The device is able to receive signals of a new generation.
Qualcomm first demonstrated the operation of the processor Snapdragon X50 in the networks of the fifth generation, and also showed a prototype 5G-smartphone, designed for testing next generation networks.
Qualcomm Technologies within the conference in 2017 Qualcomm 4G/5G Summit in Hong Kong conducted the first successful demonstration of its flagship processor Qualcomm Snapdragon X50 in the mobile network of the fifth generation 5G, and presented a prototype of its first 5G smartphone based on it.
Snapdragon X50 demonstrated not only the successful transmission of data at speeds more than 1 Gbps in the networks of several operators 5G, but also demonstrated practical work miniature mmWave antenna module in the frequency range of 28 GHz.
In addition to demonstrating the X50 Snapdragon chip, Qualcomm also showed a reference design of its first 5G mmWave mobile, designed for testing and optimization of mmWave 5G networks with the use of a real prototype in a mobile form factor.
According to Cristiano Amon (Cristiano Amon), Executive Vice President of Qualcomm Technologies, operators that deploy mmWave 5G network will be able to use the modem Snapdragon X50 5G for field testing in the early stages of implementation.
X50 Snapdragon mobile processor generation 5G
Mobile 5G-Snapdragon X50 was introduced in October last year. Qualcomm from the very beginning I positioned it as “the first modem for smartphones under the network generation 5G with data transfer speeds up to 5 Gbps”, designed to help OEM partners, the company is planning first to market commercial sales of the gadgets of the new generation of 5G.
Modem Snapdragon X50 5G can be used in mobile multi-mode 4G/5G gadgets and stationary wireless devices. Paired with a Qualcomm Snapdragon processor with an integrated Gigabit LTE, modem 5G X50 due to double connection can provide a stable redistribution of load.
Chipset Snapdragon X50 5G includes a transceiver SDR051 millimeter range (mmWave), and chip power control PMX50. Snapdragon X50 supports running in the 28 GHz range of the spectrum millimeter-wave (mmWave), as well as the technology of frequency division orthogonal multiplexing (OFDM) and multi-channel (Multiple-Input Multiple-Output, MIMO) antenna technology track radiation and adaptive beamforming to maintain a reliable and stable connection at distribution of a signal without line-of-sight (Non-Line-of-Sight, NLOS).
The Snapdragon X50 5G modem supports the frequency bands width up to 800 MHz and is designed for peak data transfer rates up to 5 Gbps.
In addition, during the presentation at the conference X50 2017 Qualcomm 4G/5G Summit it was also noted that the chipset also includes support for the frequency range of 600 MHz (Band 71), the operation of which, in particular, interested North American operator T-Mobile. Currently, the only smartphone that supports this range is LG V30, but by the end of 2017 and beginning 2018, the expected emergence of a greater number of compatible gadgets.
Prototype 5G-smartphone Qualcomm
Qualcomm does not produce smartphones, and no plans to deal with their issue in the foreseeable future. Presented by prototype 5G-smartphone created as a reference design that will allow for the testing of 5G networks, as well as help OEM developers to build their own smartphones based on the Snapdragon chipset X50 5G.
The reference model 5G-smartphone is made in the body thickness of only 9 mm. the Device is equipped with edge-to-edge display and dual main camera.
Field trials
5G modem Qualcomm provides a fivefold increase in data exchange speed compared to 4G modem, the power consumption logic generation 5G remains in the same range as that of the predecessors generation 4G.
Qualcomm plan eventually to achieve a real speed of 5G technology is about 5 GB/s. However, in practical tests in real 5G network yet managed to reach speeds of just over 1 GB/s thanks to the aggregation of two 100 MHz bands 5G. The developers emphasize that the modem Snapdragon X50 able to support aggregation of up to eight 100 MHz bands.
Especially for field testing of the Snapdragon chipset inside the X50 prototype 5G-smartphone, Qualcomm engineers have created a compact antenna range 28 GHz in diameter with a 10-cent coin (comparable with Russian coin 10 kopeks).
According to the company, in the case of the smartphone can accommodate two such antennas. Now the company is busy shrinking of the physical dimensions of the antenna, and next year promises to show a pattern reduced by 50%.
The timing of the start of mass sales of 5G-smartphone
The beginning of the supply modem chipsets Snapdragon X50 5G in small series for test orders is expected before the end of 2017, the commercial supply of Snapdragon X50 5G is scheduled for the first half of 2018.
According to representatives of Qualcomm, the world’s first commercial 5G batch of smartphones based on the Snapdragon chip X50 can appear at retail in the first half of 2019.
