Graphic: Comparing Wireless Technology Range and Data Rates

This graphic helps visualize the different use-cases for various wireless technologies by comparing range and data rates.

A few notes:

• LTE could be included in the same area as WiMax, and could probably be re-named "4G".
• Wi-Fi will soon approach Gigabit speeds with 802.11ac and 802.11ad and would shift upward in the graphic.

Cheers,
Andrew

802.11: Safety equipment for outdoor WLAN deployments: 

"Deploying outdoor network is hard. It is hard technology wise. One is bound by the limitations of the technology (the 802.11 standard), regulatory restrictions (FCC and the likes) and the environment itself (buildings, trees, hills, weather changes, etc). And once you have designed the network, you have to deploy the network."

How to Get Your Idea Approved - Amy Gallo - Best Practices - Harvard Business Review: 

"When you have an idea, proposal, or recommendation that you believe in, it's easy to presume that getting it approved will be a breeze. If you see how great the idea is, won't everyone else? However, whether an audience accepts an idea is often less about the idea itself than about how you present it. When you need approval, don't assume that just because it's brilliant, others will see it that way — convince them."
