How Wi-Fi Works

Wi-Fi is internet that is broadcast wirelessly using radio signals. Routers or Wireless Access Points (abbreviated as WAPs) transmit radio signals which are received by devices. These devices can then use this signal as a gateway to access the internet.

Because we need to broadcast the same internet network over many different buildings, MVNU uses a network of many WAPs (492 on the main campus alone) spread over the campus both inside and outside of buildings.

Bands and Channels

Wi-Fi is broadcast using radio waves. Radio waves can be broadcast at different frequencies, which are measured in gigahertz (abbreviated as gHz). Different frequencies can be divided into categories known as bands. Bands can then be divided into smaller categories known as channels.

Wi-Fi can be broadcast on two different bands, 2.4 GHz and 5 GHz, which use different radio frequencies. WAPs at MVNU broadcast on both bands simultaneously.

Each band has a limited usage capacity and can only transmit a certain amount of data at once over a single network.

Each band is broadcast on different channels. 2.4 GHz is broadcast on only 3 channels: 1, 6, and 11. 5 GHz uses about 8 different channels.

One of the main reasons to broadcast on different bands and channels is to prevent different signals from clashing. When two different devices are broadcasting a signal on the same channel, the signals will become distorted because they are interfering with one another, which can cause Wi-Fi issues.

If you are experiencing an issue because of nearby interference, you may be having difficulty getting a strong internet signal even when you are very close to a WAP.

Mesh Networks and Roaming

MVNU uses a mesh network, which means that we have many Wireless Access Points scattered over a large area which are transmitting Wi-Fi on the same network. This is different from the Wi-Fi in most people’s homes, which is usually broadcast from a single access point called a router.

MVNU’s network is designed to provide Wi-Fi by having a device connect to the closest WAP with the strongest signal. In cases where there are many people using the same WAP, that WAP may shift some internet traffic to nearby WAPs with good signals, to keep the usage from slowing down the internet.

When moving from place to place, devices will switch from one WAP to another depending on which is closer and has the best signal using a function called roaming. Ideally, a device with well-functioning roaming should ensure that you always have the best possible signal and the fastest possible connection. Some devices may have problems with their roaming function, which can cause connection issues.

If your device has roaming problems, it may appear to have difficulty connecting to the Wi-Fi in certain buildings or areas of campus, or may lose or drop your Wi-Fi signal, especially when you are walking around campus.

Ethernet

Ethernet is internet that is transmitted over a wired connection. It is often more reliable than Wi-Fi, especially on a network that covers a large area or has many users. Since it eliminates problems such as poor wireless signals or interference, we recommend using it for a more stable wireless connection.

Ethernet is especially ideal for stationary devices such as televisions and gaming consoles. Devices used for streaming content will usually function much better over an Ethernet connection. It is also ideal for computers, both desktops and laptops, especially for things that require a constant and stable internet connection, such as taking exams on a secure browser like LockDown.

MVNU has ethernet ports throughout campus, in academic areas, and in every dorm room and apartment. Ethernet cables are available for free at the Hub in several different lengths. Cords can also be made in custom lengths if needed.

Many devices will have an Ethernet port built in. For those that do not, an adapter can be used to connect to Ethernet through a different port such as a USB port. Ethernet adapters are available for check-out at the Hub.

An Ethernet port on a device will look like this.
