On April 26, Wang Peng, member of the party group and deputy director of the Jiangsu Provincial Communications Administration, and heads of relevant departments walked into the all-media live broadcast program of "Political Style Hotline • I Will Help You Ask the Director". Mr. Wu, a Tesla owner from Nanjing, reflected in the program that whenever he parked a new car in the underground garage of the community, the car had no signal at all, and all the functions that relied on the mobile network could not be used. Can this problem be solved at this time?
Tesla's "Internet of Vehicles" cannot be used as soon as it enters the basement
China Unicom is a communications partner
According to the program report, although Mr. Wu's vehicle shows a Unicom 3G signal connection in the basement, whether it is remote vehicle control, audio and video applications or in-car game functions that require networking, all of them cannot be used.
"The control that needs to be connected to the internet cannot be controlled on the mobile phone, and various functions are not ok." Mr. Wu said.
However, the vehicle drove out of the basement and all functions returned to normal.
Tesla responds:
Car machines cannot receive the signal band of the underground garage
Not an isolated case
Tesla after-sales personnel said that the reason why the car has no signal in the underground garage is because the car machine cannot receive the signal band of the unicom company in the underground garage, and many car owners have reflected on this.
Unicom Engineer:
Signal of underground garage deployment
Tesla just couldn't take it
Subsequently, Mr. Wu called China Unicom Complaint Center. On the afternoon of April 21, engineers from China Unicom Nanjing Company inspected the scene and said that the base station deployed by China Unicom in this underground garage transmitted 4G signals in the 850 megahertz and Band 5 bands, and no other frequency band signals were deployed. And this signal Tesla car machine just can not receive, so there is no signal.
"It may be that when Tesla Motors is producing the on-board host, it does not have this signal band, and it cannot receive it in the Band 5 band." Engineers at China Unicom Nanjing said.
The engineer also said that to solve this problem, on the one hand, the owner can wait for the follow-up upgrade of the car manufacturer, on the other hand, the staff of Unicom will also reflect this situation to the superior leader. However, it is difficult to solve the problem in a short period of time.
China Unicom Jiangsu Company:
Push Tesla to achieve software upgrades as soon as possible
Negotiate with the on-site property to find a solution
Ma Rong, deputy general manager of China Unicom Jiangsu Company, responded in the program that Tesla car machine does not support the problem of the underground garage network signal band, and Unicom has reflected to Tesla car companies, and Tesla will deal with it as soon as possible through software upgrades.
On the other hand, China Unicom will also contact the property according to the actual situation of the user's underground garage to see if it is possible to solve it through other means.
