When Should You Reassess?
Redesign the network when coverage, latency, packet loss, VLAN complexity, uplink capacity or expansion into new office/factory areas becomes a constraint.

Network Tools: Buying and Project Decision Guide
A Network Tools project is more than product selection. Capacity, licensing, security, operations and growth should be evaluated together.
Selection Criteria
- User/device density and traffic profile
- Coverage and capacity targets
- PoE, uplink and switch capacity
- VLAN, QoS and security segmentation
- Fiber/copper distance and bandwidth requirements
Doz Teknoloji Project Approach
We start with a site and topology assessment. Where relevant, RF planning, cabling routes, switch/uplink capacity and VLAN design are documented, then validated after deployment.
Frequently Asked Questions
Network Tools: how many access points are required?
AP count should be based on user density, RF conditions, building materials and capacity—not floor area alone.
Network Tools: fiber or copper?
Choose according to distance, bandwidth, electrical environment and future growth.
Network Tools: why are VLANs important?
They logically separate users, devices and services to improve security, performance and manageability.
