Technical Requirements To Setup ISP Business

If you want to provide internet services to individuals and organizations, you must set up an Internet Service Provider (ISP) business. It is important to note that not every business can operate as an ISP. Only businesses with a prior approval from the Department of Telecommunications (DoT) are authorized to function as ISPs in India. This authorization is issued in the form of a license known as the ‘ISP license’. 

Apart from this requirement, there exist other requirements as well, including technical requirements to set up an ISP business like internet bandwidth, network operations and AAA servers among others. In this blog post, we shall discuss the major technical requirements one by one. 

List of Technical Requirements for ISP Business Setup

The technical requirements for establishing an ISP business are explained below:-

 

Internet Bandwidth

One of the most important technical requirements for an ISP business is the internet bandwidth. You must collaborate with large ISPs (tier 1 or tier 2) and purchase “wholesale” or “upstream” internet bandwidth from them. Once you purchase it, you will be able to resell it to your customers through various internet plans. 

 

Network Operations Center

Confused about what a network operations center is? It is nothing but a central, secure, climate-controlled room or data center where your main equipment is located. This hub is required to keep an eye on network activity and looks for errors in real time.

 

AAA Server

AAA server stands for Authentication, Authorization and Accounting servers. These servers are required for management of user logins, restrict access and track data usage for the purpose of billing.

 

Technology for Internet Distribution

You must decide whether you want to connect customers to the internet via cable (fibre) technology or wireless internet technology. The technical requirements will vary accordingly. 

In case of cable, you will require an optical line terminal, fiber optic cables, splitters and optical network unit. In case of wireless technology, you will require towers/antennas, base station equipment and customer premises equipment.

 

Software & Tools for Billing and Traffic Usage

An ISP business requires certain softwares and tools. To handle customer sign-ups, service packages and automatic billing, having a Billing and Customer Management System is a must. A Network Management System is also required for the purpose of monitoring network uptime, traffic usage and keeping an eye on the quality of signals.

 

Infrastructure for Power Supply and Cooling

For an ISP, having a reliable power backup is of utmost importance. In case the hub loses power, the customers would lose their internet. Therefore, to ensure uninterrupted power supply, it is necessary to have battery backups and diesel generators.

In addition to this, there needs to be an air conditioning system that can keep the server equipment cool and prevent shutdowns. 

 

Network Security and Cybersafety Measures

The ISP infrastructure must remain secure. For this, a layered defence strategy is required. This strategy includes using strong firewalls to block harmful traffic, setting strict access rules so only authorized users can get access and network segmentation to isolate critical services such as DNS, mail and databases.

The ISP should also secure their devices against cyber attacks. They must have the appropriate systems that can handle the DDoS attacks. In addition, they must regularly monitor network activity, test for weaknesses, use multi factor authentication for secure access and have a clear plan so that they can quickly respond to and report any security incidents.
