[RCSE] Breaking the 40 Spektrum Radio Barrier

2008-03-24 Thread aeajr
Spektrum RC splits the 2.4 GHz band into 80 slices. When you turn on a Spektrum transmitter it takes two of these slices at its channels for talking to the receiver. It has long been expected that if you tried to turn on the 41st Spektrum system, it would not be able to lock with the receiver.

This is likely to start an IT geeky discussion but its worth mentioning. This brings up my very first concern on this band. My concern was that there are literally hundreds of gain boosting products on the market for 2.4 Wimax technology. Many of these devices such as home routers and small to

Thank the wireless network guys for pushing for a ban on 2.4 for models. Burn your Cisco routers. Bill Bunny Kuhlman wrote: While 2.4 GHz virtually eliminates interference issues, it should be noted that using this frequency in nations other than the U.S. may be increasingly

WiMAX uses frequencies between 2 and 11GHz but as the 2.4 and 5.2 bands are unlicensed they're likely to get used for testing. Since spectrum is now something you buy, sell and hoard just like any other commodity its likely that everyone will be squeezing into what unlicensed space there is to

using the same two frequencies, they will each only be using a small part of the available bandwidth. end quote - Original Message - From: Ed Anderson [EMAIL PROTECTED] To: Soaring@airage.com Sent: Friday, March 21, 2008 1:21 PM Subject: [RCSE] Breaking the 40 Spektrum Radio Barrier

Its the same as a wireless network. In this network all the stations transmit short packets of data only when they need to. The actual bandwidth (amount of data) needed to control a model plane is very small compared to the amount you could get on one of those channels if it was running full
