Features
Optimized for highest performance and lowest cost Flexible Architecture (features easily added; mobile, handheld,
network) True 2-way radio link (allows controlling and programming
endpoints) High Performance RF Link (Long Range) High Data Rate (Selectable: 100 kbps or 50 kbps) High Endpoint Transmitter Power (100 mW) Low Endpoint Current (10 μA yields >10 year battery life) Low Endpoint Cost ($11 @ 100K excluding battery and case)
Modular and Extensible Reader Design Reader is Small and Light Weight (Easily moved between
vehicles)

Features: Flexible Architecture
Optimally supports mobile, handheld or network readers
New Endpoint features can be added without obsolescing the installed base
New message types are easily added Endpoints optimally support both full duplex
and half duplex readers Additional receivers can be added to the
reader receiver bus
4
Features: True 2-way radio link
Two-way link allows added features. A few Examples:
Remote programming Calling individual endpoints “by name” Setting the data rate for best performance Setting the number of transmissions per wake-up Set full or half duplex depending on reader type Changing the hop sequence to avoid interference Request different endpoint data sets
Monthly consumption and/or TOU data and/or Peak demand and/or Other data
5
Features: High Performance RF Link
Endpoints run 100 mW output power Mobile reader sensitivity approaches the
theoretical maximum Can handle 130 dB of path loss at 100 kbps and
133 dB of path loss at 50 kbps (for the geeks amongst us)
(This is very good performance) Measured range in excess of 3000’ line of sight
(range is determined by the path loss and varies according to the conditions)
Endpoint to reader link:902 to 928 MHz frequency hopping
Reader to endpoint Link:952 to 960 MHz MAS band (1.4 GHz optional)
6
Features: High Data Rate
100 kbps or 50 kbps Dynamically selectable (the reader controls the endpoint data
rate) 100 kbps for large files 50 kbps for hard-to-read situations
Supports high functionality meters having large data sets such as TOU
7
Features: High Endpoint Transmitter Power
100 mW Transmitter Output Power Long range Read from difficult situations
water meter pits basements long driveways
Supports higher data dates without range degradation
Battery or Mains Operation Low peak current allows use of AA Lithium battery Clever transmitter power supply for battery operation
99% battery power supply efficiency (higher than a charge pump)
Less than half the cost of a charge pump Rapidly comes on line reducing transmitter latency
No transformer required for mains operation, reducing cost
8
Features: Low Endpoint Current
Ultra low current superheterodyne receiver 10 microamps average receiver current 10 to 15 year battery life from a AA lithium cell Proprietary algorithms conserve energy
High power transmitter is very efficient 0.1 microamp average current
(based on 300 reads per month) Low peak transmitter current
(less than 5 mA above the peak receiver current) DC Power conversion circuitry is 99% efficient
9
Features:Modular and Extensible Mobile Reader
Separate transmitter, receiver, power supply, and decoder/controller assemblies
Additional receiver modules can be added to the control and data bus
Easily packaged into other form factors due to modular subsystem packaging

Mesh Network
Any endpoint can communicate with any other endpoint that is within RF range.
Electric endpoints can repeat messages for any other endpoint.
Battery powered endpoints can communicate with electric endpoints, although they do not repeat messages.
The top of each sub-net is connected to the control center through a public network such as telephone, 802.11, or cellular.
16
Mesh Network
Paths are source routed. Newly added endpoints are automatically
discovered and added to the network. Optimum primary and secondary paths are
computed to each endpoint.
17
Demo
Demonstrates a mobile reading system Uses a long message
38 bytes (304 bits) Longer than a typical TOU message Carries endpoint engineering data
Allows changing the endpoint parameters: Demonstrates some of the 2-way capabilities Data rate (50 kbps or 100 kbps) Number of times each endpoint repeats its message Frequency hopping on or off
