wireless access to your home’s Internet connection to download the latest

operating system software from Baldwin’s servers, too The system can

accept any wireless MIDI interface Encore!

You can record on this system, too A one-touch Quick-Record button

lets you instantly save piano performances, such as your child’s piano recital

You can also use songs that you record and store on floppy disk with your PC

to use within editing, sequencing, and score notation programs

Your Pets

GPS-based tracking services can be used for pets, too! Just about everyone

can identity with having lost their pet at some point The GPS device’s form

factor can be collar-based or a subdermal implant This can serve as your

pet’s electronic ID tag; it also can serve as the basis for real-time feedback to

the pet or its owner, perhaps providing automatic notification if your dog

goes out of the yard, for instance

Check out www.homeagainid.comto find out about an Applied Digital-driven

service for tracking your pet today What makes this interesting is making the

wireless connection more active than passive, adding 802.11 and GPS

tech-nologies so that there can be an ever-present signal to track your pet within

the service area Several companies are testing such capabilities so that

soon, your LAN may indeed be part of a neighborhood wireless network

infra-structure that provides a NAN — neighborhood area network — one of whose

benefits is such continual tracking capability

Your Phones

True, many phones in homes today are wireless (And, of course, cell phones

are, too.) But remember that your wireless home network uses the same 2.4

GHz and 5.8 GHz wireless frequencies that your cordless phones do And

when you factor in that your neighbor’s phones and a bunch of other devices

in home are also on these frequencies, the throughput and usability of your

wireless home networking system can get watered down pretty fast

Enter your whole home 802.11 network It makes sense to migrate your

cord-less phones, for instance, to your home wirecord-less network so that your wirecord-less

phones won’t compete and interfere with your home wireless network; instead,

you can get 802.11-based phones that ride over the same network in a very

seamless way (Chapter 2 has all the details about the 802.11 protocol.)

To do this, you will need to get an 802.11-enabled phone, which would workexactly like a cordless phone In fact, you scarcely could tell the differencebetween the two There are only a few such phones available today, and theyare fairly pricey, but soon, you’ll probably see a lot more home telephoneproducts that support 802.11 You might also see 802.11 technology bundledinside your cell phone as well, although the early moves with cellular havefocused on Bluetooth enablement, which we talk about in Chapter 15.

You can find 802.11b-based business phones today from Symbol Technologies(www.symbol.com) or SpectraLink (www.spectralink.com), but these aremore business class products and require business telephone gear and VoIP(Voice over IP) gateways to work We estimate that it will be a few yearsbefore these get to the price points that you’d pick one up at RadioShack orCompUSA Expect to see your cell phone sporting an 802.11b/VoIP capabilitysometime in the next few years, too

You can still use your wireless network and broadband connection to makelow-cost phone calls With a Cisco (www.cisco.com) ATA-186, which is a two-port analog telephone adapter that turns traditional analog phones into IPphones, you can place calls to any of a number of VoIP telephone companies(like www.vonage.com) that will carry your calls to their destination for lowrates (less than the traditional long distance carrier rates for sure) Unlimitedcalling services like Vonage (www.vonage.com) take your normal ordinaryphones and connect them to a special device, like the Cisco ATA-186, thatallows you to place phone calls over IP networks, like your home wirelessLAN and the Internet

Just plug your cordless phone into the Cisco adapter and call away You canalso make calls over your laptop with software from companies like

Net2Phone (www.net2phone.com); Net2Phone also has a strong line-up ofhardware for VoIP calling

Although the ATA-186 is not wireless itself yet, we expect it (or a similar model)

to be so shortly In the meantime, if you need to, you can get your ATA-186 ontoyour wireless network with a wireless bridge, such as the D-Link DWL-810+(www.d-link.com), which we use with gaming devices in Chapter 12

Your Robots

Current technology dictates that robots are reliant on special algorithms andhidden technologies to help them navigate For instance, the $199 Roombarobotic vacuum cleaner from iRobot (www.irobot.com) relies on internalprogramming and virtual walls to contain its coverage area The $499

Friendly Machines Robomow (www.friendlymachines.com) robotic

lawn-mower relies on hidden wiring under the ground

As your home becomes more wireless, devices can start to triangulate their

position based on home-based homing beacons, of sorts, that help them

sense their position at any time The presence of a wireless home network

will drive new innovation into these devices Most manufacturers are busy

designing 802.11 into the next versions of their products

The following list highlights some other product ideas that manufacturers are

working on now We can’t yet offer price points or tell you when these

prod-ucts will hit the market, but expect them to come soon

 Robotic garbage taker-outers: Robotic firms are designing units that

will take the trash out for you, on schedule, no matter what the weather

Simple as that

 Robotic mail collectors: A robotic mail collector will go get the mail for

you Neither snow, nor rain, nor gloom of night, nor winds of change, nor

a nation challenged will stay them from the swift completion of their

appointed rounds New wirelessly outfitted mailboxes will tell you (and

the robots) when the mail has arrived

 Robotic snow blowers: Manufacturers are working to perfect robotic

snow blowers that continually clear your driveway and sidewalks while

snow falls

 Robotic golf ball retrievers: These bots retrieve golf balls Initially being

designed for driving range use, they are being modified for the home

market

 Robotic guard dogs: Companies such as iRobot (www.irobot.com) sell

CoWorkers, which are robots that can roam areas and send back audio

and video feeds

 Robotic gutter cleaners: A range of spider-like robots are available that

can maneuver on inclines, like a roof, and feature robotic sensors and

arms that can clean areas

 Robotic cooks: Put the ingredients in, select a mode, and wait for your

dinner to be cooked — better than a TV dinner for sure

 Robotic pooper-scoopers: The units that we’ve discovered roam your

yard in search of something to clean up and then deposit the findings in

a place that you determine

You’re more likely to see humanoid robots at special events demonstrating

stuff than in your kitchen cooking dinner Products such as Honda’s ASIMO

(Advanced Step in Innovative Mobility, world.honda.com/ASIMO/) are

remarkable for the basic things they can do, like shake hands and bow, but

the taskmasters that we mention above are really going to help you with

day-to-day chores

Your Wearing Apparel

Wireless is also making its way into your clothing Researchers are already

experimenting with so-called wearables — the merging of 802.11 and

Bluetooth directly into clothing so that it can have networking capabilities.Want to synch your PDA? No problem — just stick it in your pocket MIT Labs

has been showing off some clothing that looks more like a Borg from Star Trek than anything practical, but there are all sorts of companies working on

waterproof and washerproof devices for wirelessly connecting to your homewireless network

Wireless technology will also infiltrate your clothing through radio frequencyidentification tags, or RFIDs, which are very small, lightweight, electronicread/write storage devices (microchips) that are half the size of a grain ofsand They listen for a radio query and when pinged, respond back by trans-mitting their ID code Most RFID tags have no batteries because they use thepower from the initial radio signal to transmit their response; thus, theynever wear out Data is accessible in real time through handheld and/or fixed-position readers, using RF signals to transfer data to and from tags RFIDapplications are infinite, but when embedded in clothing, RFIDs will offerapplications such as tracking people (like kids at school) or sorting clothingfrom the dryer (no more problems matching socks or identifying clothes foreach child’s pile)

A technology of great impact in our lifetime is GPS, which is increasinglybeing built into cars, cell phones, devices, and clothing GPS equipment andchips are so cheap that you’re going to find them everywhere They are used

in amusement parks to help keep track of your kids Some shoe ers are talking about embedding chips in shoes

manufactur-Most GPS-driven applications have software that enables you to interpret theGPS results So you can grab a Web tablet at home while on your couch, wire-lessly surf to the tracking Web site, and determine where Fido (or Fred) islocated Want to see whether your wife’s car is heading home from work yet?Grab your PDA as you walk down the street, log onto a nearby hot spot, andcheck it out A lot of applications are also being ported to cell phones, so youalso can use those wireless devices to find out what’s going on

GPS-based devices — primarily in a watch form — are available that cantrack people The Wherify Watch, shown in Figure 19-2, is a great device thatallows you to track children and the elderly (such as Alzheimer’s patients)who might wander off The caretaker can then go to a Web site, view a mapshowing the wearer’s location, and easily find the wanderer

You can actually replay the signals received from the device over a period of

time — sort of like a Family Circus cartoon showing the path of the little kid

bopping around town Watches are pricey, running about $300–$400 apiece

plus monthly monitoring fees of $10–$50

Check out companies like Wherify (www.wherify.com) and Applied Digital

Solutions (www.digitalangel.net) for their products Applied Digital has

developed VeriChip (www.adsx.com/prodservpart/verichip.html) that

can be implanted under the skin for people in high-risk (think kidnapping)

areas overseas This chip is an implantable, 12 mm x 2.1 mm radio frequency

device, about the size of the point of a ballpoint pen It contains a unique

ver-ification number

Although watches are a great form factor for lots of wireless connectivity

opportunities, they have been hampered by either wired interface

require-ments (like a USB connection) or an infrared (IR) connection (which requires

line-of-sight to a specific on-ramp) Expect these same devices to very quickly

take on Bluetooth and 802.11 interfaces so that constant updating — like

with the Microsoft Smart Personal Objects Technology (SPOT) model

(www.microsoft.com/SPOT/) — can occur Watches are also popular for

Figure 19-2:

The Wherify

Watch

 Taking pictures: The Casio (www.casio.com) WQV10D-2 Color WristCamera watch with color liquid crystal display (LCD) lets you snap up to

100 images in JPEG format A 2X digital zoom enables you to get closer toyour subjects, and IR transfer enables you to share your pictures withother Casio wrist cameras and your PC An RF option is surely on the way

 Looking up phone numbers: The Casio BZX201SCR PC Unite Watch is

equipped with infrared capabilities, plus enhanced PC synchronizationfunctions In addition to being able to exchange personal informationmanager data with a computer, the PC Unite also can link with MicrosoftOutlook and even exchange data with a portable terminal such as a PDA.Creating wireless connectivity via jewelry bears its own set of issues because

of the size and weight requirements of the host jewelry for any wirelesssystem The smaller the jewelry, the less power that the wireless transmittercan have to do its job The less power, the shorter the range, and so the morelimited the bandwidth and application of the device

Shopping on CNET

Blogging for 802.11

Practically (wireless) networking

Surfing the vendor sites

We’ve tried hard in this book to capture all that’s happening with

wire-less networks in the home However, we can’t cover everything in onebook, and so, in fairness to other publications, we’re leaving some things forthem to talk about on their Web sites and in their print publications (Nice of

us, isn’t it?)

We want to keep you informed of the latest changes to what’s in this book So

we encourage you to check out the Wireless Home Networking For Dummies

update site at www.dummies.com/extras— where you can find updates andnew information

Here’s a listing of those publications that we read regularly (and thereforerecommend unabashedly) and which you should get your hands on as part ofyour home wireless networking project Many of these sources provide up-to-date performance information, which can be critical when making a decisionabout which equipment to buy and what standards to pursue

The Web sites mentioned also have a ton of information online, but you mighthave to try different search keywords to find what you’re looking for Some

publications like to use the term Wi-Fi, for instance, while others use 802.11.

If you don’t get hits on certain terms when you’re searching around, try otherones that you know It’s rare to come up empty on a search about wirelessnetworking these days All sites listed here are free

CNET.com (www.cnet.com) is a simple-to-use, free Web site where you can doapples-to-apples comparisons of wireless equipment You can count on find-ing pictures of what you’re buying, editor ratings of the equipment, user rat-ings of the gear, reviews of most devices, and a listing of the places on theWeb where you can buy it all — along with the actual pricing What’s greatabout CNET is that it covers the wireless networking aspect of Wi-Fi as well

as the consumer goods portion of Wi-Fi (such as home theater, A/V gear,phones, and so on) You can count on being able to find all sorts of productsand ideas in one place It’s your one-stop resource for evaluating your futurehome wireless purchases

What we especially like is the ability to do a side-by-side comparison so that

we can see who’s got which features You can go to the Wi-Fi portion of thesite and see available gear from major manufacturers By clicking the boxesnext to each name, you can select that gear for comparison shopping Youcan also filter the results by price, features, support, and so on at the bottom

of the page Then just click Compare to receive a results page

Overall, this is a solid site that we often visit before buying anything
