The 2.4 GHz Spectrum Congestion Problem and AP Form-Factors
2.4 GHz is a junk band...
2.4 GHz is interference ridden...
2.4 GHz is dead...
You've heard all of these dire warnings about microwaves, bluetooth accessories, cordless phones, baby monitors, lions and tigers and bears (oh my!), which will wreak havoc on your WLAN.
Well, I'm here to tell you that 2.4 GHz issues are self-inflicted. Any by self-inflicted I mean that Wi-Fi is the root cause of your Wi-Fi not working well. And specifically your own Wi-Fi. Poorly designed networks with too many APs blasting out too many signals all stomping on one another.
I'm a stickler for proper design, and is a mantra that I've probably beaten to death by this point. One aspect of proper design is deploying the proper number of radios to meet capacity needs. It's something that I talk about in my presentations on this subject and tweet about as well. Too many radios actually degrades performance due to the negative effects of co-channel interference and airtime utilization on a shared channel. More is decidedly NOT better!
Most WLAN designs today require a significant amount of
2.4 GHz radios to be disabled.
Most WLAN designs today require Continue reading
