The implications of switches from Wi-Fi to cellular data for commercial entities
In a world where connectivity is paramount, a shift has been observed in the way data is being consumed. This change, according to Eldar Tuvey from Wandera, is largely due to the increased data usage resulting from the automatic activation of Wi-Fi Assist in locations where corporate Wi-Fi was available.
The launch of iOS9 introduced Wi-Fi Assist, a feature that automatically connects devices to cellular networks when Wi-Fi signal is low or lost. This seemingly convenient feature has led to an unforeseen consequence: carrier plans are being eaten into faster due to increased data usage.
Users often find themselves relying on cellular data due to issues with Wi-Fi hotspots, such as spotty coverage, captive portal redirection, and security concerns. This reliance, coupled with the automatic switch to cellular networks, can result in the user being unaware of the increased data usage and potential overage costs.
The sunk cost for infrastructure in office buildings and airports makes upgrading Wi-Fi networks difficult. Wi-Fi devices still support 802.11 standards from as early as 1997, and upgrades to the Wi-Fi ecosystem require upgrades to devices and access points. However, adoption of these upgrades has been slow.
Cisco predicts that between 2014 and 2019, smartphone devices will be using almost five times more cellular data due to faster networks, busier apps, and less Wi-Fi usage. This prediction underscores the need for CIOs to grasp hold of the data being consumed and control unnecessary data-consuming activities with policies and caps.
Employees, in their quest for better connection, may find themselves opting for 3G and 4G over many Wi-Fi options. However, the bandwidth race for consumers has concluded, with current connectivity speeds surpassing the needs of apps and devices. 4G networks provide huge bandwidth, easily surpassing those of most Wi-Fi hotspots.
Despite the advances in 4G networks, Wi-Fi networks still have their own security vulnerabilities. Wigle.net shows a surprising number of open and WEP-protected networks that can easily be hacked. This article also suggests a related read titled "What does your Wi-Fi say about your employees?"
Companies like Aruba and Netgear have noticed slow adoption of new Wi-Fi standards in recent years. Aruba introduced Wi-Fi 6E products around 2021, and Netgear also released Wi-Fi 6E devices in early 2022. The slow adoption of these new standards highlights the challenges faced in upgrading Wi-Fi networks to meet the growing demands of data usage.
In conclusion, the shift towards increased cellular data usage is a complex issue, driven by a combination of factors including the automatic activation of Wi-Fi Assist, the slow adoption of new Wi-Fi standards, and the security vulnerabilities of Wi-Fi networks. CIOs must navigate these challenges to ensure they are controlling unnecessary data consumption and providing the best possible connectivity for their employees.
