Wireless communication, or sometimes simply wireless, is the transfer of information or power between two or more points that are not connected by an electrical conductor. The most common wireless technologies use radio waves. With radio waves distances can be short, such as a few meters for Bluetooth or as far as millions of kilometers for deep-space radio communications. It encompasses various types of fixed, mobile, and portable applications, including two-way radios, cellular telephones, personal digital assistants (PDAs), and wireless networking. Other examples of applications of radio wireless technology include GPS units, garage door openers, wireless computer mice, keyboards and headsets, headphones, radio receivers, satellite television, broadcast television and cordless telephones. Somewhat less common methods of achieving wireless communications include the use of other electromagnetic wireless technologies, such as light, magnetic, or electric fields or the use of sound.
Wireless communication is a broad term that incorporates all procedures and forms of connecting and communicating between two or more devices using a wireless signal through wireless communication technologies and devices.Wireless communication involves the transmission of information over a distance without the help of wires, cables or any other forms of electrical conductors.
Wireless communication can be used for cellular telephony, wireless access to the internet, wireless home networking, and so on. Other examples of applications of radio wireless technology include GPS units, garage door openers, wireless computer mice, keyboards and headsets, headphones, radio receivers, satellite television, broadcast television and cordless telephones.
Why Wireless Communication in construction?
According to the new market research report “Wireless Power Transmission Market by Technology (Induction, Magnetic Resonance), Implementation, Transmitter, and Receiver Application (Smartphones, Electric Vehicles, Wearable Electronics, and Furniture) and Geography – Global Forecast to 2022”, the wireless power transmission market is expected to be worth USD 11.27 Billion by 2022, growing at a CAGR of 23.15% between 2017 and 2022. The factors that are driving the growth of the wireless power transmission market include the convenience offered by and consumer preference for wireless connectivity and need for effective charging systems. The market has also witnessed significant developments for wireless charging as many start-ups have developed the products based on laser and microwave technologies, which can charge multiple devices at a time.
The construction industry is booming. According to Dodge Data & Analytics, 2016 is going to be a $712 billion year. To take advantage of the boom, your employees in the work zone need to work at maximum efficiency.
Boosting construction productivity increases your overall efficiency. You can take on more projects to earn more revenue. When everyone is working smarter, your bottom line is the beneficiary.
Many sources accurately point out that improvements to jobsite layout, equipment maintenance, and materials management will boost productivity. But the greatest return on your productivity investment comes from enabling seamless team communication on the jobsite. Productivity suffers without clear communication.
When wired communication can do most of the tasks that a wireless communication can, why do we need Wireless Communication? The primary and important benefit of wireless communication is mobility. Apart from mobility, wireless communication also offers flexibility and ease of use, which makes it increasingly popular day – by – day. Wireless Communication like mobile telephony can be made anywhere and anytime with a considerably high throughput performance.
Another important point is infrastructure. The setup and installation of infrastructure for wired communication systems is an expensive and time consuming job. The infrastructure for wireless communication can be installed easily and low cost. In emergency situations and remote locations, where the setup of wired communication is difficult, wireless communication is a viable option.
With wireless communication, supervisors can deliver clear instructions at the outset. Craftspeople can ask questions at any time and receive immediate answers without having to stop work. Teams complete the job right the first time. Fewer mistakes on the job result in higher quality; the level of quality you envision in your original plans and work hard to deliver at project completion.
Wireless communication also eliminates the need for hand signals and lets you control the conversation. Each team can have their own channel to talk to each other. And the boss can talk to them all.
Only wireless communication systems give you that level of control in your work zone. They make all construction crew members more productive and greatly improve your chances for success.
Wireless communications let employees work without interruption, resulting in fewer unproductive hours. No one has time to waste chasing down a colleague on the job site. Equipment operators can clearly hear and execute instructions in real time without shutting down equipment. Supervisors can alter plans on the go with confidence that crew members whose jobs are impacted by those changes are clear on new instructions.
Two-way radios can be cumbersome if you’re trying to communicate while actually working. Noise-cancelling earmuffs or foam ear plugs require a worker to use a hand to lift the headset or remove the ear plug to hear instructions or listen to the surrounding environment. With one hand off the wheel or a jackhammer, saw or other tool, work is either stopped, inefficient, or unsafe.
Wireless communication frees up every worker’s hands, increasing mobility and efficiency. The flagger can hold a sign, wave traffic through, and respond to the crane operator all at the same time. The crane operator can communicate with his signaler and the flagger while maneuvering his load. And the truck driver can position her vehicle in the ideal location to land the crane’s load.With wireless communication, all hands are always on deck.
In this regard TALK PRO WIRELESS SERVICES is giving a great advantage for wireless communication system in India.
Safety Factor
Recent advancements in technology provide a solution to this problem in the form of portable wireless communication systems. At the heart of these systems, wireless headsets reduce background noise and allow work crews of almost any size to communicate clearly, even on opposite sides of a work site. Properly designed, they also leave the worker’s hands free.
Wireless headsets are designed to fit completely over the ear for hearing protection and are outfitted with a boom microphone and ear speakers to allow voice transmission and reception through a mobile base station using a wireless signal. When coupled with a mobile base station, they create the equivalent of a local audio network wherever they are deployed. In more advanced systems, the local audio network itself can be connected to a remote work site or dispatch center by means of a mobile radio interface
Ideally, radio-interface systems should also allow crew supervisors to select which headsets will be allowed to broadcast over the radio (usually by a push-to-talk button on the headset) and which will provide “local only” communication. Configurability greatly reduces the amount of “chatter” that can occur with systems that do not offer this functionality. Up to 60 users can communicate in an efficient and orderly fashion on a configurable wireless system, making it an ideal solution for even the largest work crews.
Conclusion
The introduction of Internet and communication technologies has seen the urgency in the expectations of people within the industry to have access to the latest information produced at any point in the project life. These expectations reflect the increasingly competitive pressure within the construction sector to deliver quicker and cheaper solutions. It also reflects the increased electronic awareness that internet use has cultured, realising a one-stop ‘information on demand’ medium. The invention of handheld computing device enabled with a suitable wireless capability has proved a valuable innovation which reduces travel costs, increase operative efficiency, and speed data transfer. Data can easily be keyed on site and communicated wirelessly to the office computer. This information can further be uploaded on from the computer to the internet or extranet enabling faster and quicker process which reduces times.Mobile communication technologies therefore can strategically be implemented to reduce cost and increase returns on investment. There are many applications of mobile communications in the construction industry. This report however focuses on the impact of mobile communication technologies in the construction industry.
