Problems of existing sXGP femtocell and new C-RAN solutions from Baicells

sXGP is unlicense radio, but it is not being used effectively. Existing sXGP eNB are femtocells which are not suitable for area formation. We'd like to share our views.
technical challenges
・sXGP is TDD-LTE requires synchronization.
GPS signal does not reach inside the building, pull in the cable is hard.
・Cells interfere with each other, requires area design.
Need specialized skills and expensive tools.
business challenges
・It's hard to offer an advantage over WiFi.
・sXGP requires an EPC core. Initial and maintenance costs are high.

To solve them, we developed C-RAN sXGP eNB.
C-RAN is widely adopted by carriers, by accommodating multiple radio units (RU) in a single control unit (BU), multiple radio units (RU) can cover an area as a single large cell. GPS signals is connected to BU, not required to be pulled to all RUs. In addition, since RUs work as the same cell, RUs can be placed freely.
High-performance NXP chipset is used, one BBU can support max 256 active users, We can alos provide 10MHz bandwidth by updating SW only in the future.

To compete with WiFi, we focused on voice quality.
sXGP has VoLTE. By QoS control, reliable and high-quality calls are provided.
But if WiFi VoIP is congested, voice quality deteriorates, problems such as not receiving calls or repeated calls are likely to occur.
As for cost reduction, we convert the EPC core to SW and put it in the BBU.
If the EPC core device is no longer required, costs will be reduced a lot.
There are situations where Wi-Fi is not good at, voice calls, etc. You may create unique and high-quality services by sXGP. Please consider.

Introduction of 802.11ah that started commercial deployment to drive high-value IoT

The digital transformation toward Society 5.0 pushes the demand for high-value IoT deployment in/across all industries. It requires higher speeds than previous LPWA and a wider area than previous Wi-Fi. The essential enabler is IEEE 802.11ah, Wi-Fi for IoT that anyone can freely deploy. The capabilities, expected usage scenarios, and the next step for 802.11ah, which began commercial deployment last September, are introduced.

Future wireless space evolved by enterprise wireless LAN mesh and its applications

Cellular and Wi-Fi, the two main types of mobile communication, both use a server-client form of communication in which terminals connect to a base station and communicate with each other. In contrast, there is a form of communication in which terminals connect directly to each other. This is known as peer-to-peer communication. The form of communication known as wireless mesh is a type of peer-to-peer communication in which terminals relay messages to each other in a bucket relay fashion so that terminals in remote locations can communicate with each other without having to go through a base station.
 PicoCELA is a company with its own wireless mesh technology and develops and sells Wi-Fi access points that use this technology for backhaul. Backhaul refers to the relay links that connect base stations to the Internet. The coverage area of each base station is getting smaller every year, requiring LAN cabling for more base stations, i.e. more backhaul. In anticipation of the proliferation of such small cells, the focus has turned to wireless mesh to reduce the need for cumbersome wired LAN cabling for backhaul, and Wi-Fi access points equipped with PicoCELA wireless mesh technology are being deployed at more than 1000 sites, mainly in Japan.
Developed as a backhaul for small cells, PicoCELA's wireless mesh technology solves the challenges specific to small cell deployments and provides extremely stable wireless mesh communications that can successfully withstand use in harsh enterprise environments. This high stability of wireless mesh technology can be applied in many other areas. This presentation describes PicoCELA's wireless mesh technology, followed by some use cases and finally future application developments.

Compact and Low-Power Open-Innovation Platform Leafony Accelerates Developments of IoT/CPS Applications

Leafony is an ultra-low power platform for IoT/CPS system development, consisting of ultra-small functional modules that can be easily assembled like a block toy. It covers wireless communication functions such as BLE, Wi-Fi, and LTE-M, and has been in use by companies and educational institutions. Anyone can quickly try out applications and service ideas because software development can be done easily using the Arduino development environment or PlatformIO. Hardware specifications, circuit diagrams, and software information are all open. Each functional module is called 'leaf' since it is small and green. The features of Leafony are as follows:

1) Ultra-small and easy to assemble
2) Low power consumption, capable of battery or solar power operation
3) Open-source hardware/software
4) Easy to create original leaves

In addition, an ultra-low power Arm-based 32-bit microcontroller leaf capable of executing Edge AI is also available, expanding its scope of application. In this presentation, Leafony's technology and the latest information will be introduced.

The Challenges and Solutions of millimeter-wave Deployment

5G millimeter-wave features high throughput and low latency. However, the millimeter-wave propagation characteristics fade significantly in various environments. Since millimeter-wave signal penetration is insufficient to reach dead-ends, it is also often necessary to purposefully construct a specific secure area, such as in factories, hospitals, or private networks. To increase coverage and customize the signal distribution, TMYTEK has created a cost-effective total solution.

Beamforming can compensate for the propagation loss by aggregating the antenna array gain toward a direction. To extend 5G millimeter-wave signal coverage, TMYTEK XRifle Reflector utilizes surface (ES) technology, passive reflector patterns printed on interior glass or printed circuit board (PCB). The TMYTEK Reflector has eight commonly used reflection angles. It enhances the signal quality for fields with poor or absent 5G NR millimeter-wave signal by reflecting signals from various angles. You can quickly create signal hot-zones and cold-zones by simulating an actual millimeter-wave deployment, which will empower telecom and system integrators to create the smart deployments.


Features
● 8 different commonly used reflection angles available
● Passive reflector so no power is required
● Bi-directional

"freeRAN", a small wireless base station that can easily build a private network environment without a license

"freeRAN" is a wireless device that builds a private LTE environment compatible with 1.9GHz band sXGP, which has appeared as a successor to PHS, whose service is about to end. sXGP can be used as a terminal for smartphones, and voice and data communication is also possible, so it can be used not only as an alternative to on-premises PHS used as an extension in hospitals, but also as a data communication application for IoT in factories, etc. is. It is small, has a high degree of freedom in installation location, and easily realizes a highly secure closed network environment.
Rikei will introduce the features of "freeRAN" from the manufacturer, Ubiik Inc.
