Wi-Fi is the most ubiquitous wireless connectivity technology today. After becoming a standard feature in all laptops, smartphones and tablets, Wi-Fi is being added to simpler products like home appliances, thermostats and many other home and building automation products that are feeding the exploding Internet of Things (IoT). Provisioning IoT products, that do not have a keyboard and display as a user interface, in a simple and robust way is a significant challenge. This paper reviews the main Wi-Fi provisioning methods available in the market and provides guidelines for choosing the right provisioning method for your product.

11. As the Wilson Amplifier recommends, channel holding uses two 20mhz channels to make a 40mhz channel, hypothetically multiplying the velocity. The issue is that utilizing 40mhz channels decreases the quantity of non-covering channels to only two. Thusly, this implies that impedance with your neighbors' Wi-Fi gear is substantially more probable, prompting poor exchange speeds and the likelihood of the association dropping out and out. Hence every one of the 802.11n switches ship with channel holding incapacitated of course. Unless you live in a remote territory, utilizing 40mhz groups on 2.4ghz is not suggested. http://www.wilsonamplifiers.com/
