| 5 | The Orbit grid as illustrated in Figure 1 consists of a multiply interconnected, 20-by-20 grid of '''ORBIT Radio Nodes''', some non-grid nodes to control R/F spectrum measurements and interference sources, and front-end, application and back-end servers. These servers support various ORBIT services. In addition to the main grid, there are also 9 additional smaller domains (a.k.a. sandboxes) |

| 10 | Each '''ORBIT Radio Node''' is a PC typically with two 100BaseT Ethernet ports, two or more radio cards and a Chassis Manager to control the node. The two Ethernet ports are connected to Data and Control subnet. While Control is used primarily for node access, experiment management and measurement collection, the Data subnet is exclusively available to the experimenter. |
