Wireless Enterprise Solutions – Eliminate Low Or No Signal Problems On Your Cell Phone Effortlessly

Imagine arriving for a business meeting at a facility where your cell phone signal is extremely low or not present at all. Such a situation would surely affect your decisions when choosing future meeting locations or conference sites, as business today simply does not function in the absence of cellular signals. This is where a cell phone signal booster comes into the picture. This innovative device is simple in concept but complex regarding its specific capabilities. More commonly known as a Bi-Directional Amplifier (BDA) they are engineered to vastly improve cell phone signals in poor coverage areas, and along with proper system design will not disturb other cellular phones or towers. BDAs use existing cell phone signals found outside a facility, then distributes that signal indoors having no coverage. A cell phone signal booster may use a relatively simple, small array of coax fed antennas, or may use a complex active Distributed Antenna System (DAS) depending on factors such as size and shape of the building. Even though a cell phone signal booster is a key component in any system, the indoor antenna system is equally critical to assure that the in building wireless signals arrive to the cell-phone just as clean as if the user were outside.

Gone are the days when you struggle to find a sweet spot or get near a window to reliably use your cell phone. Properly designed DAS solutions can provide full bars almost everywhere you need your cell phone. The cell phone booster is the basic building block needed to gather outdoor signals, whether 2G through 4G, then repeat those signals to indoor coverage areas. Properly designed distributed antenna systems can deliver signals from multiple BDAs supporting multiple frequency bands and multiple wireless service providers simultaneously. Such wireless solutions take advantage of signals from various directions using multiple cell phone towers.

Any system using a cell phone booster must be carefully designed as it uses frequencies that are licensed for use by cellular service providers and can cause great harm unless used correctly. Such mistakes can bring trouble with both the license owners and FCC, so care must be taken to use a trusted and capable system integrator. This is especially true for vendor-neutral systems where multiple air-interfaces are required and capable of supporting any user with voice or data. Lets face it; a phone without signal is useless. A cell phone booster can transform expensive paper-weights into profit producing tools. Dont frustrate, or worse yet lose another client due to weak signal and dropped calls. A cell phone booster, or possibly multiple boosters, with a properly designed Distributed Antenna System can bridge the cellular wireless gap, providing the critical wireless infrastructure that every business needs to compete in todays fast moving information driven economy!

Why To Use Bulk Plant Emergency Stop Industrial Wireless Controls

The need for automation in the industrial sector has sparked an interest in the field of industrial radio remote control communication. Imagine you run an industrial plant and want to automate the entire manufacturing procedure. When automation is done, it always has a risk of malfunctioning or the temperature exceeding the threshold limit.

Now remote communication can send data to any electronic device and help in complete automation of the procedure. If you have a system that connected to the plant, a simple message can de- active the entire production process. It might be a very primitive example. However, consider the amount of flexibility an organization will have in the industrial wireless controls automated world.

Industrial radio remote control communication is primarily done with the two devices adhering to certain protocols during data transaction. Now communication protocols are certain rules and regulations a device that should follow when it transmits and receives the data in a particular format.

Now bulk plant wireless emergency shutdown systems are developed to eliminate costly hard wiring of fixed location emergency stop switches. These wireless E-stop switches can be installed within the plant facility and communicate with one receiver or controller unit. Basically these systems will work in conjunction with obtainable, hard wired, manual E-stop switches and plant safety controls. Now the operator worn E-stop remotes can also be added to these systems.

Emergency stop transmitter has some wonderful specifications through which the operator can know details about.

1.The system is low powered, intrinsically safe devices that suitable for use in hazardous environments.
2.Now all systems are CSA, CE, and FCC approved.
3.Basically, pressing the Emergency Stop button causes the receiver/controller unit to trigger a plant shut-down. The device cannot be rebooted until the E-Stop button is pulled out and a manual receiver/controller reset is performed.
4.E-Stop buttons are dual contact. It has dual channel and comply with global E-Stop switch requirements.
5.The systems will fail safe, triggering an automatic E-Stop with any loss of main line electrical power supply to the receiver/controller unit.

The emergency-stop receiver or controller has some special features that includes;

1.This is easily interfaced with electrical, pneumatic, nitrogen, or mechanical plant shut-off equipment.
2.The systems will operate with 12/24VDC or 120/240VAC power supplies.
3.Actually, the receiver/Controller outputs can specified as 12/24VdC, 120/240VAC, dry contact, RS232, or J1939.

Industrial wireless controls communication protocols help the device to transmit the data with a particular encryption code with help only certain devices to decrypt and receive the data. Now mobile devices and radio modems operating on a particular frequency will be able to receive the data and process further.

In industrial automation, the data can be used to initiate data communiqu. In a system, the data can be sent to the control center for further processing that is based on certain algorithms. Bulk plant E-stop systems are really easy to use and maintain. They are considered as efficient wireless controls that maintain the co-ordination of the total system.
