The tag is a relatively simple device that’s capable of sending data to another device. The reading distance of RFID varies from a few centimeters (passive tags) to severa l hundred meters (active tags). 3). A common application is in logistics or for automated toll payment on motorways. The key advantage of RFID over GPS is that the tag doesn’t require a power source nor does RFID require line of sight. RFID chips in or attached to mobi le phones can be used to send data (for example, NTT DOCOMO in Ja pan deployed the technology to allow subscribers to use the mobile phone as a door key) but not to detect absolute location.
In future commercial LBS applications, a mobile equipped with an RFID chip is likely to be included as part of hybrid location services to be able to locate mobile assets in a wide range of circumstances. 3 RFID chips come in all shapes and sizes, including implantable chips that mobile phone, rather than a separate (and can be used in the healthcare industry to diagnose disease, for example. more costly) tracking device. org. 3 CHAPTER 1 Location-based services: an overview Emergency response services The power of mobil e phones to commun icate in emergency situations with precise information as to the whereabouts of that emergency can turn them into indispensable tools for emergency assistance and rescue services, for example, when a child goes missing, an elderly relative is alone, or a university student is abducted.
This brought the possibility of mobile operators turning into mere data carriers (or dumb pipes, as seen with internet service providers) one step closer. The fact that Google later w ithdrew the direct sale of the N exus One (in July 2010), and ultimately all sales of this model, is more an indication of its failure to marke t the phone than failure of the direct sales model itself. 5 Google’s Nexus One smartphone, launched in January 2010 and featuring the latest version of the Android operating system, marked Google’s attempt to gain greater control of the mobile ecosystem.
