Benefits of 5G for SD-WAN

Primary WAN Connection

5G performance now rivals or exceeds traditional wired connections:

• Speeds sufficient for most business applications
• Lower latency than many DSL/cable connections
• More consistent performance than 4G
• Faster deployment than fixed-line services

Rapid Deployment

5G enables quick site connectivity without waiting for carrier installation:

• Temporary locations: Pop-up stores, events, construction sites
• Emergency backup: Instant failover connectivity
• Remote sites: Connectivity where fiber is unavailable
• Business continuity: Quick recovery from fixed-line failures

Cost Optimization

5G can reduce WAN costs in several scenarios:

• Replacing expensive MPLS circuits
• Avoiding costly fiber installation in remote areas
• Eliminating diverse path installation fees
• Reducing redundant connection costs

• SLA guarantees: Contractual performance commitments

Bonding Multiple 5G Connections

Technologies like Peplink SpeedFusion can bond multiple 5G connections:

• Combine multiple carriers for redundancy
• Aggregate bandwidth from multiple modems
• Automatic failover between connections
• Load balancing across all available 5G links

Performance Considerations

Real-World 5G Performance

Actual 5G performance varies by location and carrier:

• Urban centers: 200-500 Mbps typical, peaks over 1 Gbps
• Suburban areas: 100-300 Mbps typical
• Regional cities: 50-150 Mbps typical
• Latency: 10-30ms typical, sub-10ms in ideal conditions

Coverage and Availability

5G coverage continues to expand but requires consideration:

• Indoor penetration can be limited, especially with high-frequency 5G
• Building materials impact signal strength
• External antennas may be necessary for optimal performance
• Always plan for 4G fallback in marginal coverage areas

Data Plan Considerations

• 5G data plans typically offer higher allowances than 4G
• Unlimited plans may have fair-use policies
• Business plans offer better terms than consumer options
• Multi-site discounts available from carriers

Security Considerations for 5G SD-WAN

Encryption Requirements

All 5G WAN traffic should be encrypted:

• IPsec tunnels between sites
• TLS for application traffic
• End-to-end encryption for sensitive data
• VPN for remote worker access

5G Security Features

5G networks include enhanced security:

• Stronger encryption algorithms than 4G
• Enhanced authentication mechanisms
• Network slicing provides isolation
• Protection against false base stations

Implementation Strategy

Assessment Phase

Affinity MSP recommends these steps:

1. Evaluate 5G coverage at all site locations
2. Conduct speed and latency testing with all carriers
3. Identify applications that would benefit from 5G
4. Calculate cost comparison with fixed-line alternatives
5. Determine appropriate 5G data plans

Pilot Deployment

• Start with 1-3 sites for proof of concept
• Test performance under real-world conditions
• Evaluate user experience and application performance
• Refine configuration based on results

Full Rollout

• Deploy to additional sites in phases
• Establish monitoring and management procedures
• Train staff on 5G-specific considerations
• Document lessons learned and best practices

Cost-Benefit Analysis

5G Cost Factors

• Hardware: 5G-capable routers ($500-$3000 per site)
• Monthly service: Business 5G plans ($80-$300 per month)
• Installation: Minimal compared to fixed-line
• Management: Included in managed SD-WAN services

ROI Scenarios

5G delivers ROI in various situations:

• Remote sites: Avoid $5K-$20K fiber installation costs
• Temporary locations: Eliminate connection/disconnection fees
• Business continuity: Lower cost than dedicated backup circuits
