`uLocate’s GPS-based service helps you keeptrack offamily
`and friends. BY ALANCOHEN
`
`ig Brother may not know your
`
`Be move, but your boss, your
`
`
`
`phonehandsets. Indeed, most new phones
`have them—evenif the networks they run
`on haveyetto activate them.
`A phoneusing uLocatelinks to the GPS
`satellites—at least three, but typically five
`or seven to get a fix within 100 feet of
`accurate—andcalculates its location,
`speed, and direction of movement. A Java
`applet running on the phonesendsthis
`data overthe cellular network, which,in
`turn, sends it to uLocate’s server in
`Waltham, Massachusetts. The server—a
`Dell PowerEdge 1750 with dual 2.8 GHz
`Xeon processors running Linux—uses
`MapQuest Enterprise Server to turn
`longitude andlatitude data into an address
`andplotit on a map, which can be viewed
`on a Web pageor a phone.
`To makethe location data more useful
`to its customers, uLocate has developed
`some enhancements.For instance, users
`can set up “geofences” aroundspecific
`locations; when a phoneentersor leaves
`thatarea, an alert is triggered. This could
`be used to let parents know, by e-mail or
`SMS, whena child reaches school.
`
` Location, Location,
`
`Location data is also stored—currently for 90 days—sousers can check some-
`
`driving directions to the nearest ATM.

`
`one’s route days or weeks later. “It comes
`in handy whena customer complains that
`something didn’t arrive on time,” says
`Frank Schroth, uLocate’s vice president of
`marketing. Indeed, uLocate’s business
`users tend to be companies withfield
`personnel. “They use it to check on
`deliveries, but also to cut down on the
`unauthorized useof vehicles and to ensure
`the safety of drivers,” says Schroth.
`Consumers, on the other hand, typically
`use the service to keep tabs on children or
`other family members.
`The system is not foolproof. For one
`thing, those being tracked canfoil uLocate
`simply by turning off their phones. When
`a cell signal is dropped,ulocate is dropped
`with it. And since the GPSreceiver in the
`handset needsa clearline ofsight to at
`least three of the GPSsatellites, the system
`won't work if the phoneis indoors, under-
`ground, or in a covered vehicle. In that
`case, the map will display only the phone’s
`last knownlocation.
`At press time, uLocate wasavailable
`for free (users, however, must purchase a
`wireless data plan from theircarrier), but
`Schroth expects it to go commercial this
`spring, with rates of approximately $8 to
`$9 per monthforthe first phone on the
`account and discounts for subsequent
`phones.
`uLocate plans enhancementsthat will
`maketheservicea little more inviting for
`those being tracked. For example, after
`plotting yourlocation, it could send you
`
`coworkers, and your spouse soon
`may. And they won't have to do much to
`find you, either. They'll go to a Web page
`for a map showing everywhere you've
`been all day—bad newsif you skipped
`workto go to the movies, good newsif
`you're stranded ontheside of a road.
`What gave you away? Your cell phone.
`Thanksto new location-based services,
`your phoneis not just a communications
`device,it’s a homing beacon.
`Oneof the first companies to launch a
`phone-basedtracking service is uLocate
`Communications,a year-old startup based
`in Newton, Massachusetts. It has in-
`tegrated the location technology being
`built into new cell phones with the Inter-
`net, creating private Web pages where cus-
`tomerscantrack the comings, goings, and
`(sometimes) unauthorized escapades of
`employeesand loved ones.
`Although uLocate (www.ulocate.com)
`| has launched on the Nextel network and
`is available to subscribers who have one
`of three Motorola handsets,the service is
`' very mucha workin progress. Some of
`the biggest wireless carriers, including
`Sprint PCS and Verizon,arestill upgrad-'
`ing their networks to enable location-
`basedservices. You can expect them to be
`location-aware soon, however, as federal
`E91 legislation mandates that
`they
`incorporate the technology into their
`networks so emergency response systems
`can locate any cellular handset.
`What makesservices like uLocate pos-
`sible is the Global Positioning System, a
`constellation of 24 satellites that circle the
`| Earth in synchronousorbits and continu-
`| ously transmitradiosignals to terrestrial
`receivers. By picking up the signals of
`three or moresatellites, a GPS receiver can |
`‘ calculate its own position on the ground.
`Today’s receivers can be miniaturized
`enoughto fit easily and economically into
