At 19:00 on December 7, China Unicom According to its official microblog, it will be officially released on December 8“ Wo4G+ ”That is, the 4G+network of Unicom, its uplink/downlink speed will reach another peak, and the download speed can reach up to 38400KB/s. It is known that China Mobile and China Telecom, among the three major operators in China, have launched 4G+networks this year, but China Unicom is late, and China Unicom will finally release 4G+networks today, so far China has entered the 4G+era in an all-round way.

The biggest difference between 4G+and 4G network lies in its downlink speed, which can reach 300Mbps (38400KB/s) at most, while the maximum speed of ordinary 4G network is only 150Mbps (19200KB/s), but not all mobile phones that support 4G can support 4G+network. To give full play to the real strength of 4G+(38400KB/s), the baseband chip of its mobile phone must support LTE Cat. 5 or above (including LTE Cat. 5). Among the mobile phones on the market, Qualcomm's Snapdragon 805, Snapdragon 808 Snapdragon 810 These SoCs already support LTE Cat. 6, while chips like Snapdragon 615 and 801 only support LTE Cat. 4, Samsung External baseband of Exynos 7420 It also supports LTE Cat. 6, which is not supported by the SDK alone, even the most powerful MT6795 It only supports LTE Cat. 4.

Note: Although the Helio X20 SoC released by MediaTek in May this year has supported LTE Cat. 6 network, the chip has not been officially released so far, so no MediaTek mobile phone on the market supports LTE Cat. 6.
