Cities are the dynamo of the global economy responsible for the bulk of innovation. Urban planners envisage a 'Digital City' in which ubiquitous broadband wireless and computing enables operations to be more efficient and effective. However, increased use is outstripping energy efficiency improvements leading to unsustainable growth in the energy consumption of wireless access networks. The goal of RF-Cité is to establish the technical viability and environmental sustainability of wireless access deployed at the density necessary to realise a 'Sustainable Digital City' vision. The expected results include extensive simulations of original architectures for the optical transport of RF; for electronic to optical frequency up-conversion; for generating and distributing spectrally pure local oscillator signals in the mm-wave range; and a definitive assessment of analogue versus digital optical transport of RF from an energy consumption perspective. These simulations will be validated by experimental prototyping of key devices and subsystems. The project innovates through its advocacy of coherent optical RF transmission. The research is cutting edge in combining advanced digital signal processing and advanced photonic devices that include ultra-narrow line width single and multi-wavelength continuous wave and mode-locked semiconductor lasers, and planar light circuits for enhanced coherent functionality. The experimental work maximally leverages recent investments in the Photonic Technology Laboratory including an arbitrary waveform generator and advanced optical modulation analyser. The project is important because it aligns with the federal government's priority on Digital Economy. With the majority of its population already living in urban areas, Canada can be in the vanguard to reap the economic and social benefits of the emergence of digital cities, and Canadian enterprises that grasp the commercialisation opportunities generated may reap the benefits of being early to market. Additionally, the project will develop highly qualified and skilled personnel, benefiting from an environment enriched by an industrial and an international dimension, promoting effective knowledge transfer to industry and helping them fill their employment needs.

城市是全球经济的发动机，承担着大部分创新的责任。城市规划者设想了一个“数字城市”，在这个城市中，无处不在的宽带无线和计算使运营更加高效。然而，使用的增加超过了能源效率的提高，导致无线接入网络能源消耗的不可持续增长。rf - cit<e:1>的目标是建立以实现“可持续数字城市”愿景所需的密度部署的无线接入的技术可行性和环境可持续性。预期的结果包括对射频光传输的原始架构的广泛模拟；用于电子到光学频率的上变频；在毫米波范围内产生和分布频谱纯净的本振信号；以及从能耗角度对RF的模拟与数字光传输进行明确评估。这些模拟将通过关键设备和子系统的实验原型进行验证。该项目通过倡导相干光射频传输进行创新。该研究在结合先进的数字信号处理和先进的光子器件方面处于领先地位，包括超窄线宽单波长和多波长连续波和锁模半导体激光器，以及增强相干功能的平面光电路。实验工作最大限度地利用了光子技术实验室最近的投资，包括任意波形发生器和先进的光学调制分析仪。这个项目很重要，因为它与联邦政府对数字经济的优先考虑相一致。由于大多数人口已经生活在城市地区，加拿大可以率先获得数字城市出现的经济和社会效益，而抓住商业化机会的加拿大企业可能会获得提前进入市场的好处。此外，该项目将培养高素质和熟练的人才，使其受益于工业和国际层面丰富的环境，促进向工业的有效知识转移，并帮助他们满足就业需求。
