Abstract

When talking about location-based services, one of the key factors influencing the overall service quality is the positioning accuracy that the system can rely upon. Nowadays, wireless LAN hardware supports the variation of the transmission power in a wide range. In this paper, two novel algorithms suitable for extension of common wireless LAN-based positioning systems are presented. These novel algorithms exploit the additional information that can be gained by using one or more non-standard transmission power levels. Our findings indicate that the overall positioning accuracy and reliability can be increased with such an approach.
