In any industry, there is continual progress made towards employee safety and overall process efficiency. Technological advances often help in achieving this goal. Unmanned small aircraft or drones could be considered one of these new tools for wireless network engineering and operations.
Introduction: The smartphone revolution spanning in first two decades of 21st century has changed the way subscribers consume data on mobile devices. The very definition of mobile device has expanded to include tablets, wearables and other connected accessories including machine to machine. With Internet of Things (IoT) being major growth area for data demand, the coverage and capacity requirements of wireless networks will grow for foreseeable future.
Introduction: RF networks have evolved from tower-top and roof-top macro sites to a combination of macro, iDAS/oDAS (indoor/outdoor Distributed Antenna Systems), small cell and hetnets. The prime motivation for this network evolution is for the improvement in network quality demanded by subscribers. The propagation tools used for the initial design of these networks is typically inadequate in modelling and adapting to the evolving networks types deployed.
RF fundamentals for wireless networks begin with proper cell footprint. A cells coverage needs to meet the desired coverage objective and only the objective. RF Shaping is critical to short term performance gains, maximum parameter optimization, and getting the most from costly and limited wireless spectrum. RF Shaping can best be summed into three reasons:
Coverage & Capacity: First consideration for a DAS design is type of venue/building that is the target of DAS deployment. A stadium will have a different requirements & challenges than a high-rise building in terms of number of sectors, coverage & capacity targets. An indoor arena would have to account for different event types to handle variably capacity compared to an airport. These different requirements will be key factor in determining DAS OEM, sectorization, Macro Interaction and DAS Handover zones.
