How to Choose The Best 4G WIFI Module Uart?

PublishTime： 2022-02-15 Article Source：SKYLAB

With a current 4G WIFI module uart product, the number of devices that allow connection usually ranges from 5 to 10 devices, a few have a larger number.If you use it for personal purposes, this criterion is not very important, you can ignore it. But if you use it for work, choose a product that allows connecting at least 10 devices at the same time.This article SKYLAB will share why do you need module uart and how to choose the best 4G WIFI module uart?

1. Why do you need module uart?

Some 4G WIFI modules allow users to use as a backup battery. With this 2-in-1 feature, you save quite a bit of money on purchasing backup batteries and storage space.

However, this means that the battery capacity of the device will decrease rapidly, directly affecting the module uart, if you use it for purposes such as a power bank. Separate management software is also one of the other preeminent features that I want to mention here. You can control the device on your phone or tablet without touching the product.

At the same time, the display screen always has detailed parameters of usage time, transmission speed, remaining capacity, number of connected devices ... and also detect other WIFI networks.

Good product design with low price

With any product, the price is always proportional to the quality and features that the product brings to the user.

High price corresponds to quality, good product design like module uart and low price, vice versa. Can't expect cheap products with the same quality as brand names, this is completely ridiculous.

Therefore, before preparing a budget, please refer to information about product features and prices on many different websites to evaluate and choose the right product for your needs and requirements. in the most affordable price segment.

According to user reviews, 4G WIFI modules priced from 500 to 1500K are the most popular products today.

Brand and product quality of module uart

After price, brand is one of the other important factors that determine product quality. Module uart from reputable brands always have a certain reliability for consumers.

In addition, genuine devices from famous brands will have more accurate parameters. Leads to stronger WIFI broadcasting, longer battery life.

The product warranty period

Depending on the brand, the product warranty period of the 4G WIFI router is not the same, most of them are from 1-2 years. Some quality products have a warranty period of up to 3-4 years, but there are also some product lines with only 6 months warranty.

The product's warranty period is also one of the bases for evaluating product quality that you can't ignore. You will feel more secure when owning a product with a long warranty policy, right?

2. How to choose the best 4G WIFI module uart?

With many types of 4G WIFI modules available in the market, it is important to choose a WIFI router from a well-known brand. The manufacturer's track record will tell you if the product is well made and complies with promotional claims.

However, to ensure that a 4G WIFI module meets the needs of the most demanding users, you should check the following features.

Downloading & Uploading Speed

4G WIFI modules have different file upload and download speeds. Based on this criterion, there are about two dozen types of LTE. With the most common types being CAT4, CAT6 and CAT11. The module uart can provide download speeds of up to 600Mbps and upload speeds of 50Mbps.

The best 4G WIFI module today picture 11 If you are looking for the fastest possible WIFI module choose ESP8266 wifi module. This transmitter uses Category-19 LTE Advanced Pro chipset. Note that in most cases, the speeds indicated in the product description are theoretical. Which means they are often slower in practice.

WIFI Standard for all devices

Today 's best 4G WIFI modules usually support 802.11ac or 802.11ax WIFI standards. Both are backward compatible and can work with older devices. But of course, at the cost of speed. Currently, most 4G WIFI modules support 802.11n and only run on the 2.4GHz spectrum. However, module uart is a higher speed models that use both the 2.4GHz and 5GHz bands.

If you need a high throughput because many devices are requiring an Internet connection – laptops, smartphones, smart TVs, game consoles, cameras, etc. – then the 802.11ax standard should be the choice. Choose the best for you.

It can simultaneously deliver several gigabits per second to multiple devices on a single channel. This standard offers a significant increase in performance.

LAN port for Ethernet cables

The best 4G WIFI module today picture 124G WIFI modules usually have at least one or four wired network ports for connecting Ethernet cables. Cheaper options tend to have only“Fast Ethernet”features that allow for transmissions of no more than 100 megabits per second. The choice depends on the purpose of using your WIFI module uart.

For just accessing the Internet, this may be enough. However, if you plan to transfer files across different devices, you will need to invest in a 4G router with Gigabit ports.

Limitations of WIFI range extenders

WIFI range extenders are extremely useful devices. It can instantly increase the coverage of a weak WIFI network. At the same time, the amplifier also eliminates weak signal areas. However, they have certain limitations.

Separate network: WIFI extender creates a separate network. That means your devices have to go from the main network to the extended network as you move around the house. Some module uart can switch between WIFI networks relatively well.

While others take longer

Adding an extra WIFI network will also create signal interference problems. Especially in the 2.4 GHz band which only offers three non-overlapping channels.

Limited bandwidth

Due to the way WIFI extenders work. They effectively reduce the available bandwidth by 1/2 to the devices connected to them. If network performance is extremely important to you, you should research other solutions. Such as the network.

We hope the list will help you choose the best 4G WIFI module uart today. Remember, there is no such thing as a“perfect”ingredient.

3. Summary module uart

The wireless 4G WIFI module market is saturated, and finding a good 4G WIFI module is not an easy thing. That's when lists like this come into play. This list of the top 8 4G WIFI routers takes note of things like customer needs. Also advise on an appropriate budget to spend on a 4G WIFI module.
