Abstract
Multiple copies of a software or operating parameter change are broadcast using a wireless signal to a mobile electronic device. Broadcasting multiple copies increases the probability that the mobile electronic device will receive the change without error. The number of copies broadcast is a function of the expected probability that the device will receive one copy without error and a desired probability that the device will receive the change without error.
Claims8
A method for reliably transmitting information to be stored in a mobile electronic device, comprising the acts of:
- broadcasting multiple copies of data, wherein the number of copies is calculated as a function of an expected error reception rate and a desired fraction of mobile electronic devices to correctly receive the data to achieve sequential exponential improvement in reliability of reception;
- receiving at least one copy of the data at the mobile electronic device;
- and
- using the received data to change information stored in the mobile electronic device;
- wherein the actual number of copies that must be broadcast to ensure the desired fraction of receivers correctly receive the data is calculated as:
- N≧1+|log P/log(l−R)|, where N is the number of copies transmitted, where P is the desired fraction of mobile electronic devices to correctly receive the data and R is the expected reception error rate, and wherein the likelihood of reception increases to a high level with the multiple broadcasts.
An information delivery system for transmitting to mobile electronic devices comprising:
- a transmitter which broadcasts to the mobile electronic devices a plurality of copies of data, wherein the number of copies is calculated as a function of an expected reception error rate of the broadcast and a desired fraction of the mobile electronic devices to correctly receive the data;
- wherein the actual number of copies that must be broadcast to ensure the desired fraction of receivers correctly receive the data is calculated as:
- N≧1+|log P/log(l−R)|, where N is the number of copies transmitted, where P is the desired fraction of mobile electronic devices to correctly receive the data and R is the expected reception error rate, and wherein the likelihood of reception increases to a high level with the multiple broadcasts.
