What is the impact of the termination of public PHS services on on-site PHS?
Public PHS service will end in March 2023. Along with this, it is expected that companies and local governments using PHS on the premises will also be affected.
"What is the impact on the on-site PHS when the public PHS service ends?"
"Can I continue to use PHS on the premises?"
There may be some on-site PHS managers who have questions such as. In this column, we will introduce the answers to these questions and the alternative next-generation communication standard "sXGP (shared eXtended Global Platform)".

Voice quality and PHS device price may be affected

Voice quality and PHS device price may be affected
It is said that there are two effects on the on-site PHS due to the termination of the public PHS service.
1. Deterioration of voice quality
It may affect the voice quality, which was also a feature of PHS. This is because the PHS on the premises realizes clear voice calls by taking a synchronization signal with the radio waves of the public PHS.
2. Soaring prices of PHS terminals and base stations
With the termination of public PHS services, the number of PHS terminals and base stations (access points) manufactured is expected to shrink, and these prices may rise.
There is no expiration date for PHS on the premises, but there is a risk
The expiration date of the PHS on the premises depends on whether the PHS terminal or base station you are using conforms to the "old spurious standard" or the "new spurious standard".
What is a spurious standard?
The spurious standard is a standard that defines the permissible value of the intensity of spurious emission (unnecessary radio waves emitted outside the required frequency band) of wireless devices, and was revised in 2005. The standard before the revision is the "old spurious standard" and the standard after the revision is the "new spurious standard".
PHS terminals and base stations that meet the old spurious standards
Originally, the expiration date for PHS terminals and base stations of the old spurious standard was until November 30, 2022, but it was decided in August 2021 that it will be extended for the time being due to the influence of Corona. However, it will inevitably become unavailable in the near future due to temporary treatment.
PHS terminals and base stations that meet the new spurious standards
On the other hand, there is currently no deadline for the new spurious standards. Therefore, if you replace the old spurious standard PHS terminal or base station with one that conforms to the new spurious standard, you can use the on-site PHS without worrying about the deadline.
Carefully replace base stations
In order to replace a base station that conforms to the old spurious standard with a base station that conforms to the new spurious standard, it is necessary to redesign the area for the base station to be replaced, and then install the base station and perform wiring work. It may be necessary to adjust the schedule as the PHS on the premises may not be available during the construction. In addition, as mentioned above, the impact of the suspension of public PHS services is also possible, so carefully consider whether to upgrade to an on-site PHS environment that conforms to the new spurious standards, even with cost and effort.
Next-generation communication standard "sXGP" that solves the problems of PHS on the premises
We have introduced issues related to all users of on-site PHS, such as the termination of public PHS services and spurious standards, but there are also unique issues depending on the type of industry that uses on-site PHS.
In the medical industry, in addition to the PHS terminal on the premises, it is necessary to carry a smartphone for external communication, a terminal for nurse call, a terminal for 3-point authentication, etc. together.
In the manufacturing industry, in order to promote the conversion of factories such as IoT and AGV to DX, the points that only voice calls of PHS on the premises can be made and the point that a base station must be installed exclusively are the bottleneck.
In many cases, local governments build a PHS on the premises as part of the BCP, but since it is difficult to send images and images of the disaster area on the PHS on the premises, there is a risk that the disaster headquarters will have an impact when checking the situation. there is.
One of the methods to solve all these issues and risks is sXGP (shared eXtended Global Platform).
・ Similar to PHS on the premises, it can be built without a license.
・ Not only calls but also data communication is possible.
・ Since the terminal is a smartphone, it is possible to consolidate multiple PHS terminals + smartphones into one.
Among them, the sXGP service provided by SoftBank enables extension calls even outside the premises using SoftBank's communication network, which is a unique feature of a telecommunications carrier.
