Hello, I've been thinking, those satellite downlink and gprs/dail-up uplink, can this also be done with a router board or 2?

Here is my wish to accomplished:
To take 2x Routerboards and plug 2x PC's on each Eth1, and then connect from RB1-wlan1 to the RB2-wlan1, but theres a twist, RB1 have a massive antenna and RB2 have a super small antenna, and its out of range for the RB2, so RB1 cant hear RB2, but RB2 can hear RB1, so basically, its a "1 way link" aka the downlink part
SSID: "downlink"

the uplink part can just be a normal RB1-wlan2 connected to the RB2-wlan2 or it can even be connected using a network cable from RB1-eth2 to RB2-eth2, a "2 way link" like gprs, TCP
SSID : "uplink" or just plain ethernet cable


the biggest problem to my knowledge will be the "downlink" part, because wireless is a 2 way communication, I think... and if the signal gets to weak, it just disconnects, but if it has a dedicated "uplink" why should it disconnect them? because it can still receive UDP packets right from the RB1-wlan2 antenna thats massive? ..so can this be manipulated?

I don't think this is possible. Wireless requires 2-way commuication. Those old satellite modems are specifically designed for this, it's not a standard thing.

just build 2 links, use a routerboard on each and use OSPF to weight the links so that one is A>B and the other is B>A. Set the MTU on the radio links high, then EoIP tunnel between the routers and raise the MTU to 1500, bridge the EoIP tunnel with an Ethernet interface on each side. Done

But how can the wireless client connect to the wireless AP if there is only a 1-way signal between the physical radios? I think the radios at the hardware level require 2-way signal to make a connection, as there is some handshaking that takes place.

I think his suggestion was for a ptp backhaul link..

i have done it that way with the ospf costs, and it works great

I'm thinking the same thing right now?

Naah, my idea is more a point to multi point link using the one radio as a 1 way and the other one also if possible. but only the "downlink" have to be 1 way tho.

EDIT: Its exactly the same method as how a 1 way satellite internet provider works on, that only provides you as a client a downlink connection, but you have to get adsl/or 3g/ dial-up as a uplink


So is there a way to manipulate the hardware level on a routerboard so that it doest require 2-way signal to be able to connect as a link?
