25 December 2001 - JATE - Announced Changes - Summary

This should be our last News update of the year 2001: JATE has renewed their home page, with updated information related to the new certification scheme to apply in January 2002.

An English version is available at the following link: http://www.jate.or.jp with the new fees, application examples, information for first time applicants, and more !


5 December 2001 - JATE - Announced Changes - Summary

JATE has detailed the changes to occur to the current certification system during a presentation meeting held today In Tokyo.
The scope of changes was submitted to the Ministry of of Public Management, Home Affairs, Posts and Telecommunications on the 30 November and has not been officially accepted yet.


Major changes announced are:


1 - Reduction of the JATE certification fees

Precise figures were not given yet, but in general, a reduction of the fees between 10% and 30% is expected. (The new fees will be confirmed as soon as the Ministry approves the new scheme.)


2 - Reduction of the timeframe to obtain the certification

Until now, the limit to issue the certificate was set to 30 days. It was reduced to 20 days after the submission date. (As a remark, this should not affect our customers, used to obtain the approval within a few days after the submission date...)


3 - Extension of the validity period for the quality control process documents

The current 1 year validity period will be extended to a maximum of 3 years, provided the submitted Quality Control Description documents (and ISO 900x related certificates) remain valid during this period.


4 - Re-classification of ISDN S/T interfaces in the Technical Conditions

Until now, an ISDN equipment with an S/T interface was submitted for compliance to Technical Conditions (L2, L3) and Technical Requirements (S/T interface). The Re-classification of the S/T interface in the Technical Conditions will mostly result in a reduction of the JATE fee. Only the highest fee for the Technical Conditions will apply. Therefore, and with the current JATE fees, JPY 434,800 for an ISDN S/T equipment fee will be reduced to JPY 330,000, and in addition, the above mentioned 10 to 30% reduction will apply.


These changes will apply on the 4 January 2002, and updated information should be posted on JATE's home page soon. 


Other changes, specific  to PBXes, or to very particular situations, were also announced. Please contact us for more information !


November 2001 - JATE - Changes to come

With the recent modification of the Telecommunications Business Law and the Radio Law, JATE is reviewing its current requirements. The scope of the changes to come will be presented during a meeting to be held on the 5th December.

The following items are expected to change:

- JATE fees: to be reviewed. JATE fees for simple or single interface equipment are expected to decrease. On another hand, fees for larger equipment such as PBX + Mobile phone Systems Combo should increase, reflecting the effort required  during the inspection of the application file.

- Services and Interfaces Categories: Some Technical Requirements standards are expected to become Technical Conditions. The requirements themselves should not change, but as a result, fee for multiple interfaces equipment should decrease.

- Relaxation, extension of validity period for some documents.


...And other changes ! Please check this site again. Updated information will be available here, after the 5th December !

November 2001 - Wireless LAN - current developments

As available on the URL of the Ministry of Public Management, Home Affairs, Posts and Telecommunications (formerly Ministry of Posts and Telecommunications), the following topics and projects related to Wireless LANs  are currently being discussed:

2.4GHz Band

- Increase of the maximum transmission speed from 10Mb/s to 20Mb/s in using OFDM technology

- increase of the max. gain of the antenna from 2.14dBi to 12.14dBi with conditions on the radiation angle range

- Applicability of FH technology to RFID equipment

5.3GHz Band

- The extension of the 5.2GHz band for Wireless LAN to 5.3GHz will probably not happen soon, due to the fat that the 5.3GHz band is used by  meteorology radars 

 5.0GHz Band

- The extension of the 5.2GHz band for Wireless LAN to the 4,900 - 5,000MHz band is currently under study. 


More information (also related to 25GHz LAN) to come soon !

November 2001 - We have Moved !

September 2001 - Interruption of postal and courier services to and from the USA

As a consequence of Tuesday's tragic attacks, postal and courier service between between Japan and the USA is interrupted indefinitely. Until the traffic is back to normal with concerned countries,  JATE will accept the submission of application files with copies or faxes of the original signed cover pages. JATE will issue the reserved approval number, but there is no guarantee they can issue the final certificate, until they receive the original signed documents.  


Our thoughts and prayers are with the victims of Tuesday's terrorist attacks.

August 2001 - 5.2GHz Band Wireless LAN systems in Japan

Current situation in Japan, regulatory compliance, involved organizations, relations with international standards, restrictions in Japan, testing and approval methods.


Available 5.2GHz band standards for Japan

First Edition, 14 December 2000

Available languages: Japanese only – The release of an English version is not scheduled


-          HiSWANa stands for High Speed Wireless Access Network Type a

-          RLC  (Radio Link Control) sub-layer standard is referred to the ETSI BRAN HIPERPLAN/2 RLC standard [4] However, the following items are not applicable: direct link/direct mode, DFS (Dynamic Frequency Selection), TCP (Transfer Power Control)


ARIB STD-T71 – Low power data communication systems broadband mobile access communication system (CSMA)

First Edition, 14 December 2000
