  • Page 4: General Descriptions

    SECTION 2 GENERAL DESCRIPTIONS 2.1 Multi-band : CMD-J6/J26 support E-GSM 900 and DCS 1800 multi-band functionality. For the use in Europe and in other countries worldwide, ETSI has specified GSM standards into two frequency bands. That is the 900-MHz and 1800-MHz band and is usually referred to as GSM900 and GSM1800 (formerly DCS1800).
  • Page 5: Radio Frequency Power Level ………………………………

    2.2 Radio Frequency Power Levels: Between the DCS 1800 and both GSM Systems are differences regarding the power level. DCS 1800 basically needs lower power levels. If the performance of a MS for GSM system was certified of 2W (Power Class 4), then in the DCS-1800 system it is only 1W (Power Class 1).
