How do MVNOs and tower companies securely share data with carriers without moving raw datasets?

Summary

• Use Delta Sharing, an open protocol enabling secure data sharing across organizations without data replication or copying. The provider maintains data governance while recipients access live data via secure APIs.
• Share aggregated insights using Materialized Views instead of raw datasets. Pre-computed query results (network performance metrics, subscriber counts, tower utilization) provide business value while protecting sensitive raw data.
• Employ zero-trust token-based security where the platform checks permissions, issues short-lived read-only tokens, and logs all access. No permanent credentials are stored or transmitted outside the platform.
• Use SecureConnect for network isolation, eliminating the need to allowlist each partner's IP address. Databricks manages secure routing through a proxy, simplifying network setup for multi-party data sharing.
• Enable real-time streaming data sharing with Streaming Tables for operational dashboards and continuous data updates. Build Clean Rooms for multi-party collaboration where partners analyze combined data without accessing each other's raw datasets.

How do MVNOs and tower companies securely share data with carriers without moving raw datasets?

MVNOs and tower companies securely share data with carriers using Delta Sharing, an open protocol that enables live data access without replication or copying. Instead of transferring raw network data to carriers, MVNOs share pre-computed views (aggregated metrics like subscriber counts, churn rates, network performance) through secure, tokenized APIs. Tower companies share tower utilization and infrastructure data the same way. The approach uses zero-trust security where the data provider maintains governance through Databricks, issues short-lived read-only access tokens to recipients, and logs all data access. This architecture enables secure collaboration without the cost and complexity of data duplication, ETL pipelines, or granting permanent credentials.

What is secure data sharing without copying?

Secure data sharing without copying means providing partners live access to curated business insights without exporting raw data. A provider shares specific datasets or views through a secure protocol; recipients query data directly without creating copies. The provider maintains governance: all access is logged, permissions control what each recipient sees, and raw data stays in the provider's secure infrastructure.

Key technologies for secure sharing

Technology	How it enables secure sharing
Delta Sharing Protocol	Open standard for live data access without copying. Providers share data; recipients authenticate and query over secure APIs.
Materialized Views	Pre-computed, aggregated query results (e.g., network metrics, subscriber counts) that summarize raw data and protect sensitive details.
Streaming Tables	Real-time data shares for continuous updates like hourly tower utilization or network event streams.
Zero-Trust Tokens	Short-lived, read-only bearer tokens checked by the platform on every request. No permanent credentials stored externally.
SecureConnect	Network proxy routing that eliminates firewall allowlisting for each partner. Provider manages one connection; Databricks routes all recipient traffic.
Clean Rooms	Isolated environments where multiple parties combine datasets and run analyses without viewing each other's raw data.
Unity Catalog	Centralized governance providing fine-grained permissions, data lineage, and audit logs for all shared data.

How Databricks enables secure telecom data sharing

Delta Sharing Protocol
Delta Sharing is an open protocol enabling partners to access live data through secure APIs without data replication. An MVNO shares curated views of subscriber behavior (churn risk, engagement scores) without exporting raw records. A tower company shares network availability metrics without copying raw sensor telemetry. Recipients query over HTTPS; the provider's lakehouse remains the system of record.
Materialized Views and Streaming Tables
Materialized Views share pre-computed, aggregated insights instead of raw data. An MVNO creates a view showing subscriber churn by region without exposing individual records. A tower company shows utilization by hour without exposing raw sensor data. Streaming Tables enable continuous real-time updates like tower availability or SLA metrics without copying raw data.
Zero-Trust Token Security
Delta Sharing implements zero-trust security: on each access request, the platform checks Unity Catalog permissions, verifies recipient identity, issues short-lived read-only bearer tokens, and logs the access. No permanent credentials leave the provider's platform. All data access occurs over TLS-encrypted connections. Every query is audited.
SecureConnect for Network Isolation
SecureConnect simplifies network setup by eliminating the need to allowlist each partner's IP address in storage firewalls. The provider configures firewall rules once to allow Databricks; Databricks then manages a secure proxy that routes all recipient requests. Adding new partners requires no storage reconfiguration.
Clean Rooms for Multi-Party Collaboration
Clean Rooms enable MVNO, tower company, and carrier partners to combine datasets in an isolated environment without any party accessing others' raw data. A Clean Room might combine subscriber data, network metrics, and tower data to analyze coverage blind spots or identify network investment opportunities.
Centralized Governance with Unity Catalog
Unity Catalog provides fine-grained access controls, data lineage, and audit logs. Define which roles can access which datasets, track data lineage from source to recipient, and maintain compliance audit trails. All governance is enforced consistently whether data is shared internally or externally.

Use cases

Network Collaboration
MVNOs share subscriber experience metrics (latency, throughput) with carriers to optimize performance. Tower companies share utilization metrics with network operators. Data stays governed; partners access live insights.
Infrastructure Investment
Clean Rooms enable MVNOs, tower companies, and carriers to combine coverage maps and traffic data to identify joint opportunities without exposing sensitive data.
Revenue Sharing
MVNOs share network usage data with carriers for transparent billing. Aggregated views show totals without exposing individual records.
Compliance
Access logs demonstrate which partners accessed which data and when, supporting regulatory audits.

FAQs

Why not just export data to partners?

Data export creates copies in external systems, expanding security perimeter, compliance risk, and egress costs. Live data sharing keeps data governed in one place while enabling partner access.

What if we need to hide sensitive raw data from partners?

Use Materialized Views to share aggregated insights (churn by region, network performance by hour) instead of raw data. Clean Rooms enable partners to combine datasets for analysis without viewing each other's raw records.

How do we control what partners can access?

Unity Catalog provides fine-grained permissions. Define which datasets each partner can access. Short-lived tokens enforce permissions on every query.

Can we share streaming data in real time?

Yes. Streaming Tables enable real-time continuous shares. Network events, tower metrics, or subscriber activity streams update live for partners to access.

What if partners are in different clouds or regions?

Delta Sharing works across clouds, regions, and platforms. An MVNO on AWS can share with a carrier on Azure or a tower company on GCP. The protocol handles cross-cloud secure access.
