Some 26 network operators have committed to deploy 3GPP LTE systems, according to latest research by GSA, the Global mobile Suppliers Association. The current status of LTE worldwide is presented in an update of the GSA Information Paper - Evolution to LTE, published yesterday. It notes up to 10 LTE networks are expected to launch commercial services in 2010.
Several operators are upgrading their networks this year with evolved HSPA (HSPA+) technology using 64 QAM modulation, enabling up to 21 Mbps downlink peak data speeds. Combining with 2x2 MIMO will mean 42Mbps as a future step when devices come to market that support these speeds.
