![]() ![]() For dual-band devices blocked by obstructions, such as walls, band steering allows the use of the better-performing 2.4 GHz bands (right of the ‘wall’). ![]() Figure 1: Band steering can force dual-band devices to use the 5 GHz band, freeing up the 2.4 GHz band for devices that cannot connect to 5 GHz (left of the ‘wall’). When the access point is further away, or obstacles attenuate the signal, the client automatically switches to the 2.4 GHz bands less affected by the obstacles (Figure 1). When there’s a strong signal, the client connects using the 5 GHz band to the access point. That prevents the 5 GHz-capable devices from being slowed by older 802.11b/g devices.īand steering implementations continuously analyze the performance of the connection. Band steering ensures that devices such as televisions or mobile phones can use the 5 GHz band to achieve peak performance. If it is dual-band, the router will push the device to use the 5 GHz band and block it from connecting to the 2.4 GHz band. As each device connects to the network, the router determines if it is a dual-band device that can connect to either the 2.4 GHz or the 5 GHz band. It’s not an official Wi-Fi standard, but it’s an increasingly common technique. Generally, the 5 GHz band is the less-congested part of the network. Or a second (or third) Wi-Fi router can connect to the coax cable and form additional wireless Wi-Fi networks, all connected back to the main router for connection with the internet.ĭual-band Wi-Fi devices use band steering to optimize bandwidth use. The receiving devices at the far end of the extender, such as televisions, can connect directly to the coax cable and receive data. Wi-Fi network extenders can be used in two ways. MoCA 2.5 is capable of up to 2.5 Gbps actual throughputs and is backward interoperable with MoCA 2.0 and MoCA 1.1. The connection is often made using Multimedia over Coax (MoCA) 2.5 technology to extend the router’s signal throughout the building’s existing coax cabling, to bring an 802.11ax Wi-Fi signal to areas that can’t be reached with the existing router or range extenders. Unlike repeaters or range extenders that rebroadcast existing Wi-Fi signals, a network extender connects directly with the main router using a coax cable. Wi-Fi network extenders provide the most consistent and reliable high-speed Wi-Fi connections. A Wi-Fi network extender can solve issues related to insufficient signal strength. With wireless repeaters and range extenders, incoming signal strength can be challenging. Unlike wireless repeaters that rebroadcast on the same channel as the original signal, range extenders can rebroadcast on a different channel if that provides superior signal coverage. Wireless range extenders also receive the signal from the main router and rebroadcast it. The signal is rebroadcast on the same wireless channel as used by the router but has increased latency. They are just signal repeaters that rebroadcast the Wi-Fi signal to a finite localized area. Wireless repeaters are the simplest solution. It looks at uses for band steering and Wi-Fi mesh networks and closes with using Wi-Fi heat maps for more effective network planning and deployment. This FAQ briefly reviews several of them, including wireless repeaters, range extenders, and network extenders. There are several options for extending Wi-Fi signals, including hardware and network architecture options. When working to extend Wi-Fi signals, the bidirectional nature of the connection is an important factor. Wi-Fi connections are always bidirectional and symmetrical. But transmit power is only half of the equation. Federal Communications Commission (FCC) limits Wi-Fi transmitter power, it’s often necessary to increase the range of Wi-Fi signals using some signal boosting/extending technology. ![]()
