Synway SMG4000 Wireless Gateway could be compliable with a variety of wireless/mobile protocols (2G/3G/4G), enabling interconnection between GSM/CDMA/WCDMA network and VoIP network smoothly and safely. It is able to bridge wireless network with IP networks efficiently, regarding to the high-demanding user requirements. GSM4000 adapts self-propelled SIM card slots, advanced built-in VoIP processors and wireless modules, and helps enterprises and SPs launch diverse cost-efficient and flexible Wireless-to-IP communication systems. SMG4000 could also be applied into a range of systems, including remote billing and charge, Mobility PBX, PSTN backup lines, VoIP localization, SMS platform and more.

SMG4000 provides customers with efficient communication efficiency and helps them create more values, and both system integrators and users could benefit from a more reliable and versatile manner of transition between wireless and IP networks.  Some of specific values include:

• High-speed response and connectivity in the extreme network environments, with better run efficiency;

• Telecom grade reliability and continuous high performance in fully loaded capacity and in the long run;

• Homegrown hardware and software technologies to guarantee relevant upgrading and customization;  

• DSP-enabled voice optimization to assure crystal voice quality and maximize bandwidth efficiency;

• High security and privacy for users via automatic-exchange of different SIM cards and Networks;

• More compact hardware design to save space and ensure advantages of power consumption and cost ;

Functional Description: SMG4000 has attracted over 100 system integrators to use, although it has not emerged in the market for a firmly long time. Based upon users’ feedback and comparison analysis of other brands, GSM4000 has faster system response speed than its rivals. It could connect to the IP/WIRELESS networks with minimum latency, improving the operation efficiency of the system, and increasing dialing numbers and calling frequency. In addition, SMG4000 also could detect low wireless signals promptly and convert the wireless signals into high definition IP audio and text reliably. Besides, SMG adopts a variety of brand name hardware-components, and its embedded system has been optimized continually in the field, ensuing SMG4000 maintains a better stability under the circumstance of durable high-capacity running.

Moreover, SMG4000 adopts synway`s SUPERFORM EHCO CANCELLATION to optimize the voice quality, and supports all kinds of voice optimization technology ,including CNG,AGC and Adaptive dynamic buffer.  And it also adopts DSP-ENABLED Codecs, including G.711,G.722,G.723,G.729,ILBC, AMR, ect, making the voice performance and processing power unique and being able to satisfy all kinds of applying requirements Under extreme circumstances . In addition, SMG4000 can transfer TEXT information to achieve any expected performance on both voice and data.

SMG4000 Series gateway system adopts carrier-grade system structure. Compared to rival products, its compact size and power consumption are unparalleled. Compatible with different soft switching platforms (IP-PBX, UC), it also adapts open architecture, could be upgraded to fit into specific customer needs. In specific environments, SMG4000 can use and activate multiple SIM cards circularly, improve system security, make full use of bandwidth, and increase ROI.
