I do not believe that any of the following things belong in the requirements document.
1 Handoff’s to other technologies 2 VoIP may be a compelling use for an 802.20 system but 802.20 should not be picking Codec’s. The standard should require that latency below X jitter below Y and QOS allow ARQ to be disabled that enable VOIP to be used if it is desired by the operator or customer. 3 Call features do not belong at all in the document. 4 Call blocking when at MAC capacity should be supported for a variety of common signaling protocols SIP, SIP+ MGCP, H.323 etc. 5 Erlang estimates do not belong added to the PAR tables in the System Requirements section as they were not part of the PAR.
