Random access techniques for data transmission over packet-switched radio channels
Leonard Kleinrock, Fouad A. Tobagi · 1975
On the other hand, digital (pulse) systems using radio propagation are not new-e.g., telegraphy, radar, etc.Here we restrict our comments to addressed packets.The most well known example of a packet switched wire network is the ARPANET."* See References 14 and 15 for proof and for the definition of m(0, T m ), B and /. * The bandwidth is assumed to be modulated a 1 bit/Hz-sec.t This corresponds to a maximum distance of about 20 miles.The ratio of propagation delay to transmission time of a packet, denoted by a, is, in all cases less than (but very close to) or equal to 0.01.
