Bluetooth-based radio access with asymmetric processing

医院需要无线网络，以便可靠地访问/传输信息到/从护理地点，使医疗保健专业人员能够更快地做出决定和诊断。在仓库、家庭、办公室等场所，需要对信息、产品和文档进行分发和跟踪。本项目的目标是开发一个具有集中处理和分布式接入点的非对称无线网络实验系统，为微微小区(房间群等)提供无线服务。使用蓝牙设备和传感器。接入点配备了多个天线(MIMO)，并通过光纤或电缆连接到处理中心。接入点是通用的(非特定于标准的)，因此使网络能够支持其他标准，如IEEE 802.xx。反向链路上的信号在接入点被下变频、放大和采样，并被传输到处理中心，在那里根据信号格式或标准完成大部分处理。在前向链路上，在处理中心生成诸如调制、纠错编码、空时编码、波束成形、加密等信令格式，并将其发送到接入点。光纤或电缆提供进出接入点的数据传输所需的宽带。这种不对称的配置提供了大量机会。接入点不需要随着标准的发展而更换。在处理能力要求、信号格式或天线重新配置和安全处理方面具有更大的灵活性。因此，试验台对于多标准操作和测试新标准和算法是有用的。新的、低复杂度、低功耗的MIMO处理算法将被开发出来，以提高传输速率、与其他无线系统的共存和用户容量。这些解决方案将导致局域网/个人局域网和多标准接入点的新设计，这将对加拿大医疗保健专业人员处理和共享患者信息以实现快速诊断和治疗等方面产生重大影响。其他将受益的加拿大服务包括仓库、办公室、学校等。

Hospitals are demanding Wireless networks in order to reliably access/transfer information to/from the point-of-care, allowing healthcare professionals to make faster decisions and diagnosis. In warehouses, homes, office, etc., information, products and documents need to be distributed and tracked. The objective of this project is to develop an asymmetric wireless network experimental system with centralized processing and distributed access points that provide wireless service to picocells (cluster of room, etc.) using Bluetooth devices and sensors. Access points are fitted with multiple antennas (MIMO) and are connected to the processing centre via optical fibers or cables. The access points are generic (non-standard specific) and therefore enables the network to support other standards such as IEEE 802.xx. Signals on the reverse links are down converted, amplified and sampled at the access point, and transmitted to the processing centre where the bulk of the processing is done according to signal format or standard. On the forward link, signalling format such as modulation, error correction coding, space time coding, beamforming, encryption, etc. are generated at the processing centre and transmitted to the access points. Optical fibers or cables provide the wide bandwidth required for data transfer to/from the access point. This asymmetric configuration provides numerous opportunities. The access points need not be replaced as standards evolve. There is more flexibility with respect to processing power requirement, ease of signal format or antenna reconfiguration and security processing. The test bed is, therefore, useful for multi-standard operation and for testing new standards and algorithms. Novel, low complexity, low power MIMO processing algorithms will be developed to improve transmission rate, co-existence with other wireless systems and user capacity. These solutions will lead to a new design of local/personal area networks and multi-standard access points that will significantly impact, for example, how Canadian healthcare professionals handle and share patient inormation for speedy diagnosis and treatment. Other Canadian services that will benefit are warehouses, offices, schools etc.
