Access by the requesting DUTs to respective PoAs may be predetermined so as to control loading of the PoAs during testing. ## Claims ### Claim 1 A method for controlling uses of respective tester points of access during wireless testing of one or more radio frequency (RF) signal transceiver devices under test (DUTs), comprising: receiving, via a first wireless point of access (PoA) of a plurality of PoAs, a request by a DUT for access, wherein said request includes a unique device identifier associated with said DUT; determining, based on said unique device identifier included in said request, an eligibility of said DUT for access via said first PoA; responsive to a determination of eligibility of said DUT for access via said first PoA, enabling access by said DUT via said first PoA; responsive to a determination of eligibility of said DUT for access via a second PoA of said plurality of PoAs, transmitting a redirection message for said DUT with an identifier for said second PoA; receiving, via said second PoA, another request by said DUT for access via said second PoA, wherein said another request includes said unique device identifier; and enabling access by said DUT via said second PoA. ### Claim 2 (depends on 1) The method of claim 1, wherein said determining, based on said unique device identifier included in said request, an eligibility of said DUT for access via said first PoA comprises comparing said unique device identifier with one or more predetermined device identifiers. ### Claim 3 (depends on 2) The method of claim 2, wherein said comparing said unique device identifier with one or more predetermined device identifiers comprises comparing said unique device identifier with one or more programmable device identifiers. ### Claim 4 (depends on 2) The method of claim 2, wherein said comparing said unique device identifier with one or more predetermined device identifiers comprises comparing said unique device identifier with one or more predetermined device identifiers stored locally. ### Claim 5 (depends on 2) The method of claim 2, wherein said comparing said unique device identifier with one or more predetermined device identifiers comprises comparing said unique device identifier with one or more predetermined device identifiers stored remotely. ### Claim 6 (depends on 2) The method of claim 2, further comprising determining, based on said unique device identifier included in said another request, an eligibility of said DUT for access via said second PoA. ### Claim 7 (depends on 6) The method of claim 6, wherein said determining, based on said unique device identifier included in said another request, an eligibility of said DUT for access via said second PoA comprises comparing said unique device identifier with said one or more predetermined device identifiers. ### Claim 8 (depends on 7) The method of claim 7, wherein said comparing said unique device identifier with said one or more predetermined device identifiers comprises comparing said unique device identifier with one or more predetermined device identifiers stored locally. ### Claim 9 (depends on 7) The method of claim 7, wherein said comparing said unique device identifier with said one or more predetermined device identifiers comprises comparing said unique device identifier with one or more predetermined device identifiers stored remotely. ### Claim 10 (depends on 1) The method of claim 1, wherein: said receiving, via a first PoA of a plurality of PoAs, a request by a DUT for access comprises receiving said request via said first PoA in a shared tester; and said receiving, via said second PoA, another request by said DUT for access to said second PoA comprises receiving said another request via said second PoA in said shared tester. ### Claim 11 (depends on 1) The method of claim 1, wherein: said receiving, via a first PoA of a plurality of PoAs, a request by a DUT for access comprises receiving said request via said first PoA in a first tester; and said receiving, via said second PoA, another request by said DUT for access to said second PoA comprises receiving said another request via said second PoA in a second tester. ### Claim 12 (depends on 1) The method of claim 1, wherein: said receiving, via a first PoA of a plurality of PoAs, a request by a DUT for access comprises receiving said request via said first PoA in a tester; and said determining, based on said unique device identifier included in said request, an eligibility of said DUT for access via said first PoA comprises comparing, with said tester, said unique device identifier with one or more predetermined device identifiers. ### Claim 13 (depends on 1) The method of claim 1, wherein said DUT comprises a cellular device and said plurality of PoAs comprises a plurality of cells. ### Claim 14 (depends on 1) The method of claim 1, wherein said DUT comprises a Wi-Fi device and said plurality of PoAs comprises a plurality of channels.
