Please answer the following question: Information: - Minnesota (locally ) is a state in the midwestern and northern regions of the United States. Minnesota was admitted as the 32nd U.S. state on May 11, 1858, created from the eastern half of the Minnesota Territory. The state has a large number of lakes, and is known by the slogan "Land of 10,000 Lakes". Its official motto is "L'Etoile du Nord" (French: "Star of the North"). Minnesota is the 12th largest in area and the 21st most populous of the U.S. states; nearly 60 percent of its residents live in the MinneapolisSaint Paul metropolitan area (known as the "Twin Cities"), the center of transportation, business, industry, education, and government and home to an internationally known arts community. The remainder of the state consists of western prairies now given over to intensive agriculture; deciduous forests in the southeast, now partially cleared, farmed and settled; and the less populated North Woods, used for mining, forestry, and recreation. Minnesota is known for its progressive political orientation and its high rate of civic participation and voter turnout. Until European settlement, Minnesota was inhabited by the Dakota and Ojibwe/Anishinaabe. During the 19th and early 20th centuries, the large majority of the European settlers emigrated from Scandinavia and Germany, and the state remains a center of Scandinavian American and German American culture. In recent decades, immigration from Asia, the Horn of Africa, and Latin America has broadened its historic demographic and cultural composition. Minnesota's standard of living index is among the highest in the United States, and the state is also among the best-educated and wealthiest in the nation. - Internet Protocol version 6 (IPv6) is the most recent version of the Internet Protocol (IP), the communications protocol that provides an identification and location system for computers on networks and routes traffic across the Internet. IPv6 was developed by the Internet Engineering Task Force (IETF) to deal with the long-anticipated problem of IPv4 address exhaustion. IPv6 is intended to replace IPv4. - XBee is the brand name of a family of form factor compatible radio modules from Digi International . The first XBee radios were introduced under the MaxStream brand in 2005 and were based on the IEEE 802.15.4 - 2003 standard designed for point - to - point and star communications at over-the - air baud rates of 250 kbit / s. Two models were initially introduced -- a lower cost 1 mW XBee and the higher power 100 mW XBee - PRO. Since the initial introduction , a number of new XBee radios have been introduced and all XBees are now marketed and sold under the Digi brand . The XBee radios can all be used with the minimum number of connections -- power ( 3.3 V ) , ground , data in and data out ( UART ) , with other recommended lines being Reset and Sleep . Additionally , most XBee families have some other flow control , input / output ( I / O ) , analog - to - digital converter ( A / D ) and indicator lines built in . A version called the programmable XBee has an additional on - board processor for user 's code . The programmable XBee and a new surface - mount version of the XBee radios were both introduced in 2010 . - USB, short for Universal Serial Bus, is an industry standard initially developed in the mid-1990s that defines the cables, connectors and communications protocols used in a bus for connection, communication, and power supply between computers and electronic devices. It is currently developed by the USB Implementers Forum (USB IF). - IEEE 802.15.4 is a technical standard which defines the operation of low-rate wireless personal area networks (LR-WPANs). It specifies the physical layer and media access control for LR-WPANs, and is maintained by the IEEE 802.15 working group, which defined the standard in 2003. It is the basis for the ZigBee, ISA100.11a, WirelessHART, MiWi, SNAP, and Thread specifications, each of which further extends the standard by developing the upper layers which are not defined in IEEE 802.15.4. Alternatively, it can be used with 6LoWPAN, the technology used to deliver the IPv6 version of the Internet Protocol (IP) over WPANs, to define the upper layers. - Digi International is an American M2M communications and technology company headquartered in Minnetonka, Minnesota. The company was founded in 1985 as DigiBoard and went public as Digi International in 1989. The company initially offered intelligent ISA/PCI boards (the 'DigiBoard') with multiple asynchronous serial interfaces for PCs. Nowadays, multi-port serial boards are still part of the product line-up, but the company is focusing on embedded and external network (wired and wireless) communication solutions as well as enterprise-class USB products. The company has a full line of radio modems and embedded modules based on current CDMA and GSM communications platforms. - MiWi and MiWi P2P are proprietary wireless protocols designed by Microchip Technology that use small, low-power digital radios based on the IEEE 802.15.4 standard for wireless personal area networks (WPANs). It is designed for low data transmission rates and short distance, cost constrained networks, such as industrial monitoring and control, home and building automation, remote control, low-power wireless sensors, lighting control and automated meter reading. - The Internet Protocol (IP) is the principal communications protocol in the Internet protocol suite for relaying datagrams across network boundaries. Its routing function enables internetworking, and essentially establishes the Internet. - In the IEEE 802 reference model of computer networking, the medium access control or media access control (MAC) layer is the lower sublayer of the data link layer (layer 2) of the seven-layer OSI model. The MAC sublayer provides addressing and channel access control mechanisms that make it possible for several terminals or network nodes to communicate within a multiple access network that incorporates a shared medium, e.g. an Ethernet network. The hardware that implements the MAC is referred to as a "media access controller". - GSM (Global System for Mobile Communications, originally Groupe SpecialMobile), is a standard developed by the European Telecommunications Standards Institute (ETSI) to describe the protocols for second-generation (2G) digital cellular networks used by mobile phones, first deployed in Finland in July 1991. it has become the de facto global standard for mobile communications with over 90% market share, operating in over 219 countries and territories. - 6LoWPAN is an acronym of "IPv6 over Low power Wireless Personal Area Networks". 6LoWPAN is the name of a concluded working group in the Internet area of the IETF. - Wireless communication is the transfer of information or power between two or more points that are not connected by an electrical conductor. The most common wireless technologies use radio. With radio waves distances can be short, such as a few meters for television or as far as thousands or even millions of kilometers for deep-space radio communications. It encompasses various types of fixed, mobile, and portable applications, including two-way radios, cellular telephones, personal digital assistants (PDAs), and wireless networking. Other examples of applications of radio "wireless technology" include GPS units, garage door openers, wireless computer mice, keyboards and headsets, headphones, radio receivers, satellite television, broadcast television and cordless telephones.
