The presentation considers several areas, including:Is the BYOD trend Fad or Future? Stories of mass adoption from schools to universities around the world point to a new way of teaching and learning. But is it transformational?There are many challenges associated with BYOD and for many, the perception is ‘just add wireless to the wired network’. We’ll look at what else is involved for supporting a successful deployment.Turning to the Digital class room, we’ll look at the solutions areas that NETGEAR can bring to your organisation across the areas of switching, wireless, security and storage to support a robust and secure mobile environment.Finally, steps to success – we’ll look at where you are in the adoption cycle of BYOD. NETGEAR has a range of services to help you at whatever stage you are at in your project.
Erklärung von BYOD
Let’s start with recent independentContext research notes. PC sales are down 17% yoy for Q113. (Data based on desktops, notebooks and netbooks using Windows Home OS), whereas Tablets have tripled in the same period.Consider that Tablets are at times less expensive than PC’s helping to drive increased adoption, and in turn bringing down acquisition costs for both businesses, public sector organisations and education entities.ASP of €283: Down €100 in 12 months2-3 tablets for the price of a PC!
It’s clear that the adoption of technology in education has been considerable in recent times. With Tablet computing, there is a clear shift taking shape as technology splinters and becomes all pervasive across the school or university campus. Supporting and managing the divers array of IT means making the right choices. For some, diving into the deep end is the preferred way, for others, it’s a step by step process as we will see on the next slide.
Looking at the growth of wireless as a market, this recent Infonetics research highlights that wireless is growing at 3 times that of wired networking. This equates to ~10% CAGR. Latest generation wireless networking technologies like 802.11n are driving the rise in adoption.
Embracing BYOD has its pros and cons…..let’s explore these at a high level.
More importantly. To embrace BYOD, it is more than just adding wireless to the network. it’s not simply a case of supporting new smart phones or tablets for every pupil and staff member and leveraging a new way to learn with an abundance of new applications. If you’re increasing support for new devices, there are implications on providing a secure network environment for all users, from guests to students and staff and to mitigate against unwanted and unauthorised network access. So you need to look at defence in depth, including application security. For example, do you allow online access to Facebook? If you do, do you allow access to online gaming within Facebook or not? The coming together of technologies, or convergence of voice, video and data on one device has implications on the performance of your network. Tablet’s provide a single portal to deliver a multitude of communication capabilities allowing unprecedented levels of data production and consumption. It’s said that data is doubling every 2 years. In short, new devices means more users connecting to the network, 24 x7. Security remains a top concern and data protection compliance requirements must be met. More devices can equate to more users. This increases the load on the network. Where half a meg was once considered super broadband, it’s now surpassed by 80MB networks. Your switching infrastucture, the plumbing that allows data to travel across your network is potentially facing bottle necks where speeds of 100MB are no longer considered adequate for video streaming needs. Deploying Gigabit and 10Gigabit networks now become part of the conversation. And so the ‘knock on effect’ or ‘chain of events’ cycle continues.BYOD or tablet adoption is here to stay, but it’s critical that it is not seen in isolation from the network. It’s vital that it’s adoption considers the sum of the parts of the network and that each component can live up to expectations for today as well as tomorrow.
Even if you have decided BYOD is right for you, is it simply a case of adding a wireless network if you don’t already have one?
One hurdle is expense. For many, the vision is there, but the budget is not. Turning this around, we believe there is ample opportunity for education groups to undertake cost benefit analysis projects. For many existing adopters of Mobile computing, the ability to save paper costs alone have helped to provide an investment vehicle for adopting tablets.
This illustration is looks at the advantages of moving to a e-textbooks versus printed books. Besides the cost savings, other benefits can be realised as described.Consider also that tablets prices have dropped meaning that you can pick up 2 or 3 Android based devices for the price of 1 PC!
We saw Apps was a key word in the previous cloud. Transformational learning will come from applications and apps. First is the application of tablets – how they are used and where they are used. Then come the apps….iTunes saw the 1 billionth download in feb 2013…and there are thousands of education based apps available.Also, for some markets, the Raspberry Pi is making a big wave – by introducing basic computer science and programming. These devices can be connected by wire or wirelessly. Add these to tablets and you soon have a busy wireless network…..and this takes us to the concerns. Is the effort worth the gain?
Whether inside or outside a building, NETGEAR offers a number of solutions to support a digital class environment. Solutions include:CCTV SurveillanceWireless Networking in the form of Access Points and Broadband RoutersSecure connectivity in the form of Application Firewalls to allow safe and secure access to the Internet.Storage solutions for managing, protecting and sharing of dataSwitching to support Voice, Video and Data traffic across the networkWireless Controllers to manage the wireless traffic from BYOD and other mobile devices
Again, NETGEAR’s experience in Education highlights several challenges that customer’s face when deploying a wireless network. Many subjects and questions need to be addressed. The three in purple are tope examples where we have seen customer trip up in their deployment. Firstly, if you source cheap laptops, you will potentially undermine device performance results. The cheaper the device, the more likely it will have older generation wireless technology thereby limiting your users ability to have a superior wireless experience. Range could also become an issue necessitating more Access Points to be unnecessarily deployed to provide coverage. Had newer, better quality laptops been sourced, fewer Access Points would have been needed.Laptop profiles are also key. If you have upwards of 30 learners all trying to connect to Youtube at once, the heavier the profile list, the more devices will struggle to connect and work seamlessly and quickly on the network.The staff / teacher training example cannot be under-estimated. Examples are abound where schools have invested in tablets only to realise they cannot connect them as they have NO wireless network. Even if they do, how technically literate are your teachers at being able to use Tablets themselves. You need to ensure staff can use the devices, otherwise they will be the first to shun their usage in lessons.
Looking at the Digital Class, this section highlights some of the NETGEAR solutions at play.
