• There won’t be a one-size-fits-all mobile interface client,
because specific interfaces will be mapped to people’s
roles. You’ll have one interface for a security guard,
another for a policeman, and another for an undercover
• A radio can operate in direct mode, where one radio user
can talk to another without any base station or network.
Today that feature does not exist in mobile phones
because they need to talk to a tower. But this upcoming
standard will let you communicate mobile phone-to-mobile phone, if you’re within range — a really important
feature for firefighters on a fire ground.
• Priority calling will give specific frontline workers higher
priority on public networks than regular public network
Those features will be ratified by 3GPP in 2016 and will be
in place in cellular network equipment as a software module
within a couple of years, although realistically, it will be
longer before they have an impact.
And the new standards still won’t solve some other inherent
disadvantages of public cellular networks, such as the
lack of backup generation for 4G towers and the radio
base stations. So if the power goes down, so does the
cellular communication. Typical LMR towers, however, have
anywhere from two to five days of backup power generation
at each site.
So even though it is not yet mission critical, there are plenty
of good reasons to invest in PTToC. By unifying critical
communication networks you can give your users choice
and advanced coverage while they work with the reality of
multiple networks. PTToC brings added redundancy and a
simpler interface that will improve their safety, efficiency,
and user satisfaction.
