Emerson Ensures Safety In Wireless Technology

Source(google.com.pk)

Emerson Process Management, a leader in automation technology and services, said it designs its technologies using the most advanced techniques for a safer wireless usage.

Wireless is the next inflection point in the process industries, and hesitant adopters should realise that they should leverage this innovation now if they do not want to fall further behind the curve, said a statement.

Wireless technologies connect people worldwide irrespective of time and place. In the process industries, the same technologies are used by organisations to improve their operations, particularly in the areas of maintenance, security, and health safety and environmental (HSE) performance.
Wireless is now implemented in thousands of industrial facilities across the world. An important event that caused this widespread adoption was the creation of a multi-vendor, interoperable industry standard.

The international standard IEC62591 or WirelessHART is the first standard developed specifically to meet the needs of the process industries. It was established by the HART Communication Foundation (HCF) in collaboration with end-users, process equipment vendors, and engineering and communication experts, said the statement.

WirelessHART was ratified in September 2007 by the HCF and approved by the International Electrotechnical Commission (IEC) in 2010, it said.

Organisations are now moving to wider and more complex wireless implementation.

In the oil and gas sector, for instance, pump and steam trap monitoring used to be a lengthy and expensive process involving physical inspection and laborious data collection in distant field and plant locations. With wireless technologies, operators can now obtain equipment health information remotely.

Numerous organisations have also started to implement plant-wide tracking applications to address workforce productivity, security, and HSE performance. These tracking applications offer varying degrees of location accuracy depending on budget and business needs.

For standard tracking, plant operators use wifi Active Radio-Frequency Identification (RFID) access badges to ensure that people are allowed or restricted to enter specific plant areas according to their roles, and that the movement of assets from one plant area to another is monitored in real time.

The concern of security in using wireless is now being addressed by business like Emerson, that design technologies with multi-tiered, always-on security systems.

Fort Nelson, B.C. - TELUS announced today that it has brought the world's most advanced and fastest wireless technology to customers in Fort Nelson.

This expansion of TELUS' 4G Long Term Evolution (LTE) network coverage means that area residents and visitors can take advantage of dramatically faster speeds when surfing the web, reading emails or sharing photos from their wireless devices.

TELUS rolled out 4G LTE to almost 90 per cent of British Columbians in 2012 and plans to connect even more by the end of 2013.

"TELUS' expansion of our 4G LTE network to Fort Nelson will bring Internet speeds as fast as what customers experience at home to their cell phone, tablet or Internet key while on the move," said Lance MacDonald, TELUS General Manager for Northern British Columbia. "Our 4G LTE network will cover the downtown city core of Fort Nelson and the gas fields, allowing residents to stay connected to the online world with the latest smartphones like the HTC One and Samsung Galaxy S4, whether they're sharing photos or video clips with friends on social media or getting some work done on the fly."

4G LTE is rapidly emerging as the new standard for wireless technology in the world, with most new handsets built to take advantage of its superior speed. TELUS customers can already experience the full capabilities of TELUS' 4G LTE network with the popular HTC One, BlackBerry Q10, Samsung Galaxy S4, Samsung Galaxy Note II, Samsung Rugby LTE, Samsung ATIV S, LG Optimus G, HTC One X+, Huawei E397 4G LTE Mobile Internet Key and Samsung Galaxy Tab 8.9 LTE. Consistent with TELUS' clear and simple pricing approach, current rate plans will apply to all TELUS 4G LTE customers without premium charges.

TELUS' 4G LTE network supports manufacturers' top download speeds of up to 75 megabits per second (Mbps), with an expected average of 12 to 25 Mbps depending on signal strength. Using 4G LTE, TELUS customers will experience dramatically faster and seamless downloads when surfing the web, reading emails or getting the latest chart topping music. For example, downloading a 600 megabyte album with a 4G LTE-capable device will only take 3.5 to 7 minutes, while a 1.2GB HD movie from iTunes will be ready for viewing in just 7 to 14 minutes. Most importantly, TELUS customers will move seamlessly from 4G LTE to the existing 4G HSPA networks when roaming out of areas with LTE, and will have no disruption to wireless service or downloading.

4G LTE is the latest evolution in TELUS' wireless network technology rollout, building on the 2009 launch of its coast-to-coast 4G HSPA wireless network. Today the HSPA wireless network reaches more than 97 per cent of Canadians. Since 2000, TELUS has invested more than $30 billion to bring Canadians some of the most advanced wireless networks in the world. This investment is part of the $3 billion TELUS is investing in new infrastructure and facilities in B.C. from 2012 to 2014.

Additionally, TELUS is putting customers first and embracing new ideas to make the TELUS experience even better. Listening to customers, TELUS has launched Canada's first network experience mobile application, giving customers an easy way to report network issues. The company has also eliminated activation fees and dramatically simplified its entire fee schedule. This builds on a series of improvements where TELUS eliminated carrier 911 and system access fees on all its Clear and Simple rate plans; reduced bill shock with Flex Data Plans, Data Notifications and travel roaming packages; added Caller ID and Voicemail as standard on all TELUS rate plans; simplified device pricing with Anytime Upgrades; and revolutionized mobility contracts by introducing a Device Balance instead of a contract termination fee.

Wireless WiFi Technology
WiFi is a wireless technology which allows devices to inter-connect and communicate with each other. Radio waves are electromagnetic waves and have different frequencies. This technology is a radio frequency. Similar to the analogue radio, or FM radio. WiFi works in two frequency bands 2.4GHz and 5GHz.

WiFi or Wireless Fidelity, has a range of about 100m and allows for faster data transfer rate between 10 - 54Mbps. There are three different wireless standards under WiFi, 802.11a, 802.11b and 802.11g. 802.11 being the wireless standard set by The Institue of Electrical and Electronic Engineers (IEEE). WiFi is used to create wireless Local Area Networks (WLAN). The most widely used standard is 802.11b and 802.11g is expexcted to grow rapidly. These two standards are relatively inexpensive and can be found providing wireless connectivity in airports, railway stations, cafes, bars, restaurants and other public areas. The main difference between the two is the speed. 802.11b has data transfer rate of upto 11Mbps and 802.11g has a rate of upto 54Mbps. 802.11g is a relatively new and has yet to be adopted widely. 802.11a is more expensive and as a result it not available for public access.

Wireless WiMAX Technology
WiMAX is a wireless technology which allows devices to inter-connect and communicate with each other. Radio waves are electromagnetic waves and have different frequencies. This technology is a radio frequency. Similar to the analogue radio, or FM radio. WiMAX works in two frequency bands, 2 - 11GHz and 10 - 66GHz.

WiMAX is Worldwide Interoperability for Microwave Access. The IEEE standard for WiMAX is 802.16 and falls under the category of wireless Metropolitan Area Network (WMAN). WiMAX operates on two frequency bands, 2 - 11GHz and 10 - 66GHz and has a range of about 50km with speeds of upto 80Mbps. This enables smaller wireless LANs to be interconnected by WiMAX creating a large wireless MAN. Networking between cities can beachieved without the need for expensive cabling. It is also able to provide high speed wireless broadband access to users. As it can operate in two frequency bands WiMAX can work by line-of-sight and non-line-of-sight. At the 2 - 11GHz frquency range it works by non-line-of-sight, where a computer inside a building communicates with a tower/antenna outside the building. Short frequency transmissions are not easily disrupted by physical obstructions. Higher frequency transmissions are used for non-line-of-sight service. This enables to towers/antennae to communicate with each other over a greater distance. Due to infrastructure and costs involved it would be more suited to provide the backbone services for ISPs and large corporations providing wireless networking and internet access.

Wireless Bluetooth v4.0

Source(google.com.pk)
Wireless Bluetooth v4.0
Bluetooth is a wireless technology which allows devices to inter-connect and communicate with each other. Radio waves are electromagnetic waves and have different frequencies. This technology is a radio frequency. Similar to the analogue radio, or FM radio. Bluetooth works on 2.45GHz frequency.

The Bluetooth SIG completed the Bluetooth Core Specification version 4.0 and has been adopted as of 30 June 2010. It includes Classic Bluetooth, Bluetooth high speed and Bluetooth low energy protocols. Bluetooth high speed is based on Wi-Fi, and Classic Bluetooth consists of legacy Bluetooth protocols.

Bluetooth low energy (BLE), previously known as WiBree, is a subset of Bluetooth v4.0 with an entirely new protocol stack for rapid build-up of simple links. As an alternative to the Bluetooth standard protocols that were introduced in Bluetooth v1.0 to v3.0, it is aimed at very low power applications running off a coin cell. Chip designs allow for two types of implementation, dual-mode, single-mode and enhanced past versions. The provisional names Wibree and Bluetooth ULP (Ultra Low Power) were abandoned and the BLE name was used for a while. In late 2011, new logos “Bluetooth Smart Ready” for hosts and "Bluetooth Smart" for sensors were introduced as the general-public face of BLE.
  • In a single mode implementation the low energy protocol stack is implemented solely. CSR, Nordic Semiconductor and Texas Instruments have released single mode Bluetooth low energy solutions.
  • In a dual-mode implementation, Bluetooth low energy functionality is integrated into an existing Classic Bluetooth controller. Currently (2011-03) the following semiconductor companies have announced the availability of chips meeting the standard: Qualcomm-Atheros, CSR, Broadcom and Texas Instruments. The compliant architecture shares all of Classic Bluetooth’s existing radio and functionality resulting in a negligible cost increase compared to Classic Bluetooth.
Cost-reduced single-mode chips, which enable highly integrated and compact devices, feature a lightweight Link Layer providing ultra-low power idle mode operation, simple device discovery, and reliable point-to-multipoint data transfer with advanced power-save and secure encrypted connections at the lowest possible cost.

General improvements in version 4.0 include the changes necessary to facilitate BLE modes, as well the Generic Attribute Profile (GATT) and Security Manager (SM) services with AES Encryption.

Core Specification Addendum 2 was unveiled in December 2011; it contains improvements to the audio Host Controller Interface and to the High Speed (802.11) Protocol Adaptation Layer.

Bluetooth vs Wi-Fi

Bluetooth vs Wi-Fi
Bluetooth and Wi-Fi (the brand name for products using IEEE 802.11 standards) have some similar applications: setting up networks, printing, or transferring files. Wi-Fi is intended as a replacement for cabling for general local area network access in work areas. This category of applications is sometimes called wireless local area networks (WLAN). Bluetooth was intended for portable equipment and its applications. The category of applications is outlined as the wireless personal area network (WPAN). Bluetooth is a replacement for cabling in a variety of personally carried applications in any setting and also works for fixed location applications such as smart energy functionality in the home (thermostats, etc.).

Wi-Fi is a wireless version of a common wired Ethernet network, and requires configuration to set up shared resources, transmit files, and to set up audio links (for example, headsets and hands-free devices). Wi-Fi uses the same radio frequencies as Bluetooth, but with higher power, resulting in higher bit rates and better range from the base station. The nearest equivalents in Bluetooth are the DUN profile, which allows devices to act as modem interfaces, and the PAN profile, which allows for ad-hoc networking.

Bluetooth exists in many products, such as telephones, tablets, media players, Lego Mindstorms NXT, PlayStation 3, PS Vita, the Nintendo Wii, and some high definition headsets, modems, and watches. The technology is useful when transferring information between two or more devices that are near each other in low-bandwidth situations. Bluetooth is commonly used to transfer sound data with telephones (i.e., with a Bluetooth headset) or byte data with hand-held computers (transferring files).

Bluetooth protocols simplify the discovery and setup of services between devices. Bluetooth devices can advertise all of the services they provide. This makes using services easier because more of the security, network address and permission configuration can be automated than with many other network types.

Wireless Bluetooth Technology
Bluetooth is a wireless technology which allows devices to inter-connect and communicate with each other. Radio waves are electromagnetic waves and have different frequencies. This technology is a radio frequency. Similar to the analogue radio, or FM radio. Bluetooth works on 2.45GHz frequency.

Bluetooth: Named after the Danish king, Harold Bluetooth,was the first to emerge, several devices like mobile phones, PDAs, headsets, keyboards, mice, medical equipment and even cars now come with this feature. Due to its low cost, manufacturers are willing to implement this technology in most devices. It is designed for short range communications with a range of about 10m. As a result, it consumes less power and are suited for very small battery powered devices and portable devices. Problems associated when devices communicate via infrared or cables are removed. Infrared requires a line of sight, bluetooth only needs to be in reasonable vicinity. As cables are not required, it would be less cumbersome carrying a personal bluetooth device and space would be less cluttered. As Bluetooth devices automatically communicate with each other, it requires very little from the user. Bluetooth allows for a wireless Personal Area Network (PAN) with it's short range.

Computer requirements:
A personal computer that does not have embedded Bluetooth can be used with a Bluetooth adapter that will enable the PC to communicate with other Bluetooth devices (such as mobile phones, mouse and keyboards). While some desktop computers and most recent laptops come with a built-in Bluetooth radio, others will require an external one in the form of a dongle.

Unlike its predecessor, IrDA, which requires a separate adapter for each device, Bluetooth allows multiple devices to communicate with a computer over a single adapter.

Bluetooth v3.0 + HS
Version 3.0 + HS of the Bluetooth Core Specification was adopted by the Bluetooth SIG on 21 April 2009. Bluetooth 3.0+HS provides theoretical data transfer speeds of up to 24 Mbit/s, though not over the Bluetooth link itself. Instead, the Bluetooth link is used for negotiation and establishment, and the high data rate traffic is carried over a collocated 802.11 link.

The main new feature is AMP (Alternate MAC/PHY), the addition of 802.11 as a high speed transport. The High-Speed part of the specification is not mandatory, and hence only devices sporting the "+HS" will actually support the Bluetooth over 802.11 high-speed data transfer. A Bluetooth 3.0 device without the "+HS" suffix will not support High Speed, and needs to only support a feature introduced in Core Specification Version 3.0 or earlier Core Specification Addendum 1.
