LTE can enable peak speeds of up to 300 Mbps in the downlink for downloads, and up to 75 Mbps in the uplink for uploads. UMTS is the 3G standard for the GSM network. UMTS uses Wideband Code Division Multiple Access (W-CDMA) to increased voice capacity and provide faster speeds. The 3G GSM network does not use FDMA or TDMA technology to transmit information like 2G GSM; it uses CDMA technology. The 3G signals use 5 MHz. This is the only channel size allowed in the UMTS standard.
