Powerline Adapter Final Thoughts

The TRENDnet 200Mbps Powerline AV Adapter is a great alternative for those seeking to easily set up a network, and are unable or don't want to use ethernet cables or wireless adapters. Compared to ethernet, the speeds are slightly (roughly 2MB/S) slower. I was shocked; I was expecting the speed to be fairly unreliable, however this was not the case. Compared the wireless, the speeds were naturally much better.

I feel this technology is, althought being used prior to this, still in a relatively new stage. Until developers can begin to work out the various kinks involving the fluctuation of power lowering speeds, many users may disregard powerline networking in it's entirety. However, there have been many variations of powerline adapters, each with improved functionality than the previous (increased speed and security), so who knows what the future holds?

It may benefit us if companies like TRENDnet have more competition in the powerline networking market. It only seems that similar, name-brand networking companies like D-Link are offering powerline devices comparable to this. It'd be nice if this technology caught on and became mainstream, as we'd begin to see several other products offering specific features to suit our individual needs.

TRENDnet TPL-303E2K Conclusion

Performance of the Powerline AV Adapter kit was fairly comparable to the speeds of two computers connected via ethernet. However, it really depends on how you're electrical wiring is set up, as this can really impact the speed of your network.

The appearance of the adapters are very well done; they both look very modern and stylish. Both are almost entirely white. They look like something we'd see created by Apple.

They construction of the Powerline AV adapter kit was also well done. Both adapters seemed to bear a solid-yet-light plastic.

The functionality of the adapters is what you'd expect, as they do exactly what they say. The included software is very basic and simple to use.

TRENDnet TPL-303E2K adapter, although more expensive than a standard CAT-5e cable, costs much less than setting up a wireless network or wiring upgrades. The current price at NewEgg is $79.99, but there are several other online retailers that list this kit as well.

If you're able, use ethernet cabling instead, for that would be much more cost-effective. However, if you're unable to use that and are looking for fast speeds (as opposed to wireless), then pick up the TRENDnet AV Adapter Kit.

# Most impressive speedK Gregory 2010-08-15 12:49
Great review and testing methods. I really like the powerline product in every way. It can serve as an option for granting access to isolated areas or places that are difficult to wire.

I'm curious if 'conditioned' power would increase the throughput. Such as a basic line conditioner (Tripp Lite, Belkin, etc.) on both outlets and then the powerline product is connected to the line conditioner. Any interest in this setup and test for better throughput?

Power line conditioning is not something that occurs throught the entire circuit, only to devices behind the conditioned endpoint (UPS, etc).

# Correct, wasn't implying otherwiseK Gregory 2010-08-16 08:14
There simply must be associative performance with a product like the Trendnet PowerLine product and fluctuations on a circuit in many homes as your review touches on a bit. Thus the curiosity I have for some voltage regulation\power conditioning at the TX and RX points that may reflect better throughput and reliability. I can't comprehend that there wouldn't be any change if the noise is reduced or eliminated, and the many overvolts,undervolts and the like are addressed by a voltage regulator\power conditioner. Am I correct that you believe otherwise?

# Very InterestingJohn Darcy 2010-08-16 10:25
I was very interested by this article. I had heard about the technology but never seen a review or known of its use anywhere by anyone, or even discussed as an alternative to wireless impaired areas. I was happily elucidated this morning by this review.
As you pointed out, this can be a great addition to home and small business networking; the speed it what caught my attention.
I will be looking for this and might even give it a try early next year. I use wireless on a couple of my computers because i didnt want to drill through walls for the cat5 or cat 6 ethernet connections.
I enjoyed being enlightened and having my curiosity peeked as well by this review.

# 200 Mbps or 100 MbpsDigital.Ark 2010-09-30 09:43
What I don't get, is why this thing would be advertised as capable of up to 200 Mbps under ideal wiring conditions over short distances, but only supports up to 100 Mbps on it's Ethernet port. Wouldn't you need Gigabit Ethernet to support up to 200 Mbps?

Presumably, this thing is only capable of up to 100 Mbps theoretically, because of the bottleneck at the Ethernet port.

Am I missing something? Because the box clearly says 200 Mbps powerline, and 100 Mbps Ethernet on the specifications list.

# 100 Mbps Full duplexFinal Frontier 2010-10-06 03:06
Ever thought about full duplex on Fastethernet ? The marketing department makes it 2 x 100 Mbps = 200Mbps

# Great Alternative to WirelessKevin T 2011-05-19 13:49
Great review and testing method. This was exactly the information I was looking for before deciding to set up my network. Sounds like a great alternative to wireless although the speeds cannot compare to traditional ethernet.
