I worked for a GSM Middleware company for 3 years so I know a bit about the tech.
A CellBooster would probably have no effect, or very little effect, since the quality of your call is not determined by the phone, but rather the node you are in. They might only help in reducing the amount of lost packets. Cell Phones are Digital devices, not analog like a radio or standard SS7 landline telephones, so reception only plays a part in whether the packet is delivered or not, not the actual quality of the data.
The GSM towers are arranged in oval nodes that they can cover, and they have a relatively short distance.
Quality is determined by the settings of the network, and how long it takes for a signal to reach your phone.
Each second of broadcast time is split between the various converstations so every few milliseconds you will receive the data. The networks have very limited frequencies so they have to share frequencies between conversations, IIRC this process is called TDMA which basically means that broadcasting is time delimited.The lower the quality on the node is set to, the smaller the packets get (they use lossy encoding), and thus the more simultaneous calls can be serviced by that one node.
The higher quality the less calls can be serviced at any one time.
Reception only has an effect on your call when you are actually missing or not receiving some of the packets.
