In today's world, wireless internet has become as essential as electricity or running water. However, when it comes to building a high-quality network in a large home or office, users often encounter the term Wi-Fi hotspot, confusing it with a regular home router. Understanding the differences between these devices is critical for those who want to ensure stable coverage without "dead zones."
In essence, Access Point An access point is a device that broadcasts a wireless signal, creating a bridge between a wired local network and Wi-Fi clients (smartphones, laptops, tablets). While a router is a dispatcher, distributing traffic between the internet and internal devices, an access point is a transmitter, expanding the signal's range.
Using specialized devices instead of a router's built-in antennas allows you to scale your network to any size. You can install one access point in the hallway, another in the kitchen, and a third in the back bedroom, creating a seamless space where switching between signal sources is seamless.
Key differences between an access point and a router
The main misconception is that these devices are completely interchangeable. Router A router is a multifunctional gadget that not only distributes Wi-Fi but also manages IP addresses (DHCP), provides security (firewall), and connects your home network to your ISP. An access point lacks these features; it merely extends an existing network.
Imagine this: you have a fiber optic cable from your ISP. You connect it to a powerful router located near your front door. The Wi-Fi signal from it reaches the middle of the apartment, but in the far room, the internet drops. This is where... Access PointYou run an Ethernet cable from the router to a distant room, connect the access point there, and it distributes Wi-Fi using the router's internet connection.
In the corporate segment, using separate access points is the de facto standard. This allows for centralized management of dozens of devices, setting up guest networks, and collecting analytics without overloading the main router.
- 📡 Router creates a network and distributes IP addresses, while the access point only broadcasts the signal.
- 🏢 Scalability: Multiple access points can be connected to a single router to cover large areas.
- 🔌 Connection: the router connects to the provider (WAN), and the access point receives the Internet via a LAN cable from the router.
⚠️ Attention: Many modern routers have an "Access Point" mode. If you try to use such a router as a default gateway in this mode, routing and IP address distribution (DHCP) functions will be disabled, and internet access will not be available to devices without additional equipment.
It's important to note that in access point mode, the device ceases to be the "smart hub" of your network. It becomes a transparent bridge. This means all security settings, parental controls, and traffic prioritization must be configured on the main router.
Wi-Fi standards and their impact on data transfer speeds
When choosing equipment, it's important to pay attention to the supported wireless standards. Older devices can become a bottleneck, limiting speed even if you have a fast plan from your provider. Modern Wi-Fi standards provide not only high speed, but also connection stability with a large number of connected clients.
The most relevant standard today is Wi-Fi 6 (802.11ax), which replaced Wi-Fi 5 (802.11ac)It uses OFDMA technology, which allows for more efficient channel resource distribution among multiple devices. This is especially important in offices or apartment buildings, where the airwaves are clogged with signals from neighboring networks.
The next step in evolution was Wi-Fi 7, which promises even higher speeds and minimal latency, but its adoption is only just gaining momentum. For most home and office tasks, current-generation hardware is sufficient.
| Standard | Year of implementation | Max. speed (theoret.) | Frequency ranges |
|---|---|---|---|
| Wi-Fi 5 (802.11ac) | 2014 | up to 6.9 Gbps | 5 GHz |
| Wi-Fi 6 (802.11ax) | 2019 | up to 9.6 Gbps | 2.4 GHz, 5 GHz |
| Wi-Fi 6E | 2020 | up to 9.6 Gbps | 2.4, 5, 6 GHz |
| Wi-Fi 7 (802.11be) | 2026 | up to 46 Gbps | 2.4, 5, 6 GHz |
When purchasing equipment, it is worth considering that access point It must match your router's class. If you connect a modern Wi-Fi 6 access point to an older Wi-Fi 4 router, the entire system will operate at the speed of the weakest link.
Home and office use cases
At home, access points are most often needed in large apartments, cottages, or houses with thick brick and concrete walls. Wi-Fi signals have difficulty penetrating such obstacles, and even a powerful router can't penetrate three load-bearing walls.
Access points are almost always essential in office spaces. Open spaces require uniform coverage so employees can move around with laptops or tablets without losing connection to the server or video conference. It's not just speed that matters here, but also roaming - the ability of the device to quickly switch between points.
Access points are also indispensable for creating guest networks. You can set up a separate SSID (network name) for visitors, restricting their access to internal company resources or home files while still providing internet access.
- 🏠 House: eliminating dead zones in distant rooms, in the kitchen or in the garage.
- 🏢 Office: Providing communications for conference rooms, warehouses and workplaces.
- 🏨 Public places: Organization of hotspots in cafes, hotels and shopping centers with authorization.
⚠️ Attention: Access point configuration interfaces and functionality may vary depending on the manufacturer and firmware version. Always consult the official documentation for your specific model before making any changes to the network configuration.
It's important to plan the equipment placement correctly. It's recommended to mount access points on the ceiling or high on walls, as their antennas are often omnidirectional and designed to project signals downward.
Features of installation and laying of cable infrastructure
The performance of a wireless network directly depends on the quality of its "wired foundation." Since the access point receives internet via cable, wiring must be done responsibly. Using cheap or damaged cables can lead to unstable performance and reduced speed.
To connect modern access points that support technology PoE (Power over Ethernet), no separate power supply is required. Power is supplied directly via twisted-pair cable from the switch or injector. This simplifies installation and allows placement of devices in locations without nearby 220V outlets.
When laying cable, it's important to adhere to technical standards: avoid bending the twisted pair at sharp angles, avoid overstretching it, and protect it from direct sunlight if the cable is located outdoors. For outdoor installations, use cable marked with the markings. Outdoor, which has additional protection from ultraviolet rays and moisture.
☑️ Check before installing the access point
The cable length from the switch to the access point should not exceed 100 meters. If a longer distance is required, fiber optics or additional active signal repeaters should be used.
Setting up seamless roaming and security
One of the main objectives when installing multiple access points is to set up seamless roaming. Users shouldn't notice their phone switching from one access point to another as they move around the building. To achieve this, all access points should have the same network name (SSID) and password, but operate on different channels.
Technologies 802.11k/v/r They help devices quickly find the best access point and switch to it without losing the connection. However, these standards must also be supported on the client device (smartphone or laptop).
Security issues are also a priority. It is recommended to use an encryption protocol. WPA3 (or WPA2 if your equipment is older). For guest networks, be sure to enable Client Isolation to prevent guest devices from seeing each other or your personal files.
What is AP Isolation?
This is a security feature that prevents devices connected to the same access point from exchanging data with each other. This is ideal for hotels and cafes where users shouldn't have access to other guests' printers or files.
Don't forget to regularly update your access point firmware. Manufacturers frequently release patches that fix security vulnerabilities and improve the stability of the radio module.

Properly selected equipment will last for many years, providing comfortable internet access anywhere in your premises.
Frequently Asked Questions (FAQ)
Can a regular router be used as an access point?
Yes, most modern routers have an "Access Point Mode." In this mode, the router disables routing and DHCP functions, operating solely as an extender of the wired network into a wireless one. This is a cost-effective solution for the home.
How many access points are needed for a 100 sq.m. apartment?
Typically, for an apartment of this size with load-bearing walls, a single, powerful access point or high-quality router located centrally is sufficient. If the layout is complex or the walls are concrete, a second access point in a distant room may be necessary.
Do I need a separate controller to manage access points?
Not always. Many modern systems (for example, TP-Link Omada or Ubiquiti UniFi) allow the use of a software controller that can be installed on a regular computer or server. Some models have a built-in controller at one of the points.
Does the wall material affect the performance of the access point?
Yes, and very much so. Metal, reinforced concrete, and mirrors block Wi-Fi signals. Wood and drywall absorb less. When planning your network, be sure to consider the material of your partitions.
