RF gurus---A question from a wireless dullard
Ok, I need to collect and send data to/from a remote device about 500ft away. I'm looking for a single IC transceiver in a small smt package if possible. I'd like a transceiver that handles the communications with little to no control from either my laptop or the remote device i.e. either end hands 32 bits to the transceiver, something magic happens and the 32 bits appears at the other end. I really don't want to have to write code to control communications from A to B if at all possible. Moreover, I'm looking for something in an ISM band.
I've come across a couple of offerings from TI, Analog devices and Microchip that 'may' fit the bill. Any other suggestions would be greatly appreciated though.
Anywho, here's the question: If my transmitter has a power rating of 8dBm and my receiver has a receiver sensitivity of about -100dBm will I be able to TRx data back and forth across said 500ft without using an RF amp?
I'm an RF novice. I had a class once--years ago--to meet a requirement and then promptly dropped all of the knowledge in the expectation that I'd never have to fiddle with wireless comms. So, any insight into my problem would be greatly appreciated.
As always, thanks in advance for any and all support in my time of need.
[edit] The above transmits at 900'ishMHz using FSK modulation and the area between the device and my PC is fairly clear(a couple of small less than 8' tall trailers if any) if that helps.
