Choosing the right equipment for creating a wireless network is a task that often confuses even experienced users, who are overwhelmed by the technical specifications. The market is oversaturated with models from dozens of manufacturers, each promising incredible speed, range, and connection stability. However, following the marketing hype can lead to purchasing a device that won't cover the needs of your specific space or the number of connected devices.
First of all, it's important to clearly distinguish between a router and an access point, as these devices perform different functions, although they are often combined in a single housing. A router routes traffic between the local network and the internet, assigns IP addresses, and provides security, while an access point access point An access point (AP) acts as a bridge, converting a wired signal into a wireless one. If you already have a powerful router, but it doesn't cover distant rooms, you need an additional access point, not a second router.
Choosing the wrong equipment can result in constant connection drops and low speeds, which is especially critical for remote work or 4K streaming. In this article, we'll take a detailed look at which parameters to prioritize to avoid overpaying for unnecessary features or, conversely, skimping on critical performance.
⚠️ Attention: Configuration interfaces and available features may vary depending on the firmware version of a specific model. Always consult the manufacturer's official documentation before making any changes to the network configuration.
Key technical standards and frequency ranges
The first and most important selection criterion is support for current wireless communication standards. Currently, the de facto standard is Wi-Fi 6 (802.11ax), which provides high throughput and efficient operation in noisy environments. Older devices of the standard Wi-Fi 5 (802.11ac) They are still available for sale, but their purchase is only justified on a very limited budget, as they are less capable of handling multiple clients at once.
The second critical aspect is frequency range. Most modern access points are dual-band, operating simultaneously on both 2.4 GHz and 5 GHz frequencies. The 2.4 GHz frequency offers better wall penetration, but has a narrow channel and is susceptible to interference from household appliances like microwaves. Conversely, the 5 GHz band offers high speed and stability, but the signal attenuates more quickly when passing through obstacles.
For modern tasks such as watching high-definition video streaming or online gaming, 5 GHz support is a mandatory requirement. Ignoring this fact will result in you not being able to take advantage of the high-speed plan from your provider. Also, it's worth paying attention to the availability of technology Beamforming, which allows the access point to focus the signal directly on the client device, rather than scattering it in all directions.
- 📡 Wi-Fi 6 (AX) - ensures maximum efficiency and speed in densely populated areas.
- 📡 Dual-band — a prerequisite for separating smart home and multimedia traffic.
- 📡 Beamforming — a technology that improves signal quality for remote clients.
- 📡 MU-MIMO - allows you to transfer data to several devices simultaneously, rather than one at a time.
Antennas: external or built-in?
One of the most common questions when choosing equipment concerns the type of antennas. Many users mistakenly believe that the number of antennas directly correlates with range, but this is not entirely true. Antennas in modern access points often act as elements of a MIMO (Multiple Input Multiple Output) system, increasing channel throughput, not just range.
External antennas typically have higher gain (measured in dBi) and can be replaced with more powerful or directional antennas as needed. This makes devices with external antennas more flexible for use in specific environments, such as long corridors or open areas. Meanwhile, access points with integrated antennas are more aesthetically pleasing and take up less space, but their coverage area is strictly fixed by the manufacturer.
If your goal is to cover a large area with minimal obstructions, a model with external antennas may be the best choice. However, for a typical apartment or office with plasterboard partitions, modern models with hidden antennas They often work just as well, providing uniform coverage without “dead zones”.
Usage scenarios: home, office or street
The choice of a specific model depends directly on the specific environment it will be used in. Home environments typically involve 10-30 connected devices, including smartphones, laptops, TVs, and smart home gadgets. For such environments, purchasing enterprise-grade equipment with a complex management system is overkill, unless you plan to build a sophisticated mesh system.
For office spaces, the number of simultaneous connections and seamless roaming capabilities are critical. Offices with dozens of employees simultaneously using video conferencing and cloud services require access points that support the standard. 802.11k/v/rThese protocols allow devices to quickly switch between access points without losing connection as they move around a building.
A separate category is outdoor access points. They must have the appropriate dust and moisture protection class, usually designated as IP67 or IP68These devices feature a reinforced housing, UV protection, and often a built-in heater for operation in low temperatures. Using a standard home access point outdoors, even under a canopy, will quickly cause it to fail due to condensation and temperature fluctuations.
| Type of premises | Key requirements | Recommended standard | Installation Features |
|---|---|---|---|
| Apartment / House | Easy to set up, design | Wi-Fi 5 / Wi-Fi 6 | Tabletop or wall-mounted |
| Office / Coworking | Roaming, many clients | Wi-Fi 6 (AX) | Ceiling installation |
| Warehouse / Production | Range, reliability | Wi-Fi 5 / Wi-Fi 6 | High placement |
| Street / Terrace | IP67 protection, frost resistance | Wi-Fi 5 / Wi-Fi 6 | Sealed housing |
⚠️ Attention: When installing outdoor access points, be sure to use a lightning rod and grounding, even if the device has surge protection. A direct lightning strike or interference can damage not only the access point but also the network equipment connected to it inside the building.
Transmitter power and coverage area
Many users look for an access point with maximum transmit power, believing this will solve all connection issues. However, blindly increasing power isn't always the solution. The signal from a powerful access point may reach a client in a distant room, but the return signal from a smartphone with a weak antenna simply won't be able to "break through." This leads to a situation where the device displays a full signal strength, but the internet connection doesn't work.
A more effective approach is to carefully place the equipment and use multiple, lower-power access points working in tandem. Modern systems allow you to adjust the transmitter power individually for each band to avoid interference between adjacent access points. Optimal power settings are often more important than maximum power settings.
It's also worth considering the wall material. Reinforced concrete floors and walls with metal reinforcement almost completely block the 5 GHz signal. In such cases, network planning The choice of a specific router model becomes more important. Additional cabling may be required to install access points in different rooms.
The myth of "breaking through" three walls
The physics of radio wave propagation are such that no civilian access point can reliably penetrate three load-bearing concrete walls with rebar at high speed. If you're promised a 100-meter range through concrete, that's just marketing. For such cases, there are special directional antennas or cable systems.
Brands and price segments
The network equipment market can be roughly divided into three segments: budget, mid-range, and enterprise. The budget segment is dominated by brands like Tenda, Mercusys and basic models TP-LinkThey offer good value for money for small apartments, but their software is often limited in functionality, and stability under heavy load can be poor.
The middle segment, represented by companies Keenetic, Asus, TP-Link (Archer/Omada series) And MikroTik, offers the best balance. Here you get advanced features, regular security updates, and flexible customization options. For example, devices Keenetic are famous for their modular operating system, and MikroTik It provides capabilities comparable to professional equipment at an affordable price, although it requires in-depth knowledge to set up.
Corporate segment (Ubiquiti UniFi, Aruba, Cisco) is aimed at businesses. These devices often require a separate controller for management and configuration. They offer superior reliability and scalability, but their cost and operational complexity make them overkill for typical home use.
FAQ: Frequently Asked Questions
Can a regular access point be used as a router?
A pure access point can't function as a router, as it lacks routing, NAT, or DHCP server capabilities (although some models have a simplified router mode). To use it as the primary internet sharing device, you'll need a separate modem or router that performs these functions.
How many access points are needed for a 100 sq.m. apartment?
For a standard 100-square-meter apartment, one high-quality dual-band access point installed in the center of the living space is usually sufficient. If the apartment has many load-bearing walls or is elongated, a second access point may be needed to ensure a stable signal in distant rooms.
Does the number of connected devices affect the speed?
Yes, it does. Every connected device competes for airtime. Even if devices aren't actively transmitting data, they exchange service packets. Technologies MU-MIMO And OFDMA The Wi-Fi 6 standard helps minimize this effect, allowing it to serve more clients simultaneously without sacrificing performance.
Do I need to update my access point firmware?
Absolutely. Manufacturers regularly release updates that not only add new features but also patch security vulnerabilities. Neglecting updates can leave your network vulnerable to external attacks. It's recommended to check for updates at least quarterly.
Which is better: a mesh system or multiple access points?
A mesh system is essentially a collection of access points running software for seamless operation. If you need to cover a large area and want devices to seamlessly switch between them, a mesh system is the best choice. Regular access points can also be combined into a single network, but setting up seamless roaming in them may be more complicated or require equipment from a single vendor.
