Qualcomm began manufacturing its own branded CDMA cell phones during the early 1990s, then sold that division to Kyocera by the late 1990s. Qualcomm began integrating its 3G CDMA technology into many other manufacturers' telephones, including models by Sanyo and Ericsson. While Qualcomm-Kyocera branded cell phones are out on the market, Kyocera also has models that operate Qualcomm's technology, without the Qualcomm phone branding. Other mobile phones that carry the Qualcomm branding are satellite phones that do not operate on terrestrial 3G CDMA technology.
Some of the cell phone models that bear Qualcomm label for 3G CDMA technology include the QCP 1920, 2700 and 820. These models do not offer colour-rich graphics and advanced technology; however, they are user-friendly and cost-efficient, and provide standard features including caller ID, a phone book, text messaging, Internet browser and fax/modem capabilities. These are standard nonflip phones. More-advanced models include the 7135 Smartphone and QCP 6035 -- both flip phones.
Flip phone models that exclusively have Kyocera branding, while running on Qualcomm 3G CDMA technology include the Kyocera Deco E1000, Tempo E2000, Adreno S2400, K322, K325 (synonymous with the Virgin Mobile Cyclops), K127 and K325 (equivalent of the Virgin Mobile Marbl).
Touch-screen models include the Kyocera Zio M6000, Kyocera x-tc m2000 and Kyocera Laylo M1400; whereas the Kyocera S2300 Torino Loft offers a QWERTY keyboard. These offer various standard features and Bluetooth capability.
Sanyo offers a touch-screen via the Zio SCP-8600 and a QWERTY keyboard in the SCP- 2700. Flip phones include the SCP 8400, SCP 7000, SCP 8500 (synonymous with the Katana DLX) and MM-9000 (equivalent of the ESPN MVP). Standard nonflip models include the S1 and Sanyo SCP 6760 (synonymous with the Sanyo 6760 Incognito). All provide Bluetooth technology and standard features.
Ericsson/Sony Ericsson models that offer a full-sized keyboard include the P1i and 600I, while touch-screens are available with Xperia X1 and W910i. Flip phones include the Z750a and Z550; whereas standard nonflips are offered through the W810 and W810. All have standard features and Bluetooth capability.
Qualcomm Audio File
Qualcomm's audio files used on 3G CDMA are available under the software trade name PureVoice, which is traditionally associated with the file extension QCP. The Pure Voice suite offers voice recording and recognition technology that provides high-quality transmissions. Pure Voice also provides "audio automatic gain control," which is a stereo enhancement that filters background noise.
