![]() An extensive measurement campaign with varying system configurations was arranged in different indoor environments. The capabilities of an outdoor-to-indoor analog WCDMA repeater are set against a dedicated indoor system and, furthermore, compared to indoor coverage of a nearby macrocellular base station. The paper provides practical information for enhancing the performance of high-speed downlink packet access (HSDPA) in an indoor environment. The target of the paper is to provide guidelines for indoor planning and optimization using an outdoor-to-indoor repeater or a dedicated indoor system. Finally, the HSDPA performance increase was limited by the noise rise in the uplink direction. However in corridor environment, clearly lower signal strengths were measured to be enough providing the high throughput when compar-ing with the open area environment. An average through-put of 3 Mbps was measured in both the open area and the corridor, when repeater was used. However, the suffi-cient average signal level has been measured to be different between the two measured location. The results indicate that high average downlink through-put can be achieved by using repeater if the received signal strength is raised to an adequate level. Two dif-ferent locations were measured: open area and corridor. Measurements were performed indoors in a typical office building in Finland. The ra-dio signal is captured from outdoor macrocellular network and guided to indoor distributed antenna system through an amplifying repeater. This paper presents how HSDPA performance can be im-proved indoors by using radio frequency repeaters.
