Mobile phone network

The way a smartphone joins a network through mobile phone towers, so it works without a cable or Wi-Fi, even in places with no Wi-Fi.

Understanding Mobile phone network in ACARA Digital Technologies Years 5–6

What it does: Mobile data works through mobile towers, so the phone can still get online in places with no Wi-Fi. Wi-Fi connects to a nearby router, while mobile data connects to a mobile tower. They are two different ways to join a network. The router at home only reaches a short distance. Mobile towers cover a much wider area.

Common mistakes: A smartphone joins a mobile network, not a wired one. A wired network needs cables. It should be network = mobile_network. There is no Wi-Fi at the campsite, but a mobile tower is in range. The phone connects through the tower using mobile data, so it should be can_connect = tower_in_range.

Quick Questions

1. How does a smartphone join the mobile phone network?

A. Through a mobile phone tower ✓

B. Through a network cable plugged into the phone

A phone sends and receives data by radio signals with a nearby mobile tower. It does not need a cable.

2. Which one lets a phone go online using mobile data?

A. A printer

B. A mobile phone tower ✓

Mobile data connects through mobile towers. A printer is a device that can be on a network, but it does not give a phone mobile data.

3. Your family is driving through the bush and there is no Wi-Fi. Can your phone still go online?

A. No, phones can only go online with Wi-Fi

B. Yes, if a mobile tower is in range, using mobile data ✓

Phones can use mobile data through towers, so they can work in places with no Wi-Fi.

4. Which statement about mobile data is true?

A. It works without a cable or Wi-Fi ✓

B. It only works when you are plugged into a router

Mobile data uses towers instead of a cable or a Wi-Fi router.

5. At the beach, a phone with no Wi-Fi nearby loads a map. What is it most likely using?

A. Mobile data ✓

B. A network cable

With no Wi-Fi and no cable, the phone is using mobile data from a tower.

Match the Pairs

mobile data → Lets a smartphone join a network through a mobile phone tower, with no cable or Wi-Fi needed

mobile tower → A tall structure that sends and receives signals so phones nearby can join the network

On a bush hike with no Wi-Fi, a phone can still join the network through a tower → mobile data ON, Wi-Fi OFF

At home a phone can use Wi-Fi from the router instead of mobile data → Wi-Fi ON, mobile data OFF

A phone needs a Wi-Fi router to use mobile data. → Mobile data does not use a Wi-Fi router. It connects to a mobile phone tower.

Phones with mobile data stop working when there is no Wi-Fi. → Mobile data works in places with no Wi-Fi, as long as the phone can reach a mobile tower.

Key Term

The way a smartphone joins a network through mobile phone towers, so it works without a cable or Wi-Fi, even in places with no Wi-Fi.

Fill in the Blanks

1. phone.join(tower)

Hint: Type the name of the structure that a phone connects to so it can use mobile data.

2. phone.use(mobileData)

Hint: Type the function name that tells the phone to start using a connection.

3. mobileData.needsWifi = false

Hint: Type the true or false value showing that this kind of connection does not need Wi-Fi.

4. if wifi == false: phone.use(mobileData)

5. for place in ["bush", "beach"]: phone.use(mobileData)

Hint: Type the variable name for the connection that still works in places with no Wi-Fi.

Spot the Error

Question 1

A network = wired_network

B device = smartphone

C joins_through = mobile_tower

D needs_cable = false

Line A — A smartphone joins a mobile network, not a wired one. A wired network needs cables. It should be network = mobile_network.

Question 2

A place = bush_campsite

B wifi_available = false

C tower_in_range = true

D can_connect = wifi_available

Line D — There is no Wi-Fi at the campsite, but a mobile tower is in range. The phone connects through the tower using mobile data, so it should be can_connect = tower_in_range.

Question 3

A if connection == mobile_cable:

B use = mobile_tower

C else:

D use = wifi_router

Line A — Mobile data does not use a cable. The phone connects to a mobile tower. It should be if connection == mobile_data:.

Question 4

A tower = mobile_tower

B phone = smartphone

C link = cable(tower, phone)

D print(link)

Line C — A mobile tower and a phone are linked by radio signals through the air, not by a cable. It should be link = radio(tower, phone).

Question 5

A wifi_range = one_building

B tower_range = one_room

C print(tower_range)

Line B — One mobile tower covers a large area, such as many streets. It is not limited to one room. It should be tower_range = many_streets.
