iDirect based Internet Services
iDirect's satellite-based IP communication technology enables constant connectivity for voice, video and data applications in diverse and challenging environments. These include extending private networks to remote offices, supporting mobile connectivity across land, sea and air, providing rural telephony and Internet broadband and maintaining communication in the wake of disasters and network failures. In terms of performance, almost all up- and downstream speeds are supported. The standard is also supported for mobile systems.
The iDirect Intelligent Platform™ integrates advanced technology into iDirect’s portfolio of hubs, routers and network management software to address the growing complexity of deploying and managing global IP networks. iDirect serves customers in 50 countries through a diverse network of channel partners, including some of the largest satellite providers, operators and
carriers in the world and seven of the World Teleport Association’s Global Top Ten. Headquartered in Herndon, Virginia, iDirect has offices in Europe, Asia, Middle East, Africa and Latin America.
DCB-RCS based Internet Services
DVB-RCS is the future standard in 2-way satellite business. Once you follow this standard, you may use your equipment on several satellites. Only LNB or BUC might need to be changed. DVB-RCS is supported by several satellite organisations like Eutelsat and several small satellite Hub operators. We offer this service for stationary and mobile as well as for maritime use on many satellites. Expect more DVB-RCS satellites to be available in future.
Gilat based Internet Services
Gilat is the proprietary service run by Gilat, who is one of the market leaders in satellite modems. Gilat is partly owned by Astra Satellites in Luxemburg and Alcatel. As part of this family is also Gilat, Satlynx a Astra and Alcatel company uses the Gilat hardware. This standard is also supported by Intelsat, the worlds largest satellite operator and is available on several satellites. Interchange between provider or satellite is not possible, as the system uses unique keys. Many hub operators in Africa use this technology to provide services.
We do not have Gilat products, as the service can only be recommended for home and SOHO users. Gilat based services are retailed via a large number of mainstream ISPs and big telecommunication organisations. Often this technology is used by the "big ones" in the industry. A VoIP system is not available. VPN was never proven to be working.
Direcway based Internet Services
Direcway is one of the most widely spread 2-way satellite system in the market. The service is proprietary and available on several satellites. Interchange between providers or satellites is not possible, as the system uses unique software keys.
Level421 recommended DIRECWAY services for a long time, as they are consumer, sometimes SOHO oriented products at a quite low price in 2-way technology and are quite easy to install and set up. The perfect start system into the 2-way satellite world. Unfortunately DIRECWAY services show deficites in the upstream and due to the proprietary standard, it is very difficult for the customer to change his provider without throwing away his modem. As the hub technology has a quite restrictive FAP engine, which limits all users, who need high data volume, the solution is quite inflexible when it comes to extending. Individual services, or add on services, like mobile or VPN are not possible.
The biggest problem is the non defined contention ratio and thus the unknown quality of service. Instead of categories of service, a so called SAR is defined which assumes that only 1 of 4 users are online at the same time. In reality this means that a SAR of 1:30 can easily develop into a 1:120 contention ratio. So in theory 120 users can share one link, basically not leaving any space for individual user service.
