TD-LTE modems are devices that enable users to access the high-speed 4G network based on the long-term extension of time division (TD-LTE) technology. TD-LTE is a variant of LTE that uses time division duplex (TDD) to transmit and receive data in the same frequency band instead of using separate frequency bands for uplink and downlink like LTE.
This technology enables more efficient use of resources and better adaptation to asymmetric traffic needs. TD-LTE modems can support various applications such as video streaming, online gaming, cloud computing and even the Internet of Things (IoT).
One of the countries that has deployed the TD-LTE network is Iran, where the Irancell mobile phone operator has been providing TD-LTE services to its subscribers for several years. Irancell has released different models of TD-LTE modems, which we will discuss further. These modems can accept TD-LTE SIM cards and some of them can also support WiMAX network. They can connect multiple devices to the Internet at the same time through Wi-Fi or LAN ports and provide a stable and fast connection. In the future, stay with Zomit with the guide for buying TD-LTE modems and knowing the necessary tips for buying them.
The difference between ADSL and TD-LTE
TD-LTE and ADSL are two different technologies for accessing the Internet. TD-LTE stands for Time Division Long Term Evolution, while ADSL stands for Asymmetric Digital Subscriber Line. Both have their advantages and disadvantages depending on your needs and preferences. In the rest of this article, we will compare them in terms of speed, reliability, availability and related costs.
One of the main factors that affect your internet experience is its speed. The speed category refers to how fast you can download or upload data such as web pages, videos, files, etc. The higher the speed, the better the performance.
TD-LTE is a wireless technology that uses a single frequency band to transmit data in both directions, alternating between uploading and downloading over time. TD-LTE is a type of 4G technology that can reach speeds of up to 500 Mbps depending on the network conditions and the device you are using.
In contrast, ADSL is a wired technology that uses existing copper telephone lines to transmit data in both directions but at different speeds for each direction. This technology, which is one of the oldest technologies available in the field of the Internet, can achieve speeds of up to 24 Mbps for download and up to 1 Mbps for upload, depending on the distance from the source and the quality of the line.
Reliability
Another factor that affects your internet experience is its reliability. Reliability refers to the stability and stability of your connection, without any interruptions or fluctuations.
TD-LTE is a wireless technology that relies on radio signals to communicate with the nearest station. This means that it can be affected by external factors, such as weather, interference, congestion, or various obstacles. It can also have limited coverage in some areas, especially rural or remote areas.
But ADSL, whose operation is influenced by wired communication, depends on physical cables to communicate with the virtual world. This means that it can be affected by internal factors, such as fault, damage, or even destruction of lines. This technology can also have limited access in some areas, especially new or undeveloped areas.
Internet access and connection stability factors refer to the availability and convenience of your connection, with and without restrictions.
In TD-LTE connections, you only need a compatible device and a SIM card to access the Internet anywhere in the network coverage. You can also easily move your device from one place to another, as long as the signal is not lost.
But ADSL, which requires installation and wiring, you need a telephone line and a modem to access the Internet at a fixed location. You cannot easily move your device from one location to another unless you have another phone line available.
Perhaps the most important factor that makes people choose between TD-LTE and ADSL technologies is their cost. This discussion refers to how much you pay for your connection, both upfront and ongoing.
TD-LTE has a lower initial cost than ADSL. You don’t need to pay for installation or wiring and you only spend your money on the device and the SIM card. However, depending on your usage and plan, you may have a higher ongoing cost than ADSL. You may have to pay for packages or plans that vary slightly in price and credit.
On the other hand, aside from the initial costs of ADSL installation, the amount of money you pay in the long run for an Internet connection through ADSL is much less than TD-LTE connection, which of course also depends on your company and Internet provider.
Ultimately, the best choice for you depends on what you value most in your Internet connection. If you want speed and flexibility, you might prefer TD-LTE. If you want stability and affordability, you might prefer ADSL. Finally, you should also compare different plans and providers before making a decision.
What should we consider before buying TD-LTE modems?
Based on the knowledge you have gained so far about TD-LTE technology, you should know that this technology has limitations and challenges that should be considered before purchasing a TD-LTE modem. In the following, we discuss the important points that you should pay attention to when choosing a TD-LTE modem for your internet needs.
One of the first things to consider is whether the TD-LTE modem is compatible with your network operator and location. Not all network operators offer TD-LTE service and not all locations have TD-LTE coverage. You can check the availability of TD-LTE service in your area by visiting your network operator’s website or calling customer service.
In addition, you should check whether the TD-LTE modem supports the frequency band that your network operator uses for TD-LTE service. Different countries and regions may use different frequency bands for TD-LTE, such as 2300 MHz, 2600 MHz or 3500 MHz. You can also find out the frequency band of your network operator by searching online or asking customer service.
If the TD-LTE modem does not support your network operator’s frequency band, you cannot use it for TD-LTE service. Therefore, you should always make sure that the TD-LTE modem you purchase is compatible with your network operator and location.
Another important factor to consider is the performance of the TD-LTE modem. The performance of TD-LTE modems depends on various factors including chipset, antenna, operating system and software. You should look for a TD-LTE modem that has a quality chipset, powerful antenna, updated operating system and user-friendly software.
Chipset is the main component of TD-LTE modem which determines its speed, stability and performance. You should look for a TD-LTE modem that has a chipset from a reputable manufacturer such as Qualcomm, Huawei, or ZTE. The chipset should also support advanced features such as carrier aggregation, multiple output, multiple input (MIMO) and beamforming, which can increase the data rate and signal quality of the TD-LTE modem.
Antenna is another important component of TD-LTE modem that affects its data reception and transmission. You should look for a TD-LTE modem that has an external antenna or an internal antenna with high gain and diversity. The antenna should also be adjustable and rotatable so that you can optimize its position and direction according to signal strength and interference.
Firmware is the software that runs on the TD-LTE modem chipset and controls its operation. You should look for a TD-LTE modem that has an updated firmware that fixes any bugs and improves any features.
