Other approaches[ edit ] The choice of competitive strategy often depends on a variety of factors including:
The United States is the only country that distinguishes between the "upper" and "lower" L-band.
All passengers on board the and the two pilots in the Cessna were killed. Seven people on the ground were killed by the falling debris, and an additional nine persons were injured. Both aircraft received voice notification of the approximate location of each other, however the National Transportation Safety Board determined that the probable cause of the crash was the failure of the to maintain visual separation with other air traffic.
One of those killed in the crash is a friend of Dr. It is eventually granted U. Patent 4, in The FCC defines it this way: Spread spectrum is a term applied to communications systems that spread radio frequency energy over a wide bandwidth by means of an auxiliary spreading code.
The spreading of the bandwidth can be accomplished in many different ways and the systems are usually classified by the type of spreading technique which they employ. They are commonly referred to as: The spreading or dilution of the energy in spread spectrum systems over a wide bandwidth results in several possible advantages: While we do not anticipate that spread spectrum will replace other types of modulations, the unique characteristics of spread spectrum offer important options for the communications system designer.
Satellite services for individuals? Geostar Corp of Princeton, NJ, proposes a satellite-communications system that would permit persons to send messages via satellite, using devices no bigger than pocket pagers.
The system will locate the exact position of the sender, and handle messages of up to 36 characters.
In its application to the FCC, Geostar states that a person confronted by a mugger could press a single button on his communicator. That would send out a signal that would go to three satellites in geostationary orbit over the Equator, and from them back to a computer on Earth.
The computer would determine instantly the exact location of the sender by noting the difference in the time it takes for signals to reach the computer from the different satellites.
It would then notify the nearest police car or station. The system would also be valuable to hunters and others lost in the woods, and would be of great value to trucking companies, who would make large savings if they could determine the location of - and communicate with - their trucks at all times.
The proposal has not found favor in all quarters.
The cellular radio services - some of whose alloted frequencies Geostar proposes to use - are particularly unhappy. An article appeared in the September issue of Data Communications magazine: The relatively low-speed scheme is a sort of data version of existing analog cellular radio technology, but on a nationwide scale.
The project is the work of Dr. O'Neill was granted an extensive patent by the U. Patent Office last year that, his colleagues say, covers 49 new technological claims. Many of these, relat ing to satellite communications, will reportedly make the scheme possible. The Geostar project was undertaken to provide a new, reliable, and highly accurate means of determining the exact positions and altitudes of commercial airplanes.
Their locations will be tracked and compiled by a large central computer, which will facilitate air traffic control and, presumably, all but eliminate the threat of mid-air collisions. The transceiver constantly listens for "interrogation" messages, sent via satellite from the central computer, and responds on a regular basis with a message that includes a unique identification character sequence.
The three satellites each receive the response and relay it to the ground-based computer, which, based on the propagation delays of the responses, triangulates the plane's longitude, latitude, and altitude.

The calculated location, Geostar claims, will be accurate to within 50 feet. Realizing that the scheme would also support locating mobile, ground-based targets - as well as two-way digital data communications from anywhere - Geostar went back to the drawing board and enlarged the scope of the plan.
O'Neill says that plans are already under way by fleet owners and traffic managers to use the service to keep track of trucks and other ground vehicles.
Geostar conducted a test here recently of its data transmission capability, using leased satellite transponder capacity from another carrier. Geostar does not expect its own three satellites to be launched until Field trials have reportedly established that the scheme works.
A portable data-entry terminal, transmitter, and power pack were employed in the tests. However, Geostar expects that by an integrated unit containing all of the components, including a miniscule two-inch dipole antenna for both receiving and transmitting, will be no larger than a carton of cigarettes.
This unit, says Geostar, will be powered by a wristwatch battery. A great deal of power is not required to transmit to, or receive from, a satellite, but the Geostar plan represents a unique miniaturization of both antennas and power supplies.Consider all the advantages and disadvantages of business expansion before investing in growth Growth through product and service development ; Growth through sales ; Growth through technology ; Growth through strategic sourcing Advantages of growth.
