INCREASING THE SPEED LIMIT FOR WIRELESS BROADBAND Bill Cusack - PowerPoint PPT Presentation

802.11 MUNICIPAL WI-FI • Limited security • No priority for government users • One point of failure can disable network Municipal WiFi networks are designed for surfing the Internet

802.11 MUNICIPAL WI-FI Do you want to share your traffic management network with him?

BEYOND WI-FI – MESH NETWORKS Wireless broadband optimized for government users

BEYOND WI-FI – MESH NETWORKS • Secure, private network • Licensed 4.9 GHz frequencies • Network can survive multiple failures Wireless broadband optimized for government users

MESH-ENABLED ARCHITECTURE (MEA) Mobility and seamless connectivity

MESH-ENABLED ARCHITECTURE (MEA) Ad hoc networking and range extension

MESH-ENABLED ARCHITECTURE (MEA) Reliability – automatic signal rerouting

CITY OF PROVIDENCE MESH NETWORK 200 client devices, 469 wireless routers, 51 access points

CITY OF PROVIDENCE BACKHAUL PTP microwave or digital cable – 51 backhaul connections

MESH NETWORKS Designed for mobility and customized coverage

MESH FOR TRAFFIC MANAGEMENT Wireless equipment integrated in traffic light controller cabinet

MESH FOR TRAFFIC MANAGEMENT Chandler, Arizona – wireless intersection control

MESH FOR TRAFFIC MANAGEMENT Why dig a trench to run cable under the road?

MESH FOR TRAFFIC MANAGEMENT CHANDLER, ARIZONA Challenge • Construction project eliminated traffic “All three controller cables at 3 major intersections intersections were Solution wired and • MESH wireless network solution replaced communicating in control cables less than 8 hours total time.” Benefits • Wireless traffic signal control without Matt Zinn backhoe fade Product Manager for Strategic • Video from intersections sent to Traffic Partnerships, Siemens Traffic Management Center Solutions

MESH FOR TRAFFIC MANAGEMENT MESH, point-to-point and point-to-multipoint wireless broadband

MESH FOR TRAFFIC MANAGEMENT • Addison • Frisco • Grapevine • Bedford • Grand Prairie MESH, point-to-point and point-to-multipoint wireless broadband

MESH FOR PUBLIC SAFETY LAPD Jordan Downs housing project

MESH FOR PUBLIC SAFETY Surveillance video is monitored at the command center

MESH FOR PUBLIC SAFETY And sent real-time to the responding officers

MESH FOR PUBLIC SAFETY Crime was reduced 40% after system installation

NEXT GENERATION WIRELESS BROADBAND Why would you choose LTE over MESH?

SO HOW FAST IS 4G LTE? ~~ Average data transfer rates ~~ MP3 song 60 kbps CDMA 1X 11 mins 2G 115 kbps 6 mins EDGE 256 kbps UMTS 3 mins 3G 400 kbps EV-DO 2 mins 1.0 Mbps HSDPA 38 secs 4.0 Mbps WiMAX 10 secs 4G 4.0 Mbps LTE 10 secs 802.11g 3 sec 14.4 Mbps 0.0 0.5 1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5 5.0 (MB) LTE is not as fast as 802.11g or 802.11n

802.11 MESH NETWORKS MESH is cost-effective for smaller geographic areas

LTE (LONG TERM EVOLUTION) NETWORKS LTE is better suited for larger geographic areas

COVERAGE COMPARISON Voice & Data LTE Mesh/WiFi 700 MHz 700 MHz 2.4 or 4.9 GHz Lower bandwidth, High bandwidth, Very high bandwidth broadest coverage moderate coverage with focused area zone coverage 2 – 8 sq mi .07 – .5 sq mi 10 – 15 sq mi Urban Coverage .8 – 1.6 mi radius .15 – .4 mi radius 1.7 – 2.2 mi radius 100 – 700 sq mi 20 – 100 sq mi Not recommended Rural Coverage for rural 6 – 15 mi radius 3 – 6 mi radius # Sites Compared 1 site 2x - 5x sites >100x sites to 700 MHz Antenna height and frequency band determine coverage

4G PUBLIC NETWORKS AT 700 MHz Cellular networks designed for commercial use

4G PRIVATE NETWORKS AT 700 MHz Private networks dedicated for state and local government use

PRIORITY ON A PUBLIC 4G NETWORK Can you afford to share bandwidth with commercial users?

VIDEO ON AN AIRPORT BUS How many people on the rental car bus are checking e-mail?

VIDEO ON AN AIRPORT BUS Can surveillance video effectively share bandwidth with riders?

WHAT YOU’LL BE SEING SOON WITH LTE Will government agencies choose public or private networks?

MIXED PRIVATE AND PUBLIC LTE NETWORKS Private 4G network Public 4G network Roaming between public and private broadband networks

FASTER WIRELESS BROADBAND 1. High-speed technology 2. Broadband design choices 3. Optimizing your network The road to reliable wireless data and high-quality video

OPTIMIZING YOUR NETWORK How do you increase capacity with limited speed and bandwidth?

OPTIMIZING YOUR NETWORK What happens when you watch video on a slow network?

OPTIMIZING YOUR NETWORK Buffering video – please wait What happens when you watch video on a slow network?

OPTIMIZING YOUR NETWORK How can you optimize video on a busy network?

OPTIMIZING YOUR NETWORK • Quality of Service (QoS) • Adaptive bit rate • Frame rates that fit the application How can you optimize video on a busy network?

QUALITY OF SERVICE (QoS) Video quality is excellent when there’s no network traffic

QUALITY OF SERVICE (QoS) But what happens when the network is congested?
