Simple transmitter-receiver device like Smarttag

[Julian_M]

Hi,

I have a 5 year old child in school. My car needs to go inside school compound precisely when they come out of classroom so I don't have to circle for 30 minutes. The dismissal time can be off by 5 to 10 minutes. I have tried letting him use the Samsung Smarttag where he presses the button when coming out of classroom (they are held in one place inside). But my Smartphone doesn't always receive the Smart Tag signal which needs other smartphone in the vicinity.

I need a simple device based on radio waves only (not wifi or bluetooth or needing other smartphones). So when he pressed it, my device would alert instantly (no delays). Walkie talkie is so big. I just need a simple button. Please give suggestion of ready made devices. Thank you.

Ask the teacher/supervisor to enable a smartphone, so other children can use the same Samsung Smarttag2 system reliably.

Get a Restaurant Pager System. Give the child or the teacher the transmitter.

Solve the problem for a class of 30. Supervisor operates the transmitter, you swap your child for the pager at the pickup point.

5 year old students are not allowed smartphones in class. And the teacher is so busy to operate the transmitter. Because during dismissal. The teacher is busy lining up 20 students to go to waiting area. The kid can easily press the button. Maybe the Restaurant alert device will work. I'll look into it.

If others have other idea. Maybe another alternative for the restaurant alert system (which has 4 receivers and I need only one). Please let me know. Thanks.

Oh. Problem for restaurant pager is the transmitter is so big and has many buttons and numbers (see below). I just need a transmitter with one button only.

5 year old students are not allowed smartphones in class.

Then the teacher's smartphone needs to be turned on, to relay a student's Samsung Smarttag2 message to their parents phone. Does the teacher not have a phone that can be enabled and turned on?

If the distance is below 1000 ft, you have the portable caregiver pager, for example: https://www.calltou.com/collections...aregiver-pager-call-button-nurse-rechargeable

For distances up to 3300 ft, you have the portable intercom, for example: https://www.calltou.com/collections...able-1000mah-battery-vox-ideal-for-caregivers

IMO, most things like that are very optimistic about their range and can only come close if there are no walls in between. A signal from inside a school building might not get out.

Does anyone know of a 4G/LTE sos/panic button, one where you can insert a simm and put the number where it can call when a button is pushed? Not just SMS but call because SMS has delays. There is a fence and a small building in the path which can block any wireless bell unit or even wireless income I nearly bought.
