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.

"So this is built into the engine that we put on the top of the LTE. So you take a normal LTE which also has a prioritisation. A normal LTE also has a prioritisation. So for example SingTel has an LTE, the CEO of SingTel would have the highest priority. If he is sending a video it will perhaps over-ride. The Prime Minister of Singapore would have priority or maybe they have a list of people who have priority but that is fixed. It is pre-determined."

Privacy violations

"Recently we have seen a lot of criticism in terms of privacy violations and all that. How will that be managed in this?" I ask him.

"The first thing is when their public safety is dealing with this, they will be dealing with very sensitive data," says Bhatia. "For example, very sensitive videos will be moving out if they have captured some suspect or they have seen a bomb. Those are really very secure data. If you put it on a normal LTE, it will quite likely get leaked or hacked or something like this.

"So one of the major features that is needed to convert a normal LTE into a public safety LTE is to build in those additional layers of security, additional layers of safety that this data doesn't go out. So privacy is one of the most important features and the one that I mentioned - dynamic prioritisation. The second and more important is this privacy. This data actually needs to be more secure than a normal LTE. A normal LTE is also secure, it's not that anyone can hack into it but people do but in this one, they cannot.

"So it is a very specialised key and very dynamic, what they call the 'secured key'. The key is managed by the agency themselves. Even we do not get access to that key. So this is what I have at the moment."
