A mobile phone is one of the means used by people to communicate with each other on a daily basis. Accordingly, the implementation of cell phone coverage should be such that the coverage is complete for all parts of the building. Therefore, based on the latest technologies in the world, the company can design different systems, which include the following technologies:

1. Smart cells
2. ACTIVE DAS system
3. PASSIVE DAS system
4. MULTI DAS system

The lack of need to separate antennas for each operator and the possibility to use a centralized system for all existing operators are among the benefits of DAS systems.

In-building penetration
You have ample coverage outside your house/office and have poor reception indoors - it's probably a clear indication that the building itself may be the culprit.
Dense or metal-based building materials can reflect or absorb RF signals, reducing the level of signal that reaches indoors.
Unfortunately, during building construction, indoor coverage is rarely considered - in fact materials that insulate best and provide most structural strength are typically the worst offenders for reducing indoor coverage.
These materials can include:
• window insulation/tinting
• foil-based roof insulation
• metal roofing (e.g. Color bond)
• concrete & brick
• metal support structures
• large metallic surfaces (e.g. Garage Roller Doors)
• copper plumbing & wiring.
