of the standard
