Overview of an Access Point
An AP is a device that allows the wireless connection of multiple devices to a network. They are used in environments where it is not practical or possible to use cables to connect devices to the network, such as homes, offices, hotels, and airports, among others.
The operation of an access point is quite simple. The device connects to an existing wired network and then creates a wireless network that devices can connect to. They can also extend the range of an existing wireless network, allowing devices to connect from a greater distance.
It is important to note that they are not the same as wireless routers, although both devices are used to create wireless networks. A wireless router is a device that connects a local network to the Internet and distributes the WiFi signal. An AP, on the other hand, is used to extend the coverage of the wireless signal and allow the connection of more devices.
AP Operation
The operation of an access point is relatively simple, but it is important to understand some basic concepts to comprehend how it is configured and how it is used.
- Network Connection: The AP connects to an existing wired network using an Ethernet cable. It must be connected to a switch or router, as this will allow it to obtain an IP address and connect to the Internet.
- Creating a wireless network: Once connected to the wired network, the AP creates a wireless network that devices can connect to. This network is identified by a network name (SSID) and a password.
- Signal coverage: The access point has a limited range, which means that devices that are out of range will not be able to connect to the wireless network. To extend the range of the signal, multiple APs can be used, creating a larger wireless network and allowing more devices to connect.
- Security: It is important to secure the wireless network using different security measures, such as data encryption and MAC address filtering. These measures can help prevent unauthorized devices from connecting to the network and help protect data that travels over the network.
Types Of APs
There are different types of APs, each with its own characteristics and specific uses. They are designed to meet specific wireless connectivity needs in different environments and situations.
- Indoor: These APs are designed for indoor use, such as homes, offices, or shopping malls. They generally have a limited range and can support a limited number of simultaneously connected devices.
- Outdoor: For use outdoors, such as in parks, college campuses, or parking lots. They are more resistant to adverse weather conditions and have a wider range than indoor ones.
- Business: They are usually more expensive than consumer ones and can support a greater number of devices connected simultaneously. In addition, they offer advanced management features such as security policy configuration and bandwidth allocation.
- High-density: They are designed to support a large number of simultaneously connected devices, such as in stadiums, convention centers, or airports. They tend to be more expensive than the standard ones and have a higher processing power and memory.
- Mesh: These APs use a network of interconnected nodes to provide broader and more consistent wireless coverage. The nodes communicate with each other to extend the range of the wireless network and ensure that devices are always connected to the strongest signal.
How To Configure an Access Point?
Setting up an access point is a relatively simple process that can be done by following these steps:
- Connect the AP to the network: To get started, connect the AP to the network using an Ethernet cable. The AP must be connected to a router or other network device that has an Internet connection.
- Access the configuration page: Once the AP is connected to the network, access the configuration page. This can be done by entering the IP address of the AP in a web browser.
- Set up the wireless network: Within the settings page, look for the wireless network settings section. There you can configure the name of the network (SSID), the password, and the type of security you want to use.
- Configure other options: In addition to wireless network settings, you may want to configure other options such as LAN port settings, IP address assignment, DHCP settings, etc.
- Save Changes: Once you’ve made all the changes you want, be sure to save your changes before exiting the settings page.
- Test the connection: Finally, test the wireless connection with a device, such as a mobile phone or laptop, to make sure everything is working properly.
If you are having difficulty configuring the AP, refer to the device’s user manual or contact technical support for further assistance.
APs Security
Security in APs is essential to protect a wireless network from unauthorized access and possible cyber attacks. Some measures you can take to improve access point security are:
- Set a strong password: Set a strong and unique password for the AP, and avoid using easy-to-guess passwords like «password» or «123456». It is recommended that the password include upper and lower-case letters, numbers, and symbols.
- Use strong encryption: Set up WPA2 or WPA3 encryption instead of using WEP, as the latter is less secure. Network encryption encrypts data transmitted between devices and the AP.
- Hide SSID: Hide the wireless network name (SSID) so that it is not visible to nearby devices. This makes it difficult for someone to try to access the network without authorization.
- Limit access: Set the AP to only allow access to specific devices via MAC address. In this way, only devices whose MAC addresses are registered will be able to connect to the network.
- Update Firmware: Make sure your firmware is up to date. Firmware updates often include security enhancements and fixes for known vulnerabilities.
- Control the range of the signal: Set the signal to cover only the necessary area. This can help prevent the signal from spreading too far and allowing unauthorized access.
- Use a guest network: If you need to provide Internet access to visitors, set up a separate guest network from the main network. This will help protect the main network from potential external threats.
