A.2 Handset MS

03.503GPPTransmission planning aspects of the speech service in the GSM Public Land Mobile Network (PLMN) systemTS

The handset MS, depending on the detailed implementation, might not require the use of non‑linear processing for the acoustic echo control. Also, the position of the microphone should give a significantly improved signal‑to‑noise ratio, compared with a handsfree MS especially in noisy environments. This is likely to result in significantly improved transmission quality compared with the handsfree MS and easier duplex conversation.
