Table 16: 2G operating RF frequency bands
TOBY-R2 series modules include a GMSK Power Class 4 transmitter for GSM 850 and E-GSM 900 bands, a
GMSK Power Class 1 transmitter for DCS 1800 and PCS 1900 bands, a 8-PSK Power Class E2 transmitter for all
2G bands (see Table 2), with output power and characteristics according to 3GPP TS 51.010-1 [13].
TOBY-R2 series modules 2G receiver characteristics are compliant to 3GPP TS 51.010-1 [13], with conducted
receiver sensitivity performance described in Table 17.
