You are very correct st7. I should have been more specific.
I am looking at options in the realm of RF. Specifically the 2.4GHz frequency because our product is for international use. The wireless connection is point to point as opposed to mesh so ZigBee is not ideal; however, the 802.15.4 specification would be nice because of its inherent reliability and error-checking.
Transmission rate: >9600 baud
Range: 100m-500m line of sight
No standard protocol is required
No networking is required
You're not going to achieve 100-500m at 2.4Ghz very easily. I suggest that you look at 868Mhz for Europe and 915Mhz for the USA. Software stack should be 99% compatible and the hardware is very similar. 2.4Ghz is very congested with ''unfriendly'' technologies such as WIFI that have a very high duty cycle.
If you would like to contact me directly - we specialise in RF systems development and have recently launched a module based on the STM32 and CC1101 series - supports 9600 baud rate for the the serial communications.
