No such thing. Ask away!
!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.

With present tech, I don't think so unless the area where you're being tracked is full of equipment that can read the tags (think big RFID readers like you see on the exits of stores). Unless the tracker implant is fairly large to be able to contain/harvest power to power their own active transmitter. Then it would probably be noticeable or at least uncomfortable.
I'm basing this on the fact that we chip pets with passive tags, and those don't seem to suffer any kind of rejection/infection.
The pet chips are nice. Our cat flap detects it and only opens for our cat.
Oh, that's handy.
How many 5g towers are there?
The tower is where you can put an rfid scanner. There’s lots of them, they support power and network, and they aren’t obvious.
Depends, what do you define as 5g? There's multiple 5g frequencies.
There's 5g that's basically just 4g with some extra toppings (low band). I don't really consider this 5g just because there isn't any appreciable difference to the end user.
There's the mid band which gets pretty good range, and much better speeds.
Then there's the mmWave (high) bands which are VERY short range, but insane speeds.

But in cities basically all towers have been upgraded from 4g to the low band 5g. I almost never see my phone connected to good old 4g unless I'm way out in the middle of nowhere. (USA)
OP is asking if it’s possible to track someone.
I’m suggesting that passive rfid is possible with transmitters, and there are 5g towers in lots of places, enough to track a person if a government was inclined. I see them every block in many city business centers.
Aa key trait of RFID is that it's passive and only has a range of inches to maybe 5 feet. Even mmWave towers are typically out of that range, plus it needs active power. Tracking someone using their (actively powered) phones cell signal is incredibly easy, even with 4g. It's shifting through all the data that's hard and time consuming.
Identifying someone using 5g's radio frequencies would technically quality as Radio Frequency IDentification. When people talk about RFID they're typically referring to those passively powered key cards. Those key cards barely work when they're an inch away from the object, let alone 5 feet away plus 0.5 cm of RF absorbing skin.
As I stated previously, toll booth rfid work at 20+feet and 80+.
