Powerline vs Wi-Fi

Just about everyone knows what Wi-Fi is and most people even have it at home.  Because wireless N is not yet standardized, most people are still using wireless G.  What most people don’t know is that there is an alternative that in many cases will work better than wireless G and it uses lines you already have in your walls.

Powerline

Powerline connections use your existing electrical wiring.  One huge advantage is the simplicity.  Plug one powerline box into your router with an ethernet cable and the power cord into an electrical socket.  Then put your other powerline box wherever you need ethernet and hook it up to your device with an ethernet cable.  That’s it.  You’ve got internet.  Because of the simplicity, companies like Sling Media sell powerline devices like the Slinglink Turbo Powerline Kit to make hooking up a Slingbox that much easier.

Speed

A big problem with wireless is that you never actually get the claimed speeds.  Wireless G claims a theoretical max of 54Mbps.  Cut that number in half if you have two wireless devices talking to each other. With expected interference, such as neighbor’s Wi-Fi, you can likely cut that number in half again.  In my experience, if you get 20Mbps from ethernet device to Wi-Fi device, that’s about typical.  If you’re trying to move some big data like an HD show from one tivo to another, then you’re going from Wi-Fi to Wi-Fi and only getting about 10Mbps.  This is painfully slow.

This is where powerline becomes very handy.  If you just move one of your TiVos to powerline instead of Wi-Fi, you don’t have to cut that speed in half.  Powerline can take some trial and error to setup but if you find the best plugs to use, you can expect to get near 20Mbps and some newer powerline technology claims even more.  The end result is you can double your TiVo transfer speeds because only 1 TiVo on Wi-Fi can use the full 20Mbps while 1 on powerline is also getting 20Mbps.

Placement

Finding the best places to put the powerline devices may be the hardest part.  If speed is not important, you can probably use just about any 2 plugs.  I have yet to see 2 plugs that didn’t work at least a little.  The closer they are physically on the wire, the better the performance should be so it helps to know how your electrical is ran in your house.  If you don’t know, trial and error is a must as well as bandwidth testing software such as Qcheck.

Excellent Alternative

Everyone has Wi-Fi but that creates even more interference that slows it down. Powerline is a great alternative or complement to help maximize your home networking. Once wireless N is standardized, it will be much faster than wireless G but it will never be as simple to setup as powerline.

HD Radio in Washington D.C.

What is HD Radio?

Unfortunately, HD Radio has a misleading name. The letters “HD” stand for nothing. They only mean that it is digital instead of to analog. Digital does not mean that it is higher definition or higher quality than analog. It does mean that radio stations can fit more channels on the same spectrum.

What does HD Radio give you?

The Washington D.C. metro area has some great HD Radio stations. HD Radio gives you free extra channels to listen to outside of what is available on a normal AM/FM radio. Every channel listed below with a -2 or -3 is an extra channel that is not offered in analog AM or FM.

How to get HD Radio?

HD Radio’s Wikipedia page lists several HD Radio receivers for your car and home.

One of my favorites is the Sony XDR-F1HD. This costs about $100 and needs to be connected to an amp/receiver. It can not be connected directly to speakers unless they are powered speakers that can be connected with RCA cables.

If you need a new amp/receiver, there are some that have HD Radio built-in. My favorite of these is the Yamaha RX-V863, which can be ordered for $619 currently with a little haggling.

Is HD Radio worth it?

HD Radio has been around since 2002 and has been somewhat slow to take off. But if you like the extra stations it gives you, it can be worth the cost of the new equipment. Unlike Sirius and XM, there is no subscription to get HD Radio.

Washington D.C. offers more HD stations than most markets. The extra stations cover many genres and niches such as News, Bluegrass, Alternative, Country, Oldies, Jazz, and Gospel. If any of those stations interest you, give HD Radio a try.

Digital TV Converter Box Scams

The FCC has ordered all local over-the-air broadcasts be digital by February 17, 2009. Taking advantage of this, scammers are putting up ads and commercials claiming to offer free digital converter boxes. The FTC should shut down these misleading ads. One ad says:

The United States Deptartment of Commerce is preparing everyone for the switch to digital television by authorizing payment coupons for certified brands of these special TV boxes.

But the government process has us all tied up.

That’s why Universal TechTronics is providing these Miracle ClearView TV boxes immediately to the general public for free for everyone who gets the 5yr. warranty.

There are two problems with this. First, the device is only “free” if you don’t consider the mandatory warranty and shipping of $100.

But the main reason this is bogus is that most Americans don’t need to do anything. If you have satellite or cable TV, you are not affected. And if you are one of the rare Americans that uses a rabbit-ear antenna for over-the-air broadcasts, your TV could have a digital tuner built-in if it was purchased recently.

If you do need a digital converter box, it should cost about $60. You can get a $40 coupon from the federal government that lowers your cost to around $20.
