ZTE Corporation achieved a wireless data transmission rate of 1 Gbps in a live demonstration at Mobile Asia Expo in Shanghai.Thisrepresentsaglobal breakthrough in thedevelopment of next-generation LTE-A networks.
In the demonstration,ZTEused carrier aggregation technology with four carrier frequencies on the Fband and D band.With carrier aggregation,twoor morecarrier frequenciessharingthesameor different bandsareaggregated intoonechan?nel.This increases peak transmission speed of TD-LTE cells.ZTE used three carrier frequencies in the 2.6 Gband and one carrier in the 1.9 Gband to complete the1 Gbps demonstration.
ZTE leads the global telecommunications industry in TD-LTE 4G networks.In February,ZTE demonstrated the first F+D cross-band CA transmission,achieving speeds of 430 Mbps.In January,ZTEand China Mobile completed D-band carrier aggregation testingin atrial network in Guangzhou.An outdoor transmission speed of 223 Mbpswasachieved.
Carrier aggregation counters signal interference between neighboring cells that share the same band.By balancing the load between theprimary carrier and secondary carrier,network capacity can beincreased,and operatorscan providecus?tomers with higher network speeds and richer user experience.Carrier aggregation is helping the telecommunications in?dustry meet the challenges associated with surging data traffic and is making operator TD-LTE networks more competi?tive.
