`  == This page is poorly written, and attempts to improve it have been undone ==  I attempted to rewrite the introduction to remove vague, colloquial words like ``flaky`` and replace them with specific, well defined communication engineering terms like ``impairment`` but these edits were undone with no justification. The reference section is mixture of bullets and numbers which doesn't adhere to the style guide. Again I tried to fix this but it was undone, again for no real reason. Just because the original author saw the key word had no page, doesn't mean that that author ``owns`` the page, and it doesn't mean that the author's book has to be self-promoted by being place first reference.  This is wikipedia, not a gold mine claim on the Wild West frontier. The Johnson and Bogatin books are much more populaar (Check the ranking on Amazon for example), are more comprehensive, and have more than one chapter on the topic. What do other folks think?    `
