    Hours, days, weeks, months, it varies because of many variables are involved.

    The radius also varies because of the many variables involved.

     

     

    aka: It depends.

    Good questions. But neither have a definitive answer.

     

    Sprint has three different OEM's managing the deployment with their equipment. Alcatel Lucent, Samsung and Ericsson. Each OEM has hired dozens of subcontractors. All these different companies working with different equipment in different climates/weather and different people who work at different speeds. And each site is unique, some are harder than others. Then there could be inspection and bureaucratic delays. Backhaul problems. Provisioning issues.

     

    So we have seen that most sites take between 3 weeks and 3 months from start to finish. We had one site in New Orleans that appeared to finish in one week. We also have had one site start 9 months ago in Kansas and now finishing up. So there is a lot of variability.

     

    As for how far an LTE signal can reach...it is also highly variable. In Sprint deployments it can be as little as a few blocks in a dense urban environment, or as much as 10 miles in a flat rural area outdoors.

     

    Cell sizes are engineered precisely. RF Engineers design each LTE signal to propagate a certain distance for maximum benefit. They adjust transmission power and panel downtilt accordingly. They cannot extend the signal as far as possible where it interferes with other Sprint sites broadcasting on the same channel. Each site can only overlap the next sites signal by a little bit.

     

    In denser city and suburban locations, if they allowed the signal to broadcast as far as possible, it would reach over the adjacent two or three sites in each direction and cause severe interference. The LTE performance would plummet as a result. So these cells are designed to be much, much smaller. Rural LTE sites on boomers can be hundreds of square miles in coverage though.

    I Thank you both for answering my questions.
