What Is Machine To Machine Communication?


What is M2M?

Machine-to-machine communication is the ability of different devices to talk to each other and exchange information.

For example, you may have a sensor device such as a thermostat that needs to trigger an action when a certain level is reached. The information from the sensor is sent to another device, where it can be used to throw a switch or take an action to alert an operator to a problem.

Basically, it connects things to the web, allowing them to become part of an intelligent network. It allows key details to be sent without the need for human intervention, thus streamlining the way processes work, improving efficiency and cutting costs. That’s a simplified view but in the age of widespread computers and networks things are a bit more complicated.

Machine-to-machine (M2M) communication can now involve sending data over the internet to devices that are thousands of miles apart. This also means it’s expanded beyond one-to-one connections and information can be sent to many different devices in one go, or indeed a single hub can collect sensor data from many different sources.

The History of M2M

Interconnection of devices has been around for a long time and in fact pre-dates many of today’s computing technologies. Land-line communication is still common, whether by dial-up, broadband internet or ISDN links. Cellular communication is also popular and Siemens pioneered this is in the mid 1990s, developing a dedicated GSM data module known as M1.

M1 was used in early point-of-sale (POS) applications and in devices to allow the tracking and monitoring of vehicles. Early adopters were large multi-national companies such as General Motors, who were quick to see the potential offered by the technology. The latest mobile M2M units offer technologies such as built-in GPS that allow them to accurately report their position.

M2M can also be embedded into smart cards such as mobile phone SIMs, allowing it to be included in much smaller devices that can be used for applications such as tracking cargoes. We are now seeing a big expansion in the number of machines that are becoming M2M enabled.

In 2008 it was estimated that worldwide the number of mobile phone links used for M2M was some 47.7 million. By 2014 this is forecast to grow to 187 million, so the technology has taken off in a big way. The German market is particularly fast growing, with the 2.3 million M2M smart cards in circulation in 2010 set to more than double by the end of 2013.

Uses of M2M Today

Interconnected devices can be used to help performance and efficiency in a number of different ways. These include the production phase to ensure that components are delivered on time but also in finished products. For example, M2M can alert a manufacturer when a machine needs a service and can even highlight the faults that need to be rectified.

Another use of M2M is in the new generation of smart meters used by energy companies. These allow meters to send in their own readings at regular intervals and can alert the supplier to tampering or unusual activity.

The technology can be used in other ways to allow, for example, a central computer to update digital signage to display changing messages at different times of day or to update prices displayed at filling stations. Motor manufacturers have been quick to adopt M2M technology and it is particularly useful for electric cars where there is a high level of embedded technology already in the vehicle.

Ford, for example, has formed a partnership with AT&T to fit electric Focus models with a dedicated app and wireless connection.

This allows owners to monitor and control the car’s charge state and to plan journeys around the need to access charging stations. It can also be used to remotely trigger heating or cooling of the car prior to setting off on a journey.

M2M is also useful for fleet management, tracking drivers’ habits and journeys to optimise route planning and reduce journey times. It can be used to monitor driver behaviour and this is very useful not just for fleets but also for the insurance industry.

Motor insurance policies that use a ‘black box’ to check on driver behaviour are becoming increasingly common, especially for younger motorists. The technology can help the driver too, providing real-time traffic and weather reports tailored to the location of the vehicle.

The healthcare sector is another area where M2M technology is starting to make a difference. In patient care it can save lives, improve quality of life and cut costs. For example, remote monitoring can provide information on a patient’s condition whilst reducing the amount of time spent on hospital stays and visits.

It can help with assisted living for the elderly as well, allowing them to stay in their home for longer and enjoy a much better quality of life.

The Biggest Electrical Risks You May Not Be Aware Of

Everyone knows that electricity is flowing through the walls of most buildings. Most people don’t even think of the dangers that can come from having live electrical currents so close to people. Here are some little known electrical risks that can really hurt you.

Old Wiring

The National Fire Protection Association lists old wiring as a major cause of house fires and electrical injury. Approximately 50 percent of American homes were built before 1973, and many of these homes have never had an inspection by an electrician. The simple fact that a house is old doesn’t automatically mean that it has a faulty electrical system, but older homes do have a greater likelihood of having deteriorating or unsafe wiring.

Aluminum Wiring

Aluminum wiring was used in many houses built or remodeled in the 1960s and 1970s. The connection points are the hazard, not the aluminum wiring itself. The connection points can break down over time in a way that leads to overheating and potential fires.


A flood can be dangerous by itself, but the presence of live electrical current can make a bad situation worse. Even a small amount of water in the basement or ground floor of a building can cause an electrical hazard. Entering a flooded room that is still receiving electrical current is very dangerous. If flooding is expected, the electrical system of the building should be completely disconnected. If the flooding is unexpected, and covers any electrical cords or the electrical outlets themselves, the building should be evacuated until the power can be turned off.

No Grounding Protection

That third prong on an electrical outlet has an important function; to provide electrical grounding. Cutting that prong off to make a three prong plug fit into a two-hole outlet is a very bad idea. Electricity seeks the path of least resistance. Proper grounding allows any electric current that might come from a broken connection or loose wire to travel into the ground instead of into a nearby person.

Static Electricity

A static spark is not a huge electrical event, but static electricity is, as its name suggests, electricity. Although it is rare, a static spark can ignite gasoline vapors, according to the National Association of Certified Home Inspectors. Static sparks can also be hazardous in industries that use or store flammable chemicals.

Improper extension cord use

Extension cords are a great invention, bringing electricity wherever it is needed. However, improper extension cord use can lead to electrocution. According to Electrical Safety Foundation International, extension cords are not meant to be linked together for a quarter of a mile, nor are they intended to power an entire house. Improper use of extension cords can cause the insulation to break down, increasing the risk of electrical shock and fire.

Not Using Ground Fault Circuit Interrupter Outlets

Ground fault circuit interrupters (GFCIs) protect against electrocution by shutting off an outlet if a change in current is detected. GFCIs should be used if there is any potential contact with water, such kitchen, bathroom and outdoor outlets.

Do It Yourself Repairs

It may seem simple to change a light fixture or replace a faulty outlet. However, electrical repairs are not like other do-it-yourself projects. You can be injured or even killed if you touch the wrong wire, and incorrectly performed repairs can lead to additional problems, including fires. It is always a good idea to contact an experienced electrician for electrical repairs.
