Re the above… a couple of comments on

  1. The 868MHz band for unlicensed uses exists in parts of the EU. I don’t believe it’s available in No. America.

  2. There are far less expensive ways to do this.

HI …

Tnx for the response can you give me a hint to find a good rx/tx working rs232 signal at 19200 baud duplex

what’s the physical environment - pc board vs box, power, etc.

And budget.

HI…

LAPTOP VB TERMINAL TO AVR-MT128

RS232 FROM USB PORT (TRENDNET TU-S9) 19200,8,N,1

POWER 3V , 5V ,12V (SAME POWER AS MY GSM - GPS FROM BATT)

Well for rx/tx about 50 to 200$

200m is a long path for unlicensed RF.

if your laptop has WiFi, you could buy a WiFi-to-serial network adapter. Expensive but plug and play. Available as DIY modules or as in-a-box ready to go.

modules

Lantronix WiPort - I’ve used it. works well. WiBotics.com sells a breakout board. Mouser Electronics sells WiPorts. http://wibotics.com/whb01.html sells the breakout board or both. The WiPort is about $120@1ea. With a good antenna and line of sight you can get 200m. It’s the usual WiFi story on RF. You can run the WiPot in 802.11’s ad-hoc peer-to-peer mode or have it associate to an access point to be network-accessable. For the latter, it can appear to be a virutal COM port to a PC. Or you can telnet.

Digi makes a module like WiPort

The WiPort-like modules, in a box ready to go cost $250 or more. These are available from

Lantronix, Digi, Moxa

and some lesser known ones. bb-elec.com catalog lists some.

MaxStream’s (now owned by Digi) XBee modules are just $20 and are super easy to use and have a serial port emulation mode. BUT, you’d need one on the PC side too. Their XBee-PRO-PKG is an XBeePro module in a box ready to go. Less expensive than the WiPort-like approach but not as generalized. But with XBee and all the many equivalents modules based on 802.15.4 you avoid sole-source vendors and you can expand to use ZigBee later, if you have a multi-node system in mind. In addition to MaxStream, for modules, there are 8 or so others, including Panasonic, OKI, Silicon Labs, Jennic, …
