Hi,can you please explain advantages and disadvantages of ROVER TECHNOLOGY?

Rover Technology adds a user's location to other dimensions of system awareness, such as time, user preferences, and client device capabilities. The software architecture of Rover systems is designed to scale to large user populations.
Consider a group visiting museums in Washington, D.C. The group arrives at a registration point, where each person receives a handheld device with audio, video and wireless communication capabilities. A PDA available in the market today. A wireless system tracks the location of these devices and presents relevant information about the objects displayed as the user moves through the museum. Users can consult their devices for maps and optimal routes to the objects of interest. They can also use the devices to book and purchase tickets for museum events later in the day. The group leader can send messages to coordinate the activities of the group. The part of this system that automatically adapts information and services to a mobile user's location is the basis for location-based computing. This computational paradigm increases the more traditional dimensions of system consciousness, such as time, user, and device. All technological components for performing location-based computing are available in the market today. What has hampered the widespread deployment of location-based systems is the lack of an integration architecture that balances with user populations. Rover tracks the location of system users and dynamically configures application-level information to different link layer technologies and client device capabilities. A Rover system represents a single administrative control domain, managed and moderated by a Rover controller. Figure 1 shows a large application domain divided into multiple administrative domains, each with its own Rover system, as well as the Internet domain name system. End users interact with the system through Rover's client devices, usually handheld wireless units with different processing, memory and storage capacities, graphics and display, and network interfaces. Rover maintains a profile for each device, identifying its capabilities and configuring the content accordingly. Rover also maintains end user profiles, defining specific user interests and offering content tailored to them. A wireless access infrastructure provides connectivity to Rover customers. In the current implementation, we have defined a technique to determine the location based on certain properties of the wireless access infrastructure. Although Rover can take advantage of such specific air interface properties, 1 its location management technique is not tied to a particular wireless technology. In addition, different wireless interfaces can coexist in a single Rover system or in different domains of a multi-Rover system. Software radio technology3 offers a way to integrate the different interfaces into a single device. This would allow the device to move easily between several Rover systems, each with different wireless access technologies. A server system implements and manages Rover end-user services. The server system consists of five components: The Rover controller is the "brain" of the system. It manages the different services that Rover clients request, program and filter the content according to the current location and the user and device profiles. The location server is a dedicated unit that manages client device location services within the Rover system. Alternatively, applications can use an externally available location service, such as the Global Positioning System (GPS). The streaming-media unit manages the audio and video content transmitted to customers. Many of the current media streaming units available on the market can be integrated with the Rover system. |
