It's the 3G connection used by the public in one of the basement floors of the capital building that has low bandwidth. The capital has its own internal network for congressmen and their staffers, they just don't let random reporters connect to it
Even worse (weirder), the Senate bans electronic devices on the floor. If a Senator wants info, they have to sprint out one of the doors to the lobby where they have an aide waiting with an iPad (usually).
Interesting quite different to the HOC where the result of a division (vote) is read out quite soon after.
I have worked at large 500+ delegate conferences using parliamentary procedures and now they often use electronic systems for both teller and card votes which is much faster
