Bigbelly continues to be humbled as an icon of Smart City and IoT movements with our solution and story starting far before ‘smart city’ was a coined term! We’re honored to keep up the momentum as thought leaders in the telecom hosting space by delivering a multi-function city infrastructure for hosting additional technologies. Read on for an industry article highlighting the realities of 5G technology deployment in Smart Cities where Bigbelly’s SVP of Information Communications Technology, Alex Gamota, is cited:
Smart city: enthusiasm but caution on new 5G technology
5G networks no doubt have the technological specs necessary to power smart cities, but without careful design and planning the complexity of integrating everything from traffic to health care could prove overwhelming
Long-touted advances of smart cities may finally become reality with the increases to wireless network speeds and bandwidths promised by the switch to 5G. Seamless integration of our homes, cities and utilities can change the way we interact with everything from grocery stores to doctors.
The 5G upgrade will make some smart city applications, which until now were only possible in principle, a reality. Applications like autonomous public transport, smart energy and utility grids and remote/in-home connectivity to medical services and assistance for example.
While it has been easy to envision these applications, previous networks were inadequate and couldn’t carry the amount of data needed, reliably or quickly enough. Massive increases in the speed and capacity of 5G networks, coupled with practices like network slicing (where multiple virtual networks each customised for specific tasks can be created and supported by a common physical infrastructure), could create the network environment to support a true smart city. With the speed and data capacity issues potentially solved, it will be important to ensure the connectivity of the upgraded networks.
“Aside from speed, the connectivity of the networks is a very important aspect,” says Dr. Knud Skouby, from the Center for Communication, Media and Information Technologies at Aalborg University in Copenhagen. Unbeknownst to most, our devices are constantly jumping between networks as we move through a city, for example connecting to Wi-Fi upon entering a building. This creates a risk for connection problems. A lost connection on a phone call is annoying but, “when it’s a fully autonomous car in a complicated traffic situation it is not only annoying, it could be a catastrophe,” remarks Skouby. 5G offers better connectivity that can mitigate and perhaps eliminate these risks.
However, as Dr.Skouby points out, there are still some unexpected challenges associated with upgrading to a truly smart city. “5G is the engine that can make this possible but to make it useful we have to think about how it will be built.”
Planning how and which systems will connect or talk to each other is a massive undertaking involving engineers, data scientist programmers and governments. If the many separate systems and software are not designed properly, the promises of efficiency and speed cannot be kept. Considerations concerning the integration of hardware like sensors, antennas and fibre optics cable are another planning challenge.
Facilitating smart city and 5G infrastructure could create a huge demand for public real-estate. Alex Gamota, Sr. VP and General Manager for the ICT Division of Bigbelly, a provider of smart waste bins and other smart city platforms, cautions that this space needs to be carefully allocated.
“Think of a streetscape where you have a traffic sign, often times that pole will have several signs on it. If you had stand-alone structures for each application, there won’t be enough real-estate,” he explains.
Cooperation between the caretakers of public spaces and utilities and private companies will be a necessity. “Real-estate and public space is a scarce commodity,” says Gamota. Therefore a clever use of existing infrastructure is needed to “help us maintain our streetscape.”
Ensuring all citizens can take advantage of these advances will also require cooperation between public and private sectors, as there is a real chance that rural residents, for example, might be left behind. “To that end, as 5G-enabled services emerge, it is important the public sector have a place at the table and make the improved services that 5G enables available to all citizens,” says Raphael Gindrat, CEO & Cofounder of BestMile, which provides platforms that manage fleets of autonomous vehicles. Furthermore, all of these applications require new sensors, collecting and sending data so privacy and security risks increase too. “They will need to be secured and people need to be aware of what they share through their connected devices.”
According to Dr. Skouby, the public and private sectors must work together on improving the management and protection of data. “We have to find a better way to let people know what is happening and consent to it.” Without public trust these systems will fail. “We are seeing the tip of the iceberg today with Facebook and Google, but in the future it will be on a completely higher order of magnitude.”
