Analog-to-digital conversion is an electronic process in which a continuously variable (analog) signal is changed, without altering its essential content, into a multi-level (digital) signal.
The input to an analog-to-digital converter (ADC) consists of a voltage that varies among a theoretically infinite number of values. Examples are sine waves, the waveforms representing human speech, and the signals from a conventional television camera. The output of the ADC, in contrast, has defined levels or states. The number of states is almost always a power of two -- that is, 2, 4, 8, 16, etc. The simplest digital signals have only two states, and are called binary. All whole numbers can be represented in binary form as strings of ones and zeros.

Analysis of wifi and wimax and wireless network coexistenceIJCNCJournal
Wireless networks are very popular nowadays. Wireless Local Area Network (WLAN) that uses the IEEE 802.11 standard and WiMAX (Worldwide Interoperability for Microwave Access) that uses the IEEE802.16 standard are networks that we want to explore. WiMAX has been developed over 10 years, but it is still unknown by most people. However, compared with WLAN, it has many advantages in transmission speed and coverage area. This paper will introduce these two technologies and make comparisons between WiMAX and WiFi. In addition, wireless network coexistence of WLAN and WiMAX will be explored through simulation. Lastly we want to discuss the future of WiMAX in relation to WiFi.

Verilog Based Design and Simulation of MAC and PHY Layers for Zigbee Digital ...IJERA Editor
The past several years have witnessed a rapid development in the wireless network area. So far wireless networking has been focused on high-speed and long range applications. Zigbee technology was developed for a Wireless Personal Area Networks (WPAN), aimed at control and military applications with low data rate and low power consumption. Zigbee is a standard defines the set of communication protocols for low-data-rate short-range wireless networking. Zigbee-based wireless devices operate in 868 MHz, 915 MHz, and 2.4 GHz frequency bands. The maximum data rate is 250K bits per second. Zigbee is mainly for battery-powered applications where low data rate, low cost, and long battery life are main requirements. This paper explores Verilog design for various blocks in Zigbee Transmitter architecture for an acknowledgement frame. The word digital has made a dramatic impact on our society. Developments of digital solutions have been possible due to good digital system design and modeling techniques. Further developments have been made and introduced VLSI in order to reduce size of the architecture, to improve speed of operation, improvements in predictability of the circuit behavior. Digital Zigbee Transmitter comprises of Cyclic Redundancy Check, Bit-to-Symbol block, Symbol-to-chip block, Modulator and Pulse shaping block. The work here is to show how we can design Zigbee transmitter with its specifications by using Verilog with less number of slices and Look up tables (LUTs).
EMERGING BROADBAND WIRELESS TECHNOLOGIES: WIFI AND WIMAXcscpconf
Now-a-days there is high demand for broadband mobile services. Traditional high-speed
broadband solutions depend on wired technologies namely digital subscriber line (DSL). Wifi
and Wimax are useful in providing any type of connectivity such as the fixed or portable or
nomadic connectivity without the requirement of LoS (Line of Sight) of the base station. Mobile
Broadband Wireless Network (MBWN) is a flexible and economical solution for remote areas
where wired technology and also terminal mobility cannot be provided. The IEEE Wi-Fi and
Wi-Max/802.16 are the most promising technologies for broadband wireless metropolitan area networks (WMANs) and these are capable of providing high throughput even on long distances with varied QoS. These technologies ensure a wireless network that enables high speed Internet access to residential, small and medium business customers, as well as Internet access for WiFi hot spots and cellular base stations. These offer support to both point-to-multipoint (P2MP) and multipoint-to-multipoint (mesh) nodes and offers high speed data (voice, video) service to the customers. In this paper, we study the issues related to, benefits and deployment of these technologies.

Wireless Data Communication Techniques to Coordinate Distributed Rooftop PVs ...TELKOMNIKA JOURNAL
A necessity of the availability of communication network to provide data transfer amongst the
coordinated single-phase rooftop photovoltaic (PV) in unbalanced three-phase low voltage (LV) feeder is
essential since fetching data within the sensor of each PV unit requires real-time measurement and
reliable data exchange within smart grid (SG), loads and other PV units. The main objective of this paper is
to model the popular Wi-Fi, WiMax and ZigBee wireless data communication techniques into algorithms
using numerical analysis. Those communication technologies have low cost and low power consumption.
The benefits and drawbacks of those considered wireless data communications are shown as the required
data that transferred and appropriate coding is also proposed. The number of transmitted symbols and the
processing time delay of the proposed data coding are numerically analyzed, the results indicated that the
100% penetration level of PV that resulted higher injected reactive power back into the networks is able to
be overcome since the coordinated PVs along the feeder is communicating to lower the unbalanced
voltage profile.
COMPARATIVE PERFORMANCE ANALYSIS OF THE IEEE802.11AX AND 802.11AC MIMOLINK FO...pijans
The escalating demand for swift and dependable wireless internet access has spurred the development of
various protocols within 802.11 WLANs. Among them, the 802.11ac protocols have gained widespread
acceptance over the past few years, offering enhanced data transfer rates compared to the 802.11n
standard. However, the persistent congestion of wireless IoT devices, particularly in densely populated
areas, remains a significant challenge. To tackle this issue, IEEE 802.11 has advanced IEEE 802.11ax as
the successor to 802.11ac, introducing critical enhancements at the PHY/MAC layers to improve
throughput in dense scenarios. Additionally, modelling and simulating these protocols are vital for WLAN
researchers and designers to anticipate link characteristics effectively, fostering high-performance WLAN
design. The need for such tools led to the creation of diverse network simulation programs, and NS-2 is
widely accepted as an open-source program that has achieved remarkable success in research. In this
paper, we focus on various connection properties of 802.11ax WLANs through NS-3 simulations, including
MCSs, bonded channels, GI, data encoding, antennas, data rates, link distance, Tx/Rx power, gain, and
payload size. We also compare their performance against 802.11ac, which demonstrates that NS-3
accurately supports most 802.11ax capabilities and outperforms 802.11ac in various scenarios.
The universe of remote broadcast communications is quickly developing. Advances under research and development guarantee to convey more administrations to more clients in less time. This paper exhibits the rising innovations helping wireless systems develop from where we are today into our dreams of the future. WiMAX (Worldwide Interoperability for Microwave Access) is a standard for wireless transmission covering a reach like mobile phone towers. With superior in both range and throughput, WiMAX innovation could be a help to current Internet suppliers trying to wind up the pioneer of cutting edge remote Internet access. This paper likewise investigates how these developing advances vary from each other.
