How wireless WAN can make SD-WAN more agile and resilient

Wireless WAN has begun to rise in availability and utility, and to improve in affordability. It brings wide-area connectivity to just about any physical space and can hit speeds far in excess of older single or multiple T1 links and DSL.

It has its challenges to be sure, and the biggest ones are centered on the business model. It is hard to get a WWAN connection priced the same way a wired connection is: paying for a given speed, with no arbitrary limit on how many bits can be transferred in a billing period.

So IT teams using WWAN are typically faced with two unpleasant options: a) either pay a flat rate but, when a threshold number of bytes is hit, face a sharp decrease in speed; or b) pay a per-gigabyte overage fee for usage past the threshold. Sometimes carriers want to push both options—decreased speed and pay-by-the-drink overage costs.
