What kind of business does it say on the Internet, 4G? How much faster than 4G?

4G+ is a further evolution of 4G technology, and its academic name is LTE-A, which is the abbreviation of LTE-Advanced. 4G+ uses Carrier Aggregation (CA) technology to make 4G networks faster. Tianyi 4G+ supports a downlink peak rate of 300Mbps (theoretical rate).

The uplink peak rate is the same as the downlink network bandwidth of 100 Mbit/s to 150 Mbit/s. To put it simply, 4G+ will provide users with faster internet speeds. Tianyi 4G+ network technology:

Carrier aggregation technology is a carrier aggregation (CA) technology introduced by 3GPP in the Release 10 (TR36,913) stage, by aggregating multiple contiguous or non-contiguous carriers into a larger bandwidth (up to 100MHz). After carrier aggregation, multiple carriers provide data transmission to a terminal at the same time, which can increase the peak rate of a single terminal. China Telecom uses two-carrier aggregation technology, which can achieve the expected peak rate doubling of users.

Carrier is analogous to the "lane" of transmitting information in wireless communication, one carrier is equivalent to one lane, and carrier aggregation is to aggregate more than two carrier transmission information "lanes", so that the amount of information transmission per unit time is increased to more than two times.

4G+ is an upgraded version of the 4G network, which uses carrier aggregation technology to achieve multi-channel data transmission, which can theoretically improve the speed. Compared with the 4G network, the peak downlink speed of 4G+ can reach 300Mbps, and the uplink speed can also reach 50Mbps, which is much faster than 4G.

However, in actual use, due to various factors, it may not necessarily be much faster than 4G. For example, if there is network congestion in a certain location, or there are too many users in a certain sector, or the server of the link is congested, etc., it may affect the actual network speed.

In addition, if you want to experience the 4G+ network, in addition to the 4G+ signal coverage in the area where the mobile phone is located, you also need the mobile phone to support the 4G+ network.

The difference between 4G and 4G+ is that the actual network is different, the transmission speed is different, and the technical level is different. 1. The actual network is different: in the notification bar of the mobile phone, all the LTE is displayed, not the 4G network, so the 4G network has never been a pure bloodline 4G network, and the actual speed of the 4G network is different from the transmission speed

The peak speed of 4G downlink can reach 300Mbps, and the uplink speed can reach 50Mbps. <

Demo model:iPhone 12&&HUAWEI P40&&&Xiaomi 11 The system version file makes the actual network different:In the notification bar of the mobile phone,All that is displayed is LTE,Not 4G network,Therefore4G network has never been a pure blood4G network,The actual speed of the 4G network is,And the current 4G+ network is the justifiable 4G network。

2. Different transmission speeds: 4G+ is a new achievement achieved by applying carrier aggregation technology on the basis of the current 4G, compared with the 100Mbps data transmission speed of the 4G network, the peak speed of 4G downlink can reach 300Mbps, and the uplink speed can also reach 50Mbps.

3. Different technical levels: 4G+ belongs to a new generation of 4G network, and the speed is much faster than Telecom 4G Unicom 4G Mobile 4G. However, if you want to experience the 4G+ network, in addition to the 4G+ signal coverage in the area where the mobile phone is located, you also need the mobile phone to support the 4G+ network.

4G is a new mobile network standard, which uses new carrier aggregation technology to further improve network speed on the basis of 4G network, and integrate into our lives in a faster and more novel attitude.

4G is a new direction of network transmission, whether it is China Mobile, China Telecom, China Unicom is currently developing 4G network. Well, the speed of data transfer is much faster than the current 3G. Of course, at present, none of the three mobile companies have a real 4G network, and they are all under construction!!

4G charging is still relatively expensive, I can't afford it--
