The document discusses WiMAX technology and architecture. It provides an overview of the IEEE 802.16 standard, operating frequencies, data rates, network components, and services supported. The key components of a WiMAX network include the subscriber stations, access service network with base stations, connectivity service network with AAA and DHCP servers, and network service provider layer which offers various applications and services to subscribers.
WIMAX stands for Worldwide Interoperability for Microwave Access.WiMAX refers to broadband wireless networks that are based on the IEEE 802.16 standard, which ensures compatibility and interoperability between broadband wireless access equipment.
Universal mobile telecommunication System (UMTS) is actually the third generation mobile, which uses WCDMA. The Dream was that 2G and 2.5G systems are incompatible around the world.
-Worldwide devices need to have multiple technologies inside of them, i.e. tri-band phones, dual-mode phones
To develop a single standard that would be accepted around the world.
-One device should be able to work anywhere.
Increased data rate.
- Maximum 2048Kbps
UMTS is developed by 3GPP (3 Generation Partnership Project) a joint venture of several organization
3G UMTS is a third-generation (3G): broadband, packet-based transmission of text, digitized voice, video, multimedia at data rates up to 2 Mbps
Also referred to as wideband code division multiple access(WCDMA)
Allows many more applications to be introduce to a worldwide
Also provide new services like alternative billing methods or calling plans.
The higher bandwidth also enables video conferencing or IPTV.
Once UMTS is fully available, computer and phone users can be constantly attached to the Internet wherever they travel and, as they roam, will have the same set of capabilities.

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.
IEEE 802 Standard Network’s Comparison under Grid and Random Node Arrangement...Eswar Publications
The IEEE 802 standard well-known as 802.11 called as Wi-Fi network, 802.15.4 called as ZigBee or sensor network and 802.15.1 called as Bluetooth network. The network such as ZigBee, Bluetooth and Wi-Fi works in 2.4 GHz ISM band. All the above networks works in same ISM band of 2.4 GHz, but the performance of the network varies. The performance of simulation depends upon the coverage area, data rates, and power consumption in each network. The heterogeneous network performances is evaluated with static and mobility model in random and grid node placement by varying the traffic loads of one CBR and with five CBR for each network. The
simulation result is compared in terms of jitter, average end to end delay and throughput to analyze the network performance in the 2.4 GHz frequency band. IEEE 802.11 network shows the low jitter and delay value with high throughput compared with sensor network.
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).
