This is part of the reason why I've been considering getting a one-way pager and leaving my mobile phone off or in airplane mode.
This way I would only need to take my phone out of airplane mode if I happen to be in a location where I can't use another phone to return pages.
- simoncion 11y agoA pager would have the same triangulation-via-cell-tower and social-network-analysis-via-page-history vulnerabilities, right?
- jf 11y agoNot a one-way pager? My understanding is that one-way pagers (POCSAG, etc) pagers are "receive only".
- richardwhiuk 11y agoThey still need to communicate two way to the cell tower to receive pages. Pages don't get flooded to every cell all over the world!
- upofadown 11y agoOne way pagers only work in a particular area of the world. In that area all the transmitters send all the pages. Such systems do not scale all that well and as a result getting pager service over a wide area can be fairly expensive.
- doctorshady 11y agoThere's a few nationwide pager networks out there; they're quite easy to build without the task of making communication two way. Just set up a hundred or so watt UHF transmitter at an antenna farm, feed it with PSK or FSK from a satellite receiver, and boom! You just covered most of a large city.
- upofadown 11y agoCorrect. That is probably why pagers are so popular with drug dealers. The downside of a one way pager is that there is no way to know if the message got through. If you are in an elevator (or wherever) you simply never know of the page.
- Aloha 11y agoa one-way pager is very literally one-way its the same as being unable to track a car radio.
- simoncion 11y agoFolks in thread: Thanks for the info on one-way pagers. That's interesting stuff!
