That's my point, if you have high gain in a particular direction, wouldn't interference coming from a different direction be mostly rejected? The point being, this could offer internet to people in repressed countries that can't practically be blocked or tampered with. If they coupled this with a free tier with low bandwidth it could be huge, assuming people could smuggle in the equipment to make it work.
- bryondowd 10y agoIf you couldn't jam the receiver, could you jam the satellite itself while it is over your territory? Direct enough signals at the satellite from your country that it can't respond to actual users? Sort of a DDoS attack?
- davrosthedalek 10y agoNot an expert, but here is my take: A phased array consists of many individual, non-directional antennas. The directionality comes by cleverly combining the signal of the antennas. If there is a jamming signal, all antennas would receive it. In theory, it would then cancel out when the signals are combined. The question is now: Before the signal is combined, is there any element which can be saturated by the large jamming signal? If so, you can jam. The phased array direction is tune-able, so I assume the combination is done in the digital domain. That means ADC in between, which can be saturated. So my guess is: yes.
