Softbank Japan's Ultra Wifi 4G (a.k.a AXGP)


In Japan, they love to re-brand the standard technologies into something more interesting to attract people's attention. In a way they are right as they want to offer a service rather than a technology. Couple of years back NTT Docomo launched its Crossy service, that was offering LTE with upto 75Mbps dl speeds. Yesterday, I read about Softbank launching their 4G service that is based on AXGP format.

I did blog about XGP many years back but AGXP, which stands for Advanced XGP may not be very well related to XGP. According to ZTE Technologies magazine:

In November 2011, Japan’s third largest mobile operator, Softbank, made AXGP commercially available. AXGP is similar to TD-LTE, and has been deployed in Japan in conjunction with ZTE and Huawei. Two thousand base stations were built in the fi rst phase, and there will be up to 10,000 base stations built in the second phase. Ninety-nine percent of the Japanese population will be covered by 2012. So far, the Softbank network is the largest commercial TD-LTE network in the world. Wang Jianzhou, chairman of China Mobile, said, “If in the past the TD-LTE network was just a stratagem on paper, now it has turned into a reality.”

The following are some more details edited from a Japanese website (translation via Chrome):


High-speed data communication service Wireless City Planning of the SOFTBANK Group (Wireless City Planning, WCP) will be scheduled after February 2012, adopted a new communication method AXGP is, in excess of up to 100Mbps downlink high-speed communication is a feature . It was an opportunity to use the test machine prior to the start of service for general users, to report a sense of its use. 


 "AXGP" was developed inherit the "PHS" next generation of Willcom

 "AXGP" high-speed data transmission technology WCP employs a technology that was originally planned to use the 2.5GHz band has been assigned from the Ministry of Internal Affairs and Communications Willcom to deploy as "PHS" next generation. Had to expand the limited service area and some intended for users under the name of "WILLCOM CORE XGP" PHS is then the next generation, business is XGP is "Wireless City Planning" of Softbank subsidiary company under the reorganization proceedings of Willcom inheritance. Provide the service as "AXGP" form of communication is an evolved version of XGP in WCP.


 AXGP, in addition to the XGP also hand while inheriting the "micro cell" was characteristic of PHS, PHS has been developed as the next generation, that have become compatible with the method of TD-LTE. Including China and India, that are compatible with the TD-LTE system is expected to expand in many parts of the world, the benefits can be expected that international expansion is expected. 

 Service is initially started up to 76Mbps. The first bullet is the mobile router products

 AXGP is at present, but services have been provided for users in a small part had been using the service test XGP Willcom old, since the February 2012 service "SoftBank 4G for general users as MVNO Softbank Mobile plans to start ". The communication speed up to 110Mbps downstream and 15Mbps and maximum upstream and downstream speeds in excess of 100Mbps for speed has become a feature.


 At the start of service, the mobile router will "101SI" made of (SII) will be released at the same time Seiko Instruments. However, 101SI has become a maximum 76Mbps to 110Mbps falling down is the theoretical value of the service, at the start of the service is not provided in the full spec. Terminal is planned to also provide support AXGP Then, in the year 2012 is also powered smartphone will be compatible with AXGP. In addition, "101SI" to support (42Mbps maximum downlink, 5.7Mbps uplink maximum) "ULTRASPEED" Softbank mobile. 




Ultra-high speed in the area. Hope to plan area at the time of service and rates

 Although a measurement with the outdoor area was limited, with respect to communication speed was very good results with the results fit. Most favorable conditions and even the user does not exist before the start of the service say that already provide services as high-speed data communication, "Xi" of NTT DoCoMo, Inc., or UQ Communications 37.5Mbps, which is the maximum theoretical value of outdoor (Kurosshi~i) It was also a number greater than the maximum 40Mbps "UQ WiMAX" of is very encouraging.


 However, the decisive factor in mobile data communications is not only communication speed, three elements of the communication charge is important and easy-to-use, deployment area, including "ease of connection." In the area at the moment of some are very fast and are limited in the Yamanote Line, but is a matter of course in order before the service, ease of connection of the fact there are many parts of the still unknown. Also, I'd be anxious and services are provided in the fee structure what.


 SoftBank is to introduce a flat-rate voice among their users ahead of any other mobile phone operators so far, campaigns expand the iPhone however any inexpensive flat-rate packet. Further has a track record of just made me started to increase subscribers by the "straight-line with anyone" WILLCOM has also continued to decline in subscribers. Softbank Mobile also be deployed as a MVNO, at the time of release of the service that you want to use the AXGP expect a bold expansion of unique services and Softbank WCP, which is the same group Softbank.


Softbank's website is billing this as 'Ultra Wifi 4G' and will be launched to public this Friday, just in time for MWC12.

Loving it. Just picked up my router the other day and the first thing I noticed was huge difference in speed compared to my UQ Wimax.

AGXP is really just a name for PRE-LTE to be honest. Whilst softbanks 4G LTE network is being built they are trying to make some dollars by offering it to some customers they have called this AXGP which is exactly the same as LTE but the 4G infra wont b completed until autumn 2012 and then AXGP wil disapear and we will only have LTE

what is the difference between 3g and 4g?

Kelvin said...

So far technology developer and specially heavily using 3G and 4G networks mobile brands are not promoting difference between 3G and 4G network properly. I think there is no difference of performance in these service or else we are not understanding the difference. Thus I guess firstly we needed to learn what benefits we will have using 4G networks, instead we are having same performance in 3G networks.
