  • 1. LTE Advanced Additional Materials
  • 2. LTE-Advanced Spectrum Bands Possible Future Spectrum Band Usage (According to WRC’07) LTE-Advanced specifications has introduced the following other ITU-R IMT bands that are not precluded in the future: • Possible frequency bands in 450 MHz – 470 MHz band • Possible frequency bands in 698 MHz – 862 MHz band • Possible frequency bands in 790 MHz – 862 MHz band • Possible frequency bands in 2.3 GHz – 2.4 GHz band • Possible frequency bands in 3.4 GHz – 3.8 GHz band • Possible frequency bands in 3.4 GHz – 3.6 GHz as well as 3.6 GHz – 4.2 GHz • Possible frequency bands in 4.4 GHz – 4.99 GHz bandCopyright by IS-Wireless.
