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
3
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

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)
5
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
6
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
7
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
8
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.
15
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.
16
Demo



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
