Say Y if you have a Metricom radio and intend to use Starmode Radio
IP. STRIP is a radio protocol developed for the MosquitoNet project
- (on the WWW at <http://mosquitonet.stanford.edu/>) to send Internet
- traffic using Metricom radios. Metricom radios are small, battery
- powered, 100kbit/sec packet radio transceivers, about the size and
- weight of a cellular telephone. (You may also have heard them called
- "Metricom modems" but we avoid the term "modem" because it misleads
- many people into thinking that you can plug a Metricom modem into a
- phone line and use it as a modem.)
