100m dual Ethernet backbone with consist ring (ETB) • high bandwidth for inter consist communication • no usage of the backbone if the consist travels alone • needs a repeater every 50m to compensate a switch fail with internal relays • 4 links per intra car / intra train connection repeater repeater repeater Confidential

WAC-1001 • Turbo Roaming • supports complete AWK family • 10/100/1000Mbit/s Ethernet • 50ms hand over betweens AP’s • WPA/WPA2 PSK and enterprise security (IEEE802.1X/RADIUS, TKIP and AES) • controls 200 AP’s Confidential
Automatic carriage coupling Confidential
AWK AWK AWK AWK AWK AWK Automatic carriage connection (ACC) • special firmware that triggers automatic connection • antennas should be deployed at center of both consist ends • coupling and decoupling threshold can be set to keep range very low while achieving full bandwidth central antenna position and ultra low range avoid that consists on adjacent tracks are accidentially coupling Confidential
Automatic carriage connection (ACC) • antenna deployment at corner of consist can reduce distance between radios not belonging to the same train AWK AWK AWK AWK Confidential
AWK AWK AWK AWK ACC coupling 1. consists approach each other and received signal strength increases 2. when signal strengths exceeds RSSI associate value RSSI ACA coupling starts • roles of master and slave are negotiated 3. after the ACC negotiation timeout the radios are connected • radios stay connected and accept no further connection RSSI RSSI ACA t ACC negotiation timeout Confidential
AWK AWK AWK AWK ACC decoupling • hysteresis between coupling and decoupling RSSI values avoids toggling when RSSI decreases (rain, train acceleration, ...) and allows to reduction of coupling range • ACC link timeout avoids that environment (spikes, microwaves etc.) cause decoupling • decoupling happens when signal strenght is for t ACC link timout permantly below RSSI RSSI RSSI ACA RSSI ACD t ACC link timeout Confidential
Train to ground communication Confidential
AWK AWK AWK AWK AWK AWK AWK AWK Train considerations • individual coaches without backbone • each coach has its own antenna • consist with backbone • lenght of train can be used to increase range (less access points needed at track), especially when using directed panel antennas (single consist) or external directed sharkfin antennas • loop avoidance needed to prevent loop c AWK AWK Confidential
Train antennas • internal antennas • no drilling of needed – often only solution for refurbishment projects • panel antennas at head and tail of a consists with backbone are a good option if mounted behind non-metallic part (acrylic glass etc.) • omnidirectional antennas provide only a short range when mounted within train • external antennas • Moxa made good experience with bi-directional sharkfin antennas Confidential
AWK AWK Tram / winding track • tram • generally many curves and low speed • often buildings in center of directional antenna‘s beam • little benefit from directional antennas with wide range buiding buiding Confidential
AWK AWK Bullet train / long straight open track • length of the train can be used, especially in combination with directed antennas at train and track to reduce the number of access points at the track and reduce the number of roamings Confidential
Subway / tunnels • narrow single track tubes reduce range and can generate blind spots that can‘t be reached from radios at head and tail of the consist • tubes with multiple tracks provide larger range C B A 200m distance between APs AP AP AP access point B is in blind spot when train is just under it AWK AWK 116m (lenght of subway) Confidential
AWK AWK Subway roaming (example) • head radio is connected to AP B • tail radio connects to AP A when AP B enters blind spot • head radio roams to AP C • tail radio connects to AP B when AP C enters blind spot B C A AP AP AP Confidential
AWK AWK AWK AWK Loop avoidance • access points are so far that always only one AP can be reached by train • gap becomes bigger under severe conditions (rain, ice, ...) • inter client roaming (concept) • clients at head and tail of the train cummunicate RSSI values and only one radio connects to access point AP AP AP AP Confidential
network A roams here network B roams here network A roams here Seamless connection • two clients with different channels & interleaved AP networks • PRP (parallel redundancy protocol in train and on track) • no roaming interruption as only one client is roaming at a time • doubles the number of access points • space diversity increases resilience against sparks AP AP AP AP Confidential
network A connects here network A disconnects here coverage of access point A network B connects here gap in network B to avoid need for roaming network B disconnects here Seamless connection (cont’d) • two or more clients with different channels & interleaved networks • PRP (parallel redundancy protocol in train and on trail) • no roaming interruption as one client connects to it‘s access point prior to connection loss of other client • no roaming needed as client can‘t access two access point from the same network at the same time • few access points but careful planning needed AP AP AP Confidential
Seamless connection – network • access point network • two networks connecting the access points • PRP capable switch connects networks to router • networks use different channels • in train • two clients using different channels • train switch runs PRP • networks use different channels • each client has two directed antennas (& amplifiers to compensate long antenna cable) and additional optional omnidirectional antennas for center of very long trains AP AP AP AP AP AP AP AP AP AP AP C C Confidential
