Also, knowing that the 5 GHz band has been less heavily trafficked, more and more small businesses have been moving their wireless networks to that frequency, expecting to find zero interference and a more reliable Wi-Fi network. While it’s true that fewer devices currently operate on 5 GHz, there are enough now to cause some interference. Wi-Fi network components transmit data on this band along with radar and digital satellites. There also are a handful of point-to-point and point-to-multipoint devices that exist that transmit at 5 GHz. The FCC's new Spectrum Dashboard is actually a nice tool for looking into who owns licenses in different frequencies and for different services in your area. http://reboot.fcc.gov/reform/systems/spectrum-dashboard > > On 6/13/2012 11:15, Michael Butash wrote: > > Tons of things do, old cordless, legacy proprietary wireless > mice/keyboard/remote controls, ir-replacements, random bits of > pseudo-ethernet devices (sonos audio system comes to mind), bluetooth, and > most anything else "wireless" defacto runs in 2.4ghz, including 99.9% of > wireless computers blasting out torrents (literally) of packetized and > attuned rf. > > I won't reiterate a plethora of wireless bits, but 2.4 bites for lack of > total non-overlapping channels, it's more or less the cesspool every device > defaults to, good, bad, or ugly. > > I did read somewhere that supposed there was a 3.6ghz spectrum released > for general consumption to give more network band, and there's always 5ghz, > which is preferred with 802.11a, or 802.11n that can use either band. > > -mb > > > On 06/12/2012 11:06 PM, Derek Trotter wrote: > > It's unfortunate that someone deliberately comes up with something like > this that adds a lot of junk to a band that's already full of sources of > interference.
