LMDS/MMDS

This course is designed for technical individuals and anyone needing a solid foundation for understanding the principles of LMDS. Prerequisites: Good knowledge of Microwave technologies is recommended. Course Description: Local Multipoint Distribution Services (LMDS) is a fixed broadband wireless access system using a range of frequencies around 28-31 GHz. This service allow......
 

RF is RF,�is an expression often heard from RF engineers. However, the understanding of RF propagation is far from intuitive, and the lack of this understanding can adversely affect the system performance. How does the RF energy propagate through space? How is it impacted by the presence of buildings, mountains, lakes, vegetation, and other natural and man-made structures? How does one “budget......
 

The family of standards referred to as cdma2000 is one of the two major technology options for third generation (3G) wireless. It’s an evolving technology, with 1xRTT being the first and, in some ways, the most pivotal member of this family. While building on the very successful cdmaOne or IS95 technology, it adds a number of capabilities along with the engineering issues that go with them. ......
 

Communications networks are rapidly evolving into policy-based, packet-oriented networks designed to provide a particular quality-of-services (QoS) for subscribers while reducing the costs associated with capital expansions, network operations, and management. If you are involved with telecommunications engineering, deployment, strategy, marketing, or services creation, it is critical that you ......
 

While less widely deployed than other technologies, iDEN�was the first to bring “push-to-talk�to a sizeable market. Unlike other technologies, iDEN�is a proprietary technology developed by Motorola. Some aspects of iDEN�, being proprietary, can create difficulties for those working with this technology. However, since it’s a TDMA-based technology, many of the issues are already widely under......
 

High Speed Uplink Packet Access (HSUPA), a technology that complements High Speed Downlink Packet Access (HSDPA), is an evolutionary step that makes the uplink of WCDMA packet-based for data services. Together, HSDPA and HSUPA offer reduced latency and much higher data rates on the downlink and uplink, theoretically as high as 14.0 Mbps in the downlink and up to 5.8 Mbps in the uplink. They are......
 

HSDPA, short for High-Speed Downlink Packet Access, is a new protocol for mobile telephone data transmission. It is known as a 3.5G (G stands for generation) technology. Essentially, the standard will provide download speeds on a mobile phone equivalent to an ADSL (Asymmetric Digital Subscriber Line) line in a home, removing any limitations placed on the use of your phone by a slow connection. ......

A technology that gives GSM the capacity to handle services for the third generation of mobile telephony. EDGE provides three times the data capacity of GPRS. Using EDGE, operators can handle three times more subscribers than GPRS, triple their data rate per subscriber, or add extra capacity to their voice communications. EDGE uses the same TDMA (Time Division Multiple Access) frame structure, ......
 

Since all future technologies, 3G and beyond, will likely employ some form of CDMA, understanding CDMA is imperative for all wireless industry professionals. Imparting such understanding is the objective of this course. Taught are the general principles that underlie all CDMA systems, strengths and limitations of CDMA, and its implementation in the 3G systems now in development around the world......
 

This course is designed to provide a general overview for strategic or technical managers, consultants, communications professionals, software engineers, system engineers, network professionals, marketing and sales professional, IT professionals, and others who plan on using, evaluating or working with TDMA wireless networks, applications and services. Prerequisites: A basic underst......
 

Bluetooth is the name of a wireless technology standard for connecting devices, set to replace cables. It uses radio frequencies in the 2.45 GHz range to transmit information over short distances of generally 33 feet (10 meters) or less. By embedding a Bluetooth chip and receiver into products, cables that would normally carry the signal can be eliminated. While entertainment centers, comput......
 

This three-day course teaches the basics of antenna and antenna array theory. Fundamental concepts such as beam patterns, radiation resistance, polarization, gain/directivity, aperture size, reciprocity, and matching techniques are presented. Different types of antennas such as dipole, loop, patch, horn, dish, and helical antennas are discussed and compared and contrasted from a performance/app......
 

This course seeks to provides insight into the development 3G LTE and 4G, the next generation of mobile networks. 3G LTE, which stands for 3G Long Term Evolution, is being standardized by 3GPP and 3GPP2 and is often described as �.9G� It is a technology that will enable cellular networks to support up to 10 times higher data rate and more users than existing HSxPA networks. It will employ......
 

An advanced class covering the Wireless LAN standards that are most relevant to your next design project. This course will provide the student with broad knowledge on current Wireless LAN (WLAN) standards, trends, issues and technologies. We have included content that is emerging from recent IEEE 802.11 WLAN working group meeting and letter ballots. These are the critical topics for today s dev......
 

Anyone who is interested in understanding synchronization and timing in telecom network, including technicians, engineers, operators, and sync managers. Prerequisites: Course (Synchronization Fundamentals) or equivalent knowledge is recommended. Course Description: Timing and synchronization are critical in the telecom networks such as PSTN, SONET/SDH, DWDM, ATM, and VoI......
 

SNMP is a widely used protocol that facilitates the management of networked devices from a central location. Originally intended only for the management of network devices such as routers and switches, its usage has grown rapidly to encompass the monitoring of nearly any electronic device one can think of. SNMP is now used to monitor and manage television broadcast studios, automated fare colle......
 

A VPN is a communications environment in which access is controlled to permit peer connections only within a defined community of interest, and is constructed though some form of partitioning of a common underlying communications medium, where this underlying communications medium provides services to the network on a non-exclusive basis. Virtual private networks have become an essential par......
 

Microwave links - fixed line-of-sight in particular �present some unique problems in areas such as propagation and fading characteristics. Mobility not being an issue, the relationship of the wave-length to the lengths of man made or natural obstacles becomes the principal concern in such environments. This course will help you understand the (often non-intuitive) effects various obstacles ......
 

Carriers today are excited about the opportunities to further their positioning along the value chain of differentiated service offerings, including mobile television. Technologies like DVB-H, DVB-SH MediaFlow, and T-DBM and now, TDtv, can be challenging to understand as each vies for global standard dominance. Audience: RF Engineers, data planners, network planners and designers, t......
