Is it possible to convert the router to a different frequency?

Question

network hardware

In theory, is it possible, by replacing any components of the router and writing your own firmware, to make it so that it can be used to communicate on a different frequency? For example, 27 MHz.

Answer 1

In theory, it is possible, it does not contradict the laws of physics.
In practice:
1. you will not be able to use a ready-made chip containing everything in one; you have to develop a circuit from scratch on a bunch of simpler chips; increase in the size of the printed circuit board several times; several chips are more expensive than one; you need to be a high-class electronics engineer (profile VO and years of work in this field); at the same time you need to be a high-class programmer; few people manage to achieve great success in several areas of activity at once (for example, Mikhail Vasilyevich Lomonosov succeeded); you need to spend months developing and debugging the circuit (this also includes studying the documentation), at best, writing the firmware is measured in several weeks;
2. there is a radio frequency service of the Russian Federation; if you use any frequencies without permission and you are caught for this (not the fact that they will catch and not the fact that they will be caught, but there is such a chance), then they will impose a fine on a round sum; if you inadvertently interfere with the military or special services, you can get a criminal record;
Well, ok, specifically, neither warriors nor special services are sitting on 27 MHz, because there is CB, you can use it within the limits on power;
3. For example, at 27 MHz, the transmission rate will be 100 times less than at 2.4 GHz, because the channel width will be smaller.
But in theory it is possible.
By the way. What you are talking about is not called a router, but an access point. The router has other functions. It's just that in household routers an access point is also built in, all this talk about it.
Upd. Why reinvent the wheel when you can attach a motor to a finished bike? I mean, you can take ready-made CB equipment and attach a modem to it. This will not look like Wi-Fi in any way, but you can organize a connection.
