Scope Of RFID Systems In Security Measures

On July 31, 2017, in Antenna, Electrode Products, by Lambert

What is RFID?

 

Radio-frequency identification device is a technology that retrieves the status and presence of a thing to which it is attached to remotely. These devices will track the objects automatically and sends the embedded information to the processors.

 

Typical components of RFID system

 

An RFID system contains an RFID tag, RFID reader, RFID antenna, and RFID package.

 

RFID tag is attached to the item that needs to be tracked and identified.

 

RFID antenna will detect the RFID tag when it comes in range.

 

RFID reader reads the RFID tags and authenticates its presence.

 

RFID package contains the server and software and transmits the information to all other applications.

 

Application of RFID systems

 

To simplify, RFID systems do the same function as of a BAR-CODES, but when it comes to applications they are widely spread as RFID systems doesn’t need to maintain contact with the scanners as in case of BAR-CODE. High Frequency RFID systems doesn’t necessarily to be appear in the line of sight, especially such are applied for livestock tracking, Missile tracking, automobile tracking through assembly lines and most importantly in case of vehicle tracking.

 

Security potential

 

Increasing security measures through CCTV cameras has already outdated, the latest technology implies to the usage of RFID readers wherever the security is needed along with authentication.

 

They can be installed in a library, home, and elsewhere domestically to secure the important files, books, and expensive things, so that even when they are found missing they can be easily detected with the help of local servers that are giving location information.

 

They can also be placed in a vehicle, thanks to their non-contact readable characteristic feature as the vehicles can be tracked along the route as they can use the location provided by the nearest GSM signal boosting towers and thus one can keep notice of their vehicles.

 

The size of the smallest developed RFID is 0.05mm × 0.05mm size and the average size would be around 3mm x 3mm. As we go cheaper the size will be increased consistently. Their dimensions make them invisible to see which a plus point in terms of security measures is.

Selecting for Right 4G LTE Antennas

On June 23, 2017, in Antenna, Telecommunication, by Lambert

Choosing the right gateway or router isn’t all there is to successful mobile networking. Signal quality is essential and this can only be guaranteed by picking the right 3G or 4G LTE antenna and solutions.

 

Selecting the right antenna

When selecting an antenna the following considerations need to be made:

 

Where will the antenna need to be situated?

If outside then the antenna will need the appropriate IP rating to ensure it is protected against dust and water. If inside then it will need to be of a suitable size.

 

What application is the antenna being used for?

Different applications require different types of antennas, for example WiFi and GPS will require their own antennas in addition to cellular antennas.

 

What environment is the antenna being placed in?

For example, vehicular or industrial locations will require an antenna that is suitably ruggedized with the appropriate fixtures.

 

What is the quality of the signal in the intended location?

If the signal quality is poor then a high gain external antenna may suit it best.

 

What frequency band are you using?

Most high quality antennas cover a wide range of frequencies, but some cheaper antennas are only suitable for one type of connectivity, e.g. 2G, 3G or 4G.

 

How visible will the antenna be?

If it is highly visible in a prominent location then it may be important that it is aesthetically suitable.

 

Where and how does the antenna need to be fixed?

Different locations require for the antenna to be attached in different places, for example on a window, wall or ceiling, and will therefore require different types of fixtures, for example screw-on, stick-on or magnetic.

 

After these questions have been addressed, the process of selecting the correct 4G LTE antenna can begin.

 

Established in 1993, Evercom Communication specializes in manufacturing 4G LTE antennas. The new next generation of in-vehicle connectivity through 4G LTE solution can be monitored and managed remotely from the cloud.
