I have been looking around for some higher powered radios and am having a hard time coming up with radios that are cabable of 115000 besides the xtend ones. I did however see some capable of 38400. Would any of the ones listed below be a good Xbee alternative? The first one is 2.4ghz though. They sell the second one with or without a case in the 900mhz and in the 433 mhz band also.
