“M2M can include the case of industrial instrumentation - comprising a device (such as a sensor or meter) to capture an event (such as temperature, inventory level, etc.) that is relayed through a network (wireless, wired or hybrid) to an application (software program) that translates the captured event into meaningful information (for example, items need to be restocked). Such communication was originally accomplished by having a remote network of machines relay information back to a central hub for analysis, which would then be rerouted into a system like a personal computer”.

M2M is a growing aspect of technology, devices communicating with devices. The DATASHED gateway is being used as a confidential conduit for SMS communications between devices in the field and computer based management applications.
For example: A District Council has a sensor monitoring water levels at a reservoir, if it falls below a certain level that data is sent via the network to a PC at the Council, it is transmitted as a value which is then converted to a measurable number and often integrated with a system like QTech’s DATRANvue to be viewed on screen in a meaningful and live format. A low level alarm can also be sent via text message to the required staff informing them so they can carry out the required action.
Like email, SMS is the type of communications that is prone to SPAM. Legislation is place to protect consumers and there is potential for unscrupulous spammers s to be prosecuted if caught sending SMS’s that are deemed to be SPAM. The Telecommunications Carriers Forum was formed as body to provide some self-regulatory regimes for Premium Messaging Services. All of the Telco’s have taken an involvement along with industry to achieve a common code of practice in the use of SMS.
The short codes in use by GroupSend have been taken into service with each of the Telco’s and measures are in place to prevent miss-use of the SMS service being provided. Note miss-use or notification of complaints from the Telco’s will result in the service being disconnected.
Many clients are using the DATASHED Gateway with an Integrated Solution to remotely monitor and interact with SCADA (Supervisory Control and Data Acquisition) systems and devices. These systems are sending out messages to staff or contractors who need to receive reporting information in order to ensure a system is running correctly or to be notified of an event that has occurred. By using ‘push’ services, events, alarms and information about a process are sent to the SMS Gateway by the monitoring application and then sending a pre-set text onto nominated mobile numbers.
Example: A Council might receive information that levels have dropped to below an acceptable level in a town water reservoir and that action needs to be taken. The system will receive a signal from the device at the reservoir which will trigger an automated SMS to be sent via the Gateway to a pre-determined contact list in the system. This could simply be a notification of the level or it could give the option to turn on a pump or activate a remote device to do a specific task.
‘Pull’ services now provide real power to the engineer or operator in the field. From their handset, they can use the Gateway to query information or adjust/control set up points or values in an application or device. This provides greater systems support and functionality from anywhere with cell phone coverage.
Example: There could be a deluge of water in a particular area and the water engineer wants to monitor the water levels in the reservoir over the next few hours. By sending a text via the SMS Gateway he can request the information from the remote device. Once received he can use that information to accurately determine what action is required. The system is designed to promote efficiency and should there be the need for him to turn on a pump to redirect the water flow for a set time, he can conveniently activate the pump switch from his mobile.
