Non-critical medical equipment manufacturers are looking for alternative ways of collecting data as IT departments in hospitals will not provide access to their local network. Weightless could solve this problem with a low-cost alternative, a new wireless architecture with long-range capabilities indoors. This paper presents experimental data on the use of the Weightless Protocol inside buildings. Our results have shown that walls and floors are important obstacles and have more impact on the range limitations than distance. Actual coverage with Weightless is better than expected for all test locations.
