I have been slowly making more and more of my time about mobile first. I now use my iPad Pro more than my MacBook Pro. It is way more convenient to have the iPad Pro than the MacBook Pro.
As part of focusing on Mobile I spend more time on 802.11. Latest is to improve me home office network. I have 5 access points running off one controller. Reading this post on the end of 2.4ghz
On February 3rd, 2016 Cisco released a joint statement (http://bit.ly/1T7Niet) with Apple thatannounced the death of the 2.4GHz spectrum. The 2.4GHz band, often referred as the Universal Band, was the primary spectrum leveraged when initial Wi-Fi standards were first introduced 17 years ago. Over the years, this spectrum has become jammed with traffic; it offers only 3 non-overlapping channels of which many devices and technologies make use.
2.4Ghz was the initial focal point for first to market Wi-Fi deployments. In 1999, the IEEE also created a Wi-Fi standard for operation in 5GHz which supports 24 non-overlapping channels with 8 times the capacity available in 2.4GHz.
What’s surprising about the Apple/Cisco announcement is the timing of this report. Cisco has been shipping access points (AP’s) for years with one fixed 2.4GHz radio and one fixed 5GHz radio. In contrast, for the past decade Xirrus has been shipping products with software programmable radios that enable customers to select 2.4GHz or 5GHz at the click of a mouse on any radio within an AP. (Xirrus is the only Wi-Fi company with a product line that offers a choice of 2-16 radios per AP with customizable spectrum per radio).This capability provides massive flexibility to customers and extends the lifetime of Xirrus customer Wi-Fi products up to 10 years. Not surprisingly, within 2 weeks of the release of this document, Cisco finally announced new AP technology that supports a form of software programmability for 1 radio with their AP.
What does this all mean? Well, Cisco finally has admitted 5GHz-only networks are the way forward. Therefore, it’s challenging to expect a customer to purchase an AP with 2 radios where 50% needs to be turned off! The move to an all-5GHz AP is a logical step, albeit one 10 years after Xirrus first pioneered this Wi-Fi offering. The real question though, is why stop at 2 x 5GHz radios in an AP? Why not 3, 4 or more??
