Heck, there is even 802.11 over infrared light. If you need a bigger address space, the answer in the case of IPv4 is to move to IPv6, also much like the answer to the crowded 2.4GHz spectrum: move to one of the other supported, less crowded bands, especially at higher frequencies, which have inherently less interference. The reason you shouldn't use 240.0.0.1 as an address is, much like the reason you should not use the 2.3GHz band, because doing so can have unintended side effects, both for you and as externalities. Related to your IP example: as you probably know, over 6% of the IPv4 address space is unallocated and (as it is) unused. That's also why we have the 5GHz, 60GHz and 0.9GHz bands, as well as 3.7GHz. The IPv4 Internet is not interferred on by the IPv6 traffic. Using IPv6 does not in any way adversely affect those who don't use it. One of the uses of 2.3GHz is cellular, which may include Internet, voice and emergency services. However, it is, at the very least, rude to operate in a band where you might be causing interference. What makes you think that you have the right to interfere in other's communications because the 2.4GHz band is too crowded for your WiFi? I'm not saying that I 100% endorse, say, the FCC's spectrum allocation policies. Great idea! I hadn't thought about it, but IPv6 should be made illegal or should we just start suing IPv6 operators and make IPv6 protocol illegal?
with this approach you can easily extend too crowded 2ghz band from 2.4-2.5ghz to 2.2-2.7ghz and get 4x more free spectrum for wifi. 802.11y-2008, for which you'll most likely also need a license) or 802.11ah (0.9GHz.)Īren't you already too sick of this kind of bitching? in a way, this is comparable to IPv4 address exhaustion so the ISPs started to offer services over IPv6. If you must operate at a different band (say, because 2.4GHz is crowded where you operate) and 5GHz or 60GHz are not viable options, I suggest you look into 3.7GHz 802.11a (a.k.a. 802.11b/g/n were designed to operate over the 14-channel 2.4GHz band, and using it over a completely different band not only is unsupported by most stations but also performance may be affected. Moreover, it is because of things like this that then we start losing the ability to easily change the firmware in our devices, like the restrictions that TP-Link have started putting in place.Įven if you operate legally, it's still probably a bad idea for a production environment. If you operate illegally, you could be causing interference with other signals in the spectrum (such as cellular), and chances are that you will be caught sooner or later.
However, I beg you not to do this unless you have a license to operate in that spectrum (or are operating in a jurisdiction not requiring it.) You may look at reghack, which is for ath9k.
