How will Apple and Google track the spread of the Corona virus over a Bluetooth connection?

Google and Apple have announced a controversial project collaboration aimed at developing a contact tracking system for smartphone users that will allow users to understand who is in contact with infected patients and prevent the Coronavirus (COVID 19) Diffusion.

Although there are still few details about the system (so far), the two companies have not released all the information about the system, but the new tracking system will surely use the technology currently being used. On most smartphones (Bluetooth LE).

Below you will learn how to use a Bluetooth connection to track the spread of Apple and Google Corona viruses.

What is Bluetooth LE?

It is an alternative low energy communication technology to standard Bluetooth technology that focuses on transmitting shorter waves than traditional Bluetooth connections, features low energy consumption and has the ability to connect to multiple devices at the same time.

Apple AirPods principle is the first example of using this technology. A short-range Bluetooth LE connection is used to connect to traditional Bluetooth. To stream the music you want to listen, you must first connect and pair the wireless headphones.

Therefore, we found it important to choose Bluetooth LE technology in the new contact tracking system for several reasons:
  •     Supports many smartphones: Supported by almost all modern smartphones, from the cheapest Android phone to the most expensive iPhone or Samsung.
  •     Low Energy Consumption: It has the ability to operate at very low power levels without affecting battery life.
Although Bluetooth LE technology can help people find missing things, it is not suitable for accurate physical positioning, as interference can negatively affect positioning accuracy.

The more obstacles between devices (such as backpacks, walls, or windows), the less Bluetooth LE can determine the precise location, as these obstacles weaken the strength of the previous wireless signal. Measure the distance.

As a result, we found that Apple uses a completely different technology, which is the ultra-wideband technology in the iPhone 11.

However, the problem is that only a few phones still support UWB. We have found that every phone has Bluetooth technology. This makes it the only real option for local communication from one device to another, as it is not necessary for external networks like Wi-Fi, GPS, or cellular data.

However, if you warn of being exposed to the corona virus, some limitations to the Bluetooth LE's limited bandwidth technology can really help as it works better in the open air.

Bluetooth connectivity also provides a better solution than QR codes. QR codes have been used in South Korea and other countries and there is a need to apply social differences. This is a major factor in preventing the spread of the coronavirus. We have found that using Bluetooth connectivity is the best solution to follow users and warn them against approaching them. From the patient or his phone.
