Creating the Right Network Infrastructure for Tomorrow’s Digital Learners
Changes in how teachers use technology to reach students is causing network administrators to reconsider the way they think about network bandwidth, and these changes are speeding up hardware refresh cycles. Are you ready?
Two huge factors are driving these rapid changes in educational networking:
- The way that faculty members are using media to reach students
- The number of devices each student brings on campus
The changes will require network administrators to rethink their network bandwidth situation.
Teacher's and student's need for more network bandwidth is placing some institutions in a tricky spot, especially if wireless access points were just upgraded two or three years ago. However, the new upgrade is one that will meet school’s needs well into the future.
Video Drives the Network
Everyone wants their YouTube and cat videos. And in class, professors are not projecting video onto a central screen. They are giving students a URL to watch the video on their personal devices. The class is now responsible for 20 - 200 network streams instead of one.
That and students constantly checking for mail and social media updates mean a dramatic increase in the bandwidth required to each classroom, and to the campus as a whole.
New WiFi to the Rescue
The good news is that a new wireless networking standard, 802.11ac Wave 2 has now entered the field. 802.11n Wave 1, the highly successful predecessor to Wave 2, could provide bandwidth of more than 700 Mbps. Access points for 802.11ac Wave 2 can provide up to 7 gigabits per second of speed. It can also provide that high-speed access to some devices while providing lower speeds to older clients. The whole network does not slow down when old devices are present.
802.11ac Wave 2, which was certified by the WiFi Alliance and rolled out late 2016 solves many wireless issues but creates a need for a faster and more robust backbone. Current Technologies is partnered with Aruba Networks, Cisco Systems, and Aerohive Networks to customize a wireless access system using the most up-to-date technology that delivers superb WiFi performance.
New Wireless Means new Wires
Most campuses have gigabit ethernet supplying their access points. Obviously, 7-gigabit access points need more than one gigabit Ethernet, so some campuses have begun dropping 10-gigabit lines to their APs. Also, these faster APs require Power Over Ethernet+, which may involve new injectors or Ethernet switches. These are not small costs because they involve changing physical infrastructure in existing structures.
Moving to 802.11ac is not like the move from 802.11a to 802.11n. The new move is a significant upgrade to the infrastructure.
