"No matter how far we come with technology, it seems that the pain of intermittent connectivity will always plague us. Even in major cities like New York, you'd be hard pressed not\u00A0to lose cell reception at random, yet highly inconvenient times as you travel across town.\r\n\r\nWith this in mind, MIT Developers may have solved some of our data woes with a new\u00A0method\u00A0of utilizing\u00A0error correcting codes.\r\n\r\nDevelopers at MIT have announced a new technique of encoding information &amp;quot;so that it can be transmitted across a communication channel \u2014 such as an optical fiber or a wireless connection \u2014 with perfect fidelity, even in the presence of the corrupting influences known as noise.&amp;quot;\r\n\r\nAccording to Gregory Wornell, a professor in the Department of Electrical Engineering and Computer Science at MIT, the\u00A0breakthrough\u00A0is that the system never repeats transmissions. &amp;quot;We send the first part of the codeword. If it doesn\u2019t succeed, we send the second part, and so on...We always send the next part rather than resending the same part again.&amp;quot;\r\n\r\nWornell continues, explaining that if you &amp;quot;marry the first part, which was too noisy to decode, with the second and any subsequent parts, they together constitute a new, good encoding of the message for a higher level of noise.\u201D\r\n\r\nMore details from the MIT News Office:\r\nAn encoded message is called a codeword; the noisier the channel, the longer the codeword has to be to ensure perfect communication. But the longer the codeword, the longer it takes to transmit the message. So the ideal of maximally efficient, perfectly faithful communication requires precisely matching codeword length to the level of noise in the channel.\r\n\r\n...As anyone who\u2019s used a cellphone knows, reception quality can vary at locations just a few feet apart \u2014 or even at a single location. Noise measurements can rapidly become outdated, and wireless devices routinely end up using codewords that are too long, squandering bandwidth, or too short, making accurate decoding impossible.\r\nAs far as how long it will take for us to see this sort of breakthrough impact the cellular industry,\u00A0H. Vincent Poor, the dean of the School of Engineering and Applied Science at Princeton University, believes that the method developed by\u00A0Wornell and his colleagues is highly practical and sees little reason for it to not be embraced quickly by providers."^^<http://www.w3.org/2001/XMLSchema#string>
