Things to look for when buying a Wi-Fi router

Posted on Friday January 08, 2021

A strong network enables your business to surf the web and access cloud productivity apps. Behind these networks are Wi-Fi routers that keep your devices connected to the internet. While there are many more components involved in setting up a strong network, your choice of router can make a huge difference. Here are some tips to help you find the right router for your business.

Network type

Look at any router and you will quickly see that there are a number of different network types available. Also referred to as wireless protocols, the four most common types are 802.11b, 802.11g, 802.11n, and 802.11ac. These designations indicate how fast the router can transfer wireless data, with 802.11ac being the fastest.

Newer routers now utilize the latest Wi-Fi protocol dubbed 802.11ax. Also known as Wi-Fi 6 or High-Efficiency Wireless (HEW) , this new protocol improves upon 802.11ac tech in the following ways:

• Greater throughput speeds (up to 9.6 Gbps)
• Reduced network congestion and expanded client capacity, thanks to Orthogonal Frequency-Division Multiple Access (OFDMA)
• Improved range performance
• Reduced power consumption by network-connected devices, courtesy of Target Wake Time (TWT)

OFDMA enhances network performance by splitting up Wi-Fi channels into sub-channels. Doing so permits up to 30 users to use the same channel simultaneously.

TWT reduces the power consumption of connected devices by allowing them to determine when and how often they will wake up to begin sending and receiving data. This extends the battery life of smartphones and battery-powered internet of things (IoT) home devices such as smart thermostats and security cameras.

Throughput

In communication networks, throughput is the rate at which messages are successfully delivered via a communications channel. A router's throughput, in particular, is the speed at which the router is supposed to transmit data from your connection to users. To spot the router's throughput, look for Mbps (or Gbps for its cable ethernet connections). It is usually one of the first things listed on router boxes and specifications.

Keep in mind that if you have a 100 Mbps internet connection, but your router can only deliver up to 80 Mbps, then the total speed of your network will be the lower figure. Therefore, it would be best to get a router with a higher throughput if your internet service provider delivers faster connections.

Bands

On every single router's box, you will see numbers like 2.4 Ghz and 5 Ghz. These indicate the wireless radios on the router. A dual- or tri-band router will have both radios so that the connection workload can be split between them.

The 2.4 Ghz radio is sufficient for activities that don't require much network bandwidth, such as web browsing and replying to emails. Since its band is of a lower frequency, it reaches farther than 5 Ghz but is more easily blocked by concrete walls.

The 5 Ghz band, on the other hand, has greater power, but has a shorter broadcast range. 5 Ghz is what you'll want to use for video conferencing and playing online games (if permitted by the company after office hours, of course).

Multiple input, multiple output (MIMO)

MIMO is the use of multiple antennas to increase performance and overall throughput. MIMO-enabled routers ensure that more devices can connect to one router with less interference.

When it comes to real-world tests, there is often a slight improvement if the antennae are configured and aimed properly. However, getting a high-end router with six or more antennae may be an unnecessary cost for small businesses.

Beamforming

Beamforming is a feature that's now standard in mid- to high-end routers. It is a form of signal technology that allows for better throughput in areas with poor or dead signals. In other words, it can help improve the connection quality with devices behind solid walls or in rooms with high amounts of signal interference.

By utilizing this technology, routers can see where connections are weak and act to improve it. While this is available on routers with many network types, it is really only useful with routers running 802.11ac or higher. Those who don't mind paying a higher price point for an increase in network performance should consider this feature.

Quality of service (QoS)

QoS allows the router administrator to limit certain types of traffic. For example, you can use the QoS feature of a router to completely block all torrent traffic, or limit it so that other users can have equal bandwidth. Not every router has this ability, but it is a highly beneficial feature for office routers.
