GENERATION ACTIVE RFID
It should be noted, however, that there is a chance that SPs do not consume the beacons provided by
the Infrastructure nodes in a evenly distributed way, so some margin for error needs to be taken
into account.
Calculate the accumulative SP load to identify potential congestion bottlenecks!
If an accumulative SP Load nears the maximum network bandwidth, place
additional Infrastructure nodes to introduce additional bandwidth!
7.3 Deployment Execution
After the Deployment Plan has been set up, it is time to start deploying the nodes according to the
plan. Every deployment starts with the GW since a network can not exist without it. Then, after the
Gateway has been set up, the MRs are added to the network. Finally, after the Infrastructure has
been deployed, we place the SPs at their target locations.
7.3.1 Mounting the Gateway / MicroRouter
Generally the GW and MR should be mounted such that the swivel antenna is always in vertical
position. This ensures the same polarization for all the antennas and in consequence best
connectivity. The above statement holds for both indoor and outdoor networks. Also, all MRs and
GWs should preferably be placed at the same height above the ground. For best radio performance
1.5 meters above the ground or higher but not closer than 1 meter to the ceiling.
Ensure all antennas are in vertical position for best radio performance.
As the GW and MR comes with a swivel antenna there are a number of considerations for placing
the MR and GW. Always try to place the GW or MR as far as possible from surrounding objects as
possible, such as large metallic objects, walls, pylons or other obstacles. Placing the antenna too
close to objects will alter the radiation efficiency so that less power is radiated into free space,
effectively reducing the range of the GW and/or MR.
Mount the GW and MR in such a way that its antenna has a good clearance. This ensures the best
performances and radiation efficiency. Keep in mind to avoid placing the antenna too close to
corners of the room. Mount the GWs and MRs at a height such that it radiates above most obstacles
such as metal cabinets for maximum performance.
Once you have selected a good position and orientation for mounting a GW or MR, use screws and a
screwdriver

to fix it in place. Then connect the node to the power using the AC adapter and wait for
it the go through the right sequence of the start-up procedure by observing its LEDs. The LED

sequences can be found in Illustration 29.
1 Only use screws of 5 mm diameter or thinner. If you use screws that are thicker, you risk damaging the enclosure.
2 When printing in grey colours, the led colours are from left to right, blue, green, orange and red.
