            |   | 36 | The large node is composed of one or more "sectors". Each sector is composed of a [wiki:Hardware/sdr/n310 USRP N310] and [wiki:Hardware/sdr/2974 USRP 2974] paired to an [wiki:Hardware/rf-front-end RF front end] and [wiki:Hardware/antennas#Directionallargenodesector directional antenna]. Additionally, there are several [wiki:Hardware/nodes/compute compute servers] located nearby for use in close conjunction with the USRPs. |
