Halo will launch a remotely operated car service powered by 5G in Las Vegas 5G technology has generated a lot of hype for its potential to power driverless cars using a remote operator, but for the past few years that’s all it’s been — hype. Las Vegas-based startup Halo and telecom giant T-Mobile are teaming up to change that, with a driverless electric car service in Las Vegas powered on 5G to launch later this year. The service, which will start with five vehicles, will work by connecting users to Halo’s pilot fleet of vehicles via an app. After a user has ordered a vehicle, a remote operator will drive it to the waiting customer. Once the car is delivered, the user can get behind the steering wheel and operate the vehicle as normal for the duration of their trip. When the trip is complete, the remote operator takes back over and drives it to the next waiting customer.
