What is ht and VHT in wi-fi?

High throughput (HT) and Very High Throughput (VHT) Are Terms Associated With The Evolution of Wi-Fi Standards, Specifically Pertaining To the IEEE 802.11n (Wi-Fi 4) and Ieee 802.11ac (Wi-Fi 5) Standards, respectively . These standards introduce improvises in data rates, channel bonding, and other technologies to enhance the overall throughput and performance of Wi-Fi networks.

High throughput (HT) – IEEE 802.11N (Wi -Fi 4):

  1. Introduction:
    • High throughput (HT) is a feature introduced in the ieee 802.11n standard, designed to provide Higher Data Rates and Improved Performance Compared to Earlier Wi-Fi Standards.
  2. Key features:
    • Channel Bonding: HT Allows the Aggregation of Multiple Adjacent Channels To Increase The Available Bandwidth. This is Known as Channel Bonding, and it enhances data rats by EnaBubling the simultaneous transmission of multiple data streams.
    • Mimo (multiple input, multiple output): HT supports Mimo Technology, Allowing Multiple Antennas at Both the Transmitter and Receiver Ends. MIMO IMPROVES SIGNAL QUALITY, RAGE, AND DATA RATES by exploitation space diversity.
    • Advanced Modulation Schemes: HT Introduces More Advanced Modulation Schemes, Such As 64-Qam (Quadrature amplitude modulation), Which Allows the Transmission of More Data Bits Per Symbol, Increasing Overall Throughput.
    • Frame aggregation: HT Incorporate Frame Aggregation Techniques, EnaBling the Grouping of Multiple Frames Into A single transmission unit. This reduces overhead and improves efficient.

Very high throughput (VHT) – IEEE 802.11ac (Wi -Fi 5):

  1. Introduction:
    • Very high throughhput (VHT) is the Next Evolution of Wi-Fi Standards, introduced in the Ieee 802.11ac standard. It builds upon the Foundation Laid by Ht and introduces Further Enhancements to Achieve Even Higher Data Rates and Improved Performance.
  2. Key features:
    • Wider Channels: VHT supports Wider Channel Bandwidths, included 80 MHz and 160 MHz Channels. This significantly include the Available Spectrum for Data Transmission.
    • Additional Spatial Streams: VHT extends Mimo Capabilitities by supporting A Higher Number of Spatial Streams. This Allows for Even More Parallel Data Transmission, Further Improving Throughput.
    • Advanced Modulation: VHT introduces Higher-Order Modulation Schemes, included 256-qam, Enabling the Transmission of More Data Bits Per Symbol and Increasing the Overall Data Rate.
    • Multi-USE MIMO (MU-MIMO): VHT Introduces MU-MIMO, ALLOWING A Wi-Fi Access Point to Communicate With Multiple Devices Simultaneously. This enhances the efficiency of the network in scenarios with multiple connected devices.

Summary:

In Summary, Both High Throughput (HT) and Very High Throughput (VHT) ASSE NOTEICING INSTROCATIONS IN Wi-Fi Standards, Introductive Technologies Such As Channel Bonding, Mimo, Advanced Modulation, and Wider Channels To Achieve Higher Data Rates and Improved Overall Performance. VHT, Being A Later Standard, Builds Upon the Foundation Laid by HT, Bringing Additional Features Like Wider Channels and Mu-Mimo to Further Enhance The Wi-Fi Experience. Thesis Advancements Play A Crucial Role in Meeting the Growing Demand For Faster and More Efficient Wireless Connectivity.
