CBS ระบบเตือนภัยที่ทั่วโลกมีแล้ว แต่ไทยยังไม่มี เตือนภัยแผ่นดินไหวถึงล่าช้า
Summary
Thailand still lacks Cell Broadcast Services, the alert system many countries already use.
The difference from the SMS Thailand uses is that cell broadcast reaches every handset in an area at once, without needing numbers and without network congestion.
More than thirty countries have it, which makes Thailand’s delay a decision rather than a technical problem.
Key points
SMS was not designed for emergency alerts
Sending one number at a time congests the network exactly when speed matters most.
Cell broadcast does not need to know who is there
The signal goes to the whole cell, which covers tourists and people who just arrived.
Thirty countries is proof it can be done
With that many examples, the technical difficulty argument does not hold.
The delay has a cost measured in lives
In an earthquake, a difference of minutes is the difference between leaving a building and not.
