The Technical Research Of Sar Test For Mobile Station

With the rapid development of mobile communication technology, mobile stations (MS), which initially were luxury items, have migrated to become high-volume mass-market goods. The demands for handset market are keeping improvement, mobile station R&D and manufacturing industry are also flourish into the sky, new features, new functions, new design phones are launching without endless, meanwhile mobile station replacement is strong accelerating. Today the traditional feature mobile stations are replaced by Smart phones, whose OS are including Android, Apple OS, Symbian, Windows Mobile, Linux, are very popular in the last couple of years and there OS market shares are growing. The earliest1G which is analog mobile stations has been phased out the market for a long time, the2G which includes GSM and CDMA mobile stations have been widely used worldwide, the3G which includes TD-SCDMA, WCDMA, CDMA2000mobile stations have taken off globally, and today the4G, which refers to LTE technology, also has been launched by international operators.With the rapid increasing of huge new type mobile stations, people are getting more RF radioation which from these new high technology products in their normal life. People have payed more attention to focus that whether the radioation of these mobile stations would make any nagetive effection about people’s heath. The SAR test as an important solution was certificated by many countries that evaluate how much the RF radioation from mobile station could be absorded by human’s body in different conditions, that is constantly improved and developed with the development of many kinds of the new telecommunication technology products in order to match the testing of different sorts of mobile stations.This paper introduces the requirement and evaluation procedures about SAR test form FCC and some motheds of SAR test for some classic telecommunication products in the market, such as: SAR evaluation procedure and standards for2G,3G mobile stations; SAR evaluation requirements and standards about for radio communication modules in portable computers, and so on.
