Cost Effective Infrastructure Optimization
As bandwidth demands skyrocket, mobile operators face tough choices, as expensive and constant infrastructure upgrades lower profitability. Moreover, time to market is crucial and reliability is a must especially where it concerns aggregated Point Of Concentration (POC). Availability and quality of microwave transmission links may be degraded due to long distances, noise, climate and other factors, resulting in reduced effective throughputs due to retransmissions. If the operator has two transmission links, and both suffer from poor quality protecting one by using the other, will not solve the problem and packets may still be dropped. Celtro's Virtual Bonding™ addresses these crucial topics by extremely improving the reliability, availability and the quality of the transmission links.
Bonding of Ethernet and E1
Celtro's Virtual Bonding™ binds together different transport links, over different infrastructure technologies, into one optimized virtual backhaul “pipe” for any cellular backhaul transmission. With Virtual Bonding, any combination of existing links, Ethernet or traditional E1s can be combined to form a single high-capacity pipe. This virtual pipe's peak-rate is equal to the accumulated peak-rates of all the individual links put together.
Noise suppression using Self-Learning Error Correction
Celtro's innovative technology of dynamic, adaptive and Self-Learning Error (SLE) correction improves the transmission's quality over legacy noisy E1/SDH links up to BER 10-12. This technology affords several advantages to the operator: it enables IP transmissions of even consumption heavy applications such as IPTV, as well as maximizing the throughput of the link and eliminating retransmission due to noisy or long links. The system automatically recognizes the type and level of noise in the transmission line and applies the appropriate FEC. Thus, the system will "clean" the used line from noise and eliminate the resulting “line errors” in the data link. In fact, if the original level of errors in the line was at BER 10-3 - 10-4, using Celtro’s equipment can reduce the level of errors to as low as BER 10-8 to 10-12.
Protection and bonding
Celtro's Virtual Bonding™ allows the creation of protection and backup between similar or even different types of transmission links. Celtro's Virtual Bonding™ aggregates all incoming transmission links which can be Satellite, fiber or microwave (Ethernet/TDM), to one pipe. Any failure of a transmission link (hardware failure, climate factors, optical cable gap, etc.) will cause an automatic switch of its data to the other functioning links.
Celtro's Virtual Bonding™ can share the load between the Ethernet and the E1 links. Peak data over the E1 will not be dropped by will be directed through the IP link.
- Whenever there are noisy or long lines suffering from poor line quality, Celtro's Virtual Bonding™ will improve the link quality.
- Whenever an operator wants to add IP over Ethernet to his Mobile Backhaul Network without replacing existing infrastructure.
- Whenever an operator wishes to add protection for IP Ethernet and E1s.
- Whenever an operator wants to protect one type of transmission by using another type.
