Picture yourself on a date in a club full of really loud people and you’re trying to talk with someone next to you. Unfortunately, they just can’t hear you because everything else is too loud. Many networking systems suffer from similar issues. Only so many transmissions can be sent at one time, in one area until there is so much “noise” that the transmission collides with another and can’t get through. This is referred to as “data collision”.
Some Smart City technologies are used to manage emergency services. For example, a wireless device designed to contact the fire department when a fire is detected. If this device isn't able to send a timely signal, the fire could spread.
Hence why we view not all data as being "equal", some data has a higher resource allocation need and this is why MXC is ensuring the right data gets delivered in a timely manner.
LPWAN is a long distance wireless network similar to 4G. The difference? This network is designed specifically for transmitting sensor data and anybody can set up their own network. Moving smart city devices to a dedicated network reduces the potential of data collision.
