What is 3G in a tablet

A contemporary individual cannot function without Internet access. A myriad of services and facilities have made the transition to the World Wide Web, ranging from banking to food delivery and entertainment. Even interpersonal communication is now predominantly conducted online. However, reliable cable or wireless Wi-Fi networks are not always readily available. So what should one do if they only have a trusty tablet device in their possession and there is no accessible Wi-Fi hotspot nearby?

In such a scenario, some devices are equipped with 3G technology. For instance, all smartphones support this technology as it offers not only Internet connectivity, but also enables voice communication. Unfortunately, the same cannot be said for tablets.

What is 3G technology in a tablet

As previously stated, all cellphones are inherently equipped with third-generation communication technology. Without it, their functionality would be compromised. However, other portable devices are typically not purchased specifically for communication purposes and may not always possess the essential features.

Take tablets, for instance, which offer two alternatives for mobile network support:

1. Internal. Certain devices come with an internal module that enables them to work with mobile communication. By purchasing a SIM card and installing the necessary programs, you can easily use the internet or make calls on these devices, just like on a phone.
2. External. However, even devices without an internal module can still receive a signal. In order to do so, an external modem is necessary, which resembles a regular flash drive. These modems usually utilize USB connectors, making connection issues rare, especially considering the availability of adapters.

Once connected, everything functions like a standard mobile connection. Its operation is based on the transmission of information in packets using radio waves. However, this technology is diverse and consists of various families.

Varieties of 3G standard

The IMT-2000 standards, which represent the third generation of mobile communication technologies, consist of five different standards:

1. The first standard, TD-CDMA/TD-SCDMA, was developed in China.
2. The second standard is DECT.
3. The third standard, also known as W-CDMA, is UMTS.
4. The fourth standard is UWC-136.
5. The fifth standard is CDMA2000, also referred to as IMT-MC.

Out of these five standards, UMTS and CDMA2000 are the most widely used. Both of these standards are based on CDMA technology, which stands for Code Division Multiple Access. In CDMA, transmission channels share a common frequency band but use different coding sequences.

What 3G technology is needed for

As evident from the full name of the technology ("3rd Generation" or "third generation"), it was not the first of its kind. Earlier, mobile communication was facilitated through 2G. The second generation primarily operated on the GSM standard. During that time, communication was comparatively less efficient, powerful, and speedy.

However, as technology progressed, people developed more requirements. With time, cell phones and the internet became common, and the old technologies were no longer capable of fulfilling their tasks. 2.5G came first, followed by 2.75G, and eventually 3G emerged. The third generation surpassed its predecessors in every aspect, delivering high data transfer rates, satisfactory sound quality, and extensive coverage.

Despite the emergence of 4G, the previous generation remains relevant. The old format is still used by billions of individuals, and it is premature to discuss the widespread availability of the new mobile internet. This is why the demand for 3G for mobile communication and internet access still exists. Without Wi-Fi, it is difficult to stray far from one’s personal computer, and many individuals require network connectivity even for work purposes.

Important! New standards are gradually becoming integrated into our daily lives. Some telecommunications operators have already begun discontinuing services associated with 3G and replacing them with 4G. It is essential to closely monitor these developments and change SIM cards to support the new standards in a timely manner.

Setting up 3G on your tablet

If you have recently purchased a new tablet and have also acquired a separate SIM card and modem, if necessary, you may be wondering what your next steps should be. One important task is to install the necessary programs and find a way to connect to the internet so you can start browsing the World Wide Web. Fortunately, the setup process is quite straightforward:

1. To start, connect your tablet to a modem or insert a SIM card.
2. Access the system settings.
3. In the "Wireless networks" section, click on "More…" to see all options and locate the "Mobile communication" item.
4. In the "3G Service" tab, set the operating mode to "3G".
5. Proceed to the "Access Points" tab and verify if there is a suitable one. It should be configured automatically, but you can always contact your service provider for assistance with manual setup.
6. Add the desired hotspot and enable "Data Transfer" in the settings.
