The TRENDnet TEW-653AP is a pretty neat product. It is a small easily concealable access point that can be pushed out to an area that has no power outlets using PoE. It has some excellent features and allows for great flexibility.
Unfortunately its signal penetration is very poor and makes it suitable for only single room usage. Our testing showed that once the signal passes through any type of wall, you lose a good deal of performance. However, the TEW-653AP has good "unobstructed" range. Even out to 50-feet we were getting 40MB/s over wireless N with WPA-2 AES. This made me think about where the TEW-653AP would really fit into a wireless network.
In the end I feel that the TEW-653AP is best suited to single point applications. This would be extending a wireless network out to a single room, or providing coverage in a large conference room. It is not intended for use to cover an entire home or office, but to extend the coverage of an existing network using WDS.
It is an excellent choice to provide "guest" style wireless coverage in a conference room or waiting area using the VLAN tags available in the WebUI. In this capacity it provides amazing speed and stability. At $108.19 from NewEgg.com this is a great product at a very good price. For me the TEW-653AP will go into the ceiling of the new testing lab to provide it with a good solid wireless connection point with a single cable instead of cluttering up any more desktop area.
For many the TEW-653AP will not be very exciting or interesting. However, if you are looking to extend your wireless, or provide wireless access to a single point without needing to worry about "how to get power out there", then the TRENDnet TEW-653AP could be an excellent choice for you.
