[...] the nexus itself cannot properly use the skill Electronic Warfare.
An agent running ON the nexus, however, with the right Autosofts,
could.

At least, I think so.

Another note: If you plan on using multiple drones, consider Telematic Infrastructure software.
Hell, yes. Especially, it should count as a Sensor for every drone running it, towards their TacNet contribution needs.

Nonstandard wireless links just make you harder to detect.
.... and it can scan for THOSE, too. Just, as you say, not
easily.

While you're at it with that massive network, consider Tactical Network software. Tacnets are very, very useful...
Yes, yes they are. Even if sensor numbers only permit you to run an R1 or R2 TacNet, those 1 or 2 dice can really be a boost.

Oh, I like this thread. I'm laying down a lot of the tricks I've picked up here and there...
^_^
For those using a nexus as a network-center: consider
leaving it at home. Equip it with a satellite link, then equip a suitable drone with a satellite link and a Repeater. Your expensive nexus never need be in the line of fire, that way.
Altrenatively ...? Run a fiber from your Nexus to a rating 8 Microwave link you can set up in your window (or on a fire escape, or gecko-taped to the wall outside a window, whatever).
Next, we're going to get two nearly-identical drones. Both start of as Aztechnology Armadillos. We'll add [Additional Fuel Tank] and [Gecko Tips] to each of them. We'll also add one [Special Machinery: Microwave Link R8] to each of them.
One, call it Red, gets a second [Special Machinery: Microwave Link R8]. The other, call it Blue, gets a [Retrans Unit] instead.
For delivery of Red and/or Blue, we'll get "Green" - a Renraku Stormcloud, with [Gecko Tips], [Satellite Communications], and [SunCell]. (You'll want satellite ability on your Nexus too, of course, so you can pilot the Stormcloud as far away as you need it to be.)
...
So ... I think you should be able to see where I'm going with this, by now.

You find the tallest point in LOS (and say, within Signal 5 range) of your window-mounted Microwave link. Green delivers Red as close to there as it can safely land, and Red starts trundling it's way straight up the side of that high-ground. Green then returns for Blue, delivering it to a good spot in LOS of Red, and near your job site. Once Red and/or Blue is in position and deploys their Microwave Links, they turn off their regular WiFi systems (except the Retrans unit, of course).
If you need to go further, you can get more Reds, and string them along, daisy-chain style.
Here's the best part .... microwave links are not affected by radio jamming! So, from Nexus to Blue, is
utterly secure; noone can hack in (without physically touching a Red, or your nexus), noone can jam the signal.
...
Oh, and did I mention the Armadillo comes with EW capabilities? 3 points of ECCM (hardware, even), R4 Area jammer, R3 Directional jammer, and 3 points of Signature masking. (By the by, this means that Blue can turn on it's Area jammer, and still have Signal 5 for it's Retrans Unit - 4 jamming, 3 ECCM, original Signal 6).
And Line-of-sight, with R8 microwave designatores, means the only limit is the curvature of the Earth itself. How's THAT, for network security?

Your Nexus could literally be
a thousand miles away. (Blue becomes the weak link in the chain - but with Signature Masking 3, just going radio-dark should save it from a lot of potential threats.)
