... into one, and almost surely simplifies handover between networks. The internal state (e.g., absolute time, or channel estimate if the two networks share the same carrier frequency) is preserved ... SDR? The key, albeit subtle, difference is that a software- controlled radio is limited to functionality explicitly included by the designers, whereas a software- defined radio may be reprogramm...
