where art thou, wifi?


We plan on putting the wifi in the pantry at that red dot down below. From this location runs all the cable-cable and CAT 5e network cable. But I've been worried that the signal may not be strong enough to reach the master bedroom and the nether reaches of the living room. It seems like wifis generally reach the 40-foot range, but stuff in-between (walls, wires, toilets, fancy faucets, tile, cans of ravioli) will decrease that range (each circle below is at a 10-foot increment away from wifi central). At one point, I thought about building an extension out of the pantry along the ceiling into the hallway with screens on the sides such that we could put the wifi station there to extend its range. Nobody liked that idea.


Last night I'm surfing the cost of security camera systems and come across something called a "wireless access point". In short, it's a wifi placed where you want it in the house on a wall or ceiling as long as you have network cable there. In other words, you decide where you want it, and you install it there.

These critters are powered and work their wifi magic over CAT 5e. So instead of installing the wifi at the red dot, we can install it at the orange dot (and another one upstairs if we so choose). The one I stumbled upon was not cheap ($300 + another 100 to 200 bucks for power supplies and network boxes). But I found a cool one made by Ubiquiti called UniFi, and it's only $70: that's cooler than rabid rabbits rapidly riveting robots!





On the down side, it looks like I have more wiring to do this weekend... Fortunately I bought a bajillion feet of CAT 5e (and have only used half a bajillion).

home automation

Because I'm something of a gadget freak, my pals ask me about how automated our house will be. And I've disappointed them by noting that, aside from the audio system, we aren't planning to have any wired-in automation. Why? Three reasons, really: (1) cost, (2) rabid obsolescence, and (3) the coming revolution in wireless.

cost
Automation systems are expensive. We've checked out a few (for example, Control4), and they cost thousands and thousands of dollars. Furthermore, these systems are often proprietary. If you want an addition to your system or an upgrade, you have to have the local supplier supply and install it.  In other words, it's a bill that keeps on billing.

rabid obsolescence
Ever been in a house from the seventies with a pushbutton intercom? At least back then it took a decade or more for that system to become obsolete. In today's day and age, it can take a year. Many automation systems have their own (proprietary) touch screens and controllers. But how long before they become obsolete? And why have a proprietary touchscreen when many of us already have one in our pocket?

the coming revolution
Enter the reason we are holding off: Wireless. Most homes already exist; therefore, it's expensive to wire existing homes. This creates a strong incentive to develop a wireless solution to access the full home market.

the revolution arrived yesterday!
And just yesterday, Philips announced Hue, a wireless-controlled scalable lighting system:


The app-controlled system allows you to manage up to 60 LED bulbs (gulp) from the screen of your smart phone or tablet. You can change color and brightness and can even program special scenes such as fading on in the morning and flashing when you need to go to work. It's not exactly cheap ($200 for a wifi controller and 3 bulbs; $60 per bulb for extra bulbs), but it's less expensive than a wired proprietary system, it's user controlled, and it's infinitely flexible (need that light over there to be controlled rather than this one? Just change a bulb!). Geek.com has a nice detailed review of the technology. The starter package and extra bulbs will initially be sold at Apple stores.

Add this to the nest wifi controlled smart-thermostat, the beginnings of wifi controlled plugs, and (ugly) wifi door locks, and (reasonably) affordable home automation appears to be in reach.

competition coming
I've been following the Kickstarter efforts of LIFX to do the same thing. It has to be a blow to have one of the big boys beat you to market, but perhaps competition will drive prices lower (sweet note from one of the execs at Philips on LIFX's facebook page). Insteon has also had it's system out there for a bit.

house hackers?
All this wireless tech makes me wonder: Will the evolution of a hackglar (hacker plus burglar) be too far away?
