subject: Simple wireless RF IC solutions with sub-GHz radio [print this page] Range, low interference and low power consumption are basic advantages of sub-GHz transceiver applications over 2.4GHz apps. One of the disadvantages often cited is that the antennas are larger than those used in 2.4GHz networks. The optimal antenna size for 433MHz applications, for instance, can be up to seven inches. However, antenna size and frequency are inversely proportional. If node size is an important design consideration, developers can raise the frequency (up to 950MHz) in order to employ a smaller antenna.
