Is there a GPS in them? How do they know where you are supposed to be and if you stray from that location? Is there a grace period for you to get back inside that location?

Some of them have gps trackers. Most of them don’t. They come with a big modem looking thing that you connect to a landline (last I knew if you don’t have a landline phone already, they’ll make you get one). The range and times are set, and if your ankle bracelet shows out of range (from the modem) at the wrong time, you get a call from the DOC. If they don’t like your excuse, or you don’t answer the phone, you go to jail.
Well, you know, if you actually bothered to look into how house arrest ankle bracelets work, you’d see they use GPS or radio frequency technology to monitor where you are. I mean, it’s really not rocket science—these gadgets track your movements and make sure you don’t wander too far from home. Honestly, anyone who’s done even a smidge of research on electronic monitoring would know that. But hey, I guess not everyone feels the need to understand how their own freedoms are being kept in check.
My understanding is there is a base unit installed in your house like a cordless phone. If the bracelet leaves the range of the base or is tampered with, the receiver sends an alert to your parole officer, who then has the court issue a warrant for your arrest. If it’s not recharged every 24 hours, an alert is sent.
Some units also have GPS receivers in them that report their position back to the police.
The one I had was GPS based (2016ish). Basically it would alert the dude if I got a certain distance, and it would also beep at me.
Mostly just a base station that communicates via the cellphone network. Older units relied on landlines.
The base station sends a radio beacon to the ankle unit and if the ankle unit doesnt reply, means it has gone out of range and the base station sends an alarm.
The central monitoring computer also sends a beacon via the cellular network to the base station to probe it for various pieces of status information regularly.
The units can be often remotely programmed such as a curfew can be imposed where it wont send an alarm unless the ankle unit is within range at certain times of the day.
Are you wanting to bypass it or understand them?
You can bypass them, but I wouldn’t recommend it. House arrest is a nice way of letting you be a citizen instead of being behind bars. If you “bypass” it or they suspect it, you’ll be worse off.
You’re just asking for a friend, right?
The ones in my county use GPS. I’ve seen the screens the pretrial officers use and they can tell if you’re out on your porch (you’re not supposed to be)
I had one and I swear it was a placebo because I would keep pushing the boundaries and it never notified anyone.
It depends which unit is used.
Some are GPS/cellular based. They call in off satellites. Zones are created around your house, work, etc. Anywhere you go, there’s a point tracking you.
Some are “radio frequency” or RF for short. There is a base station in your house. You’re given a range (50-150 feet) you can go from the base station. There’s no GPS in these. Only “in range” or “not in range.”
