WZRDnet Operation Manual 5 SECTION 1: GENERAL INFORMATION 1. Introduction This document forms the user manual for the WZRDnet handheld device Model WHD-310(V)1. As such it presents a detailed equipment description including the physical characteristics and operational instructions for the device. 2. Features The WHD-310(V)1 is a portable handheld wireless communication device that is a key element of the WZRDnet low-power wireless ad-hoc mesh network. The mesh architecture of the network facilitates wireless communication between handheld devices without infrastructure (e.g. satellites, cell towers, etc.). Every device in the network acts as both a router and a data/ voice terminal. This design creates a robust network without distance limitations or expensive maintenance. The devices automatically associate themselves with a network and are assigned a dynamic network address and ID. This self-forming, ad-hoc configuration eliminates the need for additional overhead or external monitoring. A device that is part of a network is referred to as a node. Nodes can send voice or data messages to other specific nodes or talk groups. The innovative voice and data communication methods of the WHD-310(V)1 feature the following capabilities: WZRDtalk™ allows peer-to-peer and talk group voice communications. The handset also allows communications with users on the WZDRnet network and stations on external Wide Area Networks (WANs). WZRDtext™ allows users to transmit text messages of unlimited length including files to other users or to multiple users. A message archive maintains sent and received messages on the device until deleted by the user. WZRDchat™ uses a USB connection to provide a user-friendly PC interface for text messaging and network monitoring. WZRDchat also allows uploading of GPS coordinates and modification of node settings. The WZRDchat application serves as a gateway to a local Personal Computer (PC) and the Internet where available. WZRDalert™ broadcasts text alerts/ notifications to all users on the network.

WZRDnet Operation Manual 8 SECTION 3: DEVICE POWER 1. Device Power Main power to the WHD-310(V)1 is provided by two internal rechargeable 1800mAhr Lithium Polymer batteries or by an external power source connected to the Device’s USB port such as a wall charger or PC. The internal batteries are constantly monitored and protected by an embedded battery gauge circuit. They are recharged whenever an external power source is connected to the USB port. An internal charger circuit determines whether the power is being supplied by the batteries or through an external power source. The Device’s on-board voltage regulator provides three separate outputs of 3.3VDC each. One output powers the microcontroller, and the other two power the peripherals and the DC-DC converter for the Liquid Crystal Display (LCD) backlight. 1.1 Battery Charging The batteries are recharged via the USB port. This can be done by connecting to the USB port of a PC or to a 5VDC 500mA to 1A wall charger. The Device will automatically determine which charging method is being used and configure itself accordingly. 1.2 Battery Gauge The current state of the Device’s batteries is displayed with a battery icon on the LCD screen. The user can monitor the voltage and be alerted when the battery is low. When the battery voltage drops below a predetermined level, the device will shut down automatically to save power.
WZRDnet Operation Manual 9 SECTION 4: MODES OF OPERATION 1. Start-up Mode The Device enters the Start-up Mode when the batteries are charged and the center button of the keypad is pressed. It can also enter this mode automatically through a Real-Time Clock alarm. In the absence of charged batteries, the Device enters the Start-up Mode when an external power source, i.e., a PC or a wall charger is connected to the USB port. When Start-up Mode is entered, the microcontroller first checks the condition of the battery supply to determine if it should proceed to Power-on Mode. 2. Power-on Mode The Device is in Power-on Mode when the user is interacting with the device and the device is running at maximum clock frequency with all the peripherals fully functional. Because this mode consumes the most power, the device will go into either Idle Mode or Power-off Mode to preserve battery life as soon as conditions permit. 3. Idle Mode The Device enters Idle Mode when the user is inactive for a predetermined amount of time and the USB port is not connected to an external power source, i.e., a PC or a wall charger. In Idle Mode the LCD screen is disabled and the microprocessor runs at minimal clock frequency of 500Hz in order to preserve power. In Idle Mode, the RF transceiver remains active as a repeater in order to interchange messages inside the mesh network. If the transceiver receives a message for the Device, then the Device transitions to Power-on Mode and the microprocessor resumes running at the higher clock frequency, while the LCD remains off, in order to analyze the received message. If the received message packet is not for the Device, then the Device returns to Idle Mode. 4. No LCD Mode The Device enters the No LCD Mode when the user is inactive for a predetermined amount of time and the USB port is connected to an external power source, i.e., a PC or a wall charger. Note that the Device does not go into a complete Idle Mode in order to allow the USB to continue charging the batteries. The LCD will turn back on when any button is pressed or upon message receipt. 5. Power-off Mode The Device enters the Power-off Mode by a controlled powering off sequence or by an uncontrolled power off sequence. Both sequences will cause the main regulator to be disabled as the voltage supply disappears, thus the Device would remain off.
WZRDnet Operation Manual 10 5.1 Controlled Power-off The WHD-310(V)1 can be powered off by pressing the center button of the keypad for 1 second. 5.2 Uncontrolled Power-off The Device is powered off automatically if the battery voltage falls below a predetermined threshold or if the battery is removed from the Device. The Device is also powered off when the battery gauge disconnects the battery due to over temperature, over voltage, or under voltage. Return to the Power-on Mode occurs when an external power source, i.e., a PC or a wall charger is connected to the USB port or a charged battery is inserted. 6. No Supply Mode The Device enters this mode if the battery is completely depleted and the voltage level falls below the undervoltage threshold. Return to the Power-on Mode occurs when an external power source, i.e., a PC or a wall charger is connected to the USB port or a charged battery is inserted.
WZRDnet Operation Manual 11 SECTION 5: NETWORK COMMUNICATIONS 1. Overview The networking technology employed by WZRDnet is based on the IEEE 802.15.4 protocol. Each Wireless Mesh Network (WMN) and is defined with a unique WMN Identifier (WMN ID). 2. Mesh Networking WZRDnet supports mesh routing, allowing data packets to traverse multiple nodes in order to reach the destination node. This allows nodes to be spread out over a large region, and still support communications among all devices in the network. 3. Network Device Types The following two device types exist in the network: 3.1 Coordinator A Coordinator selects a channel and WMN ID at the formation of a network. After starting the network a Coordinator behaves like a router except that it maintains the capability of updating network encryption keys. 3.2 Router A Router must join a WMN before it can transmit, receive, or route data. After joining, it can allow other Routers to join the network. It assists in routing data and therefore its RF section must remain fully-powered. 4. Ad-Hoc Network WZRDnet is an ad-hoc network that is a comprised of self-configuring devices. These devices either form a new network or join the nearest available network. The ad-hoc architecture allows new devices to automatically join a network without manual configuration. This encourages large-scale networks with minimal infrastructure support required. 4.1 Network Formation The Coordinator is responsible for initiating a network. Networks are formed when a coordinator selects a channel and WMN ID. To start a WMN, the coordinator performs an energy scan in order to discover RF activity on different channels as well as a WMN scan to identify nearby operating WMNs. 4.1.1 Energy Scan When a Coordinator powers up for the first time, it performs an energy scan on multiple channels (frequencies) to detect energy levels on each channel. Channels with excessive detected energy levels are removed from its list of potential channels. When the energy scan is complete, the Coordinator scans the remaining quiet channels for existing WMNs.
WZRDnet Operation Manual 12 4.1.2 WMN Scan A WMN Scan allows the Coordinator to detect nearby WMN IDs in order to avoid duplication. The Coordinator sends a broadcast information request and all nearby Coordinators and Routers respond with information about their specific WMNs including WMN ID, and whether or not joining is allowed. Once the Coordinator has completed the scans, it parses all received responses and creates a WMN with an unused WMN ID on a channel with minimal traffic. 4.2 Joining a WMN Routers must discover and join a WMN in order to be part of a network. They first issue a WMN scan and receive a list of responses from nearby nodes. They then parse this list to find valid candidate networks. Routers can be configured to join any WMN, or to only join a WMN with a specific WMN ID. However, they must always find a Coordinator or Router that allows joining. When they discover a device operating on a valid network that also allows joining, they attempt to join the WMN by sending an association request to that device. 4.3 Allowing Joining The Coordinator and Routers can allow or not allow new Routers to join the network. The number of Routers that can join is only restricted by the number of network addresses. 5. Network Addressing The 802.15.4 protocol specifies two address types: • 16-bit network address • 64-bit MAC address A Node Identifier String can also be specified which will route to the underlying address. 5.1 16-bit Network Address A 16-bit network address is assigned to a node when it joins a network. The network address is unique to each node in the network. However, network addresses are not static and can change. The 16-bit address must be discovered before transmitting data to a node. 5.2 64-bit MAC Address Each node contains a unique IEEE defined 64-bit MAC address. The 64-bit address uniquely identifies a node and is static.
WZRDnet Operation Manual 13 5.3 Node Identifier String (NI) A node can also be assigned a character based Node ID. This Node ID can be used to identify the node in order to route messages. The node ID will then be linked to the corresponding network address for packet transmission. 6. Broadcast Transmission Broadcast transmissions are intended to be propagated throughout the entire network such that all nodes receive the transmission. This is useful for emergency alerts or network notifications. Each WHD-310(V)1 comes with the ability to broadcast text messages as a standard feature. 7. Node Discovery A node discovery mechanism can be used to discover all modules that have joined a network. A node discovery sends a broadcast discovery transmission throughout the network. All devices that receive the command will send a response that includes the device’s addressing information, Node Identifier String, and other relevant information. 8. Node Search The WHD-310(V)1 provides the ability to search for a specific node based on the assigned Node Identifier String.
WZRDnet Operation Manual 14 SECTION 6: WZRDnet COMMUNICATION UTILITIES 1. WZRDtalk Voice Communication WZRDtalk is the voice communication utility of the WHD-310(V)1 which allows users to send and receive voice quickly and seamlessly. Voice messages are played out loud through an integrated speaker or through a Push-To-Talk (PTT) headset for private conversations. The WHD-310(V)1’s speaker should never be held against a user’s head. 1.1 Call Initiation The call originator selects a destination and initiates a call to that destination. After a call is initiated by pressing and holding the PTT button, an invitation is sent to the destination. 1.2 Call Invitation The call invitation determines the operating status of the destination. The destination hears an audible alert that an invitation was received. The system then automatically responds whether the user is ready to accept calls or is busy. 1.3 Call Establishment The call originator receives an audible alert if a response to the invitation was received and the destination is ready to accept the call. The response is received approximately 1-3 second after the call was initiated depending on the location of the destination and the status of the routing path. If the user is out of range and no response is received, a message will be displayed informing the user that the call has failed. 1.4 Call Communication After a call is established the call originator will continue to hold the PTT button and begin talking. 1.5 Call Disconnect A call disconnect is sent automatically when the user is finished speaking and the PTT button is released. 1.6 Call Reply The call remains active for 15 seconds after each communication. The active status will allow the call originator and destination to communicate with each other by simply pushing the PTT button. After 15 seconds the call status will become inactive. The originator and destination will then have to go through the call initiation process. Alternatively it is possible to connect via the Speed Dial feature described below.
WZRDnet Operation Manual 15 Figure 6.1 WZRDtalk Process 2. External Network Dialing WZRDnet allows any device to communicate with external Wide Area Networks (WANs) by providing a mechanism to transfer voice or data to the following external networks and utilities: Public Switched Telephone Network (PSTN) • Provides analog voice communication via landline or mobile telephones. Session Initiation Protocol (SIP) Phone • SIP is a signaling protocol that is used to control voice communication over Internet Protocol (IP). A SIP phone is a hardware-based or software-based SIP user agent, that provides call functions such as dial, answer, reject, hold/unhold, and call transfer. Instant Messaging (IM) Client • An IM client is a service that is based on either of the following real-time communication protocols developed by the Internet Engineering Task Force (IETF): o SIMPLE - Session Initiation Protocol for Instant Messaging and Presence Leveraging Extensions. o XMPP - Extensible Messaging and Presence Protocol (XMPP) which is an open source XML-based protocol.
WZRDnet Operation Manual 16 Figure 6.2 Sample External Dialing Network Design 2.1 External Dialing Elements The key WZRDnet element which supports the external dialing feature is the WZRDgate™. This element consists of a hardware unit and internal supporting software. The key components of the WZRDgate are described in the following: 2.1.1 WZRDnet Access Point The WZRDnet Access Point (WAP) can be either embedded in the WZRDgate or act as a standalone piece of equipment. It provides a wireless link between the WZRDnet network and the WAN realm and performs the adaptation of a WZRDnet packet to a WAN format. A single WAP can process multiple calls simultaneously. In operation, a WHD-310(V)1 desiring to send a voice segment to a WAN destination will identify the WAP in closest proximity to it. The voice segment, defined as the time between pressing and releasing the PTT button, will be
WZRDnet Operation Manual 17 processed through the same WAP. The WAP can change over the course of a “call” but not within a single voice segment. 2.1.2 Gateway The Gateway resides in the WZRDgate and consists of software that receives packets and sends them to a SIP server for processing. The Gateway also converts inbound messages back into the WZRDnet packet format for transmission to a WHD-310(V)1 handset. 2.1.3 Connectivity The WAP is able to transfer packets between the WZRDnet and the WAN via Wi-Fi, Ethernet or Serial transmission. 2.1.4 Device Registration WHD-310(V)1 devices and WAP register automatically with the Gateway. The Gateway maintains a constant list of all devices in the network including their MAC addresses and other identifying information. 2.1.5 WHD-310(V)1 Location Identification Each WHD-310(V)1 sends a registration message to the Gateway at a pre-determined interval. The Gateway uses this information to identify the nearest WAP to the WHD-310(V)1. This information is used to route inbound calls to a WHD-310(V)1 and provides the highest chance of a successful connection. 2.1.6 Hosting The SIP server can be hosted locally or remotely depending on the user’s needs. 3. WZRDgroup™ Talk Group Communications WZRDGroup provides communication with multiple users simultaneously. Users can establish “talk groups” without the need of a group administrator. A user can add or remove themselves from a talk group directly from the handset. This approach allows the group to remain dynamic and eliminates the need for a group administrator to maintain the list of members. An alert will be forwarded to the existing members of the group declaring the arrival or removal of a new member. While this design allows large scale talk groups, call quality deteriorates when talk groups reach more than 5 users. A user can be a member of up to 10 different talk groups. 4. WZRDtext Text Messaging The WZRDtext feature allows devices to send and receive text messages rapidly and effectively. The user selects a destination based on the Node Identifier String. The messaging component includes utilities to bolster network communication.
WZRDnet Operation Manual 18 4.1 Acknowledgments Upon receipt of a new message, the Device will automatically send an acknowledgement to the sender. The sender will then be able to determine if the message reached its destination. 4.2 Long-Term Message Storage The Device will store up to 30 sent messages and 30 received messages. A new message will automatically override the oldest message eliminating the need for message maintenance. The messages can be deleted or replied to at any time. 5. WZRDchat PC Instant Messaging WZRDchat is a java-based PC application that can be used to send instant messages to other nodes on the network. A node is attached to a PC using a USB connector cable. The user can then monitor the network and send instant messages to other nodes from the PC keyboard. 6. WZRDalert Network-Wide Notification The WZRDalert feature broadcasts a text message to all users on the network for emergency alerts or notifications.
WZRDnet Operation Manual 19 SECTION 7: SECURE COMMUNICATIONS 1. Encryption The WZRDnet system can be set for secure or non-secure communication. If security is enabled, the network employs 128-bit AES encryption with both a network security key and link key. Only devices that have the same security keys can communicate on the WMN. Routers that join a secure WMN must obtain the correct security keys. 1.1 Link Key The link key is pre-defined and installed on each Router that wishes to join a secure network. The link key is used to encrypt the network key which is sent to devices upon joining the network. 1.2 Network Key The Coordinator distributes a network security key when forming the network and periodically based on the Key Update Interval. Routers obtain the key when they join the network. The network key is encrypted with the preinstalled link key and is transmitted securely to joining routers by the Coordinator. The network security key is used to apply 128-bit AES encryption to all network level transmissions. Network layer security is applied on a hop-by-hop basis. As each node along a route receives an encrypted packet, it decrypts and authenticates the packet before processing it. When forwarding the packet to the next hop, the node re-encrypts the packet. 1.3 Key Update Interval The administrator sets a periodic interval for the Coordinator to update the Network Key. The Key Update Interval can be a specific number of days or hours. The Network Key is generated randomly by the system.
WZRDnet Operation Manual 20 SECTION 8: Global Positioning System (GPS) 1. GPS Locator The WHD-310(V)1 includes an embedded GPS locator which provides the local GPS latitude and longitude position. 2. GPS Clock Sync The WHD-310(V)1 allows syncing of the time to the GPS clock. GPS time is reported in Greenwich Mean Time (GMT). The user has the ability to maintain a local time offset that will automatically recalculate the time to the local time before syncing. 3. GPS Tracking The WHD-310(V)1 allows local storage of GPS coordinates along with a description. The coordinates, user description and timestamp can be uploaded to a PC via the WZRDchat software. These coordinates can then be displayed on a map. 4. GPS Mapping A file of captured GPS coordinates can be uploaded to a PC for visual display on a map. The file of GPS coordinates will be stored in a formatted .CSV file for upload into any internet GPS mapping software.
