FAQ
Â
Why should we use special collectors in refrigerated storage area?
Just as workers need to adjust their equipment to work in an area of cold storage, mobile computers must be adapted to run in such conditions.
Ports both data collectors will have performance problems if used consistently within or refrigerated areas often exposed to extremes of temperature.
The cold environment can become a major problem for the visibility of the LCD screen and can also cause malfunctions in the equipment.
Also, if the ice covering the local image capture and optical devices will not work. In this scenario, workers would have to resort to manual data entry, running the risk of errors.
Condensation
And ice, condensation can cause problems on the screens and scanners to be unusable. However, condensation is a more serious problem because it can occur inside the display screen scanning, making it difficult to be eliminated, and ultimately cause problems in the internal parts causing corrosion or short circuit.
Refrigerated Air Conditioning
When the temperature falls below a certain level, the batteries are not able to release its energy, causing the battery-powered mobile devices to slow down and reduce its overall efficiency.
Moreover, radio waves travel differently in cold air, so users can experience less ranging from their systems of wireless LAN.
Insulation
The insulation used to keep the cold air can restrict the movement of radio waves, it absorbs RF signals, creating an effect that causes the signals to bounce off obstacles and reach the access points at different times.
If you take your mobile computer in a freezer or other cold area for a short period of time, the mobile computer will not stop working.
Computers mobile standard will be submitted with the normal function down to about -10 ◦ F. However, the amount of exposure and the frequency of transition from cold to hot should curtoespaço time in damaging it
What is the difference between thermal printers and thermal transfer?
Both are used in printing bar codes. Thermal printers have a printing system by heating controlled by a microprocessor in heat-sensitive paper. Printers thermal transfer ribbon using a tape, eliminating the use of thermal paper, as the heat warms the ribbon which transfers the printing to plain paper.

3.1 What is the RSS code?
The reduced space symbology RSS - Reduced Space Symbology - is a family of linear bar code capable of encoding the number of global trade item EAN / UCC 14 digits. The RSS seeks to bring the benefits of a complete identification of the product as well as other applications in the supply chain, when what has to be identified, has limited space and the existing linear symbologies could not normally be used.
3.2 What are the main types of RSS code?
The main versions of RSS code are:
RSS-14: This compact linear symbol encodes a GTIN (Global Trade Item Number, or the overall number of commercial item of 14 digits) and, optionally, a code indicating a connection with the two-dimensional symbol that conveys information.
RSS-14 stacked (stacked): this version of the RSS symbology encodes the 14-digit GTIN. It is presented in two segments of "lines". This profile enables you to use more favorable than available space.
RSS-14 Limited (limited): This version encodes 14 digits with the restriction that the first digit (number indicator, also known as variant logistics) has the value "1" or "0". Therefore, it can encode the full extent of the 14 numbers EAN / UCC. Yet he supports the numbers EAN/UCC-8, UCC-12 and EAN/UCC-13.
RSS Expanded (expanded) version RSS Expanded encodes up to 72 numeric or 42 alphabetic. The symbol encodes the GTIN, or other identification number EAN / UCC, in addition to additional data when required.
3.3 What is the difference between RFID and bar code?
RFID technology is not intended to replace the bar code on all its applications. RFID should be viewed as an additional method of identification used in applications where the bar code and other tracking technologies do not meet all needs, yet can be used alone or in combination with some other method of identification. Each label type has its advantages, and what we need is to know to enjoy the best benefits of each technology to build an ideal solution. The primary benefits of RFID are: the elimination of clerical and data reading, data collection faster and more automatic, reducing data processing and enhanced security. The advantages of RFID over other technologies for the identification and collection of data, we have: safe operation in harsh environment (damp places, wet, dirty, corrosive, high temperature, low temperature, vibration, shock), operating without contact and without need visual field and a variety of shapes and sizes.
3.4 What the main applications of RFID?
The RFID system can be used in people, places, objects and animals. Among the main applications of this technology include:
Identification of vehicles and containers;
Traceability of products;
Baggage handling at airports;
Tracking animals;

4.1 What the security of a wireless network?
The IEEE 802.11 provides the Service Set Identification (ESSID or SSID) and encryption of information traffic between the radio signals, which can be up to 128-bit (WEP). The Cisco 350 series has been active in the IEEE 802.1x Extensible Authorization Protocol (EAP) security which, together with RADIUS, provides total security.
4.2 What the baud rate that can be accessed on the radio?
As standardization of IEEE 802.11, FH technology can achieve 2 Mbps, with technology DS is reached 11 Mbps (according to standards IEEE 802.11b).
4.3 on equipment you may have within the same radio cell?
The IEEE is not standardized this feature. So this amount depends on each manufacturer. The equipment of Cisco Aironet allow up to 2048.
4.4 What is the standard IEEE 802.11?
The 802.11 standard was developed by the IEEE (Institute of Electrical and Electronics Engineers) for wireless local area networks (WLANs). The purpose of this standard is to develop a standard to provide a "Medium Access Control (MAC) and Physical Layer specific to wireless workstations with fixed or mobile within a local network. This standard defines the types of protocols necessary to allow interoperability between network equipment for wireless manufacturers.
The 802.11 standard can be compared to patterns of local wired network 802.3 and 802.5 for Ethernet and Token-Ring. With these patterns you can work with different equipment from different manufacturers and with great efficiency. This comparison takes into account the differences between wired and wireless, such as bandwidth, security, address etc..
4.5 Every equipment operating in the 2.4GHz frequency are within the IEEE 802.11?
Equipment operating within the IEEE 802.11 is a need to use the frequency range 2.4 GHz Before we set this standard, many manufacturers already operating in the frequency range of 2.4 GHz, but making use of proprietary protocols . Therefore these devices are not necessarily within the norm.
4.6 It is possible to install access points in the same place from different manufacturers complying with the IEEE 802.11?
Not recommended. Some manufacturers deploy resources at access points where they exchange information, streamlining the communication equipment that are connected to them. This exchange of information between access points is only possible if the equipment is the same manufacturer, as these features are not described in the standards of the IEEE standardization.
4.7 Which of the two technologies are standardized by the IEEE: FH or DS?
The IEEE, under the number 802.11, standardized the two concepts of data transmission in the spread spectrum technology. Although FH and DS are standardized, there are some differences between them. IEEE, seeking an increase in the rate of transmission, created the 802.11b standard, which determines a transmission rate of up to 11 Mbps, which can only be achieved with the DS technology.
4.8 What are the trends for the IEEE 802.11a and IEEE 802.11b?
The 802.11b standard is a reality, while 802.11a is still in its early stage, and go through several changes. Today it is possible to meet almost every need with 802.11b, because there are VoIP, that when you have a well-designed network can be obtained excellent results with wireless IP phones. In the case of 802.11a there are still some issues to be resolved over time, one of which is the cost of equipment, there is also a need for a large number of access points to cover the same area already covered by 802.11 Access Points b. Today we have seen more and more customers seeking to increase network bandwidth and not always the problem is there, it is enough to make a good network design to a speed of 10 Mbps and still serves very well. Therefore, we believe that the 802.11b (11 Mbps) will meet the needs of users for many years.
4.9 What is PAN, WAN and LAN?
PAN - Personal Area Networks are based on a global specification called Bluetooth, which uses radio frequency technology to transmit voice and data. This type of system of data transmission has a limited coverage area. These networks have the main functionality to replace the peripherals connected to the computer.
WAN - Wide Area Networks operating systems for digital mobile phones to transmit data and information from any location.
LAN - The wireless local area networks (WLANs) are formed as an alternative to conventional wired networks, providing the same functionality but in a flexible, easy configuration and good connectivity in areas of buildings or campus. Depending on the technology used - radio frequency or infrared, and the receiver, the WLAN network can reach distances of up to 40 kilometers. Thus, WLANs combine the mobility of the User connectivity at high speeds of up to 11 Mbps, in some cases. Currently, WLANs are standardized internationally by the 802.11 protocol, agreed by the IEEE to manufacturers. For solutions that adopt this standard gives the name of WI - FI (Wireless Fidelity).
