What users want, where they want it
GPS has made an enormously successful transition into automobile navigation markets. The technology holds even more promise as a peripheral function for handsets.
But, even though this target application is stimulated by regulatory demands, implementation problems have reduced its usefulness, and disappointed many early users. For success in consumer-grade handsets, users want location information on demand, and in the environments they use the phones in - which demands something that works indoors as well as the handset's voice communications.
If the new capability is to be accepted readily, positioning functionality needs to be introduced in the almost transparent way that previous major features have arrived:
- at very low cost
- with much the same kind of battery life as before
- without impacting the performance of existing phone features
eGPS delivers useful location information on demand, in any environment with handset coverage, without adding significant cost or impacting a handset's other functions. A range of implementation options allows handset developers and carriers to implement eGPS in optimised forms for all types of user and classes of handset.
