Recently, MediaTek held a 2022 Dimensity flagship technology communication meeting, sharing the latest technological trends of mobile platforms and phased achievements in the field of communication technology, including technical themes such as 5G new dual-channel, WiFi 7, and high-precision navigation.
5G new dual-pass: 3-dimensional track leads, release full-blood experience
At the meeting, MediaTek proposed that the new dual-pass 5G is the "full-blood experience" of dual-pass, and the full-time dual-pass will become the development direction of flagship mobile phone chip technology in 2023. For many years, MediaTek has maintained its industry leadership in the field of dual-slot technology. Last year, it was the first to launch a multi-standard dual-pass technology, which can support a variety of combinations of dual 5G and 4G, making calls online at all times, and solving the long-term pain points of dual-slot users in one fell swoop. This year, MediaTek's 5G all-time dual-pass will bring a "one-step" 5G dual-pass experience to smartphones, making Dimensity dual-pass better, which can be said to be another new breakthrough in 5G technology. The technological breakthrough of
5G new dual-pass has attracted industry attention, using a single set of baseband, RF and "dynamic dual-lane" software architecture to achieve faster network rates, shorter delays and support more frequency bands, and network standard . Among them, full-time dual-pass can realize dynamic dual-lane data transmission and support more than 30 frequency band combinations. Since some frequency band combinations need to consider RF or heating, the time-sharing dual-pass can realize "downlink simultaneous + uplink time-sharing" data transmission, which can support more than 70 frequency band combinations.
Advanced 5G new dual-pass can cover more than 100 frequency bands. The network standard supports SA (SA+SA, SA+LTE, SA+NSA), NSA (NSA+LTE), and LTE (LTE+LTE), bringing rich choices.
Is the common dual-sIM dual standby on the market really useful? Once a card calls, another card will directly miss the call or disconnect the Internet. This involves that one card will occupy all the RF resources during a call, resulting in the other card having no resources available, just like we encounter a single lane situation in daily driving, which is unable to meet the two cars moving in parallel. Therefore, in order to improve the dual-scope experience, MediaTek upgrades through three dimensions, giving more usage scenarios, more frequency bands and more network standards.
After actual testing, MediaTek's new dual-communication technology, in the case of one-card calls, the network speed of another card can reach 500Mbps and the delay is only 50ms, getting rid of the problem of low speed. At the same time, the combination of specific frequency bands can also bring performance optimization. In the same frequency band of dual-slot, the dual-pass score is more than 30% faster, which can significantly improve the network speed!
With the help of the new 5G dual-pass technology, it can meet the needs of more scenarios, more frequency bands and network standards, faster network speed and lower power consumption, achieve a 3-dimensional track leading, and enable a "full blood experience" of mobile communications.
entered the 5G era, and MediaTek took the lead in launching a new Dimensity 5G mobile chip to meet the urgent demand for the popularization of 5G in the smartphone market. With its forward-looking layout and technical accumulation in 5G communication technology, we have launched many 5G mobile phone chips with outstanding product strength, such as this year's Dimensity 9000 and Dimensity 8000 series.
