Based on the above roles of thump, these guidelines must be followed:
Gateway locations
Location | Exhibits | Gateway |
Warehouse Storage aisles | Exh. |
4 |
Exh. |
5 Exh. |
6
| a) Place one gateway in every fifth (5) or sixth (6) storage aisles (one gateway to cover five to six storage aisles). b) Fasten the gateway upside down above the storage racks. Ideal location is on the load bearing beam in the ceiling. |
c) Use plastic cable ties to fasten the |
gateway |
d) If the warehouse stores water rich goods, the distance between gateways must be shorter
| |
Walk in cooler | Exh. |
7 Exh. 8 Exh. 9 | a) Gateway must be within 12m from the cooler b) Fasten the gateway at least above the traffic (forklifts etc.) c) Fasten the gateway with screw or cable ties Note. If if is difficult or inconvenient to place a gateway close to the cooler, a logger with a temperature probe can be used (CO 07.01 for EU). Then the logger is fasten outside of the cooler and the probe end is extended inside of the cooler |
Drive through freezer/cooler |
Exh. 10 | a) Short/small storage room – Place the gateway outside of the freezer/cooler room wall b) Long/large storage room – Place the gateway outside of the freezer/cooler wall and extend the RF antennas inside the storage room |
Note: Never place a gateway in environment where the temperature is below 0°C |
Storage cage
Depending on the mesh size
Warehouse docking |
| a) Fasten the gateway at high point on a column, facing the docking area. b) If there is no obstacle for the RF signal, one gateway can cover up to 50m in both directions |
Installing loggers
Loggers must not be placed within the stored goods or behind a metal (such as storage rack beam).
| Location | Exhibits | Logger |
|---|---|---|
| Storage shelfs | Exh. 11 | a) Place the logger on the shelf rack beam, facing the aisle. The RF antenna must be in a vertical position. b) Fasten the logger with cable ties. |
| Cooler/Freezer | Exc. 11 | a) Fasten the looger on the storage shelf with cable ties |
Exhibits - Warehouse storage aisles
...
(1) logger distributed over the storage aisles, (2) loggers in the docking area, (3), loggers in the drive-in freezer and cooler, (4) logger in the walk-in cooler and (4) logger in the storage cage.
Exhibit 3. Gateway location selected
(1) Gateways in storage aisles, 5 to 6 aisles apart,
...
Gateways (1), (2) and (3) placed above the storage racks. Gateway (4) fasten outside of the coolers and the RF antenna extended inside the coolers.
Exhibit 4. Gateway above storage racks
To ensure sufficient signal quality for loggers in the storage aisles, one gateway must be located every fith to sixth storage aisles. This depends of what kind of goods is stored in the aisles.
