"The ability to deliver accurate and timely warnings and alerts through cell phones and other mobile devices is an important next step in our efforts to help ensure that the American public has the information they need to take action to protect themselves and their families prior to, and during, disasters and other emergencies," said FCC Chairman Kevin Martin in a statement.

The news means that the FCC has adopted the technical requirements for the wireless emergency notification system so that US carriers that choose to participate can begin making the necessary tweaks to their networks and services. Right now, carrier participation is voluntary, and it's unclear which major wireless providers will work with the FCC

The system will initially distribute simple text alerts, but could include audio and video notifications in the future, the FCC says. Vibration notifications and "audio attention signals" will also be sent so that disable persons receive alerts, as well. The CMAS could become available in 2010, according to The New York Times.

Text-message-based alerts and cell-phone-based emergency notification in general aren't new, of course. Many organization and academic institutions have been using various forms of mobile alerts for some time. (There's even a notification system meant specifically for iPhone users.) And with text messaging quickly becoming one of the most common forms of digital communication-more than 48 billion text messages were sent in the month of December 2007 alone, according to CTIA, a wireless industry group-it makes perfect sense to institute a US nationwide text message alert system.

One has to wonder what's taking the FCC so long. And it's also worth noting that even though the groundwork is now in place, "no federal agency has stepped up to fulfill the unified aggregator/gateway role that virtually all stakeholders agree is necessary for our mobile alert system to work properly," according to Michael J. Copps, FCC Commissioner. Copps says the Federal Emergency Management Agency was expected to fill that role, but it pulled out less than two months ago, citing statutory requirements and other reasons that would bar it from taking on the responsibility. Now it looks like another agency, possibly the FCC itself, will have to step up to the plate.

I don't mean to belittle the FCC's announcement because the initiative is admittedly a grand one-in both scale and purpose-but two more years sounds like an awful long time to wait before such a system is up and running. Though I guess having a cell phone notification system a couple years down the road is better than not getting one at all...and it's likely going to take longer than that if the FCC can't find an agency to oversee the process and cellular carrier participation remains voluntary.
