Very High Throughput (VHT)
Cards in this deck (10)
- 1If the 2 80Mhz channels are adjacent, then it is referred to as a:160 MHz channel
- 2If the 2 80Mhz channels are not adjacent, then it is referred to as a:80+80 MHz channel
- 3The following ammendment introduced 64-QAM modulation802.11a
- 4Essentially performs a phase shift that can differentiate eight different levels and also performs an amplitude shift, which can also differentiate eight different levels64-QAM i
- 5can transmit 8 bits per subcarrier compared with the 6 bits that were transmitted with previous technology, a speed increase of 33 percent is achieved solely by deploying this feature256-QAM signal
- 6When implementing 256-QAM signal , it achieves that high data rates by increasing:signal to noise ratios
- 7What is beamforming used for on single-user MIMO and MU MIMO?to focus a signal to a client (s)
This focused transmission (s) should increase the level of the signal that the client receives - 8how many spatial steams are mandatory on 802.11ac:1 for clients, 2 for APs
- 9What is the guard interval value on 802.11ac800 nanosecs (long) and 400 nanosecs (short)
