What are the capabilities of a cellphone repeater?
Cellphone repeaters are used to increase the quality of reception. They are equipped with multiple antennas and amplifier to boost the reception to cellphone towers in the area. One can find more information about cellphone repeaters from resources such as Wikipedia.
What is spatial multiplexing in MIMO?
MIMO is generally used for enhancing data transmission capacity, where multiple antennas are used to send the data and the more antennas means the more data transfer speed. Suppose, you have 5 antennas in the transmitting side an 5 antennas in the receiving side and you have a data stream of 100 bits for transmission. If you use each antenna to send 20 bits each then it would take five times less to send all the data if you only used a single antenna. By the use of MIMO increasing the data transmission speed is known as spatial multiplexing.
Which two versions of the 802.11 technologies can use multiple antennas at both the access point and network adapter?
802.11n and g. The most recent to be deployed is 802.11n. They are wireless network protocols. 802.11n standard uses two antennas at both ends of the transmission and can use 802.11b/g/n standards. page 479 in the A+ Guide to Hardware 5th edition book.
What is a trunk Port?
A trunk port is a port on a switch that can be assigned to carry multiple VLANs across switches or increase overall bandwidth/throughput.
What are the advantages of microwave transmission line?
Advantages: No cables needed multiple channels available, wide bandwidth.Disadvantages: Line-of-sight will be disrupted if any obstacles, such as new buildings, are in the way. Signal absorption by the atmosphere. Microwaves suffer from attenuation due to atmospheric conditions. Towers are expensive to build
Where is the transmission solenoid located at on a 1998 z34?
There are multiple transmission shift solenoids. All of them are found inside the transmission itself and are accessed by removing the transmission pan and filter.
Transmission involves one transmitter and multiple receivers?
point-to-multipoint
What transmission that involves one transmitter and multiple-undefined receivers?
broadcast
A form of transmission that allows multiple signals to travel simultaneously over one medium is known as?
A form of transmission that allows multiple signals to travel simultaneously over one medium is known as multiplexing
Can you list two reasons that modulation is used for communications transmissions?
To send multiple messages by changing the carrier signal. To be able to use smaller antennas higher frequency means smaller antenna
Which two features are supported at all three levels of the cisco three layer hierarchical?
QoS. Link aggregation allows multiple switch port links to be combined so as to achieve higher throughput between switches
I have a pajero 2008 engine light is on sometime when it is on transmission is delaying once off transmission is ok what can be the reason and there is any danger on the transmission?
There are multiple reasons why a 2008 Pajero could have the engine light on. The transmission could be one reason the light is on.
