The right posture for esports spectators: turn off your phone's Bluetooth and hotspot!

On June 1st, the second phase of the "Taste of Hangzhou" Dynamic Zone Cup National E-sports National Invitational Tournament started at Hangzhou E-sports Center. In the second phase of the competition, teams from Dream Three Kingdoms 2, Peace Elite Asian Games Edition and League of Legends will compete here.

I don't know if the friends watching the game heard this prompt before the start of the competition: "In order to maintain a good competition environment together, please turn off the wireless LAN hotspot and Bluetooth function of laptops, tablets, mobile phones and various wearable smart devices, thank you for your understanding and support!" ”

Radio technology is widely used in e-sports competitions, from competitions to broadcasts, sports displays to command and dispatch, from Internet access to wireless microphones... The orderly conduct of e-sports competitions is inseparable from the application of radio technology and a good electromagnetic environment.

So in order to maintain a good electromagnetic environment, what posture do audiences need to adopt to watch esports matches?

Watch the correct posture for esports matches, turn off your phone's Bluetooth and hotspot!

Unlike other competitions, e-sports competitions are held in relatively confined spaces, with high social attention, a large number of spectators, dense radio equipment, and a particularly complex electromagnetic environment.

If the on-site audience turns on the wireless LAN hotspot function and Bluetooth function of the smart device they are carrying, it may adversely affect the radio equipment during the competition, thereby affecting the quality of wireless transmission and transmission of various competition data. Therefore, friends watching e-sports competitions, remember to turn off Bluetooth and hotspots!

Not only the intelligent equipment of the on-site personnel, but also the walkie-talkie of the on-site staff, the wireless camera of the media, the communication system of the competition technical officer, and the wireless microphone of the commentary are all radio equipment. In order to minimize radio interference, the radio security team of the e-sports venue needs to do a lot of preparatory work in the early stage, mainly including: let the venue declare the required radio frequencies and equipment in each business area, explore the electromagnetic environment of the venue in advance, find risk points, give suggestions and formulate emergency plans.

According to Chen Rongmei, head of radio frequencies at Hangzhou E-sports Center, "Since the completion of the venue in April 2022, we have begun to explore the electromagnetic environment and understand the "background" of the venue's radio signals, and for the "Charm Hangzhou" Dynamic Zone Cup National E-sports National Invitational Tournament, we settled in the venue on May 4 to prepare for this event", "During the main competition of the Hangzhou Asian Games, we will face several times the operating pressure than this, and we will prepare in advance to ensure the smooth progress of the event".

It is understood that media in various countries are currently registering to apply for radio frequencies. On August 20, the frequency use application for the second phase of the Hangzhou Asian Games will be closed. At that time, the operation team of each venue can understand in detail what frequencies are used in the venue, how much radio equipment is used, and how radio equipment is used by various media, and the corresponding registration and coordination work will be done according to the actual situation.

The legendary quantum encrypted communication has also appeared this time!

In sports events, referees and technical officials need to communicate in real time, security and logistics teams must cooperate at any time, and esports players must communicate with each other, all of which need to be applied to the communication system of radio technology.

In this event, quantum encryption intercom technology tested the bull knife. Relying on the mobile 4G/5G communication network, on the basis of the security of the existing APN private network, the quantum cryptographic security capability is integrated to realize the identity authentication of intercom terminals, network and communication data encryption, and the security degree of communication data has achieved a qualitative leap.

The 5G intercom technology provided by Hangzhou Mobile is another black technology. With a walkie-talkie, you can make video calls in real time, which is also hot! At the work site, technicians can use the video function of the walkie-talkie to provide real-time guidance and solve problems, he said: "Compared with conventional walkie-talkies, the biggest feature is that it supports video backhaul function."

This is the first application of 5G intercom in large-scale events around the world, and real-time interaction with the dispatch management platform real-time can achieve accurate command, help the traditional digital walkie-talkie transform to intelligence, and ensure the smooth holding of large-scale events and activities.

Familiar cockpit, different IoT technology

As the data hub and running brain of the venue, the digital cockpit is equipped in many Asian Games venues, and I believe everyone is no stranger. In this event, the digital cockpit is still silently escorting the overall operation of the venue and the smooth progress of the event.

What is different is that in this event, the digital cockpit uses a new technology - 5G-A passive IoT technology when collecting information. This is specially deployed by Hangzhou Mobile for the stable operation of the computer room of this event. Walking into the Hangzhou E-sports Center, looking up at the ceiling, you will find many rectangular black facilities that are flashing, which is the world's first real-time environmental monitoring application based on 5G-A passive IoT technology. In Hangzhou Esports Center, there are many such transmission devices, which do not even need to be configured with a power supply, but use the received radio wave energy to transmit data.

During the operation of the event, the stability of the equipment in the computer room is crucial. The environment of the computer room requires stable temperature and humidity, and this data can be collected by these real-time environmental monitoring applications to achieve real-time monitoring of the computer room environment.

Combined with the "digital cockpit", the temperature and humidity of the computer room can be monitored in real time on the large screen, and once it exceeds the standard range, the "digital cockpit" immediately starts intelligent adjustment. It has four advantages of low cost, low power consumption, wide coverage and high accuracy, helping the Asian Games venues operate highly reliably.
