What is the Purpose of Drive Test?

Quality control inspectors examine products and materials for defects or deviations from specifications.

Duties

Quality control inspectors typically do the following:

• Read blueprints and specifications
• Monitor operations to ensure that they meet production standards
• Recommend adjustments to the assembly or production process
• Inspect, test, or measure materials or products being produced
• Measure products with rulers, calipers, gauges, or micrometers
• Accept or reject finished items
• Remove all products and materials that fail to meet specifications
• Discuss inspection results with those responsible for products
• Report inspection and test data
• RF Drive Tester

Quality control inspectors, for example, ensure that the food or medicine you take will not make you sick, that your car will run properly, and that your pants will not split the first time you wear them. These workers monitor quality standards for nearly all manufactured products, including foods, textiles, clothing, glassware, motor vehicles, electronic components, computers, and structural steel. Specific job duties vary across the wide range of industries in which these inspectors work.

Quality control workers rely on many tools to do their jobs. Although some still use hand-held measurement devices, such as calipers and alignment gauges, workers more commonly operate electronic inspection equipment, such as coordinate-measuring machines (CMMs). Inspectors testing electrical devices may use voltmeters, ammeters, and ohmmeters to test potential difference, current flow, and resistance, respectively.

Quality control workers record the results of their inspections through test reports. When they find defects, inspectors notify supervisors and help to analyze and correct production problems.

In some firms, the inspection process is completely automated, with advanced vision inspection systems installed at one or several points in the production process. Inspectors in these firms monitor the equipment, review output, and conduct random product checks.

The following are examples of types of quality control inspectors:

Inspectors mark, tag, or note problems. They may reject defective items outright, send them for repair, or fix minor problems themselves. If the product is acceptable, the inspector certifies it. Inspectors may further specialize in the following jobs:

• Materials inspectors check products by sight, sound, or feel to locate imperfections such as cuts, scratches, missing pieces, or crooked seams.
• Mechanical inspectors generally verify that parts fit, move correctly, and are properly lubricated. They may check the pressure of gases and the level of liquids, test the flow of electricity, and conduct test runs to ensure that machines run properly.

Samplers test or inspect a sample for malfunctions or defects during a batch or production run.

Sorters separate goods according to length, size, fabric type, or color.

Testers repeatedly test existing products or prototypes under real-world conditions. Through these tests, manufacturers determine how long a product will last, what parts will break down first, and how to improve durability.

Weighers weigh quantities of materials for use in production.

What is the future of being an RF engineer?

RF Technician Jobs :
RF engineers have some scope in telecom vendors like Nokia Networks, Ericsson, Huawei, ZTE, Alcatel- Lucent and Idea Cellular (Idea manage its own networks rest outsource). Even these companies hire only few engineers for RF planning work and outsources field work (RF testing in the field) to small vendors. Also RF engineers job is low paid job when you start as a drive test engineer which involved your 24/7 hrs of work efforts and its become even more challenging because RF engineers workload increase more in extreme whether condition. Even after working for many years as a RF engineers there is very few scope for your career growth as this works doesn't add any value in you.

Radio-frequency (RF) engineering is not the type of career that has a high attrition rate. But if the profession is as good as it sounds, why are companies having such a difficult time finding RF engineers to fill their vacant positions?

There are two main reasons. The first is due to the basic supply and demand rule. The wireless communications field has grown steadily in recent years, much like the software and computer engineering fields.

Because the demand for software engineers has been so great, and the profession has a reputation of paying extremely high salaries, many engineering students have focused on this field.

"Most students in electrical engineering have been attracted by computer engineering," says Edward Jull. He's an electrical engineering professor.

"The present demand for radio-frequency engineers is also a result of the growth of wireless communications and the development of integrated circuits and computers."

The other reason there seems to be a shortage of RF engineers is that courses in RF are often hard to find in many universities.

"It's quite difficult to find a direct path to RF," says Lorna Carr. She is a senior RF engineer.

She says that when she was attending university, there were extremely few courses available in RF. Upon graduation, she says she was offered a position with a company where she was exposed to the skills required by an RF engineer.

She then took it upon herself to learn the rest of the skills needed to get involved with the RF side of engineering. "I was pretty much self-taught," admits Carr. "I would read for an hour to an hour and a half each morning before work."

What is a Noc Technology?

NoC technology is often called “a front-end solution to a back-end problem.” As semiconductor transistor dimensions shrink and increasing amounts of IP block functions are added to a chip, the physical infrastructure that carries data on the chip and guarantees quality of service begins to crumble. Many of today's systems-on-chip are too complex to utilize a traditional hierarchal bus or crossbar interconnect approach. Yesterday's village traffic has turned into today's congested freeways.

Arteris network-on-chip technology is characterized by these technological features:

1. Separation of transaction, transport and physical layers
2. Packetization of data, which enables variable bit-widths through flexible serialization
3. Support for any transaction prototocol, whether ARM AMBA, OCP, or proprietary

Network Operation Center Definition

What is Network Operations? & Best Practices

Network Operations refers to the activities performed by internal networking staff or third parties that companies and service providers rely on to monitor, manage, and respond to alerts on their network's availability and performance. Staff that have primary responsibilities for network operations are often called network operations analysts or network operations engineers.

A Network Operations Center, often called a NOC (pronounced "knock"), is typically a centralized location where the network operation staff provides 24x7x365 supervision, monitoring, and management of the network, servers, databases, firewalls, devices and related external services. This infrastructure environment may be located on-premises and/or with a cloud-based provider.

Some key Network Operation activities are:

• Network monitoring
• Incident response
• Communications management (Email, voice, & video)
• Performance, quality, and optimization reporting
• Software/firmware installation, troubleshooting and updating of network elements
• Patch management
• Backup and storage
• Firewall management
• Intrusion Prevention System (IPS) and other security tool deployment and monitoring, in collaboration with Security Operations
• Threat analysis and blast radius analysis in collaboration with Security Operations

Challenges Facing Network Operations

Because of the complexities involved with today's networks and services, especially in light of the adoption of cloud-based infrastructure and SaaS applications, there are many challenges that network operations staff face not only associated with having a thorough understanding of the technology itself, but in maintaining streamlined communications access between all those involved.

Some key network operation challenges include:

• Lack of collaboration/coordination across teams
• Fast pace of change in the cloud and dynamic resource orchestration means that documentation is usually not up-to-date for troubleshooting problems
• Troubleshooting is time consuming because it often involves correlating data across multiple devices and tool sets and requires manual processes to arrive at sound diagnoses
• Many disparate tools from different vendors in use that may require staff work with different technologies, low-level utilities and Command Line Interfaces (CLI)
• Problems arise and then disappear by the time all information is collected that is necessary for troubleshooting
• Escalation to more senior staff is required frequently to assess root causes

Network Operations Best Practices

Well run network operations teams embrace a variety of tried-and-true best practices. These include but are not limited to the following:

• Continuously monitoring a wide variety of information and network systems that include communications circuits, cloud resources, LAN/WAN systems, routers, switches, firewalls and VoIP systems and application delivery.
• Providing timely response to all incidents, outages and performance issues.
• Categorizing issues for escalation to appropriate technical teams.
• Recognizing, identifying and prioritizing incidents in accordance with customer business requirements, organizational policies and operational impact.
• Collecting and reviewing performance reports for various systems, and reporting trends in performance to senior technical personnel to help them predict future issues or outages.
• Documenting all actions in accordance with standard company policies and procedures.
• Notifying customer and third-party service providers of issues, outages and remediation status.
• Working with internal and external technical and service teams to create and/or update knowledge base articles.
• Performing basic systems testing and operational tasks (installation of patches, network connectivity testing, script execution, etc.).
• Supporting multiple technical teams in 24x7 operational environments with high uptime requirements. Varied shift schedules may include day or evening hours.

What Does Noc Mean

A network operations center (NOC) is a central location from which network administrators manage, control and monitor one or more networks. The overall function is to maintain optimal network operations across a variety of platforms, mediums and communications channels.

Large network service providers are associated with network operation centers, which feature a visual representation of the networks being monitored and workstations where detailed network statuses are monitored. Software is employed to help manage the networks. Telecommunications, television broadcast and computer networks are controlled through network operations centers.

Network operations centers are also known as network management centers.

A network operation center monitors the telecommunication network for alarms or certain conditions that may require special attention in order to avoid impact on network performance. They monitor power failures, communication line alarms and performance issues that may affect networks. NOCs are capable of analyzing problems, performing troubleshooting, communicating with site technicians and tracking problems until they are resolved. Network operation centers serve as the main focal point for software troubleshooting, software distribution, and updating router and domain name management in coordination with affiliated networks and performance monitoring.
