WIRELESS

With the growing number of sensors, inputs and outputs increasing in our homes and in industry there is a need to design and produce wireless communication devices and systems that will not need huge amounts of power but also have the ability to handle data. Sensory systems used for business allow for certain companies to have a competitive edge. One of the benefits with intelligent sensor deployment is the ability to monitor and control a process whether it is industrial, commercial and even work flow related. Sensor data can help us respond faster and with more accurate information to changing circumstances. Realtime responses to inside our outside events requires realtime data that is collected and managed intelligently but also in a cost effective manner. The installation of multiple sensors and wireless nodes can now be installed even in locations where power is scarce or even absent. Nodes and sensors can be designed for outdoor use even for use in harsh and even hazardous environments. Intelligent sensory systems allow us to view data that was previously hidden since a fuller appreciation of the status of multiple points was previously unknown. Now that sensors and wireless nodes have become a cost effective solution it is possible to have the information at hand and also an intelligent system that is programmed to respond to changing situations.


    

There are many examples of how wireless networks can be used for energy conservation and equipment or system optimization. The possibilities are countless but just to state the case we can consider how this can be applied in a local supermarket where temperature sensors combined with an intelligent wireless node and system can determine which areas need less or more heat/cool air i.e. the system will balance and optimize the total area so that certain areas will not be using more energy resources than actually necessary for proper function. Temperature sensors for e.g can be installed in strategic areas working through a wireless network to determine the actual distribution of heat or cold within an area so that adjustments can be made. The benefit of the systems would be better resource management,  increased profits (lower overheads) and energy conservation e.g saving electricity costs overall. Specialist companies design sensors, wireless systems and intelligent software to monitor and control the distribution of energy which can be considered a Smart Idea.


    


Since data (even meter data) is increasing year by year there are technologies being designed and implemented using wireless systems but with the ability to handle multiple points and at the same time exhibit a low energy consumption. It is not just industry that is seeing an increase of data but also our homes since many of us have become dependent on things like lighting, heating/cooling and jobs done by various electrical appliances that all consume energy. Zigbee is something that is smart because it has some advantages over Wi-Fi and Bluetooth. One of the advantages is the ability to handle multiple data points with less power consumption. We have to consider the importance of systems and devices monitoring power consumption because if we do not, then we could end up installing solutions which consume far too much electricity and therefore the monitoring and communication systems then become an energy consumption problem that could possibly nullify the purpose of the exercise which is to conserve energy.

The following presentation asks the question "What is Zigbee" and the speaker has been kind enough to fill us in with more of the technical details which should help those unfamiliar with Zigbee to understand the justification for Zigbee implementation.
