It’s the rare customer these days that still only has a wired connection to a computer and almost the whole residential market has shifted to WiFi. As I have covered in a number of blogs, there are numerous reasons why WiFi is not the greatest distribution mechanism in many homes. I could probably write three of four pages of ways that WiFi can be a problem, but here are a few examples of WiFi issues:
- Customers (and even some ISPs) don’t appreciate how quickly a WiFi signal loses strength with distance. And the losses are dramatically increased when the signal has to pass through walls or other impediments.
- Many homes have barriers that can completely block WiFi. For instance, older homes with plaster walls that contain metal lathe can destroy a WiFi signal. Large heating ducts can kill the signal.
- Most ISPs place the WiFi router at the most convenient place that is nearest to where their wire enters the home. Most homes would benefit greatly by instead placing the router somewhere near the center of the house (or whatever place makes the most sense with more complicated floor plans). Customers can make things worse by placing the WiFi router in a closet or cupboard (happens far too often).
- There are a lot of devices today, like your cellphones, that are preset to specific WiFi channels. Too many devices trying to use the same channels can cause havoc even if there is enough overall WiFi bandwidth.
- A WiFi network can experience the equivalent of a death spiral when multiple devices keep asking to connect at the same time. The WiFi standard causes the transmission to pause when receiving new requests for connection, and with enough devices this can cause frequent stops and starts of the signal which significantly reduces effective bandwidth. Homes are starting to have a lot of WiFi capable devices (and your neighbor’s devices just add to the problem).
A number of ISPs have begun to sell a managed WiFi product that can solve a lot of these WiFi woes. The product often begins by a wireless survey of the home to understand the delivery barriers and to understand the best placement of a router. Sometimes just putting a WiFi router in a better place can fix problems. But there are also new tools available to ISPs to allow the placement of multiple networked WiFi routers around the home, each acting as a fresh and separate hotspot. I live in an old home built in 1923 and I bought networked hotspots from Eero which solved all of my WiFi issues. And there is more help coming in the future, with the next generation of home WiFi routers offering dynamic routing between the 2.4 and 5 GHz WiFi spectrum to better make sure that devices are spread around the usable spectrum.
But managed WiFi alone will not fix all of the customer bandwidth issues. A surprising number of ISPs are not properly sizing bandwidth to meet customer’s needs. Just recently I met with a client who still has over half of their customers on connection speeds of 10 Mbps or slower, even though their network is capable of gigabit speeds. It is a rare home these days that will find 10 Mbps to always be adequate. One of my other clients uses a simple formula to determine the right amount of customer bandwidth. They allow for 4 Mbps download for every major connected device (smart TV, laptop, heavily used cellphone, gaming device, etc). And then they add another 25% to the needed speed to account for interference among devices and for the many smaller use WiFi devices we now have like smart thermostats or smart appliances. Even their formula sometimes underestimates the needed bandwidth. But one thing is obvious, which is that there are very few homes today that don’t need more than 10 Mbps under that kind of bandwidth allowance.
It’s easy to fault the big cable companies for having lousy customer service – because they largely do. But one thing they seem to have figured out is that giving customers faster speeds eliminates a lot of customer complaints. The big cable companies like Comcast, Charter and Cox have unilaterally increased customer data speeds over the past few years. These companies now have base products in most markets of at least 50 Mbps, and that has greatly improved customer performance. Even customers with a lousy WiFi configuration might be happy if a 50 Mbps connection provides enough bandwidth to push some bandwidth into the remote corners of a home.
So my advice to ISPs is to stop being stingy with speeds. An ISP that still keeps the majority of customers on slow data products is their own worst enemy. Slow speeds make it almost impossible to design an adequate WiFi network. And customers will resent the ISP who delivers poor performance. I know that many ISPs are worried that increasing speeds will mean a decrease in revenue – but I find many of those that think this way might be selling six or more speeds. I’ve been recommending to ISPs for years to follow the big cable companies and to set your base speed high enough to satisfy the average home. A few years ago I thought that base speed was at least 25 Mbps, but I’m growing convinced that it’s now more like 50 Mbps. It seems like the big cable companies got this one thing right – while many other ISPs have not.
