IEEE 802.11ac is a brand new WLAN (WLAN) standard being integrated into wireless devices. Currently, products supporting this standard are available in the market, and various manufacturers have begun to enter the mass production stage. Production and testing engineers must be able to support new 802.11ac test specifications and be compatible with existing WLAN standards and other wireless connection technologies. Based on the draft technical specifications, this article introduces the main prod

MIMO 11n wireless card to buy a router that supports at least 2x2 MIMO, so it doesn't become a bottleneck. According to the current market price such routers are also 200 less than.In addition 11AC is a new thing may not be used in many people, this is required to set up the high-speed mode, I today, I toss a bit, 11AC high-speed mode is required to manually in the configuration of Intel network card, otherwise only 11n speed, how to open the specific lookSelect

These are the default settings for Intel wireless adapters that support 802.11N. These recommended settings can be found on the Advanced menu of intel® proset/wireless software. Property Value 802.11n channel width of band 2.4 Auto (no longer just 20MHz) 802.11n channel width of band 5.2 Auto (no longer just 20MHz) 802.11n mode Enabled (enable) Incompatible with 40Mhz Disable Roaming Init

recovered. In addition, the default. Qar file contains some non-critical files, which have some redundancy.The key to solving this problem is to clarify the significance of the file extension and clearly control the choice of files.The following file is an explanation of the file extension copied from the Quartus II help file. the preceding files can be divided into five types: 1. compile required files: design files (. GDF ,. BDF, edif input file ,. the TDF and OpenGL design files ,. vqm

Qsf is Quartus settings fileContains all the constraints of a US Us Project, including engineering information, device information, pin constraints, compilation constraints, and timing constraints for classic Timing Analyzer. SDC is Synopsys Design ConstraintsThis file is usedTimequest Timing Analyzer time series constraints and Custom reports. In timequest, it is easy to convert the constraints of classic Timing Analyzer into SDC. Under the constraints menu, run generate SDC file from qsf.

the client and the access point is connected in the air. Air communication is processed through L2 QoS Based on the 802.11e standard. 4. Downstream and Upstream There is a significant difference between downstream from the access point to the client and upstream from the client to the access point. Currently, most Wi-Fi air technologies only provide downstream enhancement. 5. uplink and downlink speeds The only widely accepted rate is the transmission rate. However, the asymmetric rate is typic

technologies only provide downstream enhancement. 5) Tx rate to Rx Rate The only widely accepted rate is the transmission rate. However, the asymmetric rate is typical, And the sending rate seen on our connectable client does not necessarily represent the receiving rate. This is also evidenced in access point/infrastructure because it proves that there is a separate Tx rate and Rx rate in the Wi-Fi world. 6) Same sending power for all rates Setting an access point to the "maximum power" does no
