Quasi .. that just means virtual. Some manufacturers, in the interests of meaningless product diferentiation, choose words for effect. Looking at the article it seems that the "quasi" part is a precision offset to each base stations frequency so that a stationary mobile will not stay in a null.
All the other simulcast rules must be followed and having personally worked on a tait "quasi" system the automatic transmitter training routines are cool and fast. Hope this isnt too much hot air...

Don't know what planet this guy is from... I guess he's never had multiple brands of remote receivers through combinations of phone lines, microwave and/or radio links. > You will need high quality testing equipment to accomplish this. You mean I can't use low quality gear? shucks... There's good reason a "hot air" alarm probably went off for many of you when reading the article. cheers, skipp > While reading this article: > _http://mrtmag.com/mobile_voice/radio_big_signals_small/_ (http://mrtmag.com/mobile_voice/radio_big_signals_small/) I came > across the term "quasi-simulcast".
