EVDO?

Currently, I'm involved in this project too.

What is EVDO? Just the Basics:

>EV-DO - Evolution Data Optimized

>Personal broadband wireless service for a wide range of customers, from business people to students

>Always on - - similar to DSL (wherever 3G capability is available)

>Rides on CDMA signal- 1x data capability available everywhere CDMA voice service available

>Up to 10 times the peak data rate of the next best public wireless solution - 800 - 1,000 Kbps (kilobits per second) average download speeds, comparable to DSL speeds

>Allows the user to be connected wherever they are are not only for email, but for downloads, large files, photos, spreadsheets, etc.

>Advantages over WiFi:
>>Always on with seamless roaming!
>>Signal can travel on same cell sites as cell phones
>>No 300-ft range from the cell tower or "hotspot"
>>Customers can access their corporate VPN (virtual private network) anywhere they can get a cellular signal via a secure, encrypted signal
>>Can download and run video clips in real time
>>Can provide service to customers outside of cable-modem or DSL areas

>Relatively low cost with high capacity - allows rich web browsing and application usage

>1xRTT: 50Kbps - 100Kbps Upload and Download (bursts to 144Kbps)

>EVDO Rev 0: 400kbps-1000kbps Download (bursts up to 2.0Mbps), 50kbps-100kbps Upload (bursts to 144Kbps)

>EVDO Rev A: 600Kbps-1,400Kbps Download (bursts to 3.1Mbps), 500Kbps-800Kbps Upload (bursts to 1.8Mbps)

IPVPN access via VSAT

Hi to all

Long time no updates. Currently I'm involved designing VSAT as alternative access to IPVPN network. There are two VSATs available ie VSAT C-band and VSAT Ku-band. Both have their own strength.

I will update my design later, soooon.
