Explanation:
A post-deployment site survey report should also include capacity analysis results to ensure WLAN users experience acceptable performance. The capacity analysis looks at the network's ability to handle the number of clients and the traffic they generate. It is essential to ensure that the WLAN can support the expected number of users and provide sufficient bandwidth for their applications. A post-deployment site survey report with capacity analysis results can help identify capacity limitations and provide recommendations for optimizing network performance.
Explanation:
IBSS (Independent Basic Service Set) is not the best option for creating a wireless link between two buildings on a single campus. IBSS is a wireless network where wireless devices communicate directly without a central access point or infrastructure. In an IBSS network, all devices communicate directly, and the network is not connected to any wired network.
Explanation:
The maximum number of spatial streams that can be used for a downlink HT-OFDM (High Throughput-Orthogonal Frequency Division Multiplexing) transmission from AP-1 to STA-3 is two because the AP is a 3x3:2 AP, which means it is capable of transmitting on two spatial streams. At the same time, the client STA-3 is a 3x3:3 client, which means it can receive up to three spatial streams. The number of spatial streams that can be used for transmission is limited by the lowest number of spatial streams supported by either the transmitting or receiving device, which in this case, is two.
Explanation:
The likely problem is that the laptops lack a 5 GHz capable wireless adapter. If the laptops can only connect to 2.4 GHz APs and cannot even see 5 GHz APs, likely, they are not equipped with a 5 GHz wireless adapter. In this case, the solution would be to either replace the laptops with models with 5 GHz wireless adapters or add external 5 GHz wireless adapters. The fact that other tablets can connect to 5 GHz channels in the same work areas indicates that the issue is specific to the laptops themselves and not a problem with the wireless environment.
Explanation:
DSSS (Direct Sequence Spread Spectrum) is a PHY used in the 2.4 GHz frequency band by the 802.11b standard. It uses a spreading code to spread the data signal over a wider frequency band, which makes it more resilient to interference and noise. However, it does not use any available space in shallow-frequency ranges that are not in use at the time by broadcast video signals.
Explanation:
The best method for implementing network backhaul for communications across the Internet would be to use cellular/LTE technology. Cellular networks are widely available and provide a reliable and secure way to connect remote locations to the Internet. They are also designed to work in disaster situations, often with backup power and other redundancy measures. In contrast, other options, such as satellite or microwave backhaul, may not be feasible due to the remote location and the effects of the natural disaster. Therefore, cellular/LTE technology is the best option for providing reliable backhaul.
