  • About the Edition

    This Synthesis Lecture presents a discussion of Quality of Service (QoS) in wireless networks over unlicensed spectrum. The topic is presented from the point of view of protocols for wireless networks (e.g., 802.11) rather than the physical layer point of view usually discussed for cellular networks in the licensed wireless spectrum. A large number of mobile multimedia wireless applications are being deployed over WiFi (IEEE 802.11) and Bluetooth wireless networks and the number will increase in the future as more phones, tablets, and laptops are equipped with these unlicensed spectrum wireless interfaces. Achieving QoS objectives in wireless networks is challenging due to limited wireless resources, wireless nodes interference, wireless shared media, node mobility, and diverse topologies. The author presents the QoS problem as (1) an optimization problem with different constraints coming from the interference, mobility, and wireless resource constraints and (2) an algorithmic problem with fundamental algorithmic functions within wireless resource management and protocols.

      Abstract. LTE unlicensed brings high Quality of Service (QoS) to all mobile users. However, when there are multiple wireless cellular operators trying to access the unlicensed spectrum simultaneously, due to the autonomous behaviors of each operator, it is important yet challenging to avoid malicious competitions among all operators, while guaranteeing the performance of other Author: Huaqing Zhang, Sami Khairy, Lin X. Cai, Zhu Han. The manner in which broadband local access in unlicensed bands and 3G standards in licensed bands may be integrated forms the core of the forthcoming generations of wireless networks. 1G Wireless Standards.

In-Building Wireless Networks and the Emergence of Unlicensed Spectrum Solutions 9 March | Reading Time: 3 minutes For enterprise spaces, in-building wireless (IBW) is an increasingly viable solution to ensure quality indoor as demand increases, so too does RF spectrum requirement. Spectrum management is the process of regulating the use of radio frequencies to promote efficient use and gain a net social benefit.

The term radio spectrum typically refers to the full frequency range from 3 kHz to GHz that may be used for wireless communication. Increasing demand for services such as mobile telephones and many others has required changes in the philosophy of spectrum.

Silver Spring Networks, one of the better-known smart grid firms, uses unlicensed MHz spectrum, and some licensed cellular networks for its smart grid deployments. Eric Dresselhuys, an exec in charge of markets at Silver Spring, tells us the MHz unlicensed spectrum is.

Two of the bands in the spectrum are allocated for use by wireless networks: GHz and 5 GHz. Note that these bands aren’t devoted exclusively to wireless networks. In particular, the GHz band shares its space with cordless phones. As a result, cordless phones can.

Another approach is to use Code Division Multiple Access (CDMA) that subdivides spectrum in a different way, and is used in cellular networks.

The most promising direction for the use of unlicensed spectrum is a proposal by Qualcomm called “LTE Advanced in unlicensed spectrum” (LTE-U), a variation on the LTE system used by 4G smartphones. The key ingredient in wireless networks is "spectrum," the frequencies and airwaves the wireless signals get transmitted over.

Simply put, without spectrum, and enough of it, providers cannot. 2. Network Coverage Spectrum Mobile is a mobile virtual network operator (MVNO) that partners with Verizon to provide its customers with unlimited access to the nation’s largest LTE network.
