The first is the regional BWA, which was introduced in 2008 for the purpose of eliminating the digital divide.The license system is for each municipality, and as of March 1, 2018, it is used by 63 companies and organizations such as CATV operators and local governments.In addition to WiMAX, which has been used from the beginning, the use of LTE (AXGP, WiMAX R2.1 AE) as an advanced system was approved in 2014, creating the possibility of using it for "private LTE". ..Since the operating frequency band (2575 to 2595MHz) of the regional BWA is included in the 2.5GHz band of the LTE international band (used by UQ Communications and Wireless City Planning in Japan), commercially available smartphones and data terminals can be used. Network equipment also has the advantage of being easy to procure.sXGP is a technology standardized by the XGP Forum, which has standardized PHS and AXGP, as a successor to the self-employed PHS used for business cordless.Note that the 1.9GHz band self-employed wireless band (1893.5 to 1906.1MHz) used for digital cordless phones in Japan is included in the 1.9GHz band (band 39) used for China Mobile's commercial LTE service.By standardizing the specifications, it was developed with the aim of using a band 39 compatible terminal, which is already widely distributed in the market, as a slave unit.In fact, with sXGP, although the terminal manufacturer needs to obtain TELEC certification again, it can be used without any modification to commercially available smartphones.Although sXGP has been standardized as a new digital cordless phone, expectations are rising as an unlicensed band IoT wireless system that can be used without obtaining a license."Of course, the use of sXGP is to replace cordless telephones in business offices, but it is one of them. Unlicensed that can handle not only voice but also large-capacity data transmission such as surveillance cameras and digital signage with one network. The essence of sXGP is that it is a band's IoT wireless system, "says Noriaki Hibi, BD Director of Bisel's Japan Japan BD Director, who launched the first sXGP access point product in January this year.
