Yes, but there is a very big difference. That mesh on the door is part of a
faraday cage that prevents most of the RF from the oven from exiting. They
are specifically built to keep that from happening, and the ovens only
interfere with your router if they operate on the same frequency and are
placed very close to each other. There are directional and omnidirectional
900mhz and 2.4ghz antennas specifically designed for those routers to
create large hotspots. There is a seller every week at the MIT flea market
who has them, brand new. Cities all over the world also offer free 2.4ghz
wifi, many for free, and if you ever get on an MBTA or other regional train
you will see signals from routers come in and go away all over the route.

>> Has anyone set up Arden or a mesh network as a local wireless net through ham radio? Arden stands for "Amateur Radio Emergency Data Network". It's a way to have a wide range personal data network among hams to use in case of emergencies. I'd like to see how much interest there is in the club to make this a club project and build them together. The hardware is low power and relatively inexpensive. I'm sure we have some expertise in the club who can speak much better on it than I. Let me know what you think.
