Fundamental of WiMAX
What is WiMAX?
WiMAX (Worldwide Interoperability for Microwave Access) is a wireless communications standard designed to provide 30 to 40 megabit-per-second data rates, with the 2011 update providing up to 1 Gbit/s for fixed stations.
With the further development of the communication network, WiMAX has major realistic significance and strategic value as a standard facing to “the last kilometer” access, especially when no globally uniform standard is established for broadband wireless access. There are two main types of such standard: the IEEE 802.16d supporting air interface of fixed broadband wireless access system, and the IEEE
802.16e in the works supporting the air interface of both fixed and mobile broadband wireless access systems.WiMAX is a Broadband Wireless Access Metropolitan Area
Network (BWA-MAN) technology based on the IEEE 802.16 standard, which is also called the IEEE Wireless MAN. It is a new air interface standard in connection with the frequency ranges of microwave and millimeter wave. Its main purpose is to provide a broadband wireless access approach which can be interoperated effectively in the environment of multiple manufacturers with "one-point to multi-point" in the metropolitan area network. [1]

2.1 Types of WiMAX
The WiMAX family of standards addresses two types of usage models: a fixed-usage model (IEEE 802.16-2004) and a portable usage model (802.16 REV E, scheduled for ratification in current year). The basic feature that differentiates these systems is the ground speed at which the systems are designed to operate. Based on mobility, wireless access can be divided into four classes: stationary (0 km/hr), pedestrian (up to 10 km/hr), and vehicular (sub classified as “typical” up to 100 km/hr and “high speed” up to 500 km/hr).

A mobile wireless access system is one that…...

...Fundamentals Macroeconomics is the study of the economy as a whole as opposed to microeconomics, which is the study of the economy within smaller sectors. It is a wide and varying subject. In order to grasp the subject there are some fundamentals that one needs to be familiar with. They are the gross domestic product (GDP), real gross domestic product (GDP), nominal gross domestic product (GDP), unemployment rate, inflation rate, and interest rate. These are the basics and interact with each other to determine the condition of the economy at any given moment. Domestic Products The gross domestic product is the total of everything produced within the US economy during a given period of time. It is the market value of all FINAL products. This means that only when an item is ready for consumer purchase is it tallied into the GDP. The individual pieces of the product are not counted before production. The GDP is used to get the real gross domestic product (GDP) and the nominal gross domestic product (GDP). The real GDP is what the GDP itself is actually worth as opposed to what it cost. The nominal GDP is the face value of the GDP. In other words, what it is actually going to sell for. Rates The unemployment rate is the number of people who are able, available to work, and actively seeking employment but who are not actually working. Inflation rate is the rate prices rise in a given period and interest rate is a percent of what one is charged when he or she charges an item....

...2 1.2 objectives of the study 2 1.3 Operational Definition 3 1.4 Literature review 4 2.1 Methodology of Data Collection 24 3.1 Conclusion 24 3.2 Reference 25 1.1 Introduction WiMAX is a wireless digital communications system, also known as IEEE 802.16, that is intended for wireless "metropolitan area networks". WiMAX can provide broadband wireless access (BWA) up to 30 miles (50 km) for fixed stations, and 3 - 10 miles (5 - 15 km) for mobile stations. In contrast, the WiFi/802.11 wireless local area network standard is limited in most cases to only 100 - 300 feet (30 - 100m). With WiMAX, WiFi-like data rates are easily supported, but the issue of interference is lessened. WiMAX operates on both licensed and non-licensed frequencies, providing a regulated environment and viable economic model for wireless carriers. WiMAX can be used for wireless networking in much the same way as the more common WiFi protocol. WiMAX is a second-generation protocol that allows for more efficient bandwidth use, interference avoidance, and is intended to allow higher data rates over longer distances. 1.2 objectives of the study ➢ To know details about the WiMax technology.   1.3 Operational Definition WiMAX- WiMAX (Worldwide Interoperability for Microwave Access) is a wireless industry coalition dedicated to the advancement of IEEE 802.16 standards for broadband wireless access (BWA) networks.

Fundamental Rights

...A brief note on Fundamental Rights given to a citizen in Constitution of India. The Fundamental Rights embodied in the Indian constitution act as a guarantee that all Indian citizens can and will lead their lives in peace as long as they live in Indian democracy. These civil liberties take precedence over any other law of the land. They include individual rights common to most liberal democracies, such as equality before the law, freedom of speech and expression, freedom of association and peaceful assembly, freedom of religion, and the right to constitutional remedies for the protection of civil rights such as habeas corpus. In addition, the Fundamental Rights for Indians are aimed at overturning the inequities of past social practices. They have also been used to in successfully abolishing the "untouchability"; prohibit discrimination on the grounds of religion, race, caste, sex, or place of birth; and forbid trafficking in human beings and also the forced labor. They go beyond conventional civil liberties in protecting cultural and educational rights of minorities by ensuring that minorities may preserve their distinctive languages and establish and administer their own education institutions. FUNDAMENTAL RIGHTS Originally, the right to property was also included in the Fundamental Rights; however, the Forty-fourth Amendment, passed in 1978, revised the status of property rights by stating that "No person shall be deprived of his property save by authority of law."...

Ollo Wimax Internet Service Provider

...Ollo. Brand image includes products' appeal, ease of use, functionality, fame, and overall value. Ollo’s competitor Banglalion and qubee holds positive brand image as leading wimax provider in Bangladesh exceeding the customer expectations. Ollo’s marketing plan was to develop a brand experience that would differentiate the new product within the saturated telecoms market. But due to poor communications people are not aware of Ollo. It has problem in reaching its target audiences. From the beginning till now Ollo is unable to create relationship with its customer. As a result Ollo hardly moved from brand parity level and is still quite far from reaching brand equity. Ollo’s present sales is not enough to make revenue and increase market share. It needs integrated marketing communications to establish itself as a new telecom brand providing high-speed internet access to emerging markets. 4. Market Research Research Objective The primary objective of this research is to know what people actually think about Ollo Bangladesh. We wanted to know if people consider Ollo as their top choice or not. If not then what are the reasons behind it. The goal of research is also to know why Ollo is not able to create brand equity and brand image, why people prefer other operators over Ollo, what people find in other WiMAX provider that are missing in Ollo that lead them not to use their service. This research will help to find out the reasons why it is still not able to move from brand......

...Assignment 1: Fundamentals of Effective Communication in the Workplace Professor BUS 100 – Introduction to Business May 13, 2014 I work for a defense attorney, and I experience effective communication on a daily basis via email with co-workers and clients. However, I do feel that face-to-face communication is highly effective and important. With face-to-face meeting, the co-workers and clients directly receive the message, and feedback is instantly provided. Resolutions can be made easier during a face-to-face meeting rather than via email or phone conversations. About six months ago I was part of a financial turn around that was a result of successful face-to-face communication. The firm’s office that I work for is called McCallum Law Offices, and my position in the department is senior paralegal and office manager. We work closely with the justice department and handling the financial and critical situations of our client’s lives. A main part of my job was to reconcile financial reports, and have the senior attorney approve them, and then submit them for reimbursement. We were having major issues with the financials and how they accounts were being handled. As with most offices now communication is usually handled via e-mail. When you start having issues like we were, there is only one way to handle this and that is for everyone to be face to face. So if there are any issues they can be resolved immediately. Attorney offices can become very......

Fundamentals of Microeconomics

...RUNNING HEAD: FUNDAMENTALS OF MACROECONOMICS 1 Fundamentals of Macroeconomics ECO/372 February 5, 2015 Samuel Imarhiagbe FUNDAMENTALS 2 Fundamentals of Macroeconomics Macroeconomics studies an economy at the aggregate level. It is concerned with the workings of the whole economy or large sectors of it. These sectors include government, business, and households. Macroeconomics deals with such issues as national economic output and growth, unemployment, recession, inflation, foreign trade, and monetary and fiscal policy (Koch, 2015). Macroeconomics is utilized when looking at the impact that activities such as purchasing groceries, massive employee layoffs and a decrease in taxes have on the government, households and businesses. Purchasing Groceries Grocery shopping is an activity that almost every household is expected to participate in. Approximately 15% of American income is spent on groceries; the smallest rise in prices can impact a family’s budget (Parker, 2011). Food prices are determined by several factors including, but not limited to, the economy, taxes, regulations and demand. If the demand for certain products is down or the economy is not doing well, the government may increase taxes on items, including groceries. If the price of groceries increases, consumers may be obligated to purchase a lesser amount of groceries or may begin purchasing a FUNDAMENTALS 3 lower quality of groceries from......

...Macroeconomics Fundamentals of Macroeconomics Paper Lisa Goodman ECO/372 8/20/2015 Laurie Klosk-Gazzale Fundamentals of Macroeconomics Paper Massive layoff of employees is huge problem skyrocketing the unemployment rate because companies are globalization which increase their profits and save the consumer money by giving jobs international instead of locally where minimum wage is higher. Calabresi (2015) “In an unhealthy economy, a single lost job becomes infectious, combining with others and spreading through family, neighborhood and community. Widespread cutbacks in spending by families mean lower demand for businesses and lower tax revenues for the government. This belt-tightening means fewer car sales and thus fewer jobs for car-part makers. It means less government spending on infrastructure and other public services, including economic development” (para, five). Decrease in taxes can be seen if we measure the nation’s wealth. We would look at the GNP (Gross national product. This look at how taxes affect output. We then would look at the aggregate demand equation. * C = consumption spending by individuals * I = investment spending (business spending on machinery, etc.), * G = government purchases * NX = net exports Cloutier (2015), “Consumer spending typically equals two-thirds of GNP. As you would expect, lowering taxes raises disposable income, allowing the consumer to spend additional sums, thereby, increasing GNP. Reducing taxes,......
