Samsung, Qualcomm group as much as produce 20% quicker 5G downlink information speeds

Samsung and Qualcomm announced late last week that they’ve elevated 5G downlink pace by 20% by finishing assessments for 1024 Quadrature Amplitude Modulation (QAM) for each Frequency Division Duplex (FDD) and Time Division Duplex (TDD) spectrum bands. The previous makes use of two completely different frequencies for transmitting and receiving whereas TDD makes use of a single frequency and separates transmitting and receiving by time.

QAM is a complicated modulation know-how that pertains to the quantity of information (in bits) that may be despatched over every transmission. The upper the QAM quantity, the extra environment friendly a transmission is. Whereas most business networks use 256QAM, 3GPP Launch 17 requires the usage of 1024QAM. As Samsung notes, “This enhanced QAM know-how helps operators maximize their use of spectrum sources and permits cellular customers to seamlessly get pleasure from varied cellular companies comparable to reside video streaming and on-line multi-player gaming, which require increased obtain speeds.”

The check came about at Sammy’s R&D lab in Korea utilizing Samsung’s 5G vRAN software program and radios supporting 2.1GHz (FDD) and three.5GHz (TDD) bands. Qualcomm’s contribution included its telephone kind issue machine which is provided with the chip designer’s newest Snapdragon X75 5G Modem. That is the modem presently used on the Samsung Galaxy S24 sequence and also needs to be used on the upcoming iPhone 16 line later this 12 months.
Samsung and Qualcomm have been capable of ship a downlink information pace of 485Mbps, 20% quicker than the pace achieved utilizing 256QAM. Whereas this pace was achieved with a 20MHz bandwidth, utilizing Provider Aggregation, increased throughput could be created. Final 12 months, Samsung and Qualcomm have been the primary to realize a simultaneous 5G 2x uplink and 4x downlink provider aggregation for FDD spectrum. Provider Aggregation will increase information switch charges and ends in quicker downlink and uplink speeds. 

To know Provider Aggregation, take into consideration how briskly visitors strikes on a one-lane freeway. Including a second lane permits the freeway to accommodate extra visitors that may then transfer quicker.

Sunil Patil, Vice President, Product Administration, Qualcomm Applied sciences, Inc. says, “We’re honored to have collaborated with Samsung on this trade first achievement. This accomplishment showcases our unwavering dedication to supporting operators of their efforts to boost 5G throughput and enhance spectral effectivity. By leveraging superior QAM know-how, we’re empowering operators to maximise spectrum sources and ship seamless, high-speed cellular companies to 5G customers.”
