Or will they interfere with each other in some way? Each tower has a fixed amount of spectrum and capacity that can be shared between users. 4G, like 3G and even GPRS, allocates capacity using a slot system, so each device on the network that wants to use the data service is allocated a slot. When I was living in the bush I had 2 3G modems which meant a lot of the time I was competing with myself. On the weekends when there were more users on the network I noticed a throughput drop on each link, but I got more bandwidth than I would have with 1. If there are 3 other users I would have got at least 2/5s of the slots, if there were 6 other users I would have got at least 1/4 of the slots. If your client is in a congested area, then there is a chance that 2 modems will improve their throughput, but if the network is lightly used, then they will see little benefit. If your client is serviced by multiple cells with poor signal, throughput will be compromised as the device continuously cell hops.
