Several standards has been defined for wireless. Their specifications look well on paper but there are a lot of problems to apply them in practice. Due to attempts for maximal complexity and performance these protocols are complicated, require high-tech hardware and application development is difficult, lengthy and expensive. Complex protocols also imply bloated communications and lowered data rates. This gap must be closed by high output RF power which results in higher noise, increased traffic and high power consumption… It leads to situation where despite of high costs it is hardly possible to achieve reasonable results even for much simpler applications than ones these standards has been designed for.
In 2004 an RF platform was established based on different views:
