This was a manufacturing organization. They needed to use large number of wireless devices such as handheld scanners, wireless tablets, laptops etc. However the existing wireless network was unstable and resulted in frequent disconnections. Application used for entering data through wireless devices was not usable. Data entry had to be done through wired connections resulting in reduced efficiency with less productivity.
Approach / methodology
Our approach was to understand the environment through site inspection and perform a wireless site survey by measuring Wi-Fi and interference signal strengths in both frequency bands. We used the test results to find signal to noise ratio and draw the Wi-Fi heat maps to visualize the areas where there are high signal attenuation and dead spots for each frequency band. We were able to find multiple issues.
e used wireless networking tools to analyze the data and predict the optimal number of Wireless access points, best channels to use and the best location for each access point. We deployed a Cisco wireless controller based solution to provide the required Wi-Fi signal coverage. After deploying the wireless access points in the predicted locations we redid the site survey to validate the deployment.
- Achieved excellent Wi-Fi signal coverage for the entire area where the wireless devices were deployed in both 2.4 GHz and 5GHz bands.
- Increased wireless connectivity speeds improved efficiency.
- Increased productivity due to seemless operation of wireless devices.
