Office Building Cell Signal
Consistent voice and data across meeting rooms and workstations.
Application Overview
Office building cell signal is often weak behind Low-E glass and dense partitions. A passive DAS with a roof donor and zone antennas keeps voice and data usable in meeting rooms, workstations and the lobby. The design balances capacity and coverage by zone, not by adding more power to one host.
Typical Installation Layout
A typical installation uses an outdoor donor antenna, a booster or fiber repeater, a distribution network and indoor service antennas.
- 1
Survey the outdoor donor signal and identify a suitable roof or facade antenna position.
- 2
Install the booster in a ventilated technical room and connect the donor antenna.
- 3
Distribute signal through ceiling antennas on each floor, using splitters and couplers.
Installation notes
- Plan antenna positions on the floor plan before cabling.
- Use a balanced number of antennas per branch to avoid large level differences.
- Consider a fiber repeater when the building has multiple wings or long cable runs.

Frequently Asked Questions
How many indoor antennas does an office floor need?
It depends on floor area, partition density and output power. A common starting point is one ceiling antenna per 80–150 m² in partitioned offices, confirmed by a site survey.
Can the system cover multiple operators?
Yes. Select a dual-band or tri-band host with the operator bands used in your area. Frequency combinations are configured to order.
Will installation disrupt office operations?
Most cabling and antenna installation can be scheduled outside business hours. The booster itself is wall-mounted and requires only a power outlet and cable routes.
Can we use the same system for a future expansion?
Leave spare ports on splitters and reserve cable routes where possible. A larger host or an additional remote unit can be added later.
