RETICE — Energy and ICT Network for Education and Enterprises
RENAL — Energy and Digital Networks for Local Autonomy · SMART LoCan-80/20
Two complementary technologies deployed by RETICEO to bring renewable energy and connectivity to education for everyone, everywhere — 100% autonomous, no Internet, no telecom operator. Continuity of education in-person and remotely, in real time.
RETICE + RENAL-SMART Architecture
RETICEO deploys a two-tier approach: RETICE provides complete high-speed connectivity within each school, while RENAL-SMART 80/20 extends this connectivity across a city, region or entire country — all without Internet and without a telecom operator.
Energy and ICT Network for Education and Enterprises
High-speed network infrastructure deployed within the school perimeter — covering 100% of connectivity needs on-site, without Internet or any telecom operator.
RETICE is the local digital network deployed at the heart of each school by RETICEO. It forms the local digital backbone — an autonomous high-speed network covering the entire school campus.
Energy and Digital Networks for Local Autonomy
SMART LoCan-80/20 : Smart Local Cloud and Area Network
Wide-coverage connectivity — from 5 to 40 km radius, scalable to full city, region and country coverage. Ultra-high-speed, hyper-secured, no Internet, no telecom operator.
RENAL-SMART 80/20 brings Ultra High-Speed connectivity over 5 to 40 km radius, scalable to full coverage. It enables continuity of education in-person and/or remotely in real time, WITHOUT INTERNET.
RENAL-SMART 80/20 deploys progressively from each RETICE school toward complete territorial coverage. Each level adds an autonomous THD connectivity layer, never requiring Internet or a telecom operator.
RETICE covers 100% of the school perimeter — all classrooms, administration, common areas. The RETICE hub is the anchor point for the entire infrastructure.
RETICERENAL-SMART 80/20 connects all schools in a city via a private THD network. Students can follow lessons from home in real time, without Internet.
RENAL-SMART 80/20Progressive extension to full regional then national coverage. Guaranteed educational continuity everywhere — rural, remote, no telecom network.
Extended RENAL-SMART 80/20The will to use digital technology in education is clear, but energy and digital divides block access. RETICEO delivers the integrated answer.
Lack of stable electricity and network infrastructure in rural and peri-urban areas — frequent power cuts blocking any digital pedagogical continuity. Innovations in educational use remain insufficient without reliable energy.
Conventional solutions depend on Internet and telecom operators — prohibitive costs, unpredictable availability, no data protection. In rural areas, this dependency makes any digitalisation illusory.
Existing solutions do not enable educational continuity between school and students' homes. No extended connectivity = no remote lessons, no follow-up outside the school perimeter.
RETICE provides 100% of connectivity needs within each school — high-speed local network, Smart Local Cloud, autonomous CeRSER energy and ZEP-X terminals — without Internet, without telecom.
RENAL-SMART 80/20 extends connectivity up to 40 km radius, covering an entire city, region or country. Students remain connected to their school from home, in real time, without Internet or telecom.
This unique combination enables for the first time to replicate all the activities and interactions of an in-person class remotely, in real time, without Internet or telecom — anywhere in the territory.
RETICE deploys an integrated infrastructure of 3 complementary components in each school — autonomous renewable energy, local high-speed connectivity and a national educational cloud.
The CeRSER energy module provides autonomous power for the entire RETICE system — solar panels, storage batteries, charge controller. Zero dependency on the national power grid.
The RETICE local THD network covers 100% of the school — intra-campus fibre, high-density Wi-Fi in every classroom, administration, common areas. No Internet required, no telecom operator.
The Smart Local Cloud is the school's local mini-datacenter — servers hosting the KA SOFT LMS, pedagogical content, RETICEO EXAM, student data. Entirely local, under complete control of the school.
RENAL-SMART 80/20 is the natural evolution of RETICE toward wide-coverage connectivity. Its full name — SMART LoCan-80/20 — stands for Smart Local Cloud and Area Network: an extended local area network, secured and hyper-protected.
RENAL-SMART LoCan-80/20 Architecture
RENAL-SMART 80/20 is the evolution of RETICE toward large scale. While RETICE radiates within the school perimeter, RENAL-SMART 80/20 extends that network over 5 to 40 km radius, connecting all schools in a zone in a secure private THD network.
The 80/20 ratio reflects the deployment philosophy: 80% of pedagogical needs are covered locally by RETICE in each school, and 20% are handled via the extended RENAL-SMART network — national synchronisation, inter-school lessons, centralised exams. Together, they cover 100% of educational needs, without Internet.
The RETICE + RENAL-SMART architecture is organised into 3 complementary levels, from the student's terminal to the national datacenter — all without Internet or telecom operator.
Unlike conventional approaches that depend on Internet at every level, RETICEO's architecture is 100% autonomous at each tier:
An objective comparison on the criteria that matter for tomorrow's digital education.
| Criterion | Conventional approach (Internet) | RETICE (school) | RETICE + RENAL-SMART 80/20 |
|---|---|---|---|
| Internet dependency | 100% dependent | 0% — Zero Internet | 0% — Zero Internet |
| Geographic coverage | Areas covered by an operator | School perimeter only | School → City → Region → Country |
| Remote lessons | Yes (if Internet available) | No — school perimeter only | Yes, real-time, without Internet |
| Telecom operator required | Yes — recurring costs | No — autonomous | No — autonomous |
| Data sovereignty | Foreign servers | Local AES-256 | National + local AES-256 |
| Rural / remote areas | Not covered | Yes — autonomous RETICE | Yes — RETICE + RENAL mesh |
| Continuity during outage | Total shutdown | Continues locally | Continues — RETICE + RENAL |

The RETICE Digital Classroom is the integrated lesson management environment natively connected to the RETICE / RENAL-SMART infrastructure. The teacher manages their lesson, evaluates in real time, assists each student and supervises the entire class from a single dashboard — 100% on the local network, without Internet or external cloud.
From their ZEP-X terminal, the teacher accesses all orchestration tools: broadcasting teaching materials, launching assessments, remote control of a student's terminal, instant messaging, automated roll call and application management. The mosaic view enables real-time supervision of each learner's screen — with minimal latency thanks to the RENAL-SMART local network.
