Yesterday the UK communications regulator Ofcom published final regulations for a forthcoming mmWave spectrum auction in the 26 GHz and 40 GHz bands. The approach balances competitive allocation in high density areas with first come, first served in low density areas. 68 high density areas have been designated, comprising cities, major towns and a few transport hubs. The more attractive spectrum in the award is the 26 GHz band, which has been split into two parts reflecting current usage. Ofcom is partitioning each band into 200 MHz blocks for auction, with licences having 15 years duration and no roll out obligations. Each licence will apply across all 68 high density locations. The auction process follows a familiar route, with qualification followed by bidding for generic lots in a price ascending clock stage. Once there is no excess demand across all lots, bidding in the clock phase ends. This will be followed by an assignment stage, where winning bidders participate in a sealed-bid second-price auction for specific frequency locations for contiguous lots won. Ofcom will determine the winning combination of bids as that which maximizes value. Reserve prices are modest, set at £2m for each 26 GHz lot and  £1m for each 40 GHz lot, exactly what we advised in our March 2023 review of mmWave auctions, https://lnkd.in/eVt6x4yG If you would like to know more about the forthcoming UK mmWave auction, please contact me.

Open Radio Access Network: Is a concept that revolves around the interoperability and standardization of RAN components, encompassing a uniform connectivity standard for white-box hardware as well as open-source software elements provided by various suppliers. The Open RAN design combines a customizable base station software stack with readily available hardware, enabling baseband and radio unit elements from various vendors to work harmoniously. The Open RAN architecture defined by the O-RAN Alliance and supported by 3GPP can be virtualized and containerized by breaking down traditional remote radio head RRH and baseband units BBUs into open radio units O-RUs, open distributed units O-DUs, and open centralized units O-CUs, all while using open and interoperable components. Open RAN sets efficient 5G RAN goals by focusing on efficiency, intelligence, and versatility. Implementing Open RAN at the edge of the network facilitates 5G functionalities like self-driving vehicles, which depend on fast response times and strong dependability, all the while efficiently catering to various network slicing scenarios. Open RAN also allows for safe and effective wireless firmware updates. What is the difference between RAN and O-RAN? please answer this question in the comments.

On the #security front, issue #8 of 3GPP newsletter contains an article on the Security Assurance (#SCAS) specifications developed by SA WG3. Thanks to my colleagues in SA3, we have been prolific in creating Security Assurance specifications for all major EPC nodes, eNB (4G) and almost all 5G core network nodes. Theses specifications define the basic fundamental test cases which are are used in the GSMA NESAS certification program which are mandatory for the EU and many other regional #cyber-certification and compliance programs.

This paper presents a novel and accurate procedure for designing a #Doherty #power #amplifier (#DPA) for wireless systems. The method is based on a systematic approach to designing the matching networks of both Main and Auxiliary devices, which employs an optimization process to set their input impedance in the corresponding optimal regions obtained from the standard load- and source-pull simulations. To import the optimum regions of each device into the optimization algorithm, mathematical expressions are derived and graphically reported on the Smith chart. Besides this, the authors have developed an accurate method to account for the loading effect of the Auxiliary amplifier on the Main one at back-off when designing the Main PA. ---- Mohammad Shahmoradi, Sayyed Hossein Javid Hosseini, Vahid Nayyeri, Rocco Giofrè, Paolo Colantonio More details can be found at this link: https://lnkd.in/ea9mj_aq
