Wi-Fi LAN Settings On Windows 7 Laptops
Automatic switching between 40MHz and 20MHz is called auto 20/40MHZ. The new 802.11n radio can use either a 20MHz or a 40MHz channel.
Multi-Band vs. Dual-Band Access Points
Multi-band Access Points (APs) are typically ideal for small businesses that require future flexibility to change the frequency band. Dual-Band APs are ideal in larger enterprise organizations.
Q: Why do I need to redo my radio frequency (RF) plan when I upgrade from 802.11b/g to 802.11n?
Newer Wi-Fi systems achieve higher data rates primarily through new antenna techniques called multi-input multi-output (MIMO). Redoing your radio frequency will avoid interference and degradation in performance.
Q: There's an area in my building that has a weak wireless signal. Should I place an Access Point in there to cover that spot?
Deploying additional APs where Wi-Fi signals are weak will give users higher data rates. Follow these basic rules for deploying additional APs.
Access Point Country Code Settings
Setting the correct country code ensures the AP spectrum and transmit powers are within the legal limits for your region of the world.
Q: What is 4G?
Wireless 4G technical definition is that it meets the International Telecommunications Union's (ITU's) IMT-advanced specifications including a data rate of 100 MBPS at low mobility pedestrian speed.
Wireless Network Channel Deployment
Configuring your wireless network so that adjacent Access Points (APs) are on non-overlapping channels gives you the best throughput and performance.
