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.
The standard encoding for GSM messages is the 7-bit default alphabet as defined in the 23.038 recommendation. Seven-bit characters must be encoded into octets following one of three packing modes: CBS: using this encoding, it is possible to send up to 93 characters (packed in up to 82 octets) in one SMS message in a Cell Broadcast Service.

Using this method, long messages are split into smaller messages by ...
IS-41, also known as ANSI-41, [1] is a mobile, cellular telecommunications system standard to support mobility management by enabling the networking of switches. ANSI-41 is the standard now approved for use as the network-side companion to the wireless-side AMPS (analog), IS-136 ( Digital AMPS ), cdmaOne , and CDMA2000 networks.
