Vi bruker sambandsradioen så snart køsystemet stopper.

Because Norwegian usually writes compound nouns as a single word.

So:

• samband = communication, connection, signal contact
• radio = radio

Together, sambandsradio means something like communications radio or two-way radio.

This is very common in Norwegian. Where English often uses separate words, Norwegian often joins them:

• køsystem = queue system
• togstasjon = train station
• sykehuslege = hospital doctor

So sambandsradioen is not unusual at all; it is just a compound noun in its definite form.

Those endings show the definite form, and they depend on the noun’s gender.

• en sambandsradio → sambandsradioen
• et køsystem → køsystemet

So:

• -en is the usual definite ending for common gender nouns
• -et is the usual definite ending for neuter nouns

In English, you would use the as a separate word. In Norwegian, the definite article is usually attached to the end of the noun.

So instead of the communications radio, Norwegian says sambandsradioen.

Because the noun is already definite.

In Norwegian, the definite article is usually added as a suffix:

• en radio = a radio

• radioen = the radio

• et system = a system
• systemet = the system

So sambandsradioen already means the communications radio, and køsystemet already means the queue system.

A separate word like den or det can appear in some contexts, but it is not needed here.

Så snart is a fixed expression meaning as soon as.

It is not just så plus snart in a literal word-by-word way in this sentence; together they function as a conjunction introducing a time clause.

Examples:

• Vi drar så snart han kommer. = We leave as soon as he arrives.
• Ring meg så snart du kan. = Call me as soon as you can.

So in your sentence, så snart køsystemet stopper means as soon as the queue system stops.

Because Norwegian often uses the present tense for future meaning, especially when the future is understood from context.

That is very normal in sentences like this:

• Vi bruker sambandsradioen så snart køsystemet stopper.
• literally: We use the communications radio as soon as the queue system stops
• natural meaning: We will use the communications radio as soon as the queue system stops

This is especially common in:

• planned actions
• scheduled events
• time clauses after words like når, så snart, før, etter at

English also does something similar in the time clause:

• We will use it as soon as the system stops not
• We will use it as soon as the system will stop

So the Norwegian structure is very natural.

Because vil is often unnecessary when the future is already clear.

Norwegian can express future time simply with the present tense:

• Jeg kommer i morgen. = I am coming tomorrow / I will come tomorrow.
• Vi bruker sambandsradioen så snart køsystemet stopper. = We will use the radio as soon as the system stops.

You could use vil in some sentences, but it often adds a sense of intention, willingness, or prediction rather than just simple future time.

Here, plain present tense sounds more natural.

Yes, the word order is normal.

Så snart introduces a subordinate clause, and in that clause the usual order is:

• conjunction + subject + verb

So:

• så snart køsystemet stopper

not

• så snart stopper køsystemet

The second version sounds wrong in standard Norwegian.

This is an important contrast with main clauses, where Norwegian often has verb-second word order. But after a subordinating conjunction like så snart, at, fordi, når, hvis, the subject usually comes before the finite verb.

Sometimes yes, but the meaning is slightly different.

• så snart = as soon as
• når = when

Så snart emphasizes immediacy: the radio will be used immediately after the system stops.

Når is more neutral and can simply mean when.

So:

• Vi bruker sambandsradioen så snart køsystemet stopper.
  = We use it immediately once the system stops.

• Vi bruker sambandsradioen når køsystemet stopper.
  = We use it when the system stops.

In many contexts both are possible, but så snart is more precise if you want the idea of immediately after.

The dictionary forms are:

• å bruke = to use
• å stoppe = to stop

The forms in the sentence are present tense:

• bruker = use / are using / will use
• stopper = stops / is stopping

For many Norwegian verbs, the present tense is made by adding -r to the infinitive:

• bruke → bruker
• stoppe → stopper

So this sentence is grammatically very straightforward in terms of verb forms.

Because stopper is a finite verb, not an infinitive.

In Norwegian:

• å stoppe = to stop
• stopper = stops / is stopping

Here, køsystemet stopper is a full clause:

• køsystemet = subject
• stopper = finite verb

So å would be wrong here. You only use å with the infinitive, like to in English:

• Det kan stoppe. = It can stop.
• Det begynner å stoppe. = It begins to stop.

But in your sentence, the system itself is doing the action in a normal clause, so stopper is correct.
