There are many factors to consider when selecting the right tools to help transmit the Machine to Machine information:quantity of data, urgency of data, whether the unit is fixed or mobile, which wireless systems are available, and what distance needs to be covered to reach the nearest wired transmission. A shorter distance can be covered with a smaller surface mount omni-directional antenna that can be added directly to the device.
The ability to wirelessly transmit machine to machine information has made it possible to monitor remote locations which would otherwise be too difficult or too costly to monitor with wired communication. However, if more bandwidth is needed, then the user should be prepared to buy a 3G or 4G modem which may operate on the new 700 MHz LTE or 1.

Quantity of data: If the machine to machine information is transferred on a Cellular Network, a relevant question is: Will an older protocol such as GPRS suffice or will it be necessary to use a newer protocol such as LTE? If a GPRS modem will do the job, then only the 850 & 1900 MHz spectrum range will be used. However, from an antenna perspective at least, sometimes it is possible to select an antenna that is so broadbanded it can be used with a variety of applications.


Distance: Will a local area network be sufficient or is a wide area network needed? If the distance is relatively short, an unlicensed WiFi network can handle the transmitted machine to machine information, but if the distance covered is longer it would be better to choose either a Cellular Network or a WiMAX network.

This paper started with a simple statement but one that hides the complexity of the decisions and implementations behind such a decision. More information on the best antenna to use with machine to machine information is available on our website, www. Engineering and custom design services are available. The M2M unit could be attached to a WiFi network initially and then switched over to a cellular network as the data transmission requirements change. An additional manufacturing and sales facility is located near Birmingham, UK. The frequency spectrum over which the machine to machine information would be transmitted is licensed by the Cellular Carrier and a fee is

Urgency of data: Is there time to verify the accuracy of the data, will systems fail if the wireless network fails? The new MIMO systems, such as the 802. Unlicensed is cheaper but the network is shared so bandwidth can be an issue.

Mobile Mark, Inc.7 & 2. Cellular Systems fall in between.mobilemark. Choosing a broadband antenna, such as the RMM-WLF Surface Mount from Mobile Mark, allows the user to be prepared for any option. A dedicated licensed network might provide the highest level of privacy but be the most expensive. Antennas can be added to the network to extend the range covered. Each of these examples may benefit from a different style antenna. The nature and location of the machine to machine information to be transmitted will determine the best wireless system and wireless equipment to use. The antenna style will also contribute to the reliability of the Machine to Machine information Shrinking Machine transmitted.65 MHz broadband or unlicensed bands such as WiFi. Applications include GPS Tracking and Fleet Management, Cellular GSM/CDMA, LTE, WiMAX, WiFi, RFID, Public Safety, Military and Machine-to-Machine (M2M). For example, an externally mounted surface mount antenna will generally provide a more reliable connection than an embedded antenna.1 GHz AWS. Mobile Mark’s global headquarters, which includes research facilities and manufacturing plant, are located near Chicago, IL. For example, some remotely monitored devices, such as digital signs on the side of a highway, may be moved from location to location as the need for information changes. designs and manufactures site, mobile and device antennas for 137 MHz 10 GHz. Or contact Eleanor Sylvan, VP marketing, esylvan@mobilemark. A high gain directional antenna, such as a panel antenna, can provide extended point-to-point coverage. Each of these factors will influence the selection of wireless equipment, including the selection of the best antennas to facilitate the wireless connection. In general, it is important to select the network before selecting the equipment and antennas. Each of these options operates on a different frequency band.

Licensed or Unlicensed:Machine to Machine information can be transmitted over licensed bands such as 3.11n WiFi systems are designed to provide a more consistent, verifiable flow of data. These newer systems may be more expensive to install but may pay for themselves with more reliable data communications.

Fixed versus mobile: is the data always transmitted from the same location or does the transmission point move around? Data communications from a tower or a smart meter is pretty clearly fixed, and machine to machine information from a vehicle is pretty clearly mobile, but Sugar Packing Machine there is in fact a gray area in the middle. For example, the fixed location might require a high gain point-to-point directional antenna, the moveable device might require an omni-directional antenna since its orientation to other points in the network cannot be anticipated, and the vehicle antenna might require the addition of GPS to provide location information as well as data transmission
