Last week, b-mobile subscribers in Bhutan received a message that cell broadcasting had been enabled on the system. It was the same week LIRNEasia recommended that cell broadcasting was the best option for effecting public warning in the mountainous country that is vulnerable to massive flash floods known as Glacial Lake Outburst Floods
CB [cell broadcasting] is an intrinsic feature of GSM, UMTS and IS 95 CDMA networks, and is thus available in the two Maldivian networks. But it must be activated. Most handsets are capable of receiving CB messages but the feature must be turned on. However, in the early stages, getting customers to turn on the feature could be an effective way of educating them of mobile-based public warning. Following stakeholder meetings that included sharing of information on the ongoing CB channel-standardization work of Study Group 2 of the Telecommunication Bureau of the International Telecommunication Union (ITU-T) and experience in attempting to use CB for public warning in Sri Lanka, the recommendations to TAM are being finalized.
