Application of 4G communication

Answer 1

8.1 4G Car :

With the hype of 3G wireless in the rear view mirror, but the reality of truly mobile broadband data seemingly too far in the future to be visible yet on the information super highway, it may seem premature to offer a test drive 4G. But the good news is, 4G is finally coming to a showroom near you.

8.2 4G and public safety

There are sweeping changes taking place in transportation and intelligent highways, generally referred to as "Intelligent Transportation Systems" (ITS). ITS is comprised of a number of technologies, including information processing, communications, control, and electronics. Using these technologies with our transportation systems, and allowing first responders access to them, will help prevent ‐or certainly mitigate ‐ future disasters.

Communications, and the cooperation and collaboration it affords, is a key element of any effective disaster response. Historically, this has been done with bulky handheld radios that provide only voice to a team in a common sector. And this architecture is still cellular, with a singular point of failure, because all transmissions to a given cell must pass through that one cell. If the cell tower is destroyed in the disaster, traditional wireless service is eliminated.

8.3 Sensors in public vehicle :

Putting a chemical‐biological‐nuclear (CBN) warning sensor on every government‐owned vehicle instantly creates a mobile fleet that is the equivalent of an army of highly trained dogs. As these vehicles go about their daily duties of law enforcement, garbage collection, sewage and water maintenance, etc., municipalities get the added benefit of early detection of CBN agents. The sensors on the vehicles can talk to fixed devices mounted on light poles throughout the area, so positive detection can be reported in real time. And since 4G networks can include inherent geo‐location without GPS, first responders will know where the vehicle is when it detects a CBN agent.

8.4 Cameras in traffic light :

Some major cities have deployed cameras on traffic lights and send those images back to a central command center. This is generally done using fiber, which limits where the cameras can be hung, i.e., no fiber, no camera. 4G networks allow cities to deploy cameras and backhaul them wirelessly. And instead of having to backhaul every camera, cities can backhaul every third or fifth or tenth camera, using the other cameras as router/repeaters. These cameras can also serve as fixed infrastructure devices to support the mobile sensor application described above.

8.5 First responder route selection

Using fiber to backhaul cameras means that the intelligence collected flows one way: from the camera to the command center. Using a 4G network, those images can also be sent from the command center back out to the streets.

Ambulances and fire trucks facing congestion can query various cameras to choose an alternate route. Police, stuck in traffic on major thoroughfares, can look ahead and make a decision as to whether it would be faster to stay on the main roads or exit to the side roads.

8.6. Traffic control during disasters :

4G networks can allow officials to access traffic control boxes to change inland traffic lanes to green. Instead of having to send officers to every box on roads being overwhelmed by civilians who are evacuating, it can all be done remotely, and dynamically.
