Indicator Description - Huawei EchoLife HG8120 series Quick Start Manual

1. Decrease the number of walls and ceilings between HG8247H and other network
devices.
Each wall or ceiling reduces the coverage of a wireless network by one to 30 meters.
Install HG8247H at a proper place to avoid walls or ceilings whenever possible.
2. Observe the straight line rule when installing network devices.
The distance for which signals have to traverse at a 45° corner of two 0.5 meter-thick
walls reaches approximately one meter. To better receive signals, devices should be
installed at places where signals can directly traverse walls or ceilings.
3. Note the impact of building materials on the wireless network coverage.
A metal door or aluminum wall may limit the coverage of a wireless network. Install
access points, wireless routers, and computers, so signals can traverse walls or open
passageways. Materials and objects such as FRP products, metal products, insulative
walls, filing cabinets, bricks, and concrete weaken radio signals.
4. When connecting ONT (such as HG8247H) to a wireless network, keep it far from
the following devices:

Electronic devices or components that produce RF noises (keep a distance of more than 2
meters between such a device and HG8247H.)

2.4 GHz wireless mobile phones or X-10 devices (such as microwave ovens, home
security systems, blue-tooth devices, and refrigerators) that greatly weaken or even
eliminate radio signals. Even if a 2.4 GHz wireless mobile phone is not connected to a
wireless network, the phone base still sends signals that interfere the wireless network.
5. In order to avoid the possibility of exceeding the Europe radio frequency
exposure limits, human proximity to the equipment shall not be less than 20 cm.
