| 9 | 3 | laforge | You can find more information about Cell Broadcast in general at [[cellular-infrastructure:Cell_Broadcast]] and [[cellular-infrastructure:Service_Area_Broadcast]], as well as [[cellular-infrastructure:Emergency_Warning]] and [[cellular-infrastructure:Public_Warning_System]]. The pages include pointers to the relevant specifications. |
