What are the signals that are transmitted to and from wireless electronic devices carried on?
Radiofrequency (RF) Signals:
RF signals are used in various wireless communication technologies, including:
Cellular networks: Mobile phones use RF signals to communicate with cell towers.
Wi-Fi (Wireless Fidelity): Wi-Fi devices, such as smartphones, laptops, and routers, use RF signals to connect to local wireless networks.
Bluetooth: Bluetooth-enabled devices, like headphones, speakers, and smartphones, use RF signals for short-range wireless connections.
Zigbee: Zigbee is a wireless communication protocol commonly used in smart home devices like smart lights, thermostats, and sensors.
NFC (Near Field Communication): NFC technology allows devices to exchange data over very short distances, often used for contactless payments and device pairing.
Infrared (IR) Signals:
Infrared signals are used for short-range communication between devices that have IR transmitters and receivers. TV remote controls are a common example of devices that use IR signals.
GPS Signals:
Global Positioning System (GPS) devices receive signals from multiple satellites to determine their precise location and provide navigation information. GPS signals are crucial for location-based services and navigation applications.

It depends on the antenna you are using. Without going into great detail about propagation, interference, and other factors to get the most range out any frequency you need a good antenna. The antenna of choice would be a directional antenna with a narrow beam-width. These using come in the form of a grid or parabolic dish. These particular types of antennas do a good job of focusing the radiated energy for the maximum distance or range. In a point to point setup with clear line of site, low interference, and clear Fresnel zone one could reach over 30+ miles.
Actual data throughput is usually higher on wireless networks?

Short answer is that 'dropped packets' happens when the network is unstable so not all of the information sent out by you is received at the other end. One reason you have 'unreachable host' is the host computer is switched off. There are other reasons but making the network more reliable is the best solution

What makes the star topology better than the other networks?
Star topology is the simplest and most comprehensible example of a centralized network there is. In star topology, all of the computers, printers, security feeds, etc., etc. that use the network are connected to a centralized hub, rather than to each other, in a star-like shape. The main advantage of this is that if one device goes down, the others stay up.
The obvious disadvantage of this is the network's dependence on the hub; if it fails, everything fails. Many chain-store type business's, much to the frustration of their employees, have actually turned this disadvantage into an advantage. Instead of spending money on quality devices at the store level, the business's put all of their money into the hub, then add a backup hub as a fail safe, and then finally an off-site disaster recovery hub for emergencies.
Which brands of USB wireless network adapters receive the best reviews?
