Co-investment, like mobile network sharing is a cost efficiency enabler that may accelerate price decrease, may allow earlier, higher coverage and may improve capacity and quality parameters, like download speed, therefore altogether contributes to social welfare increase. The purpose of this paper to assess the Hungarian mobile network sharing that not cleared by the competition regulator, however has been placed in unchanged form for 8 years. The research question is to assess what is the connection between mobile network sharing and social welfare improvement at 4G - 5G mobile broadband rollout. The finding is that, majority of network sharing procompetitive effects allowing benefits, but anticompetitive effects not causing marked distortion. Affordable connectivity prices for information society roots in operators’ cost efficiency, however further research required to assess proper level of efficiency gains pass through to customers and appropriate level of access pricing to shared infrastructure for other rival operators in Hungary. Mobile Network Sharing’s benefits may outweigh potential drawbacks, but due to lack of regulatory clearance, 5G rollout launched without sharing, causing social welfare loss. The originality of the empirical research is despite network sharing not cleared, procompetitive advantages may outweigh anticompetitive ones.","PeriodicalId":42504,"journal":{"name":"Infocommunications Journal","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82172301","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, one of the promising scheme is Non-Orthogonal Multiple Access (NOMA), where, unlike the traditional Orthogonal Multiple Access, OMA solution, signals for the different users overlap in some domain (power-domain NOMA, code-domain NOMA, etc). In order to evaluate the performance of any NOMA scheme, we need to compare the achievable bit rates of the users (the capacity region) to an OMA case with comparable parameters (for example, same total bandwidth, same total power and same channel conditions, etc). To make this comparison, we first need to know the capacity region for the OMA cases. Many papers make such comparison without detailing the derivation of the capacity region of the OMA case they compare to [1], [2], [3], [4]. In some cases, we have only one free parameter to choose (for example in uplink frequency division multiplexing systems for two users, it is the bandwidth ratio between the users), and the achievable capacity can be directly calculated for both users depending on the single parameter (hence the boundary of the capacity region is trivial). In other cases, such as downlink frequency division multiplexing systems, even for only two users, we have to allocate optimally two resources between the users: the bandwidth and the base station’s available power. Hence, it is far from being trivial to determine which combination is better and where the boundary of the capacity region is. In this paper, we provide a derivation for that case.","PeriodicalId":42504,"journal":{"name":"Infocommunications Journal","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74524478","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
