What the author was going for was probably the fact that sprites that the TM compile have the same "resonance signature" as the TM, sprites are under the control of the TM, the TM is the "owner" of the sprite, if you track their physical location you end up with the location of the TM and the fact that TMs have a special sprite-TM communication link. However they are not a PAN in the true SR5 sense (in fact SR5 explicitly say that "Sprites are personas, but not devices; they can't be part of a PAN or WAN").
Having said that, it might or might not be able for a TM to slave her physical devices to a high firewall physical commlink, giving her a matrix PAN like any a regular person. Most TMs want to hide the fact that they are TMs and almost all TMs probably have a commlink that can broadcast a fake SIN anyway (also if you have Data Trail then you equip your commlink with a stealth dongle for a sleaze rating to make your PAN harder to spot when you run silent). Some TMs might even get a cyberdeck for the purpose of disguising as a decker rather than a TM.
