Cell Antennas Don't Play Nice

When investigating whether or not to get an implant, I looked into how security devices and other techie stuff impact the implant and its programming. There was talk that airport security systems would mess with the implant as do shopping security devices. In the end, these rarely have an impact on the implant and its programming.
With more and more things going wireless, you wonder if there are going to be implications. A family says cell antennas would signal trouble. What does this mean for implants?
