01

Stay reachable

Address weak indoor signal in the spaces where your team and customers work.

02

Design with evidence

Assess the outdoor donor signal, building layout, materials and operator requirements before selecting equipment.

03

Deliver with confidence

Align the technical scope, applicable approvals, installation and acceptance checks from the start.

FOLLOW THE SIGNAL

A window connection.
Coverage for each floor.

See a floor-by-floor installation concept. Window-mounted donor antennas connect to indoor main units, with mounting and antenna configuration designed for the site.

Three-storey office cutaway: one window-mounted passive panel antenna on each floor, two wall-mounted main units and one ceiling-mounted main unit. No rooftop equipment or separate ceiling domes.ILLUSTRATIVE BUILDING CUTAWAYAUTOMATIC SIGNAL JOURNEY
  1. 01Capture

    Available outdoor signal reaches each floor’s antenna mounted inside the window.

  2. 02Relay

    A concealed connection carries the signal to that floor’s indoor main unit.

  3. 03Boost

    The main unit processes and boosts the selected mobile signals.

  4. 04Indoor coverage

    The system serves indoor workspaces through its configured coverage antenna arrangement.

Simplified signal journey. Dashed lines represent concealed connections. Final server antenna configuration, mounting and performance follow the selected kit, site design and commissioning checks.

THE SIGNAL, EXPLAINED

From the telecom tower
to the people inside.

A closer look at one floor: receive the available outdoor signal, feed the main unit and deliver indoor coverage through the configured antenna arrangement.

Receive. Boost. Connect.
  1. 01Operator tower

    Available 4G LTE and supported 5G signals travel from the operator network toward the building.

  2. 02Window antenna

    The directional donor antenna receives the available outside signal through the window.

  3. 03Main unit

    A concealed coaxial connection feeds GO G43, which processes and boosts the configured operator signals.

  4. 04Indoor coverage

    The configured local server antenna redistributes the boosted signals to indoor phones and workspaces.

Illustrative equipment and signal flow, not measured coverage. Donor and server antenna selection, available 5G bands, cable losses and antenna isolation are established through site design and commissioning.
4G LTE

Everyday mobile connectivity

Extend available LTE signals into indoor areas used by your staff and customers, with the required operator service checked during assessment.

5G DSS / NR

Supported 5G signals

Match the selected GO G43 model and enabled software to the operator frequencies available at the site. 5G support is verified before supply.

UP TO 3 OPERATOR SIGNALS

One coordinated design

GO G43 can handle up to three mobile operator signals within a compatible configuration. BrightGate confirms the proposed operators, bands and antenna plan for your building.

5G support is checked against the selected model, enabled software and operator bands before supply. Coverage and speed depend on the available network, building and commissioned design.

SAUDI REGULATORY & PROJECT READINESS

The right checks.
In the right order.

Our project coordination pathway separates product conformity from customer/site permissions and technical acceptance. It is a delivery framework—not a government application status or a fixed approval timeline.

  1. 01 · Customer & site brief

    Confirm the customer entity, building, site access and target operators. BrightGate coordinates the applicable submission in the customer’s name or CR where the relevant route requires it.

  2. 02 · Device & technical conformity

    Check the exact model, supported bands and available Saudi approval evidence against the applicable CST requirements. Product-family marketing is not a substitute for model-specific evidence.

  3. 03 · Product / import route

    Where applicable, coordinate with the supplier or importer on SASO/SABER conformity and shipment documentation. The route depends on product classification and whether equipment is supplied locally or imported.

  4. 04 · Applicable permissions

    Establish any required device-use, spectrum or operator permissions before activation, and complete the applicable customer submission. The authority or operator decides; BrightGate coordinates the project evidence.

  5. 05 · Installation release

    Confirm the agreed design, applicable approvals and site permissions before installation and commissioning. Record any conditions in the project plan.

  6. 06 · Acceptance & support

    Record commissioning checks, customer acceptance and the agreed support scope. Retain project evidence privately and manage any change in model, location or scope through review.

Official regulatory references

Independent source references. No regulator endorsement or BrightGate accreditation is implied.

CSTOfficial source ↗CST · Equipment requirementsOfficial source ↗SASO / SABEROfficial source ↗Approved-device enquiryOfficial source ↗

CST publishes specific mobile repeater requirements; its telecom bylaw addresses equipment approval. SABER manages applicable product conformity and shipment documentation. The current route, standards, required permissions and responsible applicant are confirmed for each project before commitment.

ONE TEAM. COMPLETE DELIVERY.

From site brief to a supported solution.

01

Survey & design

Survey observations, operator requirements, antenna concept, equipment selection and agreed scope.

02

Coordinate & prepare

Applicable compliance documents, customer submission support, site permissions and installation plan.

03

Install & commission

Antenna and cable installation, equipment setup, signal checks and agreed acceptance testing.

04

Handover & support

As-built information, commissioning record, customer orientation and agreed after-installation support.

Built around your business environment

Offices · Retail premises · Commercial buildings · Customer-facing spaces. Suitability is established through assessment of the building and available outdoor signal.

Your questions, answered.

Will GO G43 support every mobile operator and every 5G band?

No universal compatibility is promised. The exact model, enabled software, bands and operator signals must be checked for the proposed site.

Can BrightGate coordinate registration under our CR?

We support the applicable customer registration or submission under the customer’s CR where the identified route requires it. The required evidence and applicant responsibilities are confirmed before proceeding.

Is this a guaranteed approval process?

No. Authorities and operators determine their own decisions and requirements. Our role is to assess applicability, coordinate evidence and plan delivery around the required permissions.

Does the illustration show a real survey?

No. It explains the design concept only. A project-specific survey and commissioning record establish the real results.

What should I send to get started?

Your city, building use, approximate floor count, required operators and the areas with weak signal. Please avoid sending IDs, credentials or sensitive site details in the public enquiry form.
