h refers to the network signal between the 3G network and the 4G network. H is an upgraded version of hsdpa, hspa, which is an upgraded version of the 3G network. It belongs to the 3.75G network in terms of network division, and its speed can reach 21M-42M; the normal Internet speed of users using Internet equipment is generally 250k/s. Nowadays, most areas are covered by 4G networks, so in most cases the mobile phone displays the 4G network logo; but when the surrounding 4G network is not strong enough, the mobile phone will automatically switch the signal to the H network with poorer network speed. The network speed will be reduced a lot.
#The operating environment of this tutorial: MIUI 13 system, Xiaomi 12 mobile phone.
When the H+ sign is displayed in the mobile phone signal bar, it means that the network environment where the mobile phone is located is between the 3G network and the 4G network.
H is an upgraded version of hsdpa hspa, is 3.75G, the speed can reach 21M-42M. The speeds are all theoretical speeds. There are many factors that actually affect it, so it generally won't be stable at the maximum speed.
H, this logo is actually an upgraded version of the 3G network, the full name is HSPA. In terms of network division, it belongs to a 3.75G network, and its downlink speed can reach up to 42Mb/s. The normal Internet speed of users' Internet equipment is generally 250k/s. According to calculations, theoretically H network speed should be much faster than 3G network speed.
Currently, most areas are covered by 4G networks, so in most cases the mobile phone displays the 4G network logo. However, when the surrounding 4G network is not strong enough, the mobile phone will automatically switch the signal to the H network with poorer network speed. At this time, the network speed will be reduced a lot.

Other network signal identifiers on the mobile phone:
Signal identification: G. The full English name of G is GPRS, which belongs to the 2.5G network. It is a mobile data service available to GSM mobile phone users and is also the earliest wireless network transmission method.
Signal identification: T. This signal is relatively rare and represents the TD-SCDMA network format, which is China Mobile's 3G network. It is the third generation mobile communication standard proposed by China and one of the three 3G standards approved by the ITU.
Signal identification: 4G. This is the signal logo displayed by most mobile phones currently. 4G is the abbreviation of the fourth generation of mobile communication technology. The theoretical transmission rate can reach up to 100Mbps.
The signals in mobile phones are G, E, O, 3G, H, and H. They all mean network signals, but these letters represent different networks:
1. G refers to GPRS, which is a mobile data service available to GSM mobile phone users. GPRS can be said to be the continuation of GSM and is a 2.5G network. O is displayed on the iPhone;
2. E refers to EDGE network, which is an enhanced data rate GSM evolution technology and belongs to 2.75G;
3. 3G refers to ordinary 3G network, which is common in China There are three types of 3G: China Telecom's CDMA2000, China Unicom's WCDMA and China Mobile's TD-SCDMA, with speeds between 2-7M; 3.5G, the speed can reach 14.4M;
5. H is common on China Unicom’s WCDMA mobile phones. The upgraded version of hsdpa, HSPA, is 3.75G, the speed can reach 21M-42M;
The sequence from slow to fast is G
