Not all networks are created equal.

A customer wants a complete solution including Wi-Fi, cameras, network, telephony and fax as well as all the usual office IT equipment.

The client received several proposals from different suppliers that did not meet its expectations. The customer has high ceilings in some places for floor areas that need to be covered with Wi-Fi.

Height usually achievable with lifts. Requiring a complete move and a shutdown of the customer's operations.

The number of devices to be powered by Power over Ethernet is consequent.

The cabling coverage offered by suppliers and others made quotes expensive.

Therefore a solution with serial wiring was proposed.

This type of cabling allows the distribution of Power over Ethernet through a single RJ45 cable to multiple devices.

Advantages of the solution.


• Cheaper wiring
• Fewer network switches to provide
• Cheaper UPS (Uninterruptible Power Supply)
• Reduced customer electricity bills
• Less expensive maintenance
• Network provided at half the cost
• Lifetime Warranty with Upgrade
• No licenses to renew
• Lighter wiring on the structure

Wiring optimization.

As usual, the audio quality has been given top priority in the Voice over WLAN network design.

The network with low latency and jitter is optimized for voice (WMM-PS: Vo/Vi).

The type of Wi-Fi network meets the requirements of the best wireless phone manufacturer.

The customer also wants continuity of service in the event of a power outage.

WiFi Phone.

Continuity of service includes making calls through the PSTN (Public Switched Telephone Network) when there is no electricity outside.

The UPS and then the customer's generator guarantees continuity of service.

The budget freed up allows the customer to add a backup connection via the mobile data network.

In addition, all critical equipment is duplicated.
