Which of the following is the reason for adopting 5G priority access?

Question

Options

• AIt is easier to plan the network in the 5G frequency band
• B5G frequency band can provide better access capability and capacity
• CThe connection speed between users and APs in the 5G frequency band is very fast
• DThe transmission rate of the 5G frequency band is higher than that of the 2.4G frequency band

• A
  3% (1)
• B
  83% (30)
• C
  3% (1)
• D
  11% (4)

Explanation

Option B is correct because the 5GHz band offers more non-overlapping channels and suffers far less interference than the congested 2.4GHz band, which together give it superior capacity to serve more devices simultaneously and with greater reliability - this is precisely the goal of priority access schemes.

Option A is wrong because 5GHz planning is actually more difficult, not easier: its shorter propagation range and reduced wall penetration require more access points and more careful placement. Option C is misleading because connection speed between users and APs is a result of better capacity, not the stated rationale for adopting priority access; it also conflates speed with the broader concept of access capability. Option D is incorrect as a standalone reason because, while 5GHz can offer higher peak transmission rates, that fact alone does not explain priority access - some 2.4GHz devices can also achieve high rates, and raw speed misses the capacity and interference advantages that B captures.

Memory tip: Think of 5GHz as a wider road with more lanes. Priority access sends traffic there because it can handle more vehicles (devices) with less congestion - that is capacity and access capability, which is exactly what option B describes.
