TCS2315 GPRS手机解决方案

                  Equipped with TIs scalable and hardware-based M-Shield™
                  security technology, a TCS2315 handset offers ironclad
                  protection of the owners personal information. M-Shield also
                  prevents the unlocking of the handsets SIMlock code, defeating
                  attempts to switch networks. High-value content and IP can be
                  fully protected from tampering, piracy and malicious attacks.

                  Innovative user form factors such as ultra-slim, clamshell and
                  candybar handsets are possible because of the reduced
                  component count and PCB board space requirements brought about
                  by the smaller 65-nm process node, increased integration, and
                  advanced packaging technologies for a single-chip solution. In
                  addition, a smaller PCB area requirement allows a handset to
                  support larger batteries for a longer battery life enabling
                  extended standby and talk times. The superb full-duplex
                  quality of voice service of the
                  “LoCosto ULC” solutions are comparable to more expensive
                  handsets. In fact, the voice loudness on both ends of a call
                  can be improved by 7 dB or practically twice as loud.
                  Moreover, voice chopping and double talk are reduced
                  dramatically, making handsets based on the TCS2305 and TCS2315
                  solutions very effective in handsfree applications and noisy
                  environments, characteristic of densely populated emerging
                  markets. The TCS2305 and TCS2315 also offer SMS text
                  messaging, a Universal Subscriber Identity
                  Module (USIM) interface for SIM cards and support for a
                  standard keypad and joy stick.
