In supplying electrical power to an AP (either 1252 or 1140), does a power injector have any advantage over a local power supply -- other than the electrical outlet does not need to be nearby? Does the power injector have any disadvantages when compared to a local power supply?
The power injectors are just a little less cumbersome, they can inject power up to 300 feet. So if you are not sure where your access point will get the best coverage, it is hard to have outlets hardwired in 85 different locations as you test your AP in different spots.
However the injector allows you to do that.
As far as price is concerned, the injector is maybe $75 more than the supply.
