A fanboy is defined as “A person who loves something without question.”
Accepting things without question is counter to part of our mission to provide radio communication solutions that provide choice, performance, and best-value.
Here are some of the reasons that we don’t just accept TDMA without question:
- Interference with other devices. This is documented MANY places, including here and here.
- New accessories are required because of this interference.
- FDMA should have better coverage.
- Two-slot TDMA radio must transmit twice the transmit power to have the same energy per bit as the FDMA radio. Would you like to guess about the transmit power requirements for four-slot TDMA? Six-slot TDMA?
- Increased potential for time delay interference exists.
- Access Control is an afterthought.
- Nextel failed. Would you like to guess what technology their network was based on?
Many of the comparisons above are between TDMA and FDMA. I don’t want you to get the wrong impression; I don’t think FDMA is perfect. (As a matter of fact, recently a really smart friend predicted that CDMA will ultimately win this battle.) On the other hand, I do want to encourage you to think about things like interference, coverage, and cost before purchasing a new radio communication solution.
