hw many total channels are available for 802.11g wireless networks?

11

which data transmission rate is defined by the IEEE 802.11b wireless standard?

11 Mbps

which of the ff are frequencies defined by 802.11 committees for wireless networking? select two

2.4 GHz 5.75 GHz

how many total channels are availb,e for 802.11a wireless networks?

23

what is the frequency of 802.11a networking?

5.75 GHz

you are designing a wireless network for a client. your client needs the network so support a data rate of at least 54 Mbps. in addition, the client already has a wireless telephone system installed that operates 2.4 GHz. which 802.11d standard will work in this situation?

802.11a

which IEEE standard describes wireless communication?

802.11b

which IEEE wireless standards specify transmission speeds up o 54 Mbps? select two

802.11g 802.11a

you are designing an update y\to your client's network. The existing wireless network uses 802.11b equipment; which your client complains runs too slowly. She wants to run up to 600 Mbps. due to budget constraints, your client wants to upgrade only the wireless access points in the network this year. Next year, she will upgrade wireless network boards in her user's workstations. She has also indicated that the system must continue to function during the transition period. which 802.11 standard will work best in this situation?

802.11n

you have been contacted by OsCorp to recommend a wireless Internet solution. The wireless strategy must support a transmission range of 1,200 feet, use a frequency range of 5 GHz, and provide the highest possible transmission speeds. which of the ff. wireless solutions would you recommend?

802.11n

which technologies are used by the 802.11ac standard ti increase network bandwidth?

eight MOMO radio streams 160 MHz bonded channels

your organization uses an 802.11b wireless network. recently, other tenants installed the ff. equipment in your building: -A wireless television distribution system running at 2.4 GHz -A wireless phone system running at 5.8 GHz -A wireless phone system running at 900 MHz -An 802.11a wireless network running in the 5.725 - 5.850 GHz frequency range. -An 802.11j wireless network uniting in the 4.9 - 5.0 GHz frequency range since the equipment was installed, your wireless network has been experiencing significant interference. Which system is to blame?

the wireless TV system
