Radio bridge

What is a radio bridge

A radio bridge (Wireless Bridge) is two radio devices with directional antennas installed facing each other, which form a wireless communication channel between two points.

In simple terms, a radio bridge is an invisible cable made of radio waves: data flies through the air between antennas just as through a wire, connecting buildings without digging trenches.

How to choose a radio bridge

Consider the distance and line of sight (mandatory for 5/60 GHz), the required speed and the presence of interference. A pair of devices is installed symmetrically with antenna alignment. For reliability, back up the channel — for example, with a second bridge or a cable.

Where "Radio bridge" is used

A radio bridge is in demand when building and operating network and engineering infrastructure: in data centers, communication nodes, workplaces, at critical information infrastructure (CII) facilities, in banks and state corporations, as well as in the circuits of the Ministry of Internal Affairs, the FSB and other law enforcement agencies.

What to consider when choosing

When preparing a technical specification, rely on the workload profile, required interfaces and standards, operating conditions and information security requirements, including CII protection and the use of cryptographic information protection tools. Fintech JSC helps to form correct requirements and select a solution.

Supply and KTRU codes

Within state and corporate procurement, radio bridges are supplied under Federal Law 44-FZ and 223-FZ. Items are selected by KTRU codes:

• 43291400000 — Wireless communication equipment (point-to-point, point-to-multipoint radio bridges)
• 43291410000 — Antennas and auxiliary wireless network equipment

Fintech JSC provides certificates of conformity, permissions to use radio frequencies (if necessary) and warranty obligations.

Detailed description and purpose

A radio bridge is a profile solution for equipping and developing a company's infrastructure. Depending on the task, it acts as an element of the network, a computing circuit or an engineering system, and ensures stable operation of services where continuity, data protection and regulatory compliance matter. Fintech JSC selects a radio bridge configuration for the customer's specific technical specification rather than "one size fits all", so the result is a working solution rather than just a box.

Technical characteristics worth paying attention to

When forming requirements for a radio bridge, focus on the workload profile, operating conditions and industry constraints. There are no universal "best" parameters — what matters is how well they fit your infrastructure.

• Standards and protocols. Clarify the supported standards and exchange protocols — they determine compatibility with the equipment already deployed.
• Interfaces and performance. Check the set of ports and interfaces and build in a performance margin for 2–3 years of growth.
• Operating conditions. For data centers, communication nodes and industrial sites, temperature range, dust and moisture protection and power redundancy are critical.
• Information security. For CII and government sites, information security tools, FSTEC/FSB certificates and import-substitution requirements must be considered.
• Manageability and monitoring. Centralized management and logging capabilities simplify operation and audit.

Typical use cases

A radio bridge is in demand in various environments: in banks and state corporations, at critical information infrastructure (CII) facilities, in data centers and communication nodes, at employees' workplaces, and in departmental networks (Ministry of Internal Affairs, FSB and other law enforcement agencies). Each scenario has its own level of protection and redundancy.

Supply and project implementation stages

1. Audit and TOR. We study the current infrastructure, regulatory requirements and budget; we form a correct technical specification.
2. Selection and design. We propose a radio bridge configuration compatible with your environment.
3. Approval under 44-FZ / 223-FZ. We prepare documentation, a technical and commercial proposal and a budget estimate.
4. Supply. We assemble equipment with passports, certificates and protocols.
5. Installation and commissioning. Fintech JSC engineers perform installation, configuration and integration into the existing environment.
6. Training and acceptance. We train the customer's staff, hand over documentation and put the facility into operation.
7. Support. Warranty and service support, consultations on infrastructure development.

Requirements for the customer's infrastructure

Before starting the supply it is useful to prepare: a diagram of the current network or circuit, a list of compatible equipment, information security requirements (if any), and a placement and power supply plan. The more accurate the input data, the faster and more predictable the project.

Documents, certificates and regulatory compliance

Fintech JSC supplies radio bridges with a full package: passports, certificates (including FSTEC and FSB where applicable), protocols and warranty obligations. We take into account the requirements of 44-FZ and 223-FZ, import substitution and CII protection. Where needed, we select certified information security tools.

Common errors when choosing

Typical mistakes: choosing "by minimum price" without considering compatibility, ignoring information security requirements for CII, lack of performance margin and refusal of service support. They lead to rework, downtime and risks — we help to avoid them already at the TOR stage.
