The publisher has been following the small cells' development from the beginning of their commercialization and contributed several technical/marketing reports on this subject.

This report updates previous studies as well as adds new information. The report presents in detailed and easily understandable terms an independent, unbiased analysis, which reflects progress in small cells and their backhaul solutions developments. Through vendors’ interviews and the analysis of multiple data sources, the report provides the latest, accurate marketing and technical information. 

In particular, the report analyzes dynamically evolving small-cell technologies, concentrating on their advantages, varieties, and specifics. Major applications are presented, and standardization developments are emphasized. Based on the in-depth industry analysis of multiple studies and interviews with vendors, market prognoses (2023-2027) are presented. The survey of more than thirty-five small cell equipment vendors and their portfolios is also provided. It is shown that 4G mobile technologies (concurrent with 5G) will concentrate on building HetNets in which small cells play an important role.

The report emphasizes that the small cell backhaul solution may prove or break the small cell business case. Specifics of small cell backhauls, their varieties, and differences from macro cell backhauls are analyzed in detail. The need for standardization is emphasized. The study of industry trends, interviews with vendors, and the analysis of publicly available statistical data helped to perform the marketing analysis. The survey of vendors (about 30 manufacturers of small cell backhaul solutions) reflects this industry's specifics and trends. There is a range of use cases for open access small cells, from targeted demand hotspots in city centers, through generalized capacity uplift, to serving not-spots in remote rural areas. In each case, the emphasis on backhaul requirements shifts, and aspects that are critical to one type of deployment can be relaxed in others. Solutions with different characteristics will address the needs of different types of small cell backhaul in different areas.

Fiber and microwave are complementary technologies with different use cases. Microwave backhaul allows for a faster and more cost-efficient rollout compared with fiber while fiber offers greater capacities. In a positive development, more countries have been making the E-band available for microwave backhaul.

Microwave is the preferred solution for long-distance transfers. It is also the better choice in countries where regulatory problems complicate fiber rollouts, such as India or Egypt.

Attachments contain the in-depth analysis of prevailing small cell microwave and Wi-Fi backhaul solutions:

1. 60 GHz technologies (V-band). Both Ethernet radio and 802.11ad/802.11ay solutions are addressed. Marketing and technical specifics are described in detail. The survey of vendors is also provided. 
2. 802.11ac (Wi-Fi 5). The technology supports throughput, range, and other characteristics that satisfy small cell backhaul requirements. Authors analyzed the specifics of Wi-Fi 5 as they relate to the small cell backhaul application; they also analyzed the market and vendors’ portfolios. 
3. 802.11ax (Wi-Fi 6) - is also detailed.
4. 802.11be (Wi-Fi 7) - is introduced.
5. E-band radio. The popularity of this radio for discussed applications is growing, and this trend will be even more pronounced in the 5G era.

Wireless backhauls for SCs are prevailing now and it is expected that they will keep this leadership position in the future. 

This report provides SCs and their backhaul solutions technological and marketing analysis. It can be useful for service providers, vendors, network operators and managers, Enterprise IT staff, investors, and end users seeking to gain a deeper understanding of the SC developmental trends in the mobile industry.

The end users will gain a more thorough understanding of technologies and their capabilities as well as economics.

The report also surveys patents related to Wi-Fi 6 and 802.11ay standards.

Methodology

Considerable research was done using the Internet. Information from various Web sites was studied and analyzed; evaluation of publicly available marketing and technical publications was conducted.

Telephone conversations and interviews were held with industry analysts, technical experts and executives. In addition to these interviews and primary research, secondary sources were used to develop a more complete mosaic of the market landscape, including industry and trade publications, conferences and seminars.

The overriding objective throughout the work has been to provide valid and relevant information. This has led to a continual review and update of the information content.
