Will likely use meteor burst communications   update 07/28/02

Potential communications technologies include: 
- multiple base-station antennas
- multiple modulation formats
- multiple frequencies - probably spread-spectrum 
- foreword error correction (reduces the signal required by about 100X)

Meteor Burst communications looks like the best solution for very wide coverage, both inside and outside of the United States during the next few years. {Satellite communications may be acceptable after 2005 when more satellite systems are deployed, antennas are smaller, receivers more sensitive, and transmitters are more powerful}  One meteor burst company, StarComwireless.com is expecting to provide 100% coverage of the entire United States by 2003. They also anticipate providing meteor burst communications in many other countries.

The frequency used by Meteor Burst systems is similar to low-band FM radio (40-50 MHz vs. 88 MHz).  Thus places inside of buildings, etc. that FM can be heard the Meteor Burst system will be able to easily operate. Actually, since the Meteor Burst system will use vastly more sophisticated transmission technologies, it will have much better coverage than the FM radio.

Click on this image to see that it requires only 2 or 3 base stations from MCC to cover countries the size of United States or Brazil (Brazil has poor cell-phone coverage)

A less desirable solution is to have communications via a repeater which then has enough antenna and power to communicate with the meteor burst base station. This portable repeater would normally be around the house, but could be carried to the office, on trips, etc.  This solution is not as good as having a stand-alone device, but probably better than having infrequent cell-phone connectivity.

Initial computation of meteor burst RF power levels   updated 07/28/02

CellPhone users = 1,000,000,000 by 2002, 
but they will use 3 different communications technologies.  
Meteor Burst communications, however, will have a single standard which will allow Skyaid Watches to be used anywhere on earth. Because so few will be needed, Meteor Burst communications towers total cost should be less than 1/1000 the total cost of cell-phone towers     added 5/20/01
