Full security is difficult to achieve due to wifi connection being wireless in nature. It requires proper security authentication protocols and configurations. Even though many encryption techniques are taken by the wireless networks, Wifi is still vulnerable to hacking. Due to its wireless nature it has high chances of being hacked especially the Public Wifi networks. Range offered by a Wifi network is limited, typically around 100-150 feet. The bandwidth of the Wifi network gets weaker as you add more devices. But still Wi-fi is an advanced mode of connecting to the internet. It is one of the greatest success stories of the technology era, and a key to continued social and economic growth. The increase in Wi-Fi devices and dependence upon Wi-Fi has made it a necessity of everyday life.In addition to its well-known societal benefits, Wi-Fi provides significant benefits to economies worldwide.
