Seneca Enterprise · Across the UK
Keep the business conversation inside the building. Give tenants and visitors mobile reception in the spaces they use every day.

Energy-efficient glazing, lift cores and basement meeting rooms can interrupt mobile calls. Tenants improvise around the building’s dead spots, leaving the landlord with repeated reception complaints.
Agree the coverage requirement across occupied offices.
Include enclosed rooms where important calls happen.
Assess reception beyond the front desk and entrance.
A shared multi-operator DAS brings commercial mobile service into agreed areas of the property. Seneca coordinates the signal sources, distribution, access and ongoing support so tenants retain their phones and SIMs.
The return for your operation
Keep business calls, verification codes and maintenance updates moving inside the property. Better reception improves the tenant experience and removes a recurring source of IT and property-management complaints.
Receive calls and mobile authentication messages at the desk or in the meeting room.
Provide shared mobile infrastructure that serves the networks selected for the property.
Keep maintenance crews and compatible cellular building sensors in contact.
Build the business case
Tenant partitions, access permissions, repeated floors and basement coverage determine the design.
