What You'll Learn
Smart meters use wireless radio technology to transmit data
Smart meters are Internet of Things (IoT) devices that measure and record electricity, gas, or water consumption in real time and relay the information to utility companies. They use wireless radio technology to transmit data.
Radio signals are susceptible to interference from other wireless devices, and in some cases, smart meters may require additional infrastructure, such as repeaters or gateways, to ensure reliable communication. To overcome this challenge, some smart meters rely on existing cellular networks (e.g., 4G or 5G) for data transmission, which offers better resistance to interference.
In certain scenarios, smart meters may also use hardwired connections, such as ethernet, to communicate with a gateway. This approach involves a significant upfront investment in deploying cables or wiring and requires a thorough understanding of the building's layout.
Smart meters play a crucial role in digitizing energy systems and offer benefits such as remote reading capabilities, quicker power restoration, increased access to energy usage information, and more pricing options. They also contribute to reducing pollution by eliminating the need for meter readers to travel to each residence.

Readings are sent automatically to energy suppliers
Smart meters are connected to a secure network, allowing energy suppliers to access data on energy usage. This removes the need for regular house visits or manual meter readings by consumers. Energy usage data is turned into a packet of data, which is then encrypted and transmitted to an in-home display that shows how much energy is being used or sold back to the grid.
The data is then sent from the home to a wide area network, which is made up of mobile phone or radio masts. From there, the data is transmitted to DCC servers. This process ensures that energy suppliers can receive data on energy usage without having to physically access the meter.
Smart meters use wireless radios to send usage information securely. This technology enables customers to better manage their energy consumption by tracking their usage at any time throughout the month. It also helps energy suppliers to locate power outages and restore power faster.
In addition to wireless radios, some smart meters may also have radio transmitters that communicate with the utility company. This allows the company to receive meter readings and locate power outages. These radio transmitters operate within maximum permissible exposure (MPE) limits set by the Federal Communications Commission (FCC).

Smart meters can be read similarly to a car's odometer
Smart meters are devices that measure the amount of electricity a customer uses. They are similar to traditional mechanical meters in that they only take whole-house readings of energy usage. However, smart meters can transmit this information automatically and remotely to energy suppliers, who use it to generate accurate billing. This is done through a radio signal, with the data being securely encrypted.
The similarity between smart meters and a car's odometer lies in the way they display information. Just as an odometer shows the distance travelled by a vehicle, a smart meter displays the amount of electricity used, measured in kilowatt-hours (kWh). Each kilowatt-hour represents 1,000 watts of electricity used for one hour. For example, using a one-kilowatt appliance for two hours would result in a consumption of two kWh, which would be reflected on the smart meter's display.
While the specific mechanisms may differ, both devices provide a clear and direct representation of their respective measurements. The odometer in a car indicates the distance covered, often in miles or kilometres, by utilising either mechanical cogs or a digital display. Similarly, a smart meter offers a straightforward reading of electricity usage, allowing users to track their energy habits and make informed decisions to save money.
In summary, smart meters and car odometers share a common purpose of providing valuable information to their users. While odometers track distance, smart meters monitor electricity usage, and both do so in a way that is easily understandable, much like reading the mileage on a car's odometer display.
