The difference between VDSL and ADSL modems:
Up to this point, you have probably realized some of the differences between VDSL and ADSL modems, but in this section, we want to fully examine the differences between these modems.
Bandwidth: The most obvious difference between these two technologies is their download and upload bandwidth, the download speed of VDSL technology is more than 6 times that of ADSL. Of course, if we consider the newer VDSL2 and VDSL2+ technologies, this difference is much greater.
Cost: It goes without saying that the cost of the internet and also setting up the VDSL service is a little more than ADSL. The cost of infrastructure, higher speed, less number of users and higher price of modems determine this price difference.
Internet providers: Few ISP companies currently offer VDSL service, and the use of this technology is extremely limited (unlike ADSL), which is used in many homes.
Available distance: The signal strength in VDSL technology drops sharply with increasing distance, so the ISP can provide users with the maximum speed of this service for a short distance. Whereas, this distance is much longer for ADSL. As you can see in the graph below, VDSL internet speed is much higher than ADSL at short distances, but as the distance increases, their speeds gradually become equal, but ADSL Internet speed does not change much with increasing distance.
With the spread of Internet services and the increasing quality of online content (video, music, etc.), the need for more Internet bandwidth is felt more and more, and users will seek to use faster connection methods. Internet businesses have the greatest need for more bandwidth and it is essential that the infrastructure of new technologies such as VDSL2, VDSL and TD-LTE be developed as soon as possible. Despite the many advantages of VDSL, it can be considered a suitable option – at least in big cities – to improve the bandwidth of users.
How to set up VDSL Internet:
What companies offer VDSL internet?
Currently, shuttle and telecommunication companies have started registering VDSL internet for Tehran and Qom cities. Of course, this type of internet has been provided for long time ago for administrative, commercial and residential complexes that had the necessary infrastructure. Among the companies that provide enterprise VDSL, we can mention Shuttle, Datak and Pishgaman.
Do we need a special modem to set up VDSL internet?
To use VDSL services, you need a modem that supports VDSL technology. Some ADSL modems also support VDSL but only in expensive modems! So in most cases you will need a new modem. The telecommunications company has offered two types of modems with cash prices of 350 and 550 thousand tomans, which you can also buy in installments. No information about the technical specifications of these VDSL modems has been published. Shuttle company has not released any information about VDSL modems.
You can also buy VDSL modems through online and physical stores. Manufacturers such as D-Link, TP-Link, Asus and Tenda offer their VDSL modems in different models. You can buy your desired VDSL modem from the Netrun online store.
Is the VDSL internet tariff higher than ADSL?
The telecommunication company has announced the tariff for VDSL internet, and by examining these tariffs, we can see that the cost of VDSL internet is similar to ADSL internet and is no different from before. However, the shuttle company has not released any information in this regard so far. It seems that the Ministry of Communications will establish rules that the price of this type of internet will not be different from the previous generation.
