Cellular network standards and generation timeline. This is a comparison of standards of wireless networking technologies for devices such as mobile phones.A new generation of cellular standards has appeared approximately every tenth year since 1G systems were introduced in 1979 and the early to mid-1980s.
CISPR is the acronym of Comité International Spécial des Perturbations Radio, [1] or the International Special Committee for Radio Protection of IEC.
