Electronic enthusiasts eight o'clock: Recently, Datang launched the 5G field rate and coverage capability test, macro base station and dense coverage small base station in the 3.5GHz band based on the Beijing Huairou field test environment in the second phase of China 5G technology R&D test. The switch between the two, and the coverage of the future convergence network, marks the 5G test into the system verification phase.
In the actual measurement, Datang conducted the industry's first 5G base station coverage capability test, using large-scale antenna technology to maintain a coverage distance of more than 2km at a download rate of 100Mbps in the 3.5GHz band, achieving a coverage capability similar to that of a 4G base station in the 2.6GHz band.
China's 5G technology R&D test was launched in January 2016 and was divided into three phases: key technology verification, technical solution verification and system solution verification. The first phase was completed in September last year. From September 2016 to September this year is the second phase of the 5G R&D technical test system verification test.
It is understood that the second phase of testing will be based on unified equipment specifications and test specifications, testing for 5G typical scenarios. At present, Huairou in Beijing has launched the world's largest 5G test field construction, which can meet the needs of field single station and networking performance testing, as well as interoperability testing between equipment manufacturers and instrument and chip manufacturers.
The 5G Phase II test focuses more on the technical solutions for different application scenarios of 5G mobile Internet and IoT, including continuous wide coverage scenarios, low latency and high reliability scenarios, low power consumption large connection scenarios, and hotspot high capacity (low frequency). Performance testing of scenarios, hotspots, high-capacity (high-frequency) scenarios, high-and-low-frequency hybrid scenarios, and other mixed scenarios, and multi-party interworking tests.
It is understood that Datang's Huairou first station completed construction at the end of February this year, including a macro station supporting large-scale antennas, as well as two light pole stations, and will further increase the number of small stations to form a dense networking environment. At the same time, Datang has also built a complete experimental environment. The core network and local business are based on the advanced virtualized cloud platform, and will support the new network architecture in the future.
At present, Datang has completed test scenarios such as outdoor fixed-point rate, mobile remote and 4G/5G coverage comparison, and macro-micro base station switching, providing verification and support for 5G system design and standard advancement. In the test, the core network adopts a unified virtualized cloud platform, which can meet the diverse scenarios of 5G, support the core network function and the deployment of localized services; its high real-time operating system has an average delay of only 2-5 microseconds.
In addition, the first macro-dimensional coverage scene built by Datang realized the macro-micro collaborative networking and dual connectivity, and it has a typical verification environment for 5G stereo networking. As a 5G technology test base, Huairou trial network environment will continue to be built, and follow-up Datang will gradually carry out testing of more scenarios such as low latency, high reliability, low power consumption and large connections, and will form 5 to 7 stations at the end of the year. The scale network environment supports subsequent network performance verification.
While advancing the 5G technology test, Datang launched the Datang 5G Industry Partner Program, and cooperated with the Chinese Academy of Sciences, Qualcomm, Intel, Keysight, China Automotive Engineering Research Institute and other industrial chain multi-link partners to actively build terminals and chips. 5G industry ecosystem such as network, business application and test instrumentation, build 5G industry international alliance, and promote the rapid maturity and rapid deployment of 5G industry.
According to the timetable published by 3GPP, the first version of the 5G standard (3GPP Release 15) will be completed in September 2018. The standardization and industrialization of 5G has entered the sprint phase.

Why choice TONYA water vapour fireplace ?
A real alternative to conventional inserts and traditional fireplaces, 3D cold-flame steam fireplaces have unmatched advantages. In particular, they make it possible to overcome the main constraints of installation, operation and maintenance encountered in fireplaces that use wood or gas.
It is a subtle fusion of three components, namely, ultra-fine water vapor, the light emitted by the RGB LED, and the action of the fan and the heating wire, making it possible to obtain a simulated hand-touchable colored flame.
Ultrasonic waves are produced by "transducers" (or sprayers), which are mechanical waves that will vibrate (silence) water and convert it into ultra-fine water vapor. Under the action of the fan, the heating wire generates a temperature that can be touched by the hand. After heating, the water vapor is radiated into the surrounding air and illuminated by LEDs.
Ultra-fine water vapor (only a few microns) is immediately absorbed by the surrounding air. Water vapor will not condense and will not generate moisture on adjacent walls. This is commonly referred to as dry water vapor.
