  • DES Node

    Wireless Mesh Routers

    The mesh routers are based on the PC Engines Alix2c2/Alix2d2 and Alix3d2 embedded PC boards with the following features:
    CPU 500 MHz AMD Geode LX800
    DRAM 256 MB DDR DRAM
    Ethernet 2 Ports
    WIFI 3 IEEE 802.11a/b/g
    Expansion 2 Mini PCI slots

    2 USB 2.0 ports

    Storage CompactFlash socket
    Eclosure Custom

    Each router is equipped with three IEEE 802.11a/b/g network interface cards (NICs). Currently, we use one LogiLink WL0025 dongle based on the RT2501U architecture with an RT2571W BB/MAC IC and RT2528 RF IC. This NIC features an on-board R-SMA connector and a 4 dBi Hi-Gain antenna. The antennas are mounted at the side panels of the router using extension cables. Additionally, all mesh routers are equipped with two Atheros-based MiniPCI cards (WLM54SAG) connected with dual-band antennasThe indoor nodes use a custom case that is manufactured at Freie Universität Berlin.

    Wireless Sensor Nodes

    Each mesh router is equipped with a MSB-A2 sensor node (developed at Freie Universität Berlin) that is connected via a USB cable which provides power supply and is used to write firmware images to the flash memory.

    The MSB-A2 sensor nodes use an LPC2387 microcontroller produced by NXP Semiconductors. The frequency of the 32-bit ARM7 TDMI-S core based microcontroller can be dynamically configured at runtime to up to 72 MHz, depending on the sensor network application and energy requirements. The TI (formerly Chipcon) CC1100 transceiver uses the ISM band at 863 to 870 MHz with a maximum data rate of 500 kbit/s. The MSB-A2 nodes set up a wireless testbed in parallel to the mesh routers that is fully orthogonal to the frequency band used by IEEE 802.11.

    The sensor nodes are equipped with a Sensirion SHT-11 temperature and humidity sensor. Depending on the experiment scenario, extensions are connected on-demand via the general purpose input/output pins (GPIO) or the second on-board mini USB port. In addition to the internal 512 KiB flash memory, microSD-cards can be used. Unlimited data storage is available via the Ethernet backbone provided by the mesh routers.

  • Atheros
    AR9380

    AR9380 is the single-chip, dual-band (2.4/5 GHz), 3-stream 11n solution with PCIe interface. It packs the breakthrough Signal Sustain Technology 3 (SST3) technology that enhances the rate-over-range (RoR) performance. SST3 is a set of advanced technologies and features enabled by 802.11n including LDPC, TxBF and MLD. This interface runs the Atheros ath9k driver which is included in the open-source compat-wireless drivers.

    AR5414

    It features the Atheros AR5414 chipset with Turbo/Super G (air rate 108Mbps on 802.11g 2.4GHz). R52 works on 2.312-2.499 and 4.920-6.100GHz frequency range. It runs the Atheros ath5k driver which is included in the open-source compat-wireless drivers, as well as the MadWifi driver.

  • NITOS Outdoor Nodes

    The upgraded Outdoor Nodes have been developed by the NITLab team and support MIMO operation.

    NITlab CM card

    In order to control and monitor Outdoor nodes' operation, we use NITlab's Chassis Manager Card (CM card). A tiny web server is running on the CM card and serves http requests, such as power on/off and reset commands. Further more, CM card can support real time sensor measurements, since it can be connected with temperature & humidity sensors, as well as with light sensors.

    m3 node

    Two leds are used to indicate the operational status of the outdoor nodes. More specifically a two state led, located on the side, indicates the power status of the node. If the led is red the node is turned off and if the led is blue the node is turned on. The same led flashes in red mode each time the cm card serves a request.
    The second led is on the cm card and indicates the connection of the node to the power supply.

  • Icarus Nodes

    NITlab has developed powerful Wi-Fi nodes, called ICARUS, in order to support the increasing demand of state-of-the-art resources for experimentation in NITOS facility. Experimenters are able to run and evaluate demanding processing algorithms and protocols in a large scale testbed.
