Launching your own internet service provider is an ambitious business undertaking that requires a deep understanding of network technologies and significant capital investment. WISP (Wireless Internet Service Provider) continues to grow, especially in rural areas and the private sector, where fiber optic installation is not economically feasible for large operators. Building a network from scratch is a complex engineering process, beginning with the design of radio relay lines and ending with subscriber billing setup.
Unlike cable operators, wireless providers face unique challenges: radio interference, weather dependency, and the need for careful frequency planning. However, Point-to-Multipoint The architecture allows for coverage of larger territories with lower "last mile" costs. The success of an enterprise directly depends on the quality of the selected equipment and the proper legal framework for its operations.
Before purchasing your first antenna, you need to clearly define your target audience and coverage area. Will it be a cottage community, a remote village, or temporary coverage for events? The answers to these questions will determine the choice of frequency band, whether it's the licensed 2.3 GHz band or the open-air spectrum. 5 GHzProper planning is the foundation upon which all subsequent network infrastructure is built.
Legal aspects and licensing of activities
The first and most difficult step is interacting with the communications regulator. In most countries, providing telecommunications services requires a license. You need to register a legal entity and submit documents to the national communications regulator, such as Roskomnadzor In Russia, obtaining a telecommunications license can take anywhere from several months to a year.
β οΈ Attention: Operating without a license in bands requiring permission will result in equipment confiscation and significant fines. Always check current regulatory requirements before purchasing equipment.
It's important to distinguish between frequency bands. For operation in the 2.4 GHz and 5 GHz bands (Wi-Fi standards), notification of the commencement of radio electronic equipment (REE) use is often sufficient, as long as the transmitter power does not exceed established limits. However, building long-range trunk channels often requires frequencies below 1 GHz or specific bands of 3.5β3.8 GHz, which are almost always subject to licensing and auction allocation.
In addition to a communications license, you will need to enter into contracts for rooftop leases or pole installation. Legally clear base station placement is critical. Failure to obtain a contract with the building owner may result in equipment being dismantled at the property owner's request, resulting in network downtime and loss of customers.
Technical design and selection of network topology
Network design begins with radio planning. Engineers use specialized software such as Ubiquiti Link Planner or Mimosa Planner, to calculate visibility zones and signal levels. It's necessary to take into account the Earth's curvature, the Fresnel zone, and possible obstructions such as trees or buildings. An error at the design stage will result in an unstable connection that cannot be corrected using software.
A typical provider network topology is built using the "star" or "tree" principle. At the center is the network core, connected to the upstream provider via a high-speed channel, often fiber optic. From the core, backhaul links extend to base stations scattered throughout the network. From the base stations, the signal is distributed to subscribers.
When selecting equipment for backbone networks, consider equipment that supports MIMO and TDD. Modern systems can achieve throughputs of several Gbps over distances of up to 50 km. For subscriber connections in densely populated areas, sector antennas are used to provide coverage at a specific angle, for example, 90Β° or 120Β°.
What is the Fresnel zone?
The Fresnel zone is an ellipsoid of rotation between the transmitting and receiving antennas. For stable communication, this zone must be at least 60% clear of obstacles, even if a visual object (such as a treetop) doesn't block the line of sight. Failure to observe this rule is a common cause of reduced speed in rain or fog.
Equipment required for the base station
The heart of your network will be the base station. To set up an access point in the Wi-Fi 5 or Wi-Fi 6 standard, devices from leading manufacturers such as Ubiquiti airMAX, MikroTik or CambiumA sector antenna radiates a signal in a specific direction, allowing multiple subscribers to be connected simultaneously.
To connect a single subscriber with a clear line of sight, CPE (Customer Premises Equipment) devices are used. These are directional antennas with a built-in radio module that the customer installs on the roof or facade of the building. The choice of model depends on the distance to the base station and the required speed.
Below is a comparison table of popular solutions for different deployment scenarios:
| Manufacturer | Equipment series | Frequency range | Use case scenario |
|---|---|---|---|
| Ubiquiti | airMAX ac | 5 GHz | Budget solutions for small and medium businesses |
| MikroTik | Wireless Wire / LHG | 60 GHz / 5 GHz | High-capacity highways, long-distance links |
| Cambium | ePMP | 2.4 / 5 GHz | Dense development, work in noisy air |
| TP-Link | Phantom | 5 GHz | Beginner level, short distances |
Don't forget about passive equipment. High quality lightning arrester This is essential for preserving expensive equipment. The cable must be specialized, double-insulated, and made of copper conductors, not copper-clad steel (CCA), especially for long-distance PoE power supply.
βοΈ Assembling the base station
Setting up network equipment and billing
After physical installation, comes the logical configuration phase. The key element here is the network core router, which is often based on an operating system. RouterOS or specialized Linux distributions. This is where routing protocols such as OSPF or BGP are configured if the network grows large enough.
A billing server is required to manage subscriber access and traffic pricing. Popular solutions include: Radius in conjunction with MikroTik User Manager or third-party platforms like Splynx And Wispbill, allow automatic client authorization, speed limiting according to tariff plan, and report generation. Without automation, manual payment entry and speed adjustments become impossible with 50-100 subscribers.
It's important to configure QoS (Quality of Service) correctly. This mechanism prioritizes traffic, ensuring stable voice and video calls even when the channel is fully loaded. Without proper Shape And Queue One subscriber downloading torrents can take down the entire base station.
β οΈ Attention: Default out-of-the-box hardware settings often don't provide adequate security. Be sure to change default passwords, close unnecessary ports, and set up a separate network for hardware management (Management VLAN).
Organization of the main channel (Upstream)
To distribute internet, you need to purchase it in bulk. You need to find an upstream provider willing to provide a channel in your location. Transit costs depend on the region, channel capacity, and SLA (Service Level Agreement) guarantees.
When signing a contract, pay attention to the terms of provision of a static IP address. You will need a pool of "white" IP addresses for the network to operate. Providers often allocate a separate subnet, for example, /29 or /27, which you will route within your network. Channel redundancy through a second provider or LTE modem will significantly increase the reliability of your network.
The technical implementation of the connection can be accomplished via Ethernet (twisted pair), fiber optics (SFP modules), or radio. When using fiber optics, it is necessary to agree on the connector type and data transmission standard (Gigabit Ethernet or 10G). The reliability of the upstream channel is the reliability of your entire business.
Marketing, installation and subscriber support
Launching a network is only half the battle. It's crucial to attract your first customers. Word of mouth and local advertising work well in the niche WISP segment. Offering a trial period or free installation to the first residents in the area can be a catalyst for customer growth.
Technical support must be prompt. Subscribers forgive occasional glitches, but they don't forgive ignoring problems. Availability of a hotline and remote diagnostics (via ping, traceroute (or a CPE web interface) will reduce the number of installation visits. On-site visits should be a paid service if the issue is on the client's end, to encourage users to self-service.
Scaling a business requires constant monitoring of base station utilization. When sector utilization reaches 60-70%, it's necessary to plan for the installation of an additional point or the division of the sector into narrower beams. Ignoring this rule will lead to a decline in service quality and customer churn.
What is the minimum speed required to start?
For a comfortable start in rural areas, a backbone connection of 50-100 Mbps is recommended. This will allow you to connect 20-30 active subscribers with 10-20 Mbps plans without significant speed degradation.
Does each CPE device need to be registered?
In most cases, if the base station is registered (or exempt from registration), the subscriber terminals (CPE) do not require separate registration, as they are part of the same radio-electronic system. However, legislation is subject to change, so it is advisable to consult with your local supervisory authority.
How to protect your network from hackers?
Use WPA2/WPA3 encryption, isolate client networks from each other using Private VLAN, regularly update your equipment firmware, and use complex passwords to access administrative panels.
