The Evolution of Push-To-Talk Author: Mike Williams
My earliest memory of a ‘walkie-talkie’ is of a toy one I had as a child, and using it to communicate whilst out playing with my brother. It was great to just push the button and be able to talk.
With the availability of analogue and new digital radios, the situation is much the same. It still offered immediate connectivity through the ‘Push To Talk’ button. This immediate, fuss-free connectivity became essential for mission critical users such as Police, Fire or Ambulance who depend on them to help save lives.
Move into the early 2000s and cellphone users were asking to be able to connect ‘like radio users do’. This drove the development of new (infant) technology for providing a ‘PTT-like’ ability on 2G/2.5G cellphones but it was not reliable or robust enough for mission-critical applications.
Since then, cellular networks have rapidly advanced to 4G/LTE that supports bandwidth-intensive mobile data applications. PTT over broadband was developed to meet the needs of commercial users. PTT over mobile broadband has now been evolved to support mission-critical users too. Key to this evolution has been the development of international (3GPP) mission-critical standards:

Where does Motorola Solutions fit in? We continue to contribute to 3GPP standards related to mission-critical communications and lead the industry in standards implementation and compliance. Today’s mission-critical PTT users benefit from sub-second call set-up, high voice quality, numerous advanced features, as well as multimedia applications integrated on the same device.
What does this mean for Public Safety radio users? We recognise that when it comes to push-to-talk communications, one size, or in this case, one technology does not fit all. The right PTT communication platform should fit within your existing workflows, not the other way around. Our breadth of PTT solutions include PMR solutions (analogue and digital) such as ASTRO P25, TETRA and DMR standards as well as WAVE, our broadband PTT which operates over any broadband network.
The evolution of PTT has created a world of multiple technologies, and technologies that can interoperate. This enables each user to have the right technology for their situation. An example of the collaboration between technologies is Lowland Rescue:
Out in the field the rescue teams communicated by two-way radio and thanks to the interoperability provided by our WAVE solution, were able to keep a rescue-team member (at home) up-to-date with developments via a broadband connection.

Key Mission Critical Challenges for Connecting Africa Author: Tunde Williams
Mission Critical Technologies Africa 2018 in Cape Town, 13-15 November 2018
I am excited to be exhibiting and speaking at this year’s Mission Critical Technologies Africa.
We will be showing how we can use our technology to solve communications challenges faced by police, fire and rescue, ambulance and other public safety agencies throughout Africa.
What are those challenges?
Visit us on stand A84 and learn from our experts about our range of solutions that can help you address these challenges:
The new ST7500 compact TETRA radio, Ultra Portable LTE Infrastructure, our LEX L11 Mission-Critical LTE Device, Si500 Body Worn Camera, Avigilon Appearance Search™ and Unusual Motion Detection, Control Room Systems coupled with our Command Centre Software, Managed and Support Services to maximise your system’s availability and equipment uptime, high performance networks - MOTOTRBO™ Capacity Max and DIMETRA Express, WAVE broadband push-to-talk and a range of purpose-built TETRA, MOTOTRBO, ASTRO 25, and LTE devices. Wow!
Read our dedicated event guide to find out more.
I am also excited to be speaking in the conference on a very topical subject:
'National mission critical networks – leveraging digital technologies alongside broadband' in 'Connecting Africa' on Thursday 15 November 2018 from 12:50 to 13:10.
Visitor passes for Mission Critical Technologies Africa are free. You can register here.
Mission Critical Technologies Africa is also co-located with AfricaCom so you could easily combine visits to both. Visitor passes for both events are free.
You can also keep up-to-date with news and events on our Safer Cities, Secure Businesses Africa microsite at www.motorolasolutions.com/saferafrica
I look forward to seeing you in Cape Town.

Increasing Connectivity Exposes New Cyber Attack Vectors Author: Troy Mattern
Can your cell phone be used to steal your email password or fingerprint data? Can hackers access personal information from your heart rate monitor, fitness tracker or smartwatch? What may have once sounded like science fiction is rapidly becoming reality.
We now live in an era of connectivity – with digitally connected devices permeating every aspect of our lives. In fact, as soon as 2020, the number of connected devices will reach more than 21 billion. This level of interconnectedness is enabling people and businesses to do things never before imagined – from home automation to environmental monitoring.
Today’s increasingly connected world is also introducing more attack vectors and more possibilities for cyber crime. Unfortunately, some of the most commonly used interconnected devices contain vulnerabilities. At a recent DEF CON, 47 vulnerabilities affecting 23 connected items – including webcams, door locks, thermostats and baby monitors – were disclosed. With these vulnerabilities, cyber criminals now have more entry points and can move laterally across networks. As a result, cyber attacks can have far more extensive effects than ever before. Despite this information, 80 percent of organisations do not routinely test their IoT apps for security vulnerabilities.
Developing resilience to withstand cyber attacks is critical to future success. Safeguarding software and connected devices – and making it as difficult as possible for exploitation – will help to improve overall organisation system security.
Organisations must be proactive and operate in a state of readiness. Embracing a holistic, risk-based strategy enables organisations to manage their risk awareness, security, detection, response and recovery. By focusing on mitigation options, continuous monitoring, diagnosis and remediation, companies are better able to protect themselves and proactively confront potential situations before they become an acute threat.
Read the full Motorola Solutions White Paper here to learn more about the emergence of new attack vectors and how a holistic strategy can help defend against emerging cyber threats.
