The Internet has become crucial for the survival of businesses, organizations, academic institutions, and various service sectors alike. But instead of using broadband services, larger businesses and organizations are becoming increasingly dependent on the internet leased line or ILL for internet connectivity.
An internet leased line is a dedicated internet connection that provides direct connectivity on a network between multiple endpoints. Unlike broadband, it is not shared by multiple third-party users in a locality, and, thus, offers high-connectivity and a fixed bandwidth at all times.

What are the advantages of Internet Leased Lines over Broadband?

There are a number of advantages that the Internet leased line has over broadband for medium and big businesses. These advantages are discussed below:

Symmetrical Speed

A Broadband internet connection always optimizes the speed for downloads while compromising on the upload speeds whereas Internet leased lines provide symmetrical speeds for both downloads and uploads.

Maximum Speed

Broadband speeds cannot match the speed provided by a leased line connection. The latter can go up to as high as 10 Gbps, while the maximum speed of the former is much lower. According to the latest Speedtest Global Index report by Ookla, India's mean fixed broadband speed is as low as 35.98 Mbps as of March 2020.

Dedicated Connection

Broadband internet connectivity is usually shared by multiple users in a vicinity. However, an internet leased line offers a dedicated internet connection that is not shared by any other residents or businesses in a locality. This keeps the network from fluctuating during peak hours.


Internet Leased Lines are far more reliable than the broadband connection. This is because the former can easily keep a check on various performance parameters of an internet connection, be it latency or jitter.

Bandwidth range

Internet leased lines come with a much more extended range than what any business fiber broadband can provide. It starts from as low as 10 Mbps and goes higher and higher. This is a big advantage for bigger businesses or corporations where hundreds of employees are connected to the same ILL for various IT activities.

Permanent IP addresses

One of the biggest advantages of internet leased lines over broadband services for internet connectivity is that the former allows businesses and organizations to have their own permanent IP addresses on the web. Thus, having an ILL is a better option when it comes to commercial internet services.

Promised Speeds

Leased line connections offer speeds as promised. If the plan promises 1 Gbps, customers get 1 Gbps. However, broadband internet connections might fail to deliver the speeds they claim to provide.

Quality of Service (QoS)

When compared to broadband connectivity, an internet leased line provides a much better quality of service. This makes the experience of having convergent services like Voice and Video much smoother and more effective on ILL than on broadband.

Virtual Private Network

Employees of a corporation or organization spread across several branches can have their very own virtual private network on an internet leased line. A virtual private network on an ILL is much more effective than the one on a broadband connection.

Connections to multiple sites

While broadband internet connections usually connect one single site to the ISP's network, leased lines have the option to connect multiple sites together to create a wide area network. This is useful for businesses that have multiple branches on different sites.

Low Latency and Jitter

Compared to broadband internet, leased lines have way fewer delays in data transmission (latency) as well as fewer variations in these delays (jitter). This makes activities like video conferencing smoother over leased lines.


An internet leased line is far more secure than broadband internet connectivity. Because of the absence of any third-party users, an ILL naturally becomes much more secure from any exploitation and malicious cyberattacks.

Diverse Physical Routes

In the case of broadband services, customers do not have a choice over the route of the connection. However, customers can choose to have diverse physical routes for the leased line connections that act as backup.


An internet leased line comes with unlimited usage plans which let businesses avail of services like video conferencing and surveillance, voice over IP and etc. with the same plan. In the case of broadband internet, the costs would keep on increasing with added services and bandwidth use.
