I'd be interested to hear if anybody can squash this one for me. Some questions explain 'what the Train-Station is' and 'how he got there' (he touched the source and ooh that caused him to be somewhere between the real world and the matrix) but these are abstractions, abstractions don't work until there's hardware to implement.
When I was growing up this plot jump made perfect sense because I could invoke the following logic: "This movie is cool, I like it."
I'm rewatching it as an adult after a college education, and I'm wondering how on Earth Neo could actually be plugged into the train-station without being connected to something via brain-needle. Kind of a huge plot hole here. This all starts in movie #2 when he's like "wait, something's different" and somehow he fries three sentinels with his mind. Trying to reconcile these two components of the trilogy, I can only think of the following, fragile solutions:
All the machine-grown humans have some latent wi-fi-esque hardware integrated into them.
I find this answer shaky and unsatisfying upon investigation.
A machine would not integrate wi-fi hardware into a human that it expects to to remain in a static location with a hard-wired connection for its entire life.
One might try and argue, "Well what if the cable fails? Then there's a backup!" But if that is the situation, A far more elegant solution is to have the back-end system be of two hard wires, a primary and an auxiliary. In the event of a primary failure, load is shifted over to the auxiliary, and some IT request ticket is raised to replace the faulty-primary. (If you laughed at the IT request thing, the entire Matrix Trilogy is an IT ticket request essentially).If the machines knew humans would escape, as explained by the Architect, it is unlike a machine would provide so many facilities for humans to enter the matrix, as opposed to bottlenecking them all through their phone-terminal entries.
Bottlenecking means better managability, cost-free. Sure, they "broadcast their pirate-signal" to the matrix, but any way you slice that, it becomes strange and not-machine-like to provide both a wifi/hard-link networking solution for its human users. The broadcasting thing is more likely workflowed as such:
brain-hw -> hard-link -> 'wifi'-broadcaster -> matrix-terminal -> matrix as opposed to the brain hardware already being capable of wireless activity, and the cables being somehow like guitars to an amplifier.
All machines operate on brain-waves or something, and neo has unlocked some latent brain-wave-amplifier hardware that was integrated in him at birth, thus being able to fry squid telepathically and enter the matrix/train-station.
Again shaky, for similar reasons as (1).
Some kind of wireless hardware was installed in Neo during his muscle-atrophy days in the original film, and it is somehow new technology that nobody knows about
Probably the most plausible answer, but still not very satisfying. This could also explain why whats her face says to trinity about neo that she's "never seen anything like this " (regarding the neural patterns of being jacked-in), if it were such a cutting edge technology, then of course it's plausible that she's not reading the Zion Herald and didn't hear about the new wi-fi implant for your brain-stem. No more of that painful 'jack-in' headache!
Anyway, I could not find any explaination on how they're expected to achieve this, so I guess its all up to interpretation.
