What are the design goals of WLAN?
Most wireless LANs use radio frequencies (RF) to function (normally in the range of 2.4GHz).
Airwave congestion contributes to data rates for a wireless LAN.
Integrity and Reliability.
Radio interference can cause degradation in throughput.
Is wireless security better than wired?
Whether a wired or wireless security system is better will depend on what you need from a security system. Hardwired alarm systems have an edge on reliability, while wireless systems provide a more streamlined installation and can be used in places where wired systems can’t.
What is WLAN and its advantages and disadvantages?
Light of sight is not required for propagation. The signal is not blocked by any objects like buildings, trees etc. High data rate, as coverage area is small.
What are the advantages of WLAN?
The most obvious advantage of a WLAN is that devices can connect wirelessly, eliminating the need for cables. This allows homes and businesses to create local networks without wiring the building with Ethernet. It also provides a way for small devices, such as smartphones and tablets, to connect to the network.

Is wireless better than wired?
Wired networks are generally much faster than wireless networks. … This is mainly because a separate cable is used to connect each device to the network with each cable transmitting data at the same speed. A wired network is also faster since it never is weighed down by unexpected or unnecessary traffic.

Is WLAN and WiFi the same thing?
Answer: Both Wi-Fi (wireless fidelity) and WLAN (wireless local area network) mean the same — they both refer to a wireless network that can transfer data at high speeds. … You can also set a name for your Wi-Fi network and assign a password to it for security.
What does a WLAN card do?
A Wireless Local Area Network (WLAN) card is a device that allows a computer to connect to wireless networks. … Wireless networks are sometimes called Local Area Wireless Networks (LAWN). Wireless networks often use a modem to give WLAN-capable computers access to the Internet.
What are the pros and cons of WIFI?
Pros and Cons to using Wi-Fi and Cellular InternetPROS: Typically faster than cellular internet. Signal stability. … CONS: Not as easily accessed as cellular. For “public” hotspots, extreme security risks. … PROS: Mobility – ability to move the connection with the device being used. … CONS: In many areas, major speed variances based on the tower being used.
What are the disadvantages of wireless networks?
