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.

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.

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.

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.

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.
![](/img.php?id=1361539&img=bgc.png)
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.
![](/img.php?id=1361539&img=bgd.png)
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.

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.

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.

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
![](/img.php?id=1361539&img=bg11.png)
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.
![](/img.php?id=1361539&img=bg12.png)
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.

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
