In this class, we will be looking at four things that you might wish to purchase at some point. This will include:
· Routers
· Digital media receivers for your car.
· Video doorbells.
· Smartwatches.
We will introduce these devices and will then give you time to search for those devices which you would find most useful. We will also provide you with a checklist for each of these products, so that you can determine which is best.
We are using Best Buy as a guide. I chose this because you can look at products online and you can also go to the store. Keep in mind you can use any other online stores for these devices. I often use Amazon to purchase technology. But many people prefer to go in person to see what is available.
Routers
Routers
There are two types of hardware needed to distribute the signal within your home. They are a modem and a router. You may also have a combination modem/router instead. Already have a modem provided by your Internet service provider, Then you will be looking for a standalone router. Otherwise, you will look for a combination modem router.
Options: Mesh versus Traditional router:
• Mesh networks are multiple devices (nodes) that are placed around house. The main node is connected via an ethernet cable. Devices work together to provide the best network.
• Traditional router: An advantage is that it comes with ports that can use ethernet to connect. Good for gaming and desktop computers.
If your home is large or has lots of obstacles (more on that in a bit), you may prefer the mesh router. In this case, you plug the hub (main node) into the modem, preferably near the center of your home, and you can move the other nodes into different locations until you have found good connections without dead spots.

Other products to improve Wi-Fi signals:
• Range Extender: A range extender is a device that you can plug into an outlet and extend the signal. However, it is only as good as the signal at that point. They do have limitations, including the speed of the Internet connection coming into your home, the distance from the router, the areas of your home needing Wi-Fi coverage and the needs of your household. It works by plugging it into a point midway between the router and the dead-zone area. It relies on the same frequency band as the router, which can reduce the speed by about half. A router with 50 Mbps speed will have only 25 Mbps through the extender. The mesh routers use two different frequency bands, which keeps the speed loss at roughly 10%.
• Access Point: An access point is a device that creates a wireless local area network (or WLAN). They are usually used in an office or large building. An access point connects to a wired router, switch or hub via an Ethernet cable, and projects a Wi-Fi signal to a designated area. They can handle many connections at once. In home use, they may be used to create Internet outside your home.

What to look for in the router:
• A brand-new technology: 802.11ax (Wi-Fi6). This replaces 802.11ac (Wi-Fi 5) and 802.11n (Wi-Fi 4). These are standards which involve speed, range and support for connected devices. Only a few devices can connect to a Wi-Fi 6 network to take advantage of the speed. For most, Wi-Fi 5 will be adequate. However, if you are buying a new one, you might as week get the newest standard.
• Dual-band vs Tri-band: A dual band router allows two different frequencies or bands. They are usually 2.4 GHz and 5 GHz. There are more devices using 2.4 GHz but is significantly slower than 5 GHz. But a problem with the 5 GHz channel is that the range is limited. A tri-band Wi-Fi router has the 2.4 GHz channel and two 5 GHz channels. These are provided in case one of the 5 GHz is already being used. A dual band router is sufficient for most home uses (streaming, online gaming), while the tri band router is better suited for larger spaces like offices, apartments or hotels.
• DOCSIS 3.1: This is the technology available since 2013. Prior to that, it was DOCSIS 3.0. The new technology is speedier (supports up to 10 Gbps), increases uplink speed for critical uploads, improves stability and reliability of your Internet, energy efficient
• Channels and channel bonding: Uploading and downloading take place on different channels, as do transmissions at different speeds (2.4 GHz vs 5 GHz). Having multiple channels will decrease risk of traffic jams on the network.
• Firewall: Most routers have a built-in firewall. In addition, a software firewall is built into most operating systems.
• LAN ports: LAN ports (local area network) are used to connect the computer or devices to the router using an Ethernet cable. Many Internet-connected home devices require a LAN port-connected hub to run. If you need more ports, you can add an Ethernet switch, which opens more ports.
• USB ports are used to connect to a flash drive, an external hard drive or a USB printer if the router has a built-in print server.
• Rent or buy? The ISP might provide you with a router and you will pay a monthly fee. However, if you choose to buy your own, you have more say in the operation and security of your home Wi-Fi network. You can use a mobile app to set up the router. You can set up parental controls and a guest network as well.
