Edholm's law, proposed by and named after Phil Edholm, refers to the observation that the three categories of telecommunication,[1] namely wireless (mobile), nomadic (wireless without mobility) and wired networks (fixed), are in lockstep and gradually converging.[2] Edholm's law also holds that data rates for these telecommunications categories increase on similar exponential curves, with the slower rates trailing the faster ones by a predictable time lag.[3] Edholm's law predicts that the bandwidth and data rates double every 18 months, which has proven to be true since the 1970s.[1][4] The trend is evident in the cases of Internet,[1] cellular (mobile), wireless LAN and wireless personal area networks.[4]
