Wi-Fi access point

Wi-Fi access point: what it is in simple words

A Wi-Fi access point (AP) is a network device that provides wireless connection of client devices (laptops, phones, IoT) to a corporate or home network. Coverage, speed and security of a Wi-Fi network depend on the right choice of the AP.

• Standard: Wi-Fi 5 (802.11ac), Wi-Fi 6 (802.11ax), Wi-Fi 6E, Wi-Fi 7 — newer standards give more speed and better operation in interference conditions.
• Bands: 2.4 GHz (longer range, lower speed), 5 GHz (higher speed, shorter range), 6 GHz (Wi-Fi 6E, clean airtime).
• Managed vs standalone: a managed AP is controlled from a controller (for offices and data centers), a standalone one is configured on each device separately.
• PoE power: IEEE 802.3af/at/bt — power over the Ethernet cable, without a separate outlet.
• Clients: number of simultaneous connections — from 20 (home) to 500+ (enterprise).
• Security: WPA3, 802.1X, guest network isolation — critical for CII facilities.

How a Wi-Fi access point works

An AP converts a wired Ethernet signal into radio waves and back. Client devices connect via the 802.11 protocol and receive an IP address through DHCP. An access point does not perform routing — it works as a "wireless switch", forwarding frames between the air and the wired network.

• Client density: Wi-Fi 6 supports 500+ devices per AP thanks to OFDMA.
• Coverage range: 2.4 GHz — up to 100 m, 5 GHz — up to 30 m, 6 GHz — up to 15 m in open space.
• Channels: 2.4 GHz — 3 non-overlapping (1, 6, 11), 5 GHz — up to 25 non-overlapping channels.
• Roaming: 802.11r/k/v — seamless transition between APs without session interruption (important for voice applications and video conferencing).
• Band Steering: automatic transfer of clients from 2.4 to 5 GHz — relieves the airtime.

How to choose a Wi-Fi access point

Determine the number of clients, the coverage area and security requirements. For a small office — a standalone AP. For a corporate network — a managed AP with a controller.

• Wi-Fi 5 (802.11ac): up to 3.5 Gbit/s, 5 GHz, MU-MIMO — sufficient for offices with low client density.
• Wi-Fi 6 (802.11ax): up to 9.6 Gbit/s, 2.4/5 GHz, OFDMA, TWT — best operation in interference and high density.
• Wi-Fi 6E: 6 GHz band added — clean airtime, minimum interference, ideal for medical and educational institutions.
• Wi-Fi 7 (802.11be): up to 46 Gbit/s, 2.4/5/6 GHz, 320 MHz — the newest standard for demanding applications.
• Managed: controller (UniFi Controller, Cisco WLC) — centralized management for 10+ APs.
• Standalone: configuration on each AP separately — for small networks up to 5 APs.

Where "Wi-Fi access point" is used

Wi-Fi access points are in demand when building and operating network infrastructure: in data centers, offices, at critical information infrastructure (CII) facilities, in banks and state corporations, as well as in hotels, medical and educational institutions.

• Office of 10–50 people: 2–3 Wi-Fi 6 APs with PoE managed from a controller — full office coverage.
• Office of 50–200 people: 5–10 Wi-Fi 6 APs, a controller, banding — high client density.
• Hotel: an AP in each room plus common areas, a guest portal with SMS/email authorization.
• Warehouse: AP with an external antenna and an industrial enclosure, coverage up to 500 m.
• Hospital: Wi-Fi 6E, minimum interference, support for medical devices.
• Industry: AP with an extended temperature range and IP67 protection.

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.

• Installation: ceiling/wall, height 2.5–3 m, coverage zone — wrong placement creates "dead zones".
• Security: WPA3-Enterprise, 802.1X via RADIUS, guest VLAN isolation — mandatory for CII facilities.
• Monitoring: cloud controllers (Meraki, UniFi) — remote management and analytics.
• GOST R 57652 (wireless networks), SP 120 (low-current networks) — Wi-Fi security requirements per GOST for CII facilities.

Supply and KTRU codes

Within state and corporate procurement, Wi-Fi access points are supplied under Federal Law 44-FZ and 223-FZ. KTRU code: 43291400000 — Wireless communication equipment.

Fintech JSC provides certificates of conformity, TR CU declarations and warranty obligations.

Detailed description and purpose

A Wi-Fi access point 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 wireless access point 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.

Typical use cases

Wi-Fi access points are used in various industries and at different facilities. The choice of a specific solution depends on the scale, operating conditions and security requirements.

• Corporate office: managed APs with a controller, WPA3, VLANs for guests and employees.
• Industrial facility: AP with IP67 protection and an extended temperature range (-40..+60 °C).
• Medical institution: Wi-Fi 6E, minimum interference, support for medical IoT devices.
• Educational institution: high client density (students), a guest portal, content filtering.
• Hotel: an AP in each room, a guest portal with authorization, roaming between floors.

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 wireless access point 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 Wi-Fi access points 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.
