  • shorter wavelengths can usually deliver higher bit rates.
  • a Bluetooth® signal at 2.4 Ghz can deliver audio quality better than a popular cordless phone at 900Mhz. This becomes an obstacle in and around water because higher frequencies are less effective in water. As discussed above, these obstacles may be overcome through several means.
  • One means is to include a buffering memory element in the ea ⁇ hone assembly.
  • the buffering element in the speaker continues the playback ofthe audio until the wireless signal is regained, or the buffering memory runs out.
  • the buffering memory may be chosen based upon the desired use of the system. If the system is to be used predominantly near the surface ofthe water, the buffering time might be chosen to be less than 5 minutes because that approaches the maximum amount of time a human would remain underwater without an air supply. Thus, audio data may be received at a faster- than-real-time rate when a user is above the surface ofthe water or near the surface of the water, allowing the user to listen to the buffered data when submersed deeper under the water.
  • the buffering time may be longer than 5 minutes, such as to accommodate the length of a SCUBA dive.

  • Figure 26c illustrates a configuration where both ea ⁇ hone assemblies 2604 and 2605 are below the surface of the water while the wireless transmitter 2602 is above the water. Such a configuration may be encountered for short periods of time for near surface activities or for longer periods of time for under water activities such as SCUBA or SNUBA when the wireless data source assembly 2600 is permanently outside the water during the aquatic activity.
  • buffering or other techniques may be used to ensure continuous audio transmission to a user.

  • Figure 26d illustrates a configuration analogous to Figure 26c, where the signal to both ea ⁇ hone assemblies must travel through both water and air. In such a configuration, the techniques described above may be used to ensure continuous audio transmission to a user.
  • Figure 26e illustrates a configuration where both the electronic audio device and wireless transmitter are below the surface ofthe water, and the speaker set is below the surface ofthe water.
