Measurements

Here we provide measurements obtained by the Rice Networks Group that characterize the TFA Network.

We characterize the coverage of the TFA Network by providing a set of results that describes the received signal strength from all surrounding APs, for every location of the TFA neighborhood. The methodology employs a wardriving process. In particular, we extract values for signal strength reception from beacons collected with the Netstumbler tool, while driving around the neighborhood.

We deployed the TFA Network using measurements from hundreds of fixed locations from mesh nodes deployed at 10 m (a typical installation) to the ground (access links) and to a portable node set up at 10m for backhaul links. For each location we measure the received signal strength and the achievable UDP throughput to the mesh nodes. Further, we measure multihop throughput from TFA nodes in a chain topology to evaluate multihop throughput performance along the mesh infrastructure.

We provide measurements that characterize how vehicular mobility is performed in the neighborhood of the TFA Network. The neighborhood's environment imposes mobility constraints that are typical both for i) a residential area and ii) a commercial area with high-speed roads. We correlate GPS coordinates with time instances of a vehicle's movement across every street of the neighborhood. The provided measurements describe vehicular movement for more than 14 hrs. Those can be used e.g., for simulation purposes, where client mobility emulates a realistic realization of movement around an actual placement of Access Points.

Here we provide measurements obtained by the Rice Networks Group that characterize the GoogleWiFi Network.

We characterize the coverage of the GoogleWiFi Network in Mountain View, CA by providing a set of results that describes the received signal strength from all surrounding APs. The methodology employs a wardriving process to collect values for signal strength reception from beacons collected with the Netstumbler tool, while driving around the network.
