It's very inefficient because every tower must broadcast every message. This is why you can find an archive of pages from the morning of September 11th online, they transmitted unencrypted to a huge area.
So that raises costs and limits the coverage area. Fine for a hospital with 100 idk doctors who need paged, not fine for continental coverage of 100 million users.
- karma_pharmer 3y agoIt's very inefficient because every tower must broadcast every message. No, it's incredibly efficient because the messages are tiny. If you need to send a long message, then you page the person with "you have a long message from XYZ, please use higher-bandwidth mechanisms to retrieve it".
- 01HNNWZ0MV43FF 3y agoSo it only works if you have a secondary communication system that is TX/RX. Within the scope of "How does no-TX work?" it's very inefficient, because the payload is small.
- cdchn 3y agoIts not too bad when you only need 30 kHz of bandwidth per channel.
