On September 14, 2021, Softbank announced the release of the 5G compatible home router “Air Terminal 5” and the handling of Google’s 5G smartphone “Google Pixel 6/6 Pro”. He also explained the current issues and future developments of the 5G area, and announced that he plans to achieve a population coverage rate of 80% by the end of October 2021.
“Air Terminal 5” is a 5G compatible home router. In the 5G area, in addition to achieving a maximum downlink communication speed of 2.1 Gbps, more stable communication is provided by installing an “antenna selection” that automatically selects 4 antennas with good reception sensitivity from the 8 built-in antennas. Can be done. It will be available from October, and reservations will be accepted from September 15. The main body is 71,280 yen, but it will be virtually free after 36 months of continuous use.
Although it is a noteworthy 5G communication function, the supported band is only n77 (Sub6), and it is not compatible with millimeter waves and frequency bands diverted from 4G. On the other hand, regarding 4G communication, it is compatible with B41 (AXGP) and LTE B1 and B42, and is basically the same as the previous model “Air Terminal 4”. In addition, Wi-Fi is compatible with Wi-Fi 6 (ax) in addition to the conventional IEEE802.11a / b / g / n / ac. The maximum number of Wi-Fi devices that can be connected has doubled from 64 in “Air Terminal 4” to 128.
In addition, a new rate plan “Air 4G / 5G common plan” suitable for this machine will start service from September 15. The monthly usage fee for the new plan is 5,368 yen, which is the same as before, which was compatible with 4G, and the contract period and contract cancellation fee have been abolished. There is no limit to the communication capacity, but as in the past, the communication speed may be limited during times of heavy use such as at night. In addition, the telephone service “Ouchi no Denwa”, which can be used by taking over the telephone number of a landline phone, can be used free of charge by using various campaigns scheduled to be implemented from December 2021.
In addition, with the launch of this product, a discount campaign “SoftBank Air Start Discount Plus” for new subscribers will be launched. In this campaign, a monthly discount of 1,188 yen will be applied for 24 months. In addition, when changing the model from “Air Terminal 4” terminal to “Air Terminal 5”, there will be a privilege to make the remaining bonds virtually free.
As for smartphone terminals, it was also revealed that two models, the latest smartphone “Google Pixel 6” scheduled to be released by Google and its higher model “Google Pixel 6 Pro”, will be released this fall. The “Google Pixel 6 Pro” will be sold exclusively by domestic telecommunications carriers.
At the recital, the latest area development status of the 5G network provided by SoftBank was also explained. SOFTBANK is promoting rapid expansion of the 5G communication area by using the frequency band converted from 4G and the infrastructure sharing company “JAPAN 5G” with KDDI, etc., and by the end of October 2021, nationwide. It was announced that the population coverage rate will reach 80%. Furthermore, it was announced again that the population coverage rate is expected to reach 90% by the end of 2021.
In 5G, a “packet stop” may occur in which data communication cannot be performed in a place away from the base station where the radio wave is weak. This occurs in 5G areas where radio waves are so weak that communication is not possible, and the baton touch to 4G does not work, which is a problem in the 5G popularization period. On the other hand, Softbank says that by adopting a mechanism that links 5G and 4G well, it suppresses the stopping of packages and realizes a smooth network.
In 1999, a mobile phone compatible Internet connection service started. The mobile camera started when online services such as bank transfer, live ticket purchase, and town page search became available on the mobile phone, in addition to Internet mail. By the way, it was this year that the phone numbers of PHS and mobile phones changed from 10 digits to 11 digits.
In such a turbulent era, au’s first mobile camera was the “PashaPa” that appeared in 2000. However, this was not an integrated type, but a camera unit connected to the terminal of the mobile phone.
PashaPa is a small camera with 100,000 pixels, and you can select 2 patterns for the captured image size. The normal format is 120 x 120 pixels, and the CIF format, which is larger than the normal format, is 352 x 288 pixels. With CIF, it was not possible to view photos on a mobile phone, and the specifications were such that they could be viewed after being sent to a computer or other device.
What is surprising is the small number of saved sheets. Approximately 30 for normal and approximately 3 for CIF. It was an era when there was still a big difference from smartphones that can shoot continuously.
In 2001, the Pacha Pa 2 with a flash function was released.
From here, verification starts on the actual machine. Since the first camera mobile phone was almost 20 years old, there is a possibility that it will not start just by charging it, so this time, I prepared a multi-power supply in the center of the photo as a secret weapon and challenged shooting. KDDI’s battery teacher, Kyoichi Shinbo, and his assistant, Yuki Irisawa, will cooperate in the restart.
According to Shinbo, old mobile phones often have different power supply specifications depending on the manufacturer, model, and era, and most of the batteries have deteriorated, so now that nearly 20 years have passed, even if they are charged normally,
