How spectrum can save lives

Zafar Anjum | July 15, 2013
Motorola Solutions’s Bharat Bhatia, Regional Director, Government Affairs for the APAC and Middle East regions, speaks on public protection, spectrum harmonisation and why Asia is leading in this area.

"There is another third technology which is a lower cost technology called the DMR which again, is a digital radio but for the lower end maybe for industries, for couriers or for the commercial users. So you have those three technologies - TETRA, P25 and DMR. They are all narrow band technologies, they only cover wireless and are slow speed data like GSM. When you come to the high speed data, video or broadband, the technology search has been going on for the last 10 years, what should be the best technology for public safety.

"End of the day, everybody felt that when you are investing in that kind of technology, it is best to follow the standard technology, the global standard technologies. So worldwide there is an agreement that the best technology for this is LTE because LTE is used by the commercial operators also. The same technology can be recognised and made secure to meet these requirements so you take in a standard LTE technology, put the additional features in hardware to make it recognised, safe and secure and then call that as a public safety LTE. So what Motorola does is it takes a normal LTE from Ericsson or whoever makes that LTE and puts on it our public safety engine on top of it to make it safe and secure and responding to it. So it has all the applications that are needed for driving this. From a technology perspective, we are going all in all with LTE, not only we but everybody else. So anybody who is in this area, LTE is considered the technology for this."

"So using LTE as a basic technology, we put our public safety engine on top of that which basically converts a normal commercial LTE into a public safety LTE and has a feature like safety, security, recognition and using the handset like I showed you. Also it has one very important feature that is needed in public safety is what we call 'dynamic prioritisation'.

"What happens is suppose there is an incident somewhere; let's say that there is a bombing that has taken place here. The commander at the site, he's the most important person as he is the one who is going to drive everything there. He should be able to command whatever resources he needs to manage that scenario. A typical problem in any cellular network is the bandwidth and capacity that is available. So that capacity should be prioritised that I need most of that capacity for the videos that are going from the scene to the experts in Japan or whatever.

"So he decided on the go at the dynamic level that at my capacity, say that I have 60 Mbps available, 10 Mbps is dedicated to this. So this thing will get highest priority. Of this top group which is managing fire in this area will be getting the highest priority. And these things keep on changing. Maybe there are two incidents going on at the same time and different priorities are needed but it is these people who actually determine the priorities.
