Proactive Implementation Stages

How do we design and build a reliable corporate network

Clear engineering cycle: from radio reconnaissance and installation to routing configuration and round-the-clock monitoring.

01

Radio Reconnaissance and Technical Audit of the Object

We go to the location, analyze wall thickness, obstacles, and interference, build a heat map of the Wi-Fi coverage, and evaluate the cabling infrastructure.

02

Topology design and requirements alignment

We are developing connection schemes, calculating the specification of active equipment (routers, switches) and passive materials (cables, patch panels).

03

Installation of cable routes and the server rack

We lay out the twisted pair and fiber optic cable, install 19" rack, perform neat cable management and label each communication line.

04

Configuration of Routing, VLAN and Security

We configure the router, segment the network into virtual subnets (VLAN), close open ports, and raise protected WireGuard/IPsec tunnels.

05

Configuration of fault tolerance and Multi-WAN

Connecting a backup internet provider and a Starlink satellite terminal, configuring automatic failover and QoS priority rules.

06

Load testing and support 24/7

We conduct speed stress tests (iPerf), check seamless Wi-Fi roaming, connect Zabbix sensors, and hand over the network under constant SLA monitoring.

[ FREQUENT QUESTIONS ]

Answers to questions from the client

Key details regarding terms, warranties, transfer of source code and the development process.

We configure the MikroTik router in Multi-WAN Failover mode with regular ping checks (Check Gateway / Netwatch). If the main fiber optic provider's line breaks, the router automatically switches all traffic to the satellite terminal Starlink or the backup provider in less than 1 seconds. Employees in the office even do not notice the disruption — calls and sessions do not drop.
Home routers have weak processors (CPU) and small amounts of RAM. When 15 people open tabs at the same time, connect phones, start video calls and transfer heavy files — a home router overheats, starts losing packets and 'freezes'. Professional equipment MikroTik and UniFi is designed for hundreds of parallel sessions, hardware encryption and operation for years without any reboot.
If several separate routers are standing in the office with the same network name, a smartphone or laptop will keep connecting to the first router's weak signal until the connection is completely lost. Smooth Wi-Fi based on the Ubiquiti UniFi controller supports standards 802.11k/r/v: the controller itself smoothly and unnoticed switches the device to the nearest access point within 20–50 milliseconds, ensuring an ideal connection without pauses.
Segmentation is the foundation of cybersecurity. If all computers, guests with phones, printers, video surveillance cameras and 1C servers are in one general network, any virus encrypting or a guest with an infected laptop can get direct access to the company's internal data bases. VLAN completely isolates traffic: guests see only the internet, cameras are isolated from PCs, and only authorized devices have access to financial databases.
We use exclusively high-quality copper twisted pair cables of Cat.5e, Cat.6 or Cat.6A categories from verified brands (black or non-flammable LSZH insulation). We categorically do not use cheap bimetal (CCA). Each assembled line is tested with a cable tester for integrity, pinout compliance (T568B) and trace length. An official warranty is provided for the completed installation work from 3 to 5 years.
Yes, definitely. By using the modern high-speed WireGuard protocol and our protected cloud relays (VPN Cloud Hubs) in EU data centers, we can connect any number of remote locations even when local providers have grey IP addresses (CGNAT) or the internet works through mobile 4G/LTE modems or Starlink.
