Wi-Fi to Overtake Wired Network Traffic

Wi-Fi to Overtake Wired Network Traffic by 2015

Wired network traffic is still growing at a steady 26%, doubling every 3 years. But wireless traffic is forecast to continue growing at 36%, doubling in just over 2 years - over and over and over.

We forecast traffic as a way to ensure that guest expectations are met without unexpected upgrade requirements - and we know that guests given a choice between wired and wireless connections will choose wireless 3 to 4 times as often as a wired connection. That makes investments to retro-fit hotels with Ethernet an impossible ROI propisition because the cost is so high and the use so low.

But with wireless traffic outpacing Internet use in general, we'll need to rework that year-over-year expectation. We've already seen properties where fewer than half the devices on the network were Windows and MAC laptops - and the growth in tablets, WiFi phones, gaming consoles on the road and other devices will soon make laptops a permanent minority. Nearly all of those non-laptop devices have WiFi and NO wired ports.

We long ago gave up handling coverage as the primary issue for wireless - capacity is the real key. Even with .11n, if you put in fewer than 1 Access Point for every 12 active users you are going to get complaints (24 per dual-radio AP of course). How many rooms do you have? That number divided by 8 is the number of wireless Access Points you need - any fewer and you are just waiting for the complaints to start.

Are you ready to double the capacity of your in-house network and your Internet connection every 2 years?
