Complete Information for OCENS Mail The reason OCENS Mail works as well as it does is because the technology used in the program is optimized specifically for E-Mail transfers. Many of our competitors offer compression technologies that fail to perform as well as ours simply because they blindly compress everything that comes over the line. OCENS Mail concentrates on optimizing only E-Mail transfers and it does a superb job at this. All wireless technologies are basically simplex in the nature of their radio transmissions. This means that when one radio (or sat phone) is transmitting data the full band width of the channel is allocated for the one way transfer. It takes a lot of protocol overhead and therefore time to reverse the direction of the communication channel. This basic design feature of all wireless devices is counter productive when looking at E-Mail transfers. The SMTP (Simple Mail Transfer Protocol) protocol that all standard E-Mail programs use defines a "chat" that requires about 10 line turn arounds to complete. That is 10 times that the direction of data transmission must be reversed to complete the transaction. This "chat" kills the performance for sending mail via these channels. Companies that concentrate only on compressing data and not limiting the number of line turn arounds gain very little performance advantage when doing e-mail traffic. OCENS Mail is designed specifically to reduce the number of line turn arounds while additionally benefiting from compression. The proprietary E-Mail protocol eliminates ALL line turn arounds by sending large compressed streams of data to a server process running at our central location. The server unpacks the data stream and then carries out the standard SMTP "chat" to send the mail. Receiving mail uses the same wireless enhanced technology. All incoming mail is collected by the server packaged into one compressed stream of data which is send to the e-mail client in one unidirectional transfer. The E-Mail client then parses through the data breaking it up into individual mail messages and then presents them to you for viewing. What does all this mean? Well it means that on average OCENS Mail is about 20 to 25 times faster than our competition when it comes to delivering E-Mail. For example, receive over 20 e-mails in less than 1 minute over a Globalstar phone. The E-Mail transfers "cook"!
