Hi, Vitaliy I will surely share the final results... For now I discarded Cypress Wireless USB because of the right power = consumption and I am seriously considering Chipcon/TI CC2500 because it = works with no inductors ! You can just attach a folded dipole directly to = the part pins... The speed is great and the price is right also. It is also = available at many distributors and seems to be easy to source. it seems = mostly equivalent in functionality to nRF240L01 but would make the system = cost a little lower and sourcing small quantities seems easier.... I am also considering Microchip MiWi and chipset as a option but I have = a while to make the final decision so I will wait for the Masters conferenc= e = in August to really decide about using MiWi or not...

We may have a similar requirement in the future. -- = http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist = -- = http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
