What are the four types of wireless networks?
There are four types of wireless networks — wireless local area networks, wireless metropolitan area networks, wireless personal area networks and wireless wide area networks — each with its own function.
What are wireless examples?
Types of Wireless Communication Some of these terms may be familiar to you: radio and television broadcasting, radar communication, cellular communication, global position systems (GPS), WiFi, Bluetooth and radio frequency identification are all examples of “wireless”, with wildly different uses in some cases.
Which are the troubles with wireless network?
Denial of service – Network attack where large amounts of traffic at a specific target, or through purposely interfering with a WLAN networks connectivity (e.g. through RF interference) Configuration problems – Usually an internal issue with hardware/software is not configured with the proper security protocols.
How many Wi-Fi are there?
The five Wi-Fi technologies are A, B, G, N and AC. B and G use the 2.4 GHz frequency; A and AC use the 5 GHz frequency; and N uses both 2.4 and 5 GHz frequencies. Your choice for your home or business will come down to three: Wireless G, N or AC. Routers that only support Wireless B are no longer manufactured.
What are Wi-Fi protocols?
Wi-Fi (/ˈwaɪfaɪ/) is a family of wireless network protocols, based on the IEEE 802.11 family of standards, which are commonly used for local area networking of devices and Internet access, allowing nearby digital devices to exchange data by radio waves.
What is WLAN and its types?
Wireless LANs (WLANs) are wireless computer networks that use high-frequency radio waves instead of cables for connecting the devices within a limited area forming LAN (Local Area Network). Most WLANs are based upon the standard IEEE 802.11 standard or WiFi.
How many types of Wi-Fi are there?
What is wireless topology?
Overview. The topology of a wireless network is simply the way network components are arranged. It describes both the physical layout of devices, routers, and gateways, and the paths that data follows between them.
How to prepare for a wireless network engineer interview?
To ace wireless network engineer interview questions, you’ll need to invest time preparing for them. While you may be familiar with some or all of the topics discussed here from your experience as a wireless network engineer, you still need to be able to articulate your answers succinctly, through clear communication.
Can a wireless client operate in World mode?
Generally a wireless client can operate only in its Local Regulatory domain as channel and power settings carry for each domain. When World Mode is used, a client can automatically adjust channel and power settings according to the domain it migrates to.
What kind of data can you collect from wireless LAN?
This includes non-802.11 sources such as microwave ovens, cordless phones, etc. You can collect information on key parameters such as Signal strength, Noise, and Data rates that exist in the actual deployment scenario. Based on this, WLANs can be planned and deployed accordingly.
What should I do before installing a wireless LAN?
Relocate the Cisco AirNet equipment as far away as practical from potential sources of EMI/RFI or reorient the point-to-point antennas away from the RFI/EMI emitter. Use a different frequency range for the phone and WLAN. It is suggested that you perform a site survey before you install a WLAN.
