V. Features of CDMA 2000evdorouter (CDMA 2000 router or evdo router)

1. Three-layer system protection: based on the original two-level software protection + CPU built-in watchdog protection and external Hardware Watchdog protection) system protection, the first-level system monitoring protection SWP is added, it completely solves the industry's "false online", "false dead", and "on-the-fly" and other problems.

2. Complete VPN: fully supports all VPN functions in the industry, including PPTP + MPPE, IPSEC + L2TP, and provides comprehensive security assurance.

3. ultra-large cache: A 32 m data transmission cache can be provided to solve data loss or retransmission caused by network bottlenecks, greatly improving transmission efficiency and reducing customer communication costs.

4. High-speed processing CPU: using an extremely high-speed arm9-level industrial CPU, You can process protocol data conversion at a higher speed to avoid data retransmission and loss caused by slow CPU processing.

5. Memory Management MMU: CPU with memory management MMU can prevent system instability caused by system memory exceptions

6. Real-time Operating System: the new system uses the real-time operating system RTOS to receive and send data more quickly and in real time, avoiding the problem of data packet loss.

7. Complete protocol stack: a complete TCP/IP protocol stack is loaded, with excellent network communication performance.

8. Support for heat da/HSUPA: Support for heat da/HSUPA

9. Excellent EMC performance: powered by V electric shock test, the system is particularly suitable for harsh industrial environments and stable and reliable.
