“…Since Femtos are deployed to offer high data rate services to indoor (paid) users in enterprise and residential buildings, each Femto is configured with a list of subscribers called Subscriber Group (SG) that can access them [24]. The users not belonging to this list belong to the Non-Subscriber Group (NSG), and they are served by MBSs even when they are close to a Femto.…”

To boost the cellular system's capacity, the operator's have started to reuse the same licensed spectrum by deploying 4G LTE small cells (i.e., Femto Cells) in the past. But in time, these small cell licensed spectrum is not sufficient to satisfy future applications like augmented reality (AR) and virtual reality (VR). Hence, cellular operators look for alternate unlicensed spectrum in Wi-Fi 5 GHz band, later 3GPP named as LTE Licensed Assisted Access (LAA). The recent and current roll-out of LAA deployments (in developed nations like the US) provides an opportunity to understand coexistence's profound ground truth. This paper discusses a high-level overview of my past, present, and future research works in the direction of small cell benefits. In the future, we shift the focus onto the latest unlicensed band: 6 GHz, where the latest Wi-Fi version, 802.11ax, will coexist with the latest cellular technology, 5G New Radio (NR) in unlicensed.

“…Femtos deployed in enterprise and residential buildings guarantee high bandwidth services to a specific list of paid indoor users/subscribers called the Subscribers Group (SG) [26]. Each Femto allows access to users only in the SG and the indoor users not in the list are known as Non-subscriber Group (NSG), which are served by the MBSSs, regardless to their proximity to a Femto.…”

With the exponential increase in mobile users, the mobile data demand has grown tremendously. To meet these demands, cellular operators are constantly innovating to enhance the capacity of cellular systems. Consequently, operators have been reusing the licensed spectrum "spatially," by deploying 4G/LTE small cells (e.g., Femto Cells) in the past. However, despite the use of small cells, licensed spectrum will be unable to meet the consistently rising data traffic because of data-intensive applications such as augmented reality/virtual reality (AR/VR) and on-the-go high-definition video streaming. Applications such AR/VR and online gaming not only place extreme data demands on the network, but are also latency-critical. To meet the QoS guarantees, cellular operators have begun leveraging the unlicensed spectrum by coexisting with Wi-Fi in the 5 GHz band. The standardizing body 3GPP, has prescribed cellular standards for fair unlicensed coexistence with Wi-Fi, namely LTE Licensed Assisted Access (LAA), New Radio in unlicensed (NR-U), and NR in Millimeter. The rapid roll-out of LAA deployments in developed nations like the US, offers an opportunity to study and analyze the performance of unlicensed coexistence networks through real-world ground truth. Thus, this paper presents a high-level overview of past, present, and future of the research in small cell and unlicensed coexistence communication technologies. It outlines the vision for future research work in the recently allocated unlicensed spectrum: The 6 GHz band, where the latest Wi-Fi standard, IEEE 802.11ax, will coexist with the latest cellular technology, 5G New Radio (NR) in unlicensed.
