Alternative Frequency Wireless Ethernet Devices?

Posted by Cliff on from the mutant-devices dept.

rtgree01 asks: "Do Slashdot readers know of any wireless ethernet devices that are not 900 MHz, 2.4GHz, or 5GHz. This is for a project that will be in an extremely harsh EMI area (thousands of V/m at those frequencies). Also, to make things even more impossible, line of sight is not available, even though the range for this system should be 30 feet max. Some of you might suggest to stick with a standard wired solution, but that is not optimal at all. Any suggestions would be greatly appreciated."

    I am curious what environment that you need this at where you u have large amounts of voltage and signal, yet do not have control of the area? Off hand, this makes no sense unless this is needed to get around something that you are not supposed to be in. The implication is that you have a fence with high voltage and windowless wall to communicate through, like a prison. Otherwise, I suggest if you have permission/autharization, then use fiber (30 ft) or use laser.

    I prefer the "u" in honour as it seems to be missing these days.

    Lasers modulated by the output from an ethernet port or serial port with PPP, redirected with mirrors?

    Not if the e.m. noise is at the frequency of the light. :-)
