There are complexities in interconnecting agencies but more at the social layers than at the technology layers. The Simon Fraser University (SFU) Mobile Communications (MobComm) Truck was designed to patch a Regional Emergency Operations Centre (REOC), specifically the British Columbia Provincial REOC (termed as the PREOC) communicating through the Internet (TCP/IP) and public telephone lines (PSTN). The first-responder (e.g. forest firefighters) naturally communicate with Ultra High Frequency (UHF) radio sets.
The title of the article “Sri Lanka to de-regulate payphone business,” is a little deceptive, but then that is probably not the fault of the Director General, but of the editor of LBO. LANKA BUSINESS ONLINE – LBO Sri Lanka plans to allow third parties to operate payphone booths in an attempt to popularise them in far flung areas outside the city of Colombo, a top official said.The island’s eight public switched telephone network (PSTN) operators will now be allowed to appoint a third party to operate and maintain a public phone booth on a revenue sharing model. “Its a scheme similar to selling lottery tickets, where the lottery operator does not undertake the burden of running, maintaining and collecting the money,” the head of Sri Lanka’s telecom watchdog, Kanchana Ratwatte said.
