what is tpc in wireless

by Delfina Frami Published 3 years ago Updated 2 years ago

Controllers use the TPC (Tx Power Control) algorithm to determine whether the power of an AP needs to be adjusted down. Reducing the power of an AP helps mitigate co-channel interference with another AP on same channel in close proximity.Mar 17, 2013

What does TPC mean in networking?

TPC, Transmit Power Control, by which 2 devices initiating a communication in the 5 Ghz spectrum will negotiate so that their respective power level is as low as possible, just loud enough to hear each other (so that your noisy 50 mW access point does not disturb the poor 60 WATTS radar sitting next door!!). Where do you configure TPC?

What is the difference between TPC and DTPC?

- DTPC, that's Dynamic Transmit Power Control, looks close to TPC but has no direct relation. It is a Cisco proprietary system. With DTPC, your Cisco access point transmits to your Cisco CCX compliant clients information about which power level to use... Yes, it's close to the other two protocols explained above...

Is DTPC a Cisco proprietary system?

It is a Cisco proprietary system. With DTPC, your Cisco access point transmits to your Cisco CCX compliant clients information about which power level to use... Yes, it's close to the other two protocols explained above... However DTPC will be dynamic as the client moves closer or further away from the AP.

What is TPC in WIFI?

Transmit Power Control (TPC) or sometimes called Dynamic Power Control (DPC) is a mechanism used in radiocommunications to reduce the power of a radio transmitter to the minimum necessary to maintain the link with a certain quality. TPC is used to avoid interference into other devices and/or to extend the battery life.

What is dynamic transmit power control Dtpc and how does it work?

Dynamic transmit-power control (DTPC) is critical to improve spectral efficiency and reduce interference in wireless local area networks (WLANs). DTPC schemes typically use signal-to-noise-ratio (SNR) information and require exchange of information between transmitters and receivers.

What is ieee802 11h?

IEEE 802.11h-2003, or simply 802.11h, refers to a 2003 amendment added to the IEEE 802.11 standard for Spectrum and Transmit Power Management Extensions. It addresses problems like interference with satellites and radar using the same 5 GHz frequency band.

What is 802.11 H enable or disable?

802.11h allows wireless clients to move to the new channel used by the access point by notifying the wireless clients about the change of channel. This minimizes data loss when the 5 GHz radio moves to the new channel. To configure 802.11h navigate to Management > Advanced > Wireless Settings > 5 GHz.

What is Dtpc support?

Client devices using dynamic transmit power control (DTPC) receive the channel and power level information from the access points and adjust their settings automatically.

What is the best RTS threshold setting?

The recommended standard of the RTS threshold is around 500. A low threshold implies RTS packets are transferred more frequently and the throughput of the packet is on the lower side.

What is 802.11 i and what aspect of WLANs does it deal with?

The IEEE 802.11i is an amendment to the 802.11 standard. 802.11i supports data communications security for Wireless Local Area Networks (WLANs). This amendment defines processes for wireless authentication, key management, and packet encryption.

How do I turn on my radio WiFi?

How to Enable a Wireless RadioClick "Start," then "Control Panel" and select "System and Maintenance." Click "Device Manager" from the list and click the small arrow next to "Network adapters" to display the list of devices. ... Find the wireless button on your computer. ... Press the wireless button to turn it on.

Overview

APs can broadcast and operate using a number of different power levels. The higher the power is set on our APs, the bigger our coverage cell.

Configuration

In most cases, TPC doesn’t require any configuration to work. There might however be situations where the TPC algorithm needs to be tweaked.

What is a WLC?

A Cisco Wireless Lan Controller (WLC) on 8.0 software is used only for configuration reference.

Is DTPC a Cisco CCX?

It is a Cisco proprietary system. With DTPC, your Cisco access point transmits to your Cisco CCX compliant clients information about which power level to use... Yes, it's close to the other two protocols explained above... However DTPC will be dynamic as the client moves closer or further away from the AP.

What is TPC in AP?

Controllers use the TPC (Tx Power Control) algorithm to determine whether the power of an AP needs to be adjusted down. Reducing the power of an AP helps mitigate co-channel interference with another AP on same channel in close proximity.

What is the default power assignment method for TPC?

Like DCA, we can select power assignment method for either TPC “Automatic”, “On Demand” or “Fixed” options. Default is “Automatic”.

How many APs do you need to run TPC?

The more APs hear each other at -70dBm or greater, the better the TPC algorithm functions. Minimum requirement for TPC is that a single AP needs to be heard by at least 3 other APs at -70dBm or greater. Therefore you must have at least 4 APs total.
