Nowadays, portable game consoles are also built -in wireless LAN functions.Laptops have spread to no products that do not have a wireless LAN function, from space -saving machines used in companies and homes to mobile notebooks.
However, one step out of the base, the situation is very delayed.Wireless LAN hot spots for commercial use are served mainly at stations, airports, and fast food stores, but unfortunately the available areas are very limited.Nowadays, next -generation public broadband services such as WiMAX are appearing, but it is still accessible in limited places around the large cities.In order to use, WiMAX communication functions and communication adapters must be prepared for each device (although there are wireless LAN router products).
Is there no broadband service that can be connected in a large area using a wireless LAN that many devices standard?What responded to the voice was the ultra -small wireless LAN router "Pocket WiFi" that uses 3G mobile phone infrastructure.This time, I tried a new product "C01HW" provided by SoftBank Mobile.
"Pocket Wifi SoftBank C01HW".The area is almost a business card.The thickness is about 14mm and the weight is 80g, and you can easily put it in your pocket.The surface is silver and black, and the back is white coloring
To be honest, when I got C01HW, I had no idea what kind of equipment it worked.It is a compact device that looks like a portable audio player, and is a business card size that fits in the palm of your hand, as well as a product, and weighs only 80g.
The operation switch is on the right side.From left, power button, LAN connection on/off, WAN connection on/off.Both operate by holding a long press for 2 seconds.A micro SD card slot (up to 16GB) is available on the left side, and it can be used as a USB memory when connecting to a personal computer.
The lower part is equipped with a miniusb connector for connection with a personal computer.Charging to the built -in battery is also performed from the USB connector (AC adapter is also included)
C01HW is a wireless LAN router that also serves as a wireless LAN access point and a router.Generally speaking, the wireless LAN router is connected to a broadband line such as an optical fiber or ADSL line, and the LAN side is connected by wireless data communication that complies with standards such as 802.11b/g/n.The C01HW also has the same configuration on the wireless LAN side, but a 3G mobile phone network is used on the WAN side.
This product was originally based on a product called "I-Mo" manufactured by Huawei Technologies (Hua Technology), which is known as e-mobile's data terminal manufacturer.E -Mobile has been selling similar devices for some time.In the SoftBank Mobile version of the C01HW, in addition to the 3G line of SoftBank (up to 7.2Mbps/up to 1.4Mbps) in a wide range of available areas, e -mobile's HSPA line (up to 7.2Mbps/up to 5.8Mbps).The advantage is that both can be used properly.
When you open the back cover, you can see a dedicated battery (lithium -ion rechargeable battery).The SIM card -mounted slot required for the WAN side connection is under the battery
The wireless connection between the WAN / LAN side has been connected, so there is no annoying cable connection, and no connection devices are selected.If the wireless LAN function is built in, it can be used freely, whether it is a mobile game or a smartphone, or even a full -fledged mobile notebook.However, due to the substantial bandwidth, there are up to five wireless LAN devices that can connect to one C01HW at the same time.
