The Backhaul Determines
Whether Your SLA Holds or Breaks.

يمكن لنواة 5G ضمان كمون أقل من 5ms. يمكن للراديو توصيل إنتاجية 1Gbps. لكن إذا كانت شبكة النقل بينهما مزدحمة أو ذات خسائر أو غير متاحة — كل شيء يفشل. تصمم HCT شبكات نقل تتوافق مع أداء نظام 5G الذي تحمله.

كل رابط. كل طوبولوجيا. كل مسافة.

HCT engineers transport solutions across all media — fibre, microwave, mmWave, and satellite — with the synchronisation precision and latency budgets that 5G URLLC and MCPTT demand.

eCPRI Fronthaul (تقسيم 7.2x)

Open RAN 7.2x split requires eCPRI fronthaul with <100 microsecond one-way delay and <±65ns time synchronisation (IEEE 1588v2 / SyncE). HCT designs and certifies fronthaul networks between O-DU and O-RU using CPRI-grade fibre or dedicated mmWave links.

رابط خلفي ميكروويف (6-80 غيغاهرتز)

Licenced microwave links for base station backhaul across 1–80km. Full-duplex at 2×1Gbps or 2×10Gbps depending on frequency band. Yemen MTIT spectrum coordination included. Adaptive coding and modulation (ACM) maintains link during rain fade events.

موجات E-Band ملي (70/80 غيغاهرتز)

E-Band microwave delivers 10Gbps+ per channel over 1–5km links — ideal for urban macro backhaul where fibre deployment is impractical. HCT uses E-Band for dense port terminal and campus backhaul where latency must stay under 1ms over the wireless hop.

رابط خلفي VSAT ومدار أرضي منخفض

For offshore oil platforms, desert oilfield sites, and remote government installations beyond microwave range. HCT integrates VSAT (GEO: 600ms RTT) for non-latency-sensitive backhaul and LEO (Starlink, OneWeb: 20-40ms) for sites requiring lower latency satellite paths.

الألياف المظلمة والنقل الضوئي

For high-capacity campus and metro transport, HCT deploys DWDM optical transport on leased or customer-owned dark fibre. 100GbE or 400GbE wavelengths. OTN framing for deterministic latency. OADM ring protection with <50ms restoration on fibre cut.

المزامنة — IEEE 1588v2 / SyncE

5G URLLC and Carrier Aggregation require <±65ns time synchronisation between gNBs. HCT deploys IEEE 1588v2 Precision Time Protocol (PTP) grandmaster clocks with SyncE frequency synchronisation — ensuring all base stations share the same nanosecond time reference.

الأسئلة الشائعة

Why does backhaul determine whether an SLA holds?

The radio network can only deliver what the transport layer carries. If backhaul or fronthaul is under-provisioned or lacks redundancy, latency and availability targets fail regardless of RAN quality. Transport design is therefore engineered against the SLA, not added afterwards.

What transport technologies does HCT Group deploy?

Licensed and unlicensed microwave, E-Band for high-capacity short hops, DWDM for high-capacity optical transport, and fibre. The mix is selected against distance, capacity, latency budget and site access constraints.

When is microwave preferable to fibre?

Where fibre trenching is slow, costly or not permitted, microwave and E-Band deliver high capacity in days rather than months. Fibre remains preferable for very high capacity, long-term core routes. Many deployments use microwave for rapid delivery with fibre following.
