What is Wireless Access Point?
Wireless Access Points (WAPs) are devices that allow you to connect to a wireless network. They are often used in homes, businesses, and public spaces to provide Internet access without the need for wires or cables.
WAPs typically come in two forms:
- routers
- hotspots
Routers are designed to provide Wi-Fi access throughout an entire home or building, while hotspots are designed to provide Wi-Fi access in a specific area. Both types of WAPs use radio frequencies to transmit data between devices and networks.
What are the Benefits of Wireless Access Points?
There are many advantages to using WAPs, including:
- Increased Mobility: WAPs allow users to move around freely without the need for wires or cables. This makes it easier to work in different locations or use multiple devices within a single network.
- Cost savings: Installing and maintaining a wireless network is generally cheaper than installing and maintaining a wired network.
- Security: WAPs provide an added layer of security as wireless networks are not susceptible to physical tampering or interception the way wired networks can be.
- Convenience: WAPs allow users to access the network from anywhere, making it easy to stay connected while on the go.
What are the Drawbacks of Wireless Access Points?
Although WAPs offer many benefits, there are some drawbacks to using them as well, such as:
- Interference: Wireless networks can be susceptible to interference from other Wi-Fi networks or devices in the vicinity. This could cause slow speeds or connection drops.
- Security: Wireless networks may be more vulnerable to security threats such as hacking or malware due to their open nature.
- Cost: Although WAPs are typically cheaper than wired networks, they can still be expensive depending on the type of equipment needed.
- Range: The range of a wireless network is limited and may not be able to cover large areas. This can be a problem for businesses or homes with multiple floors or rooms.
How Do Wireless Access Points Works in Networking?
Here are the steps involved in how WAPs work:
- Connect the WAP to a modem or other source of Internet connection.
- Set up the wireless network name (SSID). This is what other devices will use when connecting to the network.
- Configure encryption and security settings, such as passwords and encryption protocols.
- Devices that are within range of the WAP will be able to detect and connect to the network.
- Once connected, these devices can access the Internet or other resources on the network.
- The WAP will also manage communication between devices on the network, allowing them to share data or access shared resources.
- The WAP will also manage the flow of traffic, ensuring that each device is able to access the data it needs without slowing down other devices on the network.
Where We Can Use WAPs?
WAPs can be used in homes, businesses, public spaces, and almost any other place that needs wireless network access. Some examples of where WAPs are used include:
- Coffee shops and restaurants
- Hotels and resorts
- Airports
- Universities and schools
- Hospitals
- Office buildings
What is the Right Place to Put Wireless Access Points?
There are several factors to consider when determining the best place to install a WAP. These include:
- Signal strength: The signal should be strong enough to cover the area where it will be used.
- Interference: Try to avoid placing the WAP near other wireless devices or networks, as they can interfere with each other’s signals.
- Obstructions: Physical obstructions such as walls, furniture, and other objects can weaken the signal. Try to place the WAP in an open area or near a window if possible.
- Area of coverage: Make sure that the WAP has enough coverage to cover the entire area that needs access. This may mean installing multiple WAPs in different locations.
- Ease of use: Try to place the WAP in an easily accessible location that is easy for users to access. For example, a business may choose to place the WAP near the reception desk for easy access.
Which one of the following is the frame type sent to discover APs within the signal range of a wireless client?
- Scan
- Probe
- Beacon
- Discovery
The frame type sent to discover APs within the signal range of a wireless client is Probe.
But Why?
Probes are frames that are sent by a wireless device trying to connect to an access point (AP). The probe frame contains the name of the desired network, which is broadcasted in order for any AP within range to respond with a beacon frame, which contains the network information for a given AP.
If the wireless device receives multiple beacon frames, it will select an appropriate AP to connect to based on the signal quality, encryption method, and other factors. Probes are also used by access points to detect and authenticate connected clients.
In this case, the probe frame is sent by the AP and is responded to by the client with an authentication frame. This process is known as 802.11 authentications.
