Should be easy, and will not affect your existing or future 802.11b communications at all, except to possibly improving them. Many posts I have read here, mistakenly believe that this will lower the power (and thus the bit rate) of their 802.11b communications (in band). According to the 'Wireless News' article, this requirement only affects 'out of band' emissions (and rightly so). If equipment is causing interference, it must be fixed - thats what out-of-band emissions are, interference. (Even if satellite radio sucks, and should be interfered with.)
Why will it be easy; it simply requires a better filter in the 802.11b equipment. This may sound like more money, etc. In reality, most of these devices are using digital filters. Just change the filter algorithm (the software), and you have solved the problem, and quite possibly improved the 802.11b communications as well. If the filtering algorithms are hard-coded into the chip, than it requires a slightly redesigned chip. These chips are being redesigned all of the time; what is one more bug fix? BTW, reducing the power of these spurious emissions, MAY, increase the power available for the intended 802.11b communications.
My guess is that most equipment that is up to 802.11b or bluetooth standards have little or no problem at all, and may already meet this standard. There is a lot of cheap 2.4GHz garbage on the market, and it will be this stuff that must be (and should be) fixed. Unfortunately, a lot of this garbage will take more fixing than simply modifying a digital filter. BTW, the FCC is not requiring you to turn in all of your purchased gear for testing and destruction.
None of this will kill, or even harm, the wireless industry (unless Mr. Leary believes that prices will go up or demand will somehow go down. Can't see it happening in this industry, where prices continue to fall daily.) It may put shoddy manufacturers out of business, which will only improve our wireless products. Or perhaps Mr. Leary believes that wireless is the only important industry, and as such should be allowed to go back to spark-gap transmitting technology?
Now, fess up; how many of you have have wireless access points in your car, with linear amps attached? |
