RF refers to radio frequency, the mode of communicating for wireless technologies of all kinds, including cordless phones, radar, ham radio, GPS, and radio and television broadcasts. RF technology is so much a portion of our lives we scarcely detect it for it is ubiquity. From baby monitors to cell phones, Bluetooth® to remote control toys, RF waves are all around us. RF waves are electromagnetic waves which propagate at the speed of light, or 186,000 miles per second (300,000 km/s). The frequencies of RF waves, however, are slower than those of visible light, making RF waves invisible to the humane eye.
The wireless energy saving monitor and control scheme as well as the tire-pressure monitoring scheme (TPMS) and some other apps adopt the high performance/price ratio RF transceiver modules, making the productions very competitory in the market, likewise making people’s working and living more comfortable and conveniently.
Universal ISM Band FSK Transceiver Module is a compact and low cost FSK wireless transceiver module based on ISM band. Its core circuit adopts RF transceiver chips of the distinctive PLL technology.

By Jennifer Ray A year ago, I purchased the Logitech Harmony 880 Advanced Universal Remote Control and have liked it so much that I had determined to buy a second remote this year in order to have one upstairs and one downstairs. Although both the Harmony 880 and the new Harmony One each control a good deal of appliances (I presently have 14 appliances set up on each), it became tiresome to have to go to a dissimilar floor of the house to grab the remote for the other level. Then Amazon Vine received the Harmony One remote from Logitech for review, and I was thrilled to be capable to review it.
