| 3 | | Emulating mobility via spatial switching relies on a large number of static radio interfaces, whose antennas are arranged in a grid topology. To emulate moving nodes, the system will select sending and receiving radios from the grid that best represent the positions of the moving nodes as given by a mobility scenario. To emulate large-scale networks, an experimenter can utilize the ORBIT noise generation system to raise the noise floor in the environment, which emulates a greater distance between transmitter and receiver.

| | 3 | Emulating mobility via spatial switching relies on a large number of static radio interfaces, whose antennas are arranged in a grid topology. This system emulates mobility by switching a moving node to different radio and antenna positions as time progresses. Thus, the emulated path of a moving node comprises a number of discrete steps that approximate the actual path a moving node would take. To emulate larger distances between the nodes, an experimenter can utilize the [http://www.orbit-lab.org/wiki/Documentation/ArbInterference ORBIT noise generation system] to raise the noise floor in the environment, which emulates a greater distance between transmitter and receiver.
