Different types of high-speed internet servicesrouzbeh kalhor
Today, the Internet is an inseparable part of most businesses. With the advancement of technology and the expansion of the presence of businesses in cyberspace, the use of the Internet is increasing every day. Having an Internet service based on your needs is one of the most important factors in the success and improvement of your business. As a result, before buying your Internet service, it is better to know the types of Internet services so that you can choose the best service according to your needs.
Types of Internet services:
There are different ways to connect to the Internet, and each has different characteristics. The following is a summary of the types of Internet services and their differences:
DSL stands for Digital Subscriber Line. This service provides users with a high-speed connection using a telephone line (without occupying the line). Since DSL is based on telephone lines, it is the most common service for home users. This service is available and many companies in Iran provide this internet service.
DSL is more affordable than other services, but not the fastest online service on the market. The speed and quality of the DSL connection decreases as the distance between the user and the switching station increases. In other words, this service is usually used in a location close to the company providing the service. DSL Internet is available wherever there is a telephone network and provides a secure and cost-effective connection. With this service, you can use the Internet and telephone at the same time without any interference.
DSL is a fixed Internet service provided by FCP and SRVCO license holders. In the following, we will briefly introduce the types of DSL services.
ADSL or Asymmetric Digital Subscriber Line is an asymmetric DSL type. ADSL is a technology designed to provide faster connection speeds over Internet lines than older Dial-Up Internet services. Asymmetric means that the speed of uploading and downloading is different in this internet service. Because regular (home) users download more than uploading content, download speeds are usually faster than uploading.
ADSL internet speed is up to 50 MB/s depending on the bandwidth available in copper cabling. It should be noted that the speed and quality of ADSL2+ is higher than ADSL. The average ADSL2+ speed is between 1 MB/s (for upload) and 24 MB/s (for download).
VDSL is another type of DSL that stands for Very High-Speed Digital Subscriber Line. VDSL is on a cable platform, and unlike ADSL, which uses landline telephone lines, you need to use a cable to use VDSL. VDSL, like ADSL, is asymmetric and usually loads faster than loading speeds. Providers consider VDSL bandwidth as a faster and more stable connection compared to other copper-based services such as ADSL. Ideally VDSL download speed is 5 times higher than ADSL.
The SDSL service stands for Symmetric DSL, and because of its symmetry, download and upload speeds are the same. SDSL download and upload speeds are 2.3 MB per second, while VDSL download speeds are up to 52 MB and upload speeds are up to 16 MB/s.
SDSL is a type of DSL service that does not allow analog telephone service. This means that you will either not have a telephone service or will need to use a digital telephone or VoIP connection.
One way to use broadband services is to use wireless connection. As the name implies, the service does not use cables or telephone lines and uses radio frequency instead. In addition to providing much more bandwidth and stability than DSL, wireless connection significantly reduces installation costs. In the following, we will introduce different types of wireless services.
In a shared wireless Internet service, subscribers can use the frequency bandwidth in a wireless platform without the need for a telephone line or cable by installing radio equipment where there is a service provider (such as a roof). The important thing about this service is the existence of a radio on the side of the site and sending frequency to multiple subscribers (point to multipoint).
The dedicated bandwidth service is provided as a Point To Point, meaning that there is one radio on each side of the site for each customer, and the frequency is sent exclusively to one subscriber. The quality and speed of this service is guaranteed throughout the day and night. This service is suitable for organizations and businesses that need unlimited and dedicated internet to do their communication work. This service is also provided by companies with FCP and SERVCO licenses.
WiMAX stands for World Wide Interoperability for Microwave Access, which means the ability to exchange and use information globally by accessing microwaves. WiMAX provides Internet access for areas that do not have fixed cable Internet access. The most important feature of WiMAX is that it is portable and does not limit itself to a specific location. WiMAX technology provides users with a wide range of Internet access over long distances.
WiMAX works like WiFi, but at higher speeds and over longer distances for more users. WiMAX has the ability to provide services even in areas where access to wired infrastructure is difficult, as well as the ability to overcome the physical constraints of traditional wiring infrastructure. The system has two main components: a WiMAX tower and a WiMAX receiver
WiMAX, like Wi-Fi, can be connected directly to the Internet by sending a signal from a WiMAX tower via a wired connection. WiMAX transmitters can cover an approximate radius of 2 km, while the Wi-Fi range is about 30m. In other words, WiMAX turns many small scattered hotspots into a large wireless hotspot.
FTTH stands for Fiber to the Home, which uses fiber optics to access high-speed Internet. In this way, optical fiber is drawn from a central office to the subscriber’s location and allows the subscriber to use the Internet. The difference between this service and other services is that in this technology, the entire communication path is composed of high-speed optical fibers. FTTX and FCP licensed companies can provide FTTH or fiber optic service within the framework of regulatory.
TDD-LTE stands for Time Division Duplexing – Long Term Evolution. TD-LTE is a fixed wireless service provided by FWA licensed companies. The TD-LTE service requires special modems and SIM cards. The SIM card is placed in the modem and is only responsible for receiving and sending information. (It is not possible to make phone calls or send text messages.) TD-LTE does not have ADSL service restrictions, including location restrictions and the need for a telephone line.
The advantages of this service include increasing the high capacity in data transfer, reducing the cost of implementing and utilizing and allocating dynamic capacity to Uplink or Downlink streams, which improves the user experience. Using this technology, instead of dividing the frequency bandwidth, receiving and sending on a frequency bandwidth is done in different time intervals. As a result, all bandwidth capacity can be used to send or receive information, and the speed of sending and receiving information increases.
· Mobile Internet
Currently, mobile service providers offer Cellular network-based Internet access to their subscribers on the telephone line. The high speed of this service has made it possible to compare it with other internet services. Internet connection is possible without the need for a modem or complex equipment, but the disadvantages of mobile Internet include poor coverage in some parts of the country, high tariffs, weather conditions and poor support.
Mobile internet in Iran is provided using 4G, 3G and GPRS technologies. The speed of 4G technology is very high and stable, and you can easily upload or download various high-volume files. The previous generation of mobile Internet, 3G technology, has a slower speed than 4G, and its load time is relatively high. Any device that supports LTE technology can upgrade to 4G high-speed Internet by upgrading your SIM card to 4G. Some operators also support the new generation 4.5G, which allows for up to 300 MB of loading per second.
