Motorola S9 and the Touch (and other general Q's)

[kellybrf]

the cutting in and out likely has nothing to do with the phone. if you actually read the s9 manual it addresses the issue, and tells you not to keep the phone in certain pockets, etc. i forget exactly what it says, but i now if i keep it in my back pocket i get/got the cutting in and out with my m610, upstage, muziq, q and touch

Already tested all the positions, found that to be most irrelevant. Consider the entire factor that Bluetooth is a short range radio signal 802.15 therefore making position not very troublesome based upon output frequencies of device.

Class
Maximum Permitted Power

mW(dBm)
Range (approximate)

Class 1

100 mW (20 dBm)
~100 meters

Class 2

2.5 mW (4 dBm)
~10 meters

Class 3

1 mW (0 dBm)
~1 meter

In most cases the effective range of class 2 devices is extended if they connect to a class 1 transceiver, compared to pure class 2 network. This is accomplished by higher sensitivity and transmitter power of the Class 1 device. The higher transmitter power of Class 1 device allows higher power to be received by the Class 2 device. Furthermore, higher sensitivity of Class 1 device allows reception of much lower transmitted power of the Class 2 devices. Thus, allowing operation of Class 2 devices at much higher distances.

[edit] Bluetooth 2.0

This version, specified on November 10, 2004, is backward-compatible with 1.1. The main enhancement is the introduction of an Enhanced Data Rate (EDR) of 3.0 Mbit/s. This has the following effects:[7]

• Three times faster transmission speed—up to 10 times in certain cases (up to 2.1 Mbit/s).
• Lower power consumption through a reduced duty cycle.
• Simplification of multi-link scenarios due to more available bandwidth.

The practical data transfer rate is 2.1 megabits per second and the basic signalling rate is about 3 megabits per second.[8] The "Bluetooth 2.0 + EDR" specification given at the Bluetooth Special Interest Group (SIG) includes EDR and there is no specification "Bluetooth 2.0" as used by many vendors. The HTC TyTN pocket PC phone, shows "Bluetooth 2.0 without EDR" on its data sheet.[9] In many cases it is not clear whether a product claiming to support "Bluetooth 2.0" actually supports the EDR higher transfer rate.
