    CCA. The MU broadcasts a probe with the Net_ID (ESS) and broadcast BSS_ID when the channel is transmission-free. It sends an ACK to a directed probe response from the AP , and updates the AP table. An Spectrum24 AP-4111 DS Access Point Product Reference Guide...

  • Page 28: Mobile Ip

    The MU changes its IP address when it moves to a new network, causing it to lose connection. Mobile IP enables an MU to communicate with other hosts using only its home IP address after changing its point-of-attachment to the internet/intranet. Spectrum24 AP-4111 DS Access Point Product Reference Guide...
  • Page 29 The scanning and association process continues for active MUs. This allows the MUs to find new APs and discard out-of-range or deactivated APs. By testing the airwaves, the MUs can choose the best network connection available. Spectrum24 AP-4111 DS Access Point Product Reference Guide...
  • Page 30 The MU and AP have to use the same key. If not, the AP refuses to become the Home Agent for the MU. The maximum key length is 13 characters. The AP allows all printable characters. Spectrum24 AP-4111 DS Access Point Product Reference Guide...

  • Page 31: Supporting Cam And Psp Stations

    When a Spectrum24 MU in PSP mode associates with an AP , it notifies the AP of its activity status. The Spectrum24 AP-4111 DS access point responds by buffering packets received for the MU. The Spectrum24 adapters use a PSP performance index from 1 to 5, where 1 provides the quickest response time and 5 provides the most efficient power consumption.
