China Telecom ‘Healthy WiFi’ Case Study

By offering ‘Healthy WiFi’, China Telecom wanted to help its customers avoid cervical spondylosis, potentially caused by poor posture associated with cell phone use. So, China Telecom offered ‘Healthy WiFi’, which connects only when the phone is at a 70 to 75 degree angle. Otherwise, WiFi disconnects automatically.


Bad posture causes neck, shoulder, and back pain when using smart phones to surf the internet. The symptom is known as Cervical Spondylosis.

There are at least 56 million people diagnosed with Cervical Spondylosis in China. Increasing by 1 million each year, there is a trend of sufferers getting younger.

According to findings of a CCTV experiment on smart phone usage, the harm of bending your neck at 45 degrees or lower is like having two watermelons hanging by your neck. The healthiest posture for your neck when using a smart phone is when the phone is at 70 to 75 degrees perpendicular to the ground, which means with your head upright, your eyes should only be tilting at 15 to 20 degrees.

How do we get people to develop a healthy habit of using smart phones? As people are constantly searching for WiFi, this is where we should start. WiFi will only be connected when the phone is at 70 to 75 degrees. Otherwise, WiFi will disconnect automatically.

  • Step 1:  Search and select Healthy WiFi.
  • Step 2:  On the Healthy WiFi page, tilt phone at 70 to 75 degrees perpendicular to the ground.
  • Step 3:  Angle validated, Healthy WiFi connected.

This is our solution: Healthy WiFi.

Healthy WiFi was made available at various locations throughout 13 cities in China. Most users are happy using their phones via Healthy WiFi.  The result: Within a month was 24.9% of users continuing to use Healthy WiFi to help them correct their bad posture.”
