There is an e next to my cell phone signal. What does this mean?

There is an e icon next to my cell phone signal. What does this mean? It means you have an edge network there. This network is very fast, about 6 times faster than GPRS.

If there is both GPRS network and edge network in the local area, the edge network should be used first.

What does it mean that the cell phone signal icon shows 4GHD? Display 4HD is 4HD, mobile phone supports it, and turn on the volte function.

1.VoLTE is an IMS-based voice service. IMS supports multiple access and rich multimedia services, and has become the core network standard architecture in the all-IP era. After several years of development and maturity, IMS has now crossed the rift valley and become the mainstream choice for the transformation of VoBB and PSTN networks in the fixed voice field, and has also been determined as the standard architecture of mobile voice by 3GPP and GSMA. VoLTE is an LTE voice and an IP data transmission technology. All services are carried on the 4G network, which can realize the unification of data and voice services under the same network without 2G/3G network.

Second, in other words, 4G network not only provides high-speed data services, but also provides high-quality audio and video calls, all of which need VoLTE technology to achieve. The most direct feeling brought by VoLTE technology to 4G users is shorter connection waiting time, higher quality and more natural voice and video call effect. VoLTE is essentially different from 2G and 3G voice calls. VoLTE is an end-to-end voice solution based on all IP in 4G network.

3.VoLTE adopts high-resolution coding and decoding technology, which can improve the voice quality by about 40% compared with 2G and 3G voice calls. VoLTE brings users a lower access delay (waiting time after dialing), which is 50% lower than that of 3G, about 2 seconds, compared with 6-7 seconds in the 2G era. In addition, under 2G and 3G, dropped calls sometimes occur, but the dropped call rate of VoLTE is close to zero.

Fourthly, for operators, the deployment of VoLTE means the evolution of mobile broadband voice. In the long run, this will bring two values to operators. First, improve the utilization rate of wireless spectrum and reduce the network cost. Because for voice services, the spectrum utilization efficiency of LTE is far superior to the traditional system, reaching more than four times that of GSM.

Fifth, another value is to enhance the user experience. VoLTE experience is obviously superior to traditional CS voice. First of all, the introduction of high-definition voice and video codec has significantly improved the communication quality; Secondly, the connection time of VoLTE is greatly shortened, and the test shows that VoLTE is more than half shorter than CS call. Thirdly, seamless integration with RCS can bring rich services.

What does the e displayed next to the cell phone signal on the iphone screen mean? E stands for edge, which is the abbreviation of enhanced data rate of GSM evolution, that is, enhanced data rate GSM evolution technology. EDGE is a transitional technology from GSM to 3G, commonly known as "2G and a half (2.5G)".

This paper mainly adopts a new modulation method in GSM system, namely the most advanced multi-slot operation and 8PSK modulation technology. Because 8PSK can expand the signal space of GMSK modulation technology used in existing GSM networks from 2 to 8, each symbol contains four times as much information as the original.

The signal bar on my mobile phone. What does it mean to have a G on the screen? Indicates that GPRS Internet access is connected.

What does it mean to display an e next to the cell phone signal? E means that your mobile phone has turned on GPRS Internet access.

If there are two arrows next to e, it means that you are connecting to the network and uploading and downloading data.

Civet cats beat the plane regiment and really solve your doubts and doubts! Hope to adopt, thank you. Hehe, that's the first letter of EDGE! Last year, China Mobile upgraded its wireless network from GPRS to EDGE, and the Internet speed can be increased by more than ten times! Only when surfing the Internet in the area to be covered by the edge network and the mobile phone supports the edge network will the E signal sign be displayed! I hope my answer is helpful to you. Thank you.

There is an e next to my cell phone signal. How can I cancel this display? No, actually, e stands for EDGE, which is the network. Generally, there are two kinds: GSM and edge. Generally, the mobile phone will automatically switch, and the strong signal belongs to which side. Usually it's EDGE, which is the e you see. Don't worry, browsing Monternet and the like uses GPRS traffic. It's different. That costs money.

What does it mean to show G on the cell phone signal? China Mobile and China Unicom's 1G network display G, 2G network display E, 3G network display 3G or H+, and 4G display 4G.

The cell phone signal bar shows "H". What does this mean? This is because the mobile phone supports WCDMA R5/R6 version of HSPA, commonly known as "3.5G", which is the evolution of WCDMA R99/R4 version, including HSDPA and HSUPA. At present, the 3G network of China Unicom has fully evolved to HSDPA, and the 3G network of large and medium-sized cities has evolved to HSUPA and HSPA+. Because the mobile phone supports HSPA, and it will display "H" under the coverage of HSPA network. Due to the system and manufacturer settings, different mobile phones display differently under the HSPA network, and the displayed "3.5G", "H" and "3G+" are all indicated in the HSPA network coverage. In addition, some computers will also display "3G" under HSPA network, such as iPhone 4.

G: full name:

The theoretical peak of gprs transmission rate is 1 14Kbps, which is an earlier wireless network transmission mode.

E: full name:

EDGE has a peak transmission rate of 384kbps, which is now the mainstream wireless network transmission mode.

T or (h): full name:

TD-SCDMA technology is currently in its infancy, and the theoretical value of the current version divided into R4/R5/R6/R7R7 can reach the peak download speed 12M, but the current version is R4. Theoretical download value: 378.2KB/S, which is still relatively small, but after all, it belongs to China's independent intellectual property rights, so I still need a lot of support. When the cell phone signal is unstable, switch between these three frequency bands. Ensure the basic mobile phone call requirements.

Unicom users

G full name:

Needless to say, G is the same as mobile, but because there is no base station, Unicom's 2G network is slow.

Full name 3G or h (some mobile phones display 3.5G):

The full name of HSDPA is that its download speed can theoretically reach 7.2Mbp/s, just at the top of Unicom 3G.

H+ full name:

H+ is called HSPA+ and belongs to Unicom's 3.75G network, which shows that 3G network coverage is good at present. When H+ is displayed, the network speed is the fastest, and the theoretical speed can reach 42Mbp/s, which is the best-selling WO card of China Unicom at present, and the Unicom signal of 42Mbp. When downloading things on the mobile browser, the network coverage is good, and the peak value can reach 2.2m/s. I personally tested the screenshot, and it is stable at around 1.8m/s, which is very fast, and it is also among the three major operators at present.

Telecom users

1X full name:

1X is called CDMA 1X, which means 2G network of telecommunication. CDMA 1X refers to the first stage of cdma2000 (the rate is higher than IS-95 and lower than 2Mbps), which is basically at the same level as that of China Mobile or China Unicom, but the G of telecom 2G (namely 1X) is the most stable compared with that of other operators. Theoretically, the transmission rate of CDMA 1X mobile phone can reach 144Kb per second. Of course, in today's era of electronic products and mobile terminals, no one wants to use the 1X network.

3G full name:

3G refers to the 3G signal CDMA 2000 (EVDO. A), EV-DO is the technical name of 3G CDMA. For the sake of simplicity, it is displayed on the mobile phone as 3G, with a theoretical speed as high as 3M, and actually only about1.6m. It is based on the multiple access allocation of mobile networks and provides network traffic. These three operators have the best 3G network signals and the widest coverage. In fact, the measured download speed can reach about 290Kb/s, and the telecom card charges are theoretically cheaper.
