IT technicians are required by most companies, as they offer support for computer systems. Being versatile, as they secure IT systems, troubleshoot problems and provide network support and so on, future looks promising for them.

If they upgrade themselves by obtaining certifications, they can climb up the value chain to become managers or senior IT personnel. Besides, they can be employed in various organizations, both in the public and private sectors, as they have a broad range of responsibilities.

According to the BLS (US Bureau of Labor Statistics), there is expected to be a growth of 11% in employment opportunities between 2016 and 2016. With upgrades to computers, IT Technicians can look forward to the creation of more jobs.

Moreover, many small and medium and, sometimes, even large companies are outsourcing IT technical support because they can reduce costs by turning to technicians only when issues arise. Also, outsourcing companies work round-the-clock, allowing businesses to contact them whenever they encounter problems. Finally, it will enable enterprises to focus on their core business processes, as they need not worry about resolving the technical problems of their systems.

Wireless site survey specialists jobs

Wireless Site Surveys are conducted using devices and software that collect and analyses WLAN metrics and RF spectrum properties. Valid range is set defining the area in which wireless connectivity is required. During the survey, a surveyor walks the facility with a portable computer that continuously records data. Each location surveyed is marked manually or through GPS, and these statistics are collected:

Signal Strength run.
Noise (electrical, not audio)
Signal to Noise Ratio (SNR) – (This determines the minimum signal needed
for given applications to run effectively)
Bandwidth

After these parameters are collected, they are analyzed with specialized software.

Types of Wireless Site Surveys:

There are three types of site survey in which a specialist performs:

Passive:In this type of survey, WLAN traffic is monitored to detect possible access points and measure the signal strength and noise level.

Active:During the active survey wireless adapters are associated with multiple access points. The active survey checks the performance post-deployment the wireless network. If any error is found for data transfer, then it can be fixed.

Predictive:In this type of survey, the RF modeling is created using mockup tools. Virtual access points are placed on the given area of the network to estimate the expected coverage.

When somebody asks me a question “what kind of work do you do?" I answer, a "SIM-card software developer”, even well versed in software development people are often surprised. Many people think that the SIM-card is something like a flash drive.

In this article I will briefly tell you about the SIM-card (and smart cards in general), what for it is needed and what it has inside.

In fact, the SIM-card is an instance of a contact smart card with a microprocessor. It represents a fairly secure microcomputer with CPU, ROM (optional), RAM and NVRAM (which stands as a prototype of the hard drive in the PC) with hardware generators of random numbers and hardware implementation of cryptographic algorithms.

The structure of microprocessor smart card can be as:
