As satellite operators, service providers, and enterprises evolve their connectivity strategies, two paramount needs arise: intelligent traffic optimization and wideband throughput. SatHarbor addresses these with the CEL-231 Series and CEL-232 Series, each tailored to distinct but complementary challenges in modern VSAT networks. Whether you require advanced 2G/3G/LTE cellular backhaul or efficient aggregation of large HTS transponders, these platforms excel at delivering robust performance, low latency, and flexible network topologies.

CEL-231 Series: Intelligent Satellite Router

1. Embedded Computer for Cellular Backhaul & Optimization

   • Incorporates an Intel® Celeron-based embedded computer that can run advanced backhaul optimization, GTP decoding, TCP acceleration, or other custom software—perfect for 2G/3G/LTE networks.

   • Streamlines M2M/IoT deployments by collecting and processing data locally before sending it over the satellite link, reducing bandwidth consumption.

2. Multi-Demodulators & Universal Modulator

   • Two DVB-S2/S2X demodulators (up to 500 Msps) plus a 4-channel MF-TDMA demodulator let you operate star, mesh, or SCPC topologies simultaneously.

   • A single SCPC/TDMA modulator can switch on the fly between burst (TDMA) and continuous (SCPC) modes for maximum efficiency.

3. High IP Throughput & Low Latency

   • Processes up to 190,000 IP PPS, with ultra-low round-trip delay (~570 ms) in TDMA mode—ideal for time-sensitive traffic like voice, video, or critical sensor data.

   • Features advanced QoS, VLAN, DSCP, bridging/routing, and AES-256 security for mission-critical networks.

4. Versatile Deployment & Management

   • Housed in a 1U rackmount chassis with built-in AC power (optional -48 VDC input), suitable for data centers or remote sites.

   • Supports 1:1 or M:N redundancy, minimal power draw (~48 W max), and quick boot from alternative energy sources (e.g. solar).

CEL-232 Series: Wideband Satellite Router

1. High-Capacity DVB-S2/S2X Modulator

   • Supports symbol rates up to 200 Msps and wideband carriers up to 240 MHz, achieving data rates of up to 650 Mbps on the outbound.

   • Ideal for HTS (High Throughput Satellite) transponders, allowing multiple sub-networks or SCPC channels to share a single wideband carrier.

2. HUBMUX Feature for Aggregation

   • Time-Slicing DVB-S2X standard merges TDM/TDMA hubs or SCPC links into one large carrier, enabling multiple services to run under full isolation while optimizing satellite resources.

   • Perfect for multi-VNO environments, letting separate networks or applications co-exist in a single wideband downlink.

3. Multi-Topology & Multi-Beam

   • Two DVB-S2X demodulators (up to 500 Msps) plus a four-channel MF-TDMA demodulator provide flexible inbound handling.

   • Designed as a core wideband modulator for large HTS hubs, bridging B2C, B2B, and B2G services into a unified transponder.

4. Advanced IP Routing & Low Power

   • Over 190,000 PPS, IPv4/IPv6, QoS, VLAN, bridging, and acceleration ensure end-to-end network performance.

   • Consumes only 15 W typical, far below comparable systems—simplifying deployment and lowering OPEX.

Key Benefits & Use Cases

• Cellular Backhaul (2G/3G/LTE): CEL-231’s embedded optimization can slash bandwidth costs and improve user experience, especially in remote or underdeveloped areas.

• Maritime & Offshore: Both series’ multi-mode operation and minimal power usage let maritime vessels dynamically switch from SCPC to TDMA as traffic demands shift.

• Enterprise WAN & ISP: CEL-232’s wideband modulator or CEL-231’s embedded compute can unify large corporate networks, broadband services, or specialized SCPC links under a single hub infrastructure.

• Government & Military: Rely on advanced encryption (AES-256), multi-level QoS, and swift configuration changes to adapt to dynamic security and throughput requirements.

Best Practices & Considerations

• Maximize ROI with ACM & Hub Features: Both series support Adaptive Coding & Modulation on forward and return channels, plus advanced hub controller capabilities that help use satellite capacity efficiently.

• Combine TDM, TDMA & SCPC: Converge real-time voice or bursty M2M traffic on a shared TDM/TDMA network, while dedicating SCPC channels to high-volume data streams.

• Choose the Right Model: CEL-231 is best for backhaul optimization or specialized on-site data processing, while CEL-232 addresses wideband HTS demands with slicing and multi-service aggregation.

• Plan Redundancy & Scalability: For mission-critical networks, consider 1:1 or M:N setups to ensure minimal downtime and easy expansions as bandwidth demands grow.
