Demonstration of IFoF based 5G Mobile Fronthaul in 28 GHz Millimeter Wave Testbed Supporting Giga-bit Mobile Services

Analog IFoF/mmWave 5G Optical Fronthaul Architecture for Hot-Spots Using Multi-channel OFDM-Based WDM Signals

“…One of the directions is to employ the technology that can seamlessly combine the wireless access networks with the optical transport. Since optical fiber has chosen as the means to transport data to the centralized Base-Band Units (BBUs), analog Intermediate Frequency over Fiber (IFoF) technology [10] is currently investigated as an efficient fronthaul technique for distributing data from the BBU to a large number of Remote Radio Heads (RRHs) in a bandwidth-and cost-efficient manner. The advantage of IFoF is that it utilizes aggregation of mobile signals in intermediate frequencies and modulation with cost-efficient and low bandwidth devices [11], without adding any extra delay due to digital procedures as in the equivalent Common Public Radio Interface (CPRI)-based schemes [12].…”

Up to now, most of the analog IFoFbased demonstrations have been mainly evaluated for single carrier data signals with bandwidth up to 1Gb/s [11], or for OFDM signals with channel bandwidth less than 200 MHz [10,[13][14].…”

The Impact of Service Quality, Subjective Norms, and Voluntariness on Acceptance of Provider’s Mobile Telecommunication Service in Jordan

“…In so doing, the private sector was welcomed to participate and invest in the sector's development [2]. Despite the expanding studies in literature, empirical evidence remained minimal on the valuable service elements [3][4][5]. As a result, the underlying reasons behind the consumers' adoption and intention towards adopting services remained ambiguous [6].…”
