3. Business Challenges: “Can the industry offer a handheld
reader with fixed reader performance?” (from Unisys)
1. Many physical locations and process nodes cannot be
handled by either fixed reader or handheld reader
because:
1. Many locations do not allow fixed reader (loading zone, etc.)
2. Range from reader to tag is too long for handheld reader
3. There are water or metal content in between reader and tag
4. Because of 1, to 3, above, there are places where neither fixed
reader nor handheld reader work – hence loopholes of visibility
in the supply chain
4. Business Challenges #2: Read Rate of HHT
2. Inventory takes too long a time – if read rate can go up
10 times, inventory can be done
1. MUCH faster
2. MUCH more often
3. You can also do item level inventory much more easily
Benefits:
1. Replenishment of empty shelf daily
2. Reduce shrink, which is a SIZABLE cost in all warehouses and
department stores – in economic downturn, this is the fastest
way to improve profit !!
5. Business Challenges #3
3. Searching for an item is a daily necessity – but no way
to do that effectively:
1. Searching for an item is needed in warehouse outgoing
shipment
2. Searching and selecting is also needed in distribution centers
3. Searching is also needed for time critical fast retrieval or
locating of assets or documents
Benefits:
1. Reduce time of search and hence COST
2. More satisfied customers, therefore company more competitive
6. RFID Solutions: CS101 Handheld Reader
1. Read Range
• outdoor up to 7 meters for
VP, up to 9 meters for HP
• Indoor 8 to 12 meters
2. Read Rate:
• Up to 150 tags per second
DRM mode
• Up to 400 tags/sec non-
DRM mode
3. Geiger Counter Tag
Search:
• Search tag using Audio
Beep, beeps faster when
you get nearer to the tag
7. Results
Pallet is 2 meters x 2 meters,
diagonal 2.8 meters
Tags are horizontally mounted
Taking into account water content
or metal content causing 50%
reduction in read range
∴ Read Range > 6 Meters is
needed
8. Results
if you have 300,000 tagged
items to inventory,
If read rate = 10 tags/sec,
you need 8 hours
If read rate = 100 tags/sec,
you need 50 minutes
9. Results
Because of the
breakthrough in read range
and read rate of CS101,
Continuous Real Time
Inventory of Department
Stores or Supermarket is
possible because the
CS101 handheld reader can
be skillfully used by an
operator without disturbing
normal business activities
10. Results
Document Search is a daily chore
by MANY companies in the world.
Up to 10% time per day is spent on
searching document – if solved, this
is automatically 10% improvement
in productivity
The long range Geiger Counter Tag
Search function is VERY useful in
that area
11. Geiger Counter Tag Search
1) Operator picks up the tag at 7 meters away
2) Operator walks toward it and hear the beeping frequency increases
3) If operator walks away from it, the beeping frequency decreases
1 Beep Per 1 Beep 2 Beeps 3 Beeps Final 10 cm:
2 Seconds Per Per Per Sing a Song
Second Second Second
12. Results Geiger Counter Tag Search: Loci of Search
1. Operator can swing around
360 degrees to catch all
7 meters areas around him quickly
2. Circle is larger indoor
7 meters
7 meters 3. Circle is very large in metal
wall confined structures
150
square 4. Circle is smaller when
7 meters meters !! blocked or lots of water rich
content or tag is near metal
content
13. Results
1. Electronic Vehicle
Registration (EVR) tag is
becoming popular
2. Police needs a long read
range handheld reader
3. One of the earliest market
request to CSL !!
14. Results
Even better, a GSM/GPRS +
GPS Plug-in makes it location
capable outdoor (can couple
with Google Map !!)
15. Results – Indoor Passive+Active RTLS
For indoor, an RTLS Plug-in
with +/- 1 meter resolution
makes it location capable indoor.
Coupling that with floor map
software, one can then easily
location map all passive tag
tagged items
