Alan it is plain you have no understanding of the issues or the scale of the technology involved.
There are limitations and laws of phsyics that simply do not change.
you would not obvioulsy be aware of the massive slabs of bandwidth that are required to support the relativly short range relativly low reliability communication used in our mobile phones....or that the transmission range of the current and comming digital mobile phones is dramatically less than the old analogue system.
tell me....that sat phone.....if it was on line continuoulsy.....how long would the battery last and how much would it cost.
OH..and that satelite phone.....will it work..GUARANTEED in every country in the world and every ocean in between...even 2000Km from the nearerst land.
Tell me of any other communications system regardless of price or technology operating on the same system that is guaranteed to work any time of the day or might in the middle of any of the great oceans.
OH and that mobile phone.....can it sit....unused and uncharged for 5 years strapped to the bulkhed of a boat in all weathers and be GUARANTEED to work.
Everthing about an EPERB is tightly specified by international agreement and is GUARANTEED to work.
My 4G mobile phone isn't even guaranteed to work in my kitchen.
As for the old mobile phones...I still have my Motorola 8723.. it cost me over a grand when it was new...let me tell you it was far more reliable and durable than almost every phone I have owned since....even it in its day could not touch a EPERB for durability and reliability.
The ability to locate and identify a single
beacon among all those in use in the world anywhere on the face of the plannet is a pretty clever achievement......
Your comment is a prime example of how much people take technology for granted.
cheers
