Good infrastructure starts with good design. SIPPER provides professional network architecture: VLAN design, IP addressing scheme, WiFi site survey and heatmap, PoE budget, QoS policy for VoIP, and complete as-built documentation. VoIP-first thinking in every design.
Most network problems in Thailand, dropped calls, unstable WiFi, slow inter-VLAN routing, and security gaps, come from networks that were never properly designed. SIPPER invests in the design phase before purchasing or installing any equipment.
QoS policy, DSCP marking, voice VLAN, jitter buffer, and codec selection are planned at the design stage from day one.
Most network problems come from missing design. SIPPER invests in the design phase before purchasing equipment.
QoS policy, DSCP marking, voice VLAN, jitter buffer, and codec selection are planned at the design stage. Networks built without VoIP in mind always need rework when phones are added later.
Use RF propagation modeling and walk-test surveys to place APs correctly. Planning accounts for building materials, interference sources, and device density, not just floor area.
Every design engagement includes documentation: logical diagram, physical diagram, IP table, VLAN register, PoE budget sheet, and configuration notes so your IT team can operate the network.
6 core components of a complete network design.
Separate broadcast domains for voice traffic, corporate data, guest internet, and IoT devices. Each VLAN has security policy, inter-VLAN routing rule, and firewall zone. Prevents data broadcast storms from affecting voice.
End-to-end QoS policy: DSCP EF marking for voice RTP, CS3 for SIP signaling, and AF41 for video. Configured on switches, access ports, and firewall interfaces. Tested with real traffic before handover.
Calculate total PoE power draw for IP phones, APs, cameras, and door intercom. Verify switch power supply with 20% headroom. Prevents PoE oversubscription that randomly drops devices.
Measure real signal propagation in the building with spectrum analysis. Identify dead zones, channel interference, and optimal AP placement. Channel plan for 2.4GHz and 5GHz.
Link Aggregation (LACP) for uplinks, Spanning Tree (RSTP/MSTP) to prevent loops, and switch stacking where appropriate. Document redundant paths and test failover.
Structured IP address allocation: separate subnets per VLAN, DHCP scopes with exclusions for static devices, DNS server config, and DHCP relay for inter-VLAN.
Documentation delivered at project end is the reference your IT team needs.
Layer 3 diagram showing VLAN, subnet, routing topology, and firewall zones. Created in draw.io / Visio-compatible format with Layer 1 physical diagram showing rack layout and switch-to-switch cabling.
Complete IP address list: all subnets, static assignments, DHCP ranges, and reserved addresses. VLAN register with VLAN ID, name, subnet, purpose, and firewall zone mapping.
Configuration backups of all devices stored securely. Runbook with step-by-step procedures for common operations: adding a VLAN, adding an AP, replacing a failed switch, and restoring from backup.
