The correct answer is 4G. 4G refers to the fourth generation of wireless cellular technology. It provides faster internet speeds and better connectivity compared to its predecessors, 3G and 2G. In Indonesia, 4G technology is the latest and most advanced wireless cellular technology available, allowing users to access high-speed internet and enjoy various online activities seamlessly.

The correct answer is "Butuh banyak kabel". This answer is correct because one of the advantages of wireless network topology is that it does not require a lot of cables. Unlike wired networks, wireless networks use radio waves to transmit data, eliminating the need for extensive cable installations. This allows for easier and more flexible installation, as well as high mobility as devices can connect to the network without being physically connected to it.

Scanner is not a client device that can receive signals from an access point. Scanners are used for scanning physical documents and converting them into digital format, they do not have the capability to connect to a wireless network and receive signals from an access point. On the other hand, HP, PC, and Laptop are all client devices that can connect to a wireless network and receive signals from an access point.

The correct answer is Hertz. Hertz is the unit used to measure frequency. It represents the number of cycles or oscillations per second in a wave or signal. It is commonly used in fields such as physics, electronics, and telecommunications to quantify the rate of repetitive events. Meter is a unit of length, Watt is a unit of power, and Volt is a unit of electrical potential difference.

Overlapping gelombang mengacu pada fenomena ketika dua atau lebih gelombang bergerak melalui medium yang sama dan berpotongan satu sama lain. Pada saat ini, amplitudo gelombang dapat saling menambah atau saling mengurangi, tergantung pada fase relatif gelombang-gelombang tersebut. Fenomena ini dapat terjadi dalam berbagai jenis gelombang, seperti gelombang suara, gelombang air, atau gelombang elektromagnetik. Overlapping gelombang adalah dasar dari banyak fenomena fisika, termasuk interferensi dan difraksi.

Omni Directional antennas are designed to radiate signals in all directions, covering a complete 360-degree area. This type of antenna is commonly used in scenarios where the signal needs to reach multiple devices or cover a large area, such as in Wi-Fi networks or broadcasting systems. Unlike Directional, Yaggi, or Parabolic antennas, which have a specific direction or focus, Omni Directional antennas provide a more widespread coverage pattern, making them suitable for applications requiring a broad transmission range.

Ad-hoc is the correct answer because it refers to a network that consists of two or more wireless devices communicating directly with each other. This type of network does not require any infrastructure or centralized control, as the devices can connect and communicate with each other on the fly. It is commonly used in situations where a temporary or spontaneous network is needed, such as in ad-hoc meetings or emergency situations.

The correct answer is Kabel UTP. This is because UTP cables are not a wireless technology. They are used for wired connections in networking, unlike hotspot, Bluetooth, and infrared which are all wireless technologies used for communication and networking.

The given options are different standards for wireless communication. The standards IEE 802.11a, IEE 802.11b, and IEE 802.11g are all different versions of the Wi-Fi standard, each with its own specifications and frequency bands. However, IEE 802.11k is not a standard for wireless communication. Therefore, it is the correct answer as it does not belong to the list of wireless standards mentioned.

Access point berfungsi untuk meneruskan dan memperkuat sinyal nirkabel. Access point bertindak sebagai titik akses atau jembatan antara perangkat nirkabel dengan jaringan kabel. Access point akan menerima sinyal nirkabel dari perangkat seperti laptop atau smartphone, kemudian meneruskannya ke jaringan kabel agar dapat terhubung ke internet atau jaringan lokal. Selain itu, access point juga dapat memperkuat sinyal nirkabel agar dapat mencakup area yang lebih luas dan mengatasi hambatan seperti dinding atau interferensi.

Connecting a mobile phone with a laptop using Bluetooth is an example of a WPAN (Wireless Personal Area Network). WPAN is a short-range wireless network that allows devices to communicate with each other within a limited area, typically within a range of 10 meters. Bluetooth technology enables wireless communication between devices such as smartphones, laptops, and other peripherals, making it suitable for connecting devices in close proximity to each other.

Dalam kegiatan survey perancangan jaringan wireless, salah satu hal yang harus dilakukan adalah menentukan zona atau area yang akan dicakup oleh jaringan tersebut. Zona ini akan membantu dalam menentukan lokasi dan jumlah access point yang dibutuhkan. Oleh karena itu, jawaban yang benar adalah "Zone" karena hal ini adalah salah satu hal yang harus dilakukan dalam kegiatan survey perancangan jaringan wireless.

An external antenna is used to increase the physical range of radio waves in a wireless network. It is connected to the wireless router or access point and helps to improve the signal strength and coverage area. By placing the antenna in a strategic location, it can extend the range of the wireless network and provide better connectivity to devices that are far away or have obstacles in between. This makes the external antenna an essential tool for expanding the coverage area of a wireless network.

The reason why the frequency channels used in each country are different is because of the different regulations in each country. Each country has its own set of rules and regulations regarding the allocation and usage of frequency channels. These regulations are put in place to ensure efficient and effective use of the limited frequency spectrum and to prevent interference between different communication systems. Therefore, the frequency channels used in each country may vary based on their specific regulations.

Wireless IEEE 802.11 b/g/n provides 14 channels. These channels are used for transmitting and receiving wireless signals. Each channel operates on a different frequency, allowing multiple devices to communicate without interference. The availability of 14 channels provides flexibility and helps to reduce congestion in wireless networks.

The correct answer is Grid. Grid antennas are specifically designed for long-distance transmission. They have a high gain and narrow beamwidth, allowing for focused and efficient transmission over long distances. Grid antennas are commonly used in point-to-point communication systems, such as wireless backhaul links or long-range Wi-Fi connections.

The correct answer is 5 GHz because IEEE 802.11a is a wireless standard that operates at this frequency. This frequency band offers higher data rates but shorter range compared to the 2.4 GHz band. It is less crowded and provides better performance in environments with multiple devices.

The correct answer is 802.11. In 1997, the independent organization called IEE created the first WLAN specification with the code 802.11. This specification laid the foundation for the development of wireless local area networks (WLANs) and standardized the communication protocols and frequencies used in wireless networking.

BSS stands for Basic Service Set, which is a type of wireless network topology that requires one Access Point (AP) to act as a base station. In a BSS, multiple devices connect to the AP to access the network. This topology is commonly used in home or small office environments, where a single AP provides wireless connectivity to a limited number of devices within its range. The AP acts as a central hub, managing the network and facilitating communication between the connected devices.

The correct answer is Bridging. Bridging is a function of wireless networks that connects two networks through a link between two interfaces. It allows for the transfer of data between the two networks, enabling devices on one network to communicate with devices on the other network. Bridging is commonly used to extend the range of a network or to connect different types of networks together.
