海外TECH	Engadget	The best mesh Wi-Fi systems of 2024	https://www.engadget.com/best-mesh-wifi-system-130028701.html?src=rss	Having a strong home Wi Fi signal that doesn t drop out on you is crucial for a seamless and productive lifestyle Whether you re working from home streaming your favorite shows or have a small army of smart home devices a reliable internet connection has become essential to keep it all running Traditional routers often struggle to cover every corner of your house especially if your home has thick walls or multiple floors This is where mesh Wi Fi routers come to the rescue offering a robust solution to extend Wi Fi coverage throughout your entire home Mesh Wi Fi routers work by using multiple nodes placed strategically around your home to create a unified and extensive home network These systems are designed to ensure that you have a strong Wi Fi signal in every room eliminating dead zones and offering consistent performance We ve tested numerous mesh systems for connection reliability coverage ease of setup and additional features like parental controls To help you decide and take the hassle out of choosing we ve put together a list of the best mesh Wi Fi systems available today If you re looking to boost your existing Wi Fi network and don t want to invest in a new Wi Fi system check out our top picks for the best Wi Fi extenders instead Wi FiWi Fi is governed by the International Standard IEEE and every few years the standards evolve Until routers were sold under their IEEE designation leaving consumers to deal with the word soup of products labeled b a g n ac et cetera Mercifully wiser heads opted to rebrand the standards with numbers Wi Fi Wi Fi and Wi Fi We re presently between two Wi Fi generations Wi Fi and E which relates to the frequencies the standard uses Wi Fi covers routers which operate on the GHz and GHz bands while the latter means it can also use the GHz band Each Wi Fi band has tradeoffs because the slower radio frequencies have greater range but less speed GHz signals will travel a long way in your home but aren t quick while GHz is blisteringly fast but can be defeated by a sturdy brick wall A lot of Wi Fi enabled gear like a lot of smart home products only use GHz because the range is better and it s a lot cheaper But it means that the band is also overcrowded and slow Linksys CEO Jonathan Bettino told Engadget why mesh systems are an advancement in Wi Fi technology over buying a single point router With one transmitter the signal can degrade the further away from the router you go or the local environment isn t ideal You can have a small home but there s thick walls or things in the way that just interfere with your wireless signal he said Historically the solution to a home s Wi Fi dead zone was to buy a Wi Fi Range Extender but Bettino said the hardware has both a terrible user experience and one of the highest return rates of any consumer electronics product Mesh Wi Fi by comparison offers multiple nodes that can be placed anywhere in your home says Bettino resulting in ubiquitous Wi Fi that feels as if you have a router in every room Rather than having one main router in your home having a router in every room is the biggest selling point for mesh Wi Fi given how reliant we all are on the internet Each node is in constant contact with each other broadcasting a single seamless network to all of your connected devices There s no separate network for the GHz and GHz bands just a single name that you connect to You may also see mesh Wi Fi systems advertised as dual band or tri band routers Dual band routers typically offer a GHz and GHz band Wi Fi E tri band routers on the other hand provide a GHz a GHz and a GHz band ーor in the case of Wi Fi or Wi Fi routers a GHz band and two GHz bands Once you ve got your head wrapped around the concept of dual band and tri band you should also be aware that the width of each band is measured in MHz The wider the band the more MHz it can support typically MHz MHz MHz MHz or MHz The wider the channel the more bandwidth it offers What to look forIt s a pretty good time to buy a mesh Wi Fi system since Wi Fi E represents a fairly significant leap in the technology Matt MacPherson Cisco s Chief Technology Officer for Wireless said that Wi Fi E is a substantial inflection point and can take advantage of a much broader chunk of the wireless spectrum than its predecessors If you re using that spectrum with a Wi Fi device he said you re going to get significant gains in speed MacPherson added that Wi Fi E will likely carry you for a long time thanks to the fact that its top throughputs now typically exceed what people can actually connect their home to In short with a top theoretical per stream speed of Gbps Wi Fi E is fast enough to outrun all but the fastest internet connection You may also see talk of Wi Fi devices some of which have been released already before the standard is officially launched next year Given that it will take a generation for all of the devices in your home to be compatible with Wi Fi it s not worth thinking about this for several years yet Range and speedAll mesh routers boast a theoretical broadcast range in square feet as well as its theoretical top speed Given there are so many factors outside of the manufacturer s control these numbers don t really mean much in the real world Your internet provider s real speed the construction materials and layout of your home amongst other things will all affect your Wi Fi coverage Simply investing in a wireless router or mesh Wi Fi system isn t going to offer faster speeds on its own It s worth saying that raw speed isn t everything and that for most normal users you probably need a lot less than you re paying for Netflix recommends a minimum speed of just Mbps to stream a K video to a single device Naturally that s just for one connection so you ll need some more capacity if you ve got other connected devices all running at the same time As cool as it is to say you ve got or Mbps download speed factors like latency and reliability are way more crucial BackhaulMesh Wi Fi systems work by connecting every hardware node to a single wireless network letting them all communicate with each other Imagine four people in a busy noisy restaurant all trying to order their dinner from a weary staff member all at once Now imagine while this is going on that four more people at that same table are also trying to tell a funny anecdote It s no surprise that it might take a long while for the right information to reach its intended destination To combat this higher end mesh routers offer dedicated wireless backhaul a slice of the spectrum for node to node communication So rather than everyone talking at once in the same space the conversations are essentially separated reducing the invisible clutter in the air Because there s less confusing cross chatter everything moves faster offering a significant performance boost to those systems ConnectivityThese days even your washing machine has a wireless connection but that doesn t mean you should ignore the joys of wired internet No matter how fast WiFi is a hard line will always be faster and some gear like Philips Hue bridge still needs an ethernet connection Plenty of routers can also use these hard connections as backhaul eliminating further wireless clutter It s convenient for spread out systems and power users but it will mean running more wires through your home The most common standard is Cat e or gigabit ethernet which unsurprisingly has a top speed of Gigabit per second Gbps Since Ethernet cables are backward compatible you should be able to easily find one that works with your system However to make the most out of your mesh routers it s worth investing in an Ethernet cable that meets the standard your router uses ーif it s Cate use a Cate cable Flexibility and scalabilityMesh routers enable you to add or subtract modules from your home network to suit your needs D Link s Alan Jones said users should check how scalable the prospective product is before you buy This sense of scale doesn t just apply to the number of nodes on the network but how many simultaneous connections it can handle PlacementMesh networks use multiple access points in order to create a bigger network resulting in better indoor Wi Fi coverage Modern mesh routers offer one two or three or more pieces of equipment that are commonly the same hardware inside and out It normally doesn t matter which module you make the primary one to connect to your modem usually over ethernet You ll then set up the other secondary nodes around your home which is often just a case of adding them to the existing mesh network When installing your hardware remember that every physical obstacle between nodes may hurt your performance The ideal spot is at the very least at waist height on a piece of furniture without too many obstructions Tables sideboards free standing cupboards and bookcases make for a good home The rule of thumb is to place each node no more than two rooms away from the last one How we test Wi Fi routersMy home covers around square feet across three stories with my office on the third floor It s relatively long and thin with the living room at the front of the house the kitchen at the back and three bedrooms on the second floor Its age means there are a lot of solid brick walls old school lathe and plaster as well as aluminum foil backed insulation boards to help with energy efficiency There are two major Wi Fi dead zones in the house the bathroom and the bedroom behind it since there s lots of old and new pipework in the walls and floors For mesh routers that have two nodes I placed the first in my living room connected via ethernet to my cable modem with the second on the first floor landing in the ostensible center of the house For three node sets the third went in my kitchen which I ve found is the optimal layout to get the bulk of my house covered in Wi Fi Each mesh is judged on ease of setup Wi Fi coverage reliability speed and any additional features I looked at how user friendly each companion app is from the perspective of a novice as well My tests included checking for dead zones moving from room to room to measure consistency and streaming multiple videos at once Best mesh Wi Fi systems for Other mesh Wi Fi router systems we testedAmazon Eero EOn one hand Eero Pro E does count as an easy device the sort you could hand to a total novice and expect them to thrive with There s very little brain work needed to get things set up and the app has a clean UI with plenty of hand holding But ーand it s a big but ーthe fact so many common management tools aren t available to me here because they re paywalled irks me Amazon and Eero are playing in the same slightly shallow waters as Google Nest building a good enough mesh product for quot everyone types who want to set up the hardware and more or less forget about it for several years at a time knowing that everything is in hand But the fact that the Nest WiFi Pro offers more features for free compared to Eero s package means that despite my gripes about Google s system it wins out in a straight duel Netgear Orbi The Orbi T RBKE is Netgear s flagship mesh WiFi product which the company calls the world s most powerful WiFi E system It s also one of the most expensive consumer level kits on the market setting you back for a three pack It s a fantastic piece of gear but it s worth saying that the subset of people who could would or should buy it remains far smaller than you might expect Ultimately I feel that if you re paying luxury prices you should expect a luxury product There were plenty of times during testing that I went looking for a feature that was either only available via the web client or behind a paywall While yes much of your cash is going to the superlative hardware but for this sort of money the fact you have to pay extra for some table stakes features is insulting If you re looking for a new Wi Fi system and aren t prepared to spend almost it s worth considering our other top picks
