Please reply to following 2 posts. Reply means read post and provide a reply what is written. Clearly identify your replies (which reply is for which post) in your submission. Please make your reply posts substantive. A substantive post will do at least two of the following:· Ask an interesting, thoughtful question pertaining to the topic· Answer a question (in detail) posted by another student or the instructor· Provide extensive additional information on the topic· Explain, define, or analyze the topic in detail· Share an applicable personal experience· Provide an outside source (for example, an article from the UC Library) that applies to the topic, along with additional information about the topic or the source (please cite properly in APA)· Make an argument concerning the topic.At least 1 (scholarly) journal source should be used for each reply. Be your references in correct APA 7 format and cite each reference at least once, but as many times as you rely on it. Citations support each sentence relying on a reference, not an entire paragraph. Do not use direct quotes, rather rephrase the author’s words and continue to use in-text citations.Reply to each post needs to be 250 words minimum, with separate journal referencePost1:Technologies which has been used in order to maximize the radio frequency are basically divided into 3 types and each one has its sub types :long range : when then radio waves has to be send over a very long distance then we have cellular network which often have radio wave traveling to a large distance which are offend transferred from one network to the other depending on their receivers point (Acosta, 2019).sigfox :which use low data transmission rate and successfully avoid network interferences and ensure data transfer integrality. Satellite which through the help of uplink and downlink transfer the data which offers a high rate of data transmission (Acosta, 2019).medium range : we have wifi(transfer larger amount of data with good bandwidth ) and zig bee ( self-healing, secure, robust, and mesh-capable protocol)Protocols that wireless devices use to maximize their use of the available radio frequencies:-ZigBee (IEEE 802.15.4) – ZigBee offers 128 bit AES encryption. We see Zigbee in mesh topology based networks where all networks get connected through multiple pathways. The application of this protocol can be seen in home based IoT devices (Bhargava, 2019).Wifi (IEEE 802.11) – WiFi works on radio based frequencies. This protocol is used in networks where routers are used to connect with computers or two or more hardware components. It can utilize 2.4GhZ UHF and 5GhZ SHf ISM bands. There are three protocols 802.11b, 802.11g, and 802.11n which are used by 2.4Ghz (Bhargava, 2019).Bluetooth and BLE (IEEE 802.15.1) – For shorter distance data transfer we use bluetooth or BLE ( Bluetooth Low Energy) Protocol.For small devices like mobile phones, Laptops and Tablets, this technology is successful.Bluetooth uses UHF RF for data transfer (Kong, 2019).WiMax ( IEEE 802.16) – Worldwide Interoperability for Microwave Access (WiMax) is used by several mobile careers to transfer data at the speed of 30-40Mbps. This technology is successful for both indoor and outdoor use (Kong, 2019).There are various secure methods used to secure wireless devices and networks which are WEP, WPA and WPA2. WEP is considered as the most unsafe technology to use as a secutity as it uses unencrypted mechanism. WPA is secured and WPA2 is considered as the most secured encryption method as it provides security at more levels (Kong, 2019).Post2:Wireless technology has evolved to a whole new level. Over the last couple of years, technology has advanced in different aspects such as capabilities and design. More specifically, wireless technology has advanced with the development of Radio Frequency (RF) communication gadgets (Ray, 2015). These communication gadgets are able to transmit signals both in digital and in an analog format. The emergence of these technologies has improved the efficiency as well as the speed with which users communicate using wireless devices.There are various wireless technologies that are currently available in the digital world. One of the major examples of wireless technologies is the Wi-Fi (IEEE 802.11) technology. This technology s based on a radio frequency that uses routers to connect one or more computer hardware (Ray, 2015). This technology has been designed to operate on three major protocols with a different set of frequencies. The other common example of wireless technologies is the ZigBee (802.15.4) technology. ZigBee technology has security features in the form of 128-bit AES encryption. Additionally, this technology uses a mesh topology to allow connection through multiple pathways. This technology has wider application areas, including home-based IoT devices. The other common technology is the WiMAX (IEEE 802.16). This technology is designed to allow data transfer between devices at a speed that ranges from 30-40 MBps. This technology is sometimes used by mobile service carriers to deliver wireless data to their customers.There are various security protocols that can be applied to secure 802.11. Examples of such security strategies are the WEP, WPA, and WPA2. All these securities come from the same protocols but have been improved over time to offer better security features (Arefin et al.,
