3G HSDPA Router for Wireless M2m

Nowadays, more and more industrial field of data transmission requires wireless connection. We called it as Wireless M2M solutions.
For wireless M2M solution, HSDPA router is a kind of 3G router.
3G router covers 3g hsdpa router, 3g hsupa router, 3g evdo router and 3g td-scdma router. The most popular is the hsdpa router.
HSDPA router can reach 7.2mbps downlink speed, which is suitable for huge data transmission in wireless m2m solutions, such as live video monitor control applications.
Normally the HSDPA router provides at least LAN RJ45 port for the remote device. The HSDPA router connects to the internet by hsdpa networks using a sim card. This build a wireless hsdpa connection for the remote devices.
For the HSDPA router, there are industrial class and non-industrial class.
The industrial class hsdpa router are right for industrial wireless m2m. Such as power control, water schedule, traffic, oil field, weather forecast, environmental protection, street lamp control, post, bank and many other areas.
The industrial HSDPA router provides the user a point to point or point to multipoint communications link in a single compact and resilient unit.
Normal the industrial HSDPA router support the following mail features:
PPTP and IPSEC VPN Client: Offering the ability to add a fixed IP address to the device by connecting through a companies private network.
Browser configurable software, giving ease of set up from any P.C.
Supports SNMP
High Speed Circuit Switched Data (HSCSD) or PAD mode via the serial port 
Diagnostic log viewer via browser
Always online
Remote web control. (GUI)
Industrial HSDPA routers allows users to connect up to one or four to five Ethernet devices to cellular hsdpa networks, and provides secure cellular GSM/GPRS or UMTS/HSDPA connections for reliable primary and backup network connectivity to industrial automation devices.
The industrial HSDPA routers come with complete routing and network protocols to allow you to connect remote LANs and remote Ethernet devices to cellular hsdpa networks.
And the non-industrial class hsdpa router are for normal personal internet browsing connections.
The HSDPA router provides wifi also, nowadays the newest technology is 802.11n, which provides max 300Mbps speed.
As the industrial hsdpa router of wireless m2m applications, normally it provides for the following:

Remote Data Monitor and Control
