Hong Kong Bank N7108 4G LTE and N7108D 4G LTE respectively

LTE is an abbreviation for Long Term Evolution. When the 3GPP standardization organization first formulated the LTE standard, it was positioned as an evolution and upgrade of 3G technology.

However, the development of LTE technology has far exceeded the initial expectations, and both the system architecture and transmission technology have been greatly innovated compared with the original 3G system. At present, operators around the world have generally referred to various versions of LTE as "4G".

4G is a mobile phone network independently developed by Mobile, which is much faster than 3G.

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.

One of his differences, because he may not be a special driver network, it may also be a little stronger than the camera network, but it is used in the middle of the actual network domain, and their differentiation is still in the Internet speed and a voice aspect of peacetime.

Regarding 4G, ITU has a requirement for indicators, including what uplink and downlink rate, signaling transmission delay, etc.

LTE is proposed as 3GPP in response to the emergence of WiMAX, it is still a little far from some indicators of 4G, but because of the use of OFDM, MIMO are the key technologies of the future 4G, so it is called the quasi-latest LTE-Advanced is the full meaning of 4G technology.

Differences between LTE and 4G: Different systems, different technologies, different implementation standards1, and different systems.

LTE belongs to the frequency division duplex LTE system;

4G is a time-division duplex LTE system.

2. The technology is different.

LTE uses air interface uplink and downlink transmission, and a pair of symmetrical frequency bands are used to receive and transmit data.

4G uses uplink and downlink to use the same frequency band to transmit on different time slots.

3. The implementation standards are different.

LTE is jointly developed by major enterprises and operators around the world covered by the 3GPP organization, and the two modes of FDD and TDD in the LTE standard are essentially the same, and there are only minor differences between the two modes, with a similarity of 90%.

The evolution of 4G systems is almost synchronous with the evolution of FDD systems, and the vast majority of enterprises can contribute to LTE standards in the same way as FDD and TD modes.

TD-LTE: The advanced global standard.

No, at most.

The real 4G should be LTE-Advance, at least after the 9 series standard.

Hello, TD-LTE is actually the time division duplex version of LTE, FDD-LTE is the frequency division duplex version of LTE, because of the difference in duplex mode, resulting in different frame structures on the air interface, so the air interface is incompatible with each other, but because it is also derived from the 3GPP organization, it is the same in terms of transmission, core network, etc. The 4G standard recognized by the ITU should be the subsequent evolution of LTE LTE-Advanced (including TDD and FDD duplex modes), So we say that LTE is not actually a 4G standard, we can only say that it is a standard between 3G and 4G, with some characteristics of 4G technology, but strictly speaking, it cannot be regarded as 4G, we might as well call LTE "quasi-4G" or". However, many communication companies and ** are happy to advertise LTE as 4G, perhaps this is better

Hope it helps

TD-LTE is the 4G network launched by mobile, to be precise, LTE is quasi-4G, not 4G in the real sense, LTE (Long Term Evolution) project is the evolution of 3G, LTE is not the 4G technology that people generally misunderstand, but a transition between 3G and 4G technology, and it is a global standard. TD-LTE is a mobile 3G (TD-SCDMA) launch, including TDD and FDD duplex modes. FDD (Frequency Division Duplex) is one of the two duplex modes supported by this technology, and the LTE using FDD (Frequency Division Duplex) is the time division duplex) At present, China Mobile is building TD-LTE, and China Unicom and China Telecom will build FDD-LTE 4G in the future.

925T should be supported, this is like mobile confirmation, Hong Kong also supports LTE, and it seems to cover some of the frequency bands of mobile 4G, so it can also be used theoretically! But now it's not certain! But what is certain is that the Hong Kong Bank supports the global 4G, and the mobile one is not necessarily!

925 supports international LTE, but it will not be used for a short time. By the time the day of 4G, 925 has long been eliminated by you.
