WiFi Roaming
Wi-Fi roaming is similar to cell phone roaming. To take advantage of WiFi roaming, your network must have multiple overlapping access points (APs) to ensure that you will always be within range of a different AP. Those overlapping access points can look like an Olympic ring, with APs in the center.
To make WiFi roaming work, all overlapping APs should have the same SSID, login credentials, and should automatically switch to the appropriate AP.
Wi-Fi Calling improves call quality while indoors
With more people spending time in places where cell phone signals are poor, WiFi roaming solution is a cost-effective solution for improving call quality while indoors. Wi-Fi Calling improves call quality when you're indoors, like in basements and car parking lots.
It automatically switches to Wi-Fi Calling when the cellular signal is weak or nonexistent. Moreover, it helps you make and receive calls even in places with limited or no cellular coverage.
Wi-Fi calling improves call quality when you're indoors, such as buildings that have spotty reception or residential countryside with poor carrier coverage. If you're a business owner, you can benefit from Wi-Fi calling.
IQsim enables business users to make and receive Wi-Fi calls without a cellular connection or a SIM card. IQsim offers a variety of rate plans, including flat-fee voice, allowing business users to avoid international rates.
WiFi calling may not be the best option for you, but it can save battery life in areas with poor cellular reception. If you're on a limited data plan and don't have access to Wi-Fi, it may be worthwhile to use WiFi calling instead.
Also, it can be helpful when you're traveling abroad, in areas where cell phone reception is poor, or when your phone's battery is running out of juice.
Handover process for WiFi roaming
WiFi roaming works similar to cell phone roaming in that it requires multiple access points in a building. Once the user's device gets close to the outer boundary of one access point, it can roam to another AP. The other access points must use the same SSID and login credentials. This process is known as handover.
This article will cover the basic steps required to implement WiFi roaming. In addition, we'll discuss how to implement WiFi roaming in your business.
The Handover process for WiFi roaming involves authenticating the new AP and associating with it. This process is simplified when the new AP has the same SSID as the target one. On the other hand, when the target AP has a different SSID, this process becomes more complex.
In either case, the number of authentication steps increases the risk of the connection being dropped. Several variables can affect the process, but ultimately, it is up to the STA to decide which route to take.
Cellular networks use different handover protocols than WiFi roaming. These networks implement various handover protocols, which may be either network-controlled or mobile-station-controlled, depending on the implementation.
Most modern cellular networks use a decentralized handover process and define key enhancements to ensure connection reliability. A key enhancement to this process is soft-handover, which allows the mobile station to establish a connection with the target cell before breaking the connection with the source cell. The purpose of this feature is to minimize the risk of service interruptions.
Environmental factors affecting WiFi roaming
Wireless coverage is impacted by a variety of environmental factors. Poor placement of customer premises equipment, adjacent channel interference, and the layout of a home can all interfere with wireless signals.
Too many legacy devices operating in the 2.4 GHz band can also cause dead zones in a WiFi network. A good reference can help troubleshoot issues when roaming. Listed below are some of the environmental factors that affect WiFi coverage.
