One guy was asking me to build a Firmware for him, which would support 2.3Ghz range.
I just surprised that I never saw something like that, after that, I saw proof which was real.
Then I searched Google if I can get anything about it. But I'm not lucky yet.
Do anyone know how to build Firmware that supports 2.3Ghz to 2.7Ghz?
That guy router was, TL-WR841N v5.x.
Thanks in advance.
DD-WRT has a feature called super-channel which unlocks some frequency ranges.
Using 2.3GHz may violate local radio frequency regulation.
Do you have any information about the country targeted by your build?
You may look at reghack, which is for ath9k. 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.)
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. 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.
Even if you operate legally, it's still probably a bad idea for a production environment. 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.
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. 802.11y-2008, for which you'll most likely also need a license) or 802.11ah (0.9GHz.)
misleading information
aren'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. 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. or should we just start suing IPv6 operators and make IPv6 protocol illegal?
but you can't explain why
they've been limited to operate over the 14 channel band, not designed
there is no completely different band, it is all 2ghz band. how do you think these APs with 3 or more antennas could get 300Mbps of throughput? running on a single 22mhz channel?!?
look what i've discovered: https://github.com/openwrt/openwrt/issues/229
atheros stations support this, ralink stations can detect signal on 2.3ghz but driver work is yet to be done

misleading information
[/quote]
reghack is the closest that I could find that is comparable to DD-WRT's super channels. A closer look at it, and I don't think that it enables the 2.3GHz band. However, it may still be useful for enabling it (perhaps requiring some patches or as a starting point.)
Great idea! I hadn't thought about it, but IPv6 should be made illegal </sarcasm>
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. However, it is, at the very least, rude to operate in a band where you might be causing interference. One of the uses of 2.3GHz is cellular, which may include Internet, voice and emergency services.
Using IPv6 does not in any way adversely affect those who don't use it. The IPv4 Internet is not interferred on by the IPv6 traffic. That's also why we have the 5GHz, 60GHz and 0.9GHz bands, as well as 3.7GHz.
Related to your IP example: as you probably know, over 6% of the IPv4 address space is unallocated and (as it is) unused. 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. 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. Heck, there is even 802.11 over infrared light.
Except I did. I said: lack of support (which makes deployment difficult; proof of that is this very request and the seeming lack of information on this subject), potential performance issues (from abusing the protocol to do something it was not intended to do; for example, no transmit spectrum mask exists for 2.3GHz) and the fact that better alternatives exist.
Are you claiming 2.3GHz or 2.7GHz performs at least as well as 2.4GHz under all circumstances? Would you care to back this up? Normally you design something taking into account the constraints you have. Things like channel width, modulation, noise reduction, etc. do depend on the wave characteristics that you have. When you use something in a way it was not indended, you get into uncharted territory. It may very well function better, but normally it does not.
So you're saying these APs with 3 or more antennas get 300Mbps by... using multiple channels... in the 2.3GHz band? The part of the world where you live is obviously alien to me, but where I live, these APs generally use a 40MHz channel (which is two contiguous 20MHz channels) in the 2.4GHz band. Also, where I live, it's rare to see such 40MHz channels because these APs are not supposed to use such wide channels when they would cause interference with neighbouring APs, which happens often as, both where you and I live, the 2.4GHz band is crowded.
Luckily, if you need high throughput, 5GHz can provide it and it has pretty good marked penetration.
because you are unable to perform a simple research using google: https://forum.openwrt.org/viewtopic.php?id=70093
maybe i still have proof you're wrong. will post an image if i find it.
When you use something in a way it was not indended, you call it a HACK
Of course it does, otherwise it would be pointless to waste so many efforts convincing people.
I know DD-WRT has some features, but that guy asking me to build something like that in OpenWRT. I just confusing if DD-WR possible why not in OpenWRT. Yeah, I know security concern about, Let's ignore that part because that guy has no worries about it, and I need to learn this part as I never saw something. So anyone has an idea to make OpenWRT build with 2.3-2.7Ghz or whatever except 2.4 and 5Ghz
There are no simple standard ways to achieve what you want. In order to use nonstandard frequencies, you have to modify the ath9k driver.
How to do that? Any guide available to follow?
I have modified the 2 patches and applied to my wr841nd v11. But the channel list is ever the same, only 13 channel. Should be i have to make other modification in the art partition?

}Hi,
interested topic. There is an ham amateur radio project that mantains patches for openwrt chaos calmer
https://www.arcman.de/pub/patches/arcman_patches_20160203.tar.gz. These patches enable 2.3 Ghz (ham radio) for atheros devices
Patches are working at least for openwrt cc revision r49480, with last cc source are broken due of new hostpad version.
It could be a useful start point to implement ham radio support (or extended channel in general) in lede project...
D.
Any progress??
While this is IN FACT illegal without a license or Special Temporary Authority from the FCC in the US...I will refer you to 2 resources:
http://www.broadband-hamnet.org/
I know for a fact, there have been some Amateur Radio Operators able to access Channels "-2," "-1" and "0" (which channels are completely within the 2.4 GHz licensed Amateur Radio band). I am aware, this is on the other side of the band than you're interested in (below 2.4, not above). Nonetheless, I spoke to the head developer of AREDN to get the information patched into OpenWRT, she never responded to me.
I'm also not certain that either project uses a public code repo. Both projects seem highly rewritten from a version of Kamikaze. Broadband-Hamnet is in fact a stripped-down OpenWRT.
Yes, it is true that there are licensed uses for bands that are not in the regional "license-free" bands. Unless you have a license for those bands, you are not permitted to operate in them. In the United States, unless you have a license to modify radio equipment for use in those bands, it is illegal to do so.
The US Amateur Radio Service does permit certain of its licensees the ability to operate in certain of those bands, with the restriction that the data must not be encrypted, and may not be used for any commercial purpose. So, for all practical purposes, even with that type of license, those channels are "useless" for typical use; no encryption on the wireless, no connecting to commercial websites, no TLS,...
It should also be noted that 2.4 GHz while not licensed, is regulated for all users in the United States. The rules are defined in Title 47, Code of Federal Regulations, Part 15.
users manual or instruction manual for an intentional or unintentional radiator shall caution the user that changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment
I have ham license in my country (India). That's why I'm trying to unlock these bands.
brother there is I'm from Cuba I'm looking to put my router TP-Link WR740N V5 channels from 2.3Ghz - 2.7Ghz and I have OpenWrt 18.06.1 r7258-5eb055306f put.Ask and a way to do it
At least from what I have read, Cuba permits only channels 1-13 on the 2.4 GHz band. As a result, fulfilling your request would go against the rules for this forum.
but I am a ham radio, in Cuba nothing is published with respect to the channels here people put the nanos and other ubikiti equipment in compilance test. please can you allude me I just want to unlock all the frequencies of my router so I can connect to a bullet What I have close to my house. that uses the frequency 2312 I think
