WirelessLAN


Bat11b wlan overview
BAT11B WLAN Overview

  • Wireless LAN AP (Access Point)

    or

  • Wireless LAN AC (Access Client)

  • RF Technology:

    • 802.11b

  • Antenna Connection:

    • Two external RSMA antenna connections

      (For Diversity)

  • Range:

    • 11mbp/s: 160m Outdoors, 30m Indoors, depending on antenna positioning


BAT11B WLAN Overview

  • Transmission speed:

    • 11 Mbit/s (high)

    • 5.5 Mbit/s (middle)

    • 2 Mbit/s (standard)

    • 1 Mbit/s (st. low speed)

    • Automatic Rate Selection (ARS)

  • Encryption:

    • No encryption

    • 64 Bit (WEP)

    • 128 Bit RC4 and WEP plus (weak key avoidance)


BAT11B RF Module

  • Frequency band:

    • 2-4 to 2.4835 GHz (ISM band)

    • 13 channels

  • Modulation:

    • Direct Sequence Spread Spectrum (DSSS) with CCK, DQPSK, DBPSK, CCK

  • Spreading:

    • 11-chip Barker sequence

  • Delay spread (FER <1%):

    • 11 Mbit/s: 65 ns

    • 5.5 Mbit/s: 225 ns

    • 2 Mbit/s: 400 ns

    • 1 Mbit/s: 500 ns


BAT11B RF Module

  • Receiver sensitivity:

    • 11 Mbit/s: -82 dB

    • 5.5 Mbit/s: -87 dB

    • 2 Mbit/s: -91 dB

    • 1 Mbit/s: -94 dB

  • Bit error rate:

    • < 10-5

  • Transmitting power:

    • < 100 mW E.I.R.P. (ETSI); 15 dBm

  • Input voltage:

    • 9 to 36 V

  • Power consumption:


BAT11B Network

  • Media access protocol:

    • CSMA/CA with ACK

  • RF protocol:

    • IEEE 802.11b @ 11 Mbit/s and 5.5 Mbit/s,

  • IEEE 802.11 @ 2 Mbit/s and 1 Mbit/s

  • Topology:

    • Access point (infrastructure)

    • Access client (ad-hoc)


BAT11B Environmental

  • EMC interference immunity

    • EN 61000-4-2 Electrostatic discharge immunity test.

    • EN 61000-4-3 Radiated, radio-frequency, electromagnetic field immunity test

    • EN 61000-4-4 Electrical fast transient/burst

    • EN 61000-4-5 Surge immunity test

    • EN 61000-4-6 Immunity to conducted disturbances, induced by radio-frequency fields

  • EMC radiated and conducted interference

    • EN 55022 class A

  • Approvals

    • As per R&TTE directive 1999/5/EC

  • Operating Temperature

    • -20 to +70 C

  • Humidity

    • 0-95% non-condensing


BAT11B Display & Operation 1

  • LS1=Ethernet port 1

    &

  • LS2=Ethernet port 2

    • Connected to LAN -> green

  • DA1=Data Transmission

    &

  • DA2=Data Transmission

    • Minor data received -> intermittent orange

    • Major data received -> constant orange


BAT11B Display & Operation 2

  • LS WAN

    • No AP/AC connection -> Intermittent Green

    • Valid AP/AC operation -> green

    • AP operation -> green

  • DA WAN

    • Minor data received -> blinks orange

    • Major data received -> solid orange


BAT11B Configuration

  • Management

    • BAT Discovery

    • Web Interface

    • SNMP-???

  • Diagnostics

    • LED’s

    • Signal Contact/Fault Relays

  • Configuration

    • BAT Discovery

    • Web Interface

    • DHCP


BAT11B Access Point Operation

  • Example 1 - the BAT in LAN 1 acts as an Access Point and the BAT in LAN 2 works as an Access Client. All clients in LAN 2 are connected to the AP in LAN 1.


BAT11B Infrastructure Operation

  • Example 2 – All clients communicate via the access point. However, all AC's have to be located within the range of the access point.


BAT11B Ad-Hoc Operation

  • Example 2 – All clients communicate directly with each other. However, this method is not optimal as interference can occur with more regularity.
