The service provided by microconnect distributed antennas cover a market in heavily populated urban area addressing mobile and radio connection. Also MDA is suited for bustling cities and historical areas where mobile connection and ability is impaired. Having many low power, small antennae preforms and covers an area equal to or better than a traditional Macrocellular site. The centrally located radio base station connects to the antennae by fibre optical cable. Each antenna point contains a 63–65 GHz wireless unit alongside a large memory store providing proxy and

, and the Remote Radio over Fibre (RoF) Unit (Remote Antennae Points). Followed by the Supervisory and Management facilities. This system is compatible GSM (2g and 2.5G) and 3G network requirements of mobile users. The MDA is an economical device that gives a somewhat low-cost solution to give more people access to mobile and broadband connection. This solution also has a low environmental impact that might not clutter up a historical part of an urban area. As communities become more and more dependent on technology solutions like the MDA system is perfect for protecting the natural beauty.
