Wireless communication using an intrinsically safe design for use in a hazardous area

A wireless communication setup comprising:

• a. an antenna receiving wireless signals;
• b. an intrinsically safe primary barrier implemented without a resistor, said intrinsically safe primary barrier comprising a fuse and one or more Zener diodes, said intrinsically safe primary barrier receiving an input power signal in a hazardous area and providing an intrinsically safe power signal as an output;
• c. an intrinsically safe radio transceiver and embedded controller working in conjunction with said intrinsically safe primary barrier converting received wireless signals for transmission via at least one standard module;
• and
• d. at least one intrinsically safe secondary barrier working in conjunction with said intrinsically safe radio transceiver and embedded controller and said at least one standard module to output said converted wireless signal, said intrinsically safe secondary barrier comprising a fuse, one or more Zener diodes, and at least one resistor,
• wherein placing said at least one resistor where a signal exits at said intrinsically safe secondary barrier in said wireless communication setup reduces the loss of power and loss of signal.

A wireless access point comprising:

• a. an antenna receiving wireless signals;
• b. an intrinsically safe primary barrier implemented without a resistor, said intrinsically safe primary barrier comprising a fuse and one or more Zener diodes, said intrinsically safe primary barrier receiving an input power signal in a hazardous area and providing an intrinsically safe power signal as an output;
• c. an intrinsically safe radio transceiver and embedded controller converting wireless signals for transmission via at least a standard Ethernet interface;
• and
• d. at least one intrinsically safe secondary barrier working in conjunction with said radio transceiver and embedded controller and said Ethernet interface to output said converted wireless signal over a wired Ethernet connection, said intrinsically safe secondary barrier comprising a fuse, one or more Zener diodes, and at least one resistor,
• wherein placing said at least one resistor where a signal exits via said wired Ethernet connection reduces the loss of power and loss of signal.
