Indoor mobile coverage is no longer something that is done with a section of four lines in a tender document. Consulting engineering from a client advisor specializing in in-building mobile coverage and emergency radio is a necessity today. I assist in areas such as: - Clarification of needs - Definition of projects/requirements - Preparation of RFQ / RFI - Evaluation of tenders - Follow-up during the implementation phase And why? Indoor mobile coverage is an increasingly complex issue, and it requires a specialist's overview to navigate the area between building developers, operators, suppliers and contractors, in a market where all kind of in-building solutions are pitched and offered. In the competitive market of in-building solutions indoor mobile communications and wireless data access are seen today as basic things - like electricity and water. And users need - and expect - reliable coverage and high bandwidth, regardless of where they are located indoors. In addition, more and more appliances and structural components such as heating and ventilation systems, utility meters, etc. are connected to the Internet and need access to wireless communication (IoT). Seen in the perspective of the constantly increasing use of wireless technology, it is therefore necessary that building developers incorporate mobile coverage and emergency radio from the beginning into new buildings or renovations - in cooperation with the right advisor.
