2 NETNode IP MESH Radio NETNode IP Mesh Radio: The Performance of COFDM with the Flexibility of IP Enhanced IP performance Embedded High performance Video Encoder (option)

3 What does the NETNode IP MESH Radio System Do Today? Key System Features Enables up to 12 IP Radio nodes to connect together in a Fluid Self Healing Mesh. The mesh operates on either a single narrow band or a wideband frequency. Phase 3 Nodes include a NEW 6MHz Bandwidth mode providing up to 6.7Mbps The NETNode system employs COFDM for excellent range and NLOS capability. Up to 4 Maximum Ratio Combined receive antenna (MISO) or 1x4 MIMO The mesh is multi-directional. NetNode Features Each node can be a source of video, audio or IP data. Any node can act as a relay. The NETNode system can operate with IP cameras or composite cameras. Data Encryption with optional AES128/256. 1W radios as standard. (NEW 2W option available & higher powers supported)

4 Monitoring and Control options Simple Monitoring and Control Web browser control. Mission Commander - Comprehensive control and monitoring applications Store and Forward function GPS interface and mapping. Networking Features VLAN Support (up to 8 VLANs supported on the Mesh) Multiple Nodes on an IP Backbone provides an Infrastructure capability 2012 New Features (Phase 3 Product) 4-way Diversity antenna unit for high points & vehicle fits Built in H.264 Dual SD or single HD encoder - reduces size, power & provides better video quality Mini Mesh NETNode 100mW only but less than ½ the volume

5 What shape MESH can be constructed? Node 1 Node 2 Node 3 Node 4 Chain Network Ideal for range extension Node 1 Node 2 Node 5 Central Node Star Network Good for urban coverage especially if Central Node is a high point. Node 3 Node 4

6 What shape MESH can be constructed? Node 4 Node 1 Node 2 Node 6 Node 3 Node 5 Random Network Evolves organically Node 1a Frequency A Node 2a Node 1b Frequency B Node 2b Networks can be combined Networks operating at different frequencies can be combined at the IP layer. Node 3a Standard Ethernet Switch

7 NETNode IP MESH Radio In Use (Web Browser Interface) Connectivity of multiple vehicles with video and audio and GPS back to central location. User Map Data True networked integration of video, audio and GPS. Single frequency, narrow band network. Robust self healing communications network. Excellent range extension with hops User control with mapping and PTZ control. Video and Camera Control over IP

8 Not All MESH Systems are Equal True Fluid Self Forming Mesh any shape WIFI Yes WIMAX No typically star only. Central point of failure Motorola Canopy No typically star only. Central point of failure Cobham NETNode IP Mesh Yes True Mobile Performance No limited range Can be mobile No Yes Genuine Non Line of Sight No limited guard interval Limited non line of sight Limited non line of sight Yes Narrow Bandwidth No Not as narrow (3.5MHz) No Yes Fast MESH Entry / Exit Speed No No No Yes Custom security / military design No No No Yes

9 NETNode IP MESH is still COFDM NETNode IP MESH behaves just like Standard narrowband COFDM Video links = Immune to Multipath Main Signal Delayed Signal = Built in Guard Interval and Error Correction Received signal = Diversity gives protection against fading

10 NETNode IP MESH is Narrow Band Bandwidth is a precious commodity NETNode WIFI 2.5, 3, 3.5, 5 or 6MHz Bandwidth 11MHz Two 6MHz channels in one RF Band WIMAX 20MHz Typical Narrow bandwidths provide Better Sensitivity (longer range) Will fit in US or UK police channel plan Bit rate available drops >10Mbps Network in a local area >20 Users in same cell Up to 6.7Mbps in a Mesh (6MHz mode)

12 NETNode and SOLO/VMT are Partners Solo/VMT/VMD complements NETNode Solo / GMS VMT / DTC VMD: Small and low power, ideal for hides. COFDM Bodywire Easy to conceal. Excellent Image quality. Ideal for primary surveillance link. Simplex, unidirectional. NETNode IP MESH Radio: NETNode IP Radio Duplex, bi-directional. Ideal for distributing primary content to dispersed users. Ideal for providing secondary feeds. Ideal for networking multiple sensors and users in the target area.

13 NETNode and Standard COFDM integration Example Network 3 cameras connected to the Mesh Two from a standard COFDM Transmitters via an IP streaming COFDM receivers One connected directly to a Mesh Node COFDM Transmitters would typically be set to 300 to 600kbps SIF mode and then this data is streamed out of the COFDM Receiver into the Mesh The PC acts as a multi stream video viewer Node 1 Node 2 Node 5 Central Node Node 3 Node 4

22 Network Video Storage Compatibility Milestone Compatibility Internal MPEG-4 encoder First release is video only Follow up with PTZ camera support Allow very compact and power efficient integration of standard composite PTZ cameras with Mesh Nodes Considering Milestone support from within Mission Commander UVMS Compatibility Including Low Latency Mode

23 Multiple Nodes on a common IP Backbone Node 1 Node 2 Normally either Node #1 or Node #2 would have to be on the IP backbone not both! In today s Mesh system you can not have Node #1 and Node #2 on a common backbone

24 Urban Surveillance (Interlink mode) HQ Tower 1 Tower 2 Urban Area IP Backbone Tower 3 As long as the Nodes on the Towers can see each other then they can seamlessly handover a mesh Node between the Backbone Nodes

25 Interlink Mode It is now possible to link multiple nodes to a common IP Backbone Uses an IP tunnelling approach

26 VLAN - Enhanced IP Capability A virtual LAN, commonly known as a VLAN, allows a number of networks to share the same physical resource such as the mesh network. This makes it possible to have completely separate networks running over a common NetNode system. Addresses x Addresses x VLAN2 Addresses x VLAN1 Mesh Radio Network x VLAN3 Intelligent VLAN aware Switch x x x x

27 VLAN - Enhanced IP Capability The NetNode supports up to 8 separate VLANS on a mesh network. Each VLAN is maintained by a separate routing table within each NetNode. The netnode allows VLAN tagging and stripping on the two external Ethernet ports.
