"Hikari" is the only choice if internet speed is important Considering reviewing old contracts

If you are dissatisfied with your internet speed, consider revising your fiber optic contract.

In an environment with a slow internet connection, even if you buy a new Wi-Fi router or computer, the speed of the internet will hardly change. If you find that your internet connection is the cause of your slow internet connection, consider reviewing your connection type and plan. By switching between them, the speed of the Internet can be increased. [Visual commentary] Here are the points to review the "Hikari" line

■Different speeds depending on plan and wiring method

In the case of fiber-optic lines, which are currently used in many households, the speed varies considerably depending on the contracted plan and the wiring method to the dwelling unit. different. For example, the fiber-optic line of FLET'S Hikari, which has many subscribers, had a maximum communication speed of only 200 megabits per second (Mbps, where mega is 1 million) in the early plans. The current mainstream is a plan with a maximum communication speed of 1 gigabit per second (Gbps, giga is 1 billion), and just changing to that will greatly increase the speed. In the case of apartments and condominiums, the difference between the optical distribution system, in which optical fiber is directly passed through the rooms, and the VDSL system, in which the signal is distributed to each room, also greatly affects the speed. By switching from the VDSL system to the optical wiring system, the speed will be greatly improved. However, in order to introduce the optical wiring system, it is essential to install optical fibers in the common areas of the housing complex. In condominiums, it is often necessary to go through a process to obtain the consent of the majority of residents, making it a high hurdle for individuals to introduce.

■Installation may take time

Currently, fiber-optic lines and home routers can be selected as Internet connection lines for general households. The optical line is connected to the house by optical fiber, and the ONU (optical network unit) converts the optical signal into a wired LAN, enabling high-speed and stable communication. When switching lines, optical lines are the first choice. However, installation requires construction, and depending on the plan and usage location, it may take a long time to open. In addition, depending on the housing complex, it may not be possible to connect optical fiber to each home for various reasons, and there are cases where the VDSL system has no choice but to continue. On the other hand, the home router uses 5th generation (5G) and 4th generation (4G LTE) mobile phone communication, so no installation work is required at the time of installation. You can use the Internet just by installing a home router in your home. However, in addition to being easily affected by radio wave conditions, 5G also has the problem of a narrow coverage area. In addition to optical lines and home routers, there is also an Internet connection method called ADSL. It has been used for a long time, but it has been decided that the service will be discontinued in 2023. If you are still using ADSL, it is urgent to consider switching lines.) When introducing an optical line, check if your residence is within the plan area. High-speed line services with communication speeds exceeding 1 Gbps (over Gigabit) are still available in only a few areas nationwide. For example, currently the maximum communication speed of optical lines for home use is 20 Gbps for "NURO Hikari" operated by Sony Network Communications, but the range of use of this plan is limited to some areas of Toshima-ku and Minato-ku, Tokyo (2021 (as of mid-November) is quite narrow. In addition, there is also a giga-exceeding service that limits the scope of provision to detached houses and condominiums of a certain size or less.
