GENERATION ACTIVE RFID
Network A is a connected network of 5 MRs. It is somewhat shaped as a straight line. However,
there are not many paths available and this network could suffer from bottlenecks. There are in total
6 connections. The GW has only 1 hop 1 connection. There are 3 potential bottlenecks.
In network B two additional MRs are placed at strategic locations. Placing them in such a way you
introduce 7 more connections, bringing the total to 13. The most important improvement is that the
GW now has 2 hop 1 connections. Furthermore, the new situation results in all MRs having at least 2
available connections, and most have more. Also, no direct bottlenecks are visible, though the SP
load still needs to be taken into account.
Of course, preferably in this situation, it is even better to move the gateway to the center of the
network to reduce the hop count.
7.4.3 Avoid Interference
Make sure you place GWs and MRs as far away as possible from appliances such as cordless
telephones, microwaves, televisions and such. This will significantly reduce any interferences that
the appliances might cause since they operate on the same frequency.
7.4.4 Security
Don't give other parties the chance to affect the stability of your networks. Change the default keys
of your nodes prior to deployment so you have a secure network. Please refer to the Ambient Studio
User Manual on how to perform such changes. Make sure you keep track of your network keys!
