Nokia Siemens Networks’ CFC feature allows 3G users extended device battery life
One thing that most smartphone owners may agree unanimously over is the fact that these devices seem to have battery lives that drain away pretty quickly. Nokia Siemens Networks has conducted what they claim to be is the first ever call utilizing a network technology called ‘continuous packet connectivity’ or CPC. Incorporating this technology into an HSPA + radio access network is cited to aid in extending batter life by a huge margin.
The CFC data call was carried out with network equipment from Nokia Siemens Networks and a Qualcomm device integrating the QSC6295 chipset. This technology is calculated to render around 100% extended battery life when devices are utilized for data applications and 50% more life during voice calls. Nokia Siemens Networks’ Flexi Base Station and radio network controller are capable of supporting the CPC feature with a software upgrade.
“Nokia Siemens Networks is focused on innovations that benefit both operators and end-users,” stated Tommi Uitto, head of Network Systems product management, Nokia Siemens Networks. “With CPC, subscribers will enjoy an improved mobile data experience, while operators will benefit from enhanced network capacity – even with heavy smartphone use – due to less interference in the radio connection, not to mention higher revenues due to increased usage of the service.”
This CPC feature of 3GPP Release 7 uses the discontinuous transmission and reception method to shut down the device’s transmitter and receiver during the idle phases to gut down power consumption without affecting data rates experienced by the user. HSPA data sessions leave a lot of idle time between data packet transfers leading to the device imbibing battery power unnecessarily.
Alex Katouzian, VP of product management for Qualcomm CDMA Technologies, commented, “At Qualcomm, we are committed to driving the evolution of technology features that provide the maximum benefit to end-users. The CPC feature further enhances the HSPA+ mobile broadband experience for end-users by allowing them to enjoy these services without worrying about device battery life.”
There is no clear word on when this CFC network technology will actually be implemented as yet.
