What is 4G technology?

4G technology not only provides faster data transfer speeds but also supports more device connections. The opposite is LTE (Long-Term Evolution) technology, which is one of the four core technologies in the Long-Term Evolution plan.

What is LTE?

LTE (Long Term Evolution) is a long-term evolution of the UMTS (Universal Mobile Telecommunications System) technology standard developed by the 3GPP (The 3rd Generation Partnership Project).

The LTE system introduces OFDM (Orthogonal Frequency Division Multiplexing) and MIMO (Multi-Input & Multi-Output) technology.

Output, Multi-Input & Multi-Output, and other key technologies, significantly increase the spectral efficiency and data transmission rate (20M bandwidth 2X2MIMO in the case of 64QAM, theoretical downlink maximum transmission rate of 201Mbps, after removing the signaling overhead is about 150Mbps.

But according to the actual network and terminal capacity limitations, generally considered the peak downlink rate of (100Mbps, 50Mbps for uplink), and supports multiple bandwidth allocations: 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz, and 20MHz, etc.,

And supports the global mainstream 2G/3G bands and some new bands, so the spectrum allocation is more flexible, and the system capacity and coverage are significantly improved.

The difference between 4G and LTE

4G is the fourth generation of mobile communication and its technology (The 4th Generation Communication System) for short. In the definition of ITU (International Telecommunication Union), any wireless data network system that reaches or exceeds 100Mbps can be called 4G.

4G technology is a broadband wireless access method based on IP protocol, which is characterized by high data transmission rate, low latency, wide coverage, high capacity, and high security.

LTE is a wireless communication technology based on OFDM (Orthogonal Frequency Division Multiplexing) modulation.
LTE technology is based on the 3GPP standard development, LTE at the beginning is the 3G “enhanced version”, technically known as 3.9G, with the later development of LTE gradually close to the real 4G.

It can be seen that 4G and LTE are not the same thing, LTE network can meet the standards of a 4G network (downstream 100Mbps), and the 4G era is dominated by LTE networks, so the two are usually combined, collectively referred to as 4G LTE.

Like 4G, LTE is designed to provide high-speed data transmission.LTE introduces MIMO (Multiple Input Multiple Output) antenna technology, which allows data to be sent to multiple users at the same time, thereby increasing network capacity and throughput.

In addition, LTE supports a wide range of network deployment scenarios, including macrocells, microcells, and hotspots.LTE technology also enables low-latency and highly reliable communication services, making the experience of using smartphones, tablets, and other mobile devices smoother.

Although what we now call 4G is usually LTE, they differ in many ways. For example, compared to 4G LTE is still slightly inferior in terms of data transfer speeds, and 4G can support the connection of more devices, while LTE can only support a certain number of end devices.

In addition, 4G can provide better network quality and service experience, such as higher peak rate, lower latency, etc., while LTE needs to be adjusted according to different network environments and user needs.

Both 4G and LTE use packet-switching technology for data transmission. In 4G, data is divided into small packets and distributed to different users using different frequencies;

In LTE, these packets are further divided into smaller sub-frames to make better use of spectrum resources. 4G and LTE technologies can both use two different network standards, TD-LTE and FDD-LTE.

How to choose a 4G LTE antenna?

The 4G antenna LTEantenna selection is still based on the actual needs of the product.

The main parameters of antenna selection are frequency band, size, gain, standing wave ratio, polarization, etc.

The standing wave ratio is of course the smaller the better, and now the antenna can basically achieve within 2.0:1.

The larger the gain, the better, but the gain of different antenna structures is different. Usually, the external antenna gain is the best but the designed antenna also has a better gain.
