Analysis of indoor-indoor and satellite/HAP indoor propagation effects
11th International Conference on Antennas and Propagation (ICAP 2001), 2001Satellite and high altitude platforms (HAPs) are an important concept for next generation fixed and mobile communications. To predict indoor field strength levels from such distant transmitters, modifications to the standard indoor ray-tracing concept are proposed.

Proceedings of the 2014 ACM International Joint Conference on Pervasive and Ubiquitous Computing, 2014
Location prediction enables us to use a person's mobility history to realize various applications such as efficient temperature control, opportunistic meeting support, and automated receptionists. Indoor location prediction is a challenging problem, particularly due to a high density of possible locations and short transition distances between these ...

Penetration Loss at 60 GHz for Indoor-to-Indoor and Outdoor-to-Indoor Mobile Scenarios
2020 14th European Conference on Antennas and Propagation (EuCAP), 2020This paper investigates the penetration loss of an office building in indoor-to-indoor (I2I) and outdoor-to-indoor (O2I) mobile scenarios. The measurements were collected using our 60 GHz double-directional switched-antenna channel sounder. During measurements, the transmitter, mounted on a tripod, was placed in an office and outside of the building ...

The study of indoor microclimate requires a specific set of tools to measure the physical variables and interpret the results. This chapter, in its first part, describes how to study Historic Indoor Microclimate. In particular, the main physical variables, the standard values, and the methods to measure them are described.

Mass-market requirements for indoor positioning and indoor navigation
2010 International Conference on Indoor Positioning and Indoor Navigation, 2010The next step in location services will be repeating the success of location services in outdoor use for navigation and local search in the indoor environment. In order to make indoor positioning and navigation reality in large scale not only compelling business opportunities must be present, but also the technology must be low-cost, low-power, have ...

Museums are both appealing and challenging as an environment for indoor positioning research. By nature, they are dense and rich in objects and information, and as a result they contain more information than a visitor can absorb in a time-limited visit.

2013 Tenth International Conference on Wireless and Optical Communications Networks (WOCN), 2013
Setting up of any indoor localization system involves many difficulties. This paper proposes a Simple, Low cost & Small sized system for indoor localization. The basic processing elements of this system constitute RSSI & LQI (symbol error rate). An ISM band compliant low cost cc2500 zigbee module capable of outputting digital RSSI and LQI values is ...

This paper presents an experimental study of the propagation channel in Indoor environment with two radio link configurations: outdoor to indoor (O2I) and indoor to indoor (I2I). The experimentation has been carried out with a MIMO set-up which allows a full 3D space-time characterization of the channel.

Fast-converging indoor mapping for wireless indoor localization
2014 IEEE International Conference on Pervasive Computing and Communication Workshops (PERCOM WORKSHOPS), 2014The construction of indoor floor plans for wireless localization with minimal deployment effort and with low cost is relevant in many ambient intelligence and mobile computing applications. Simultaneous Localization and Mapping (SLAM) is a well-known technique for solving the problem of localization of an object in an unknown environment while ...
