CIS 513 Assignment One Unicode & Frequency Hopping Spread Spectrum (FHSS) Name School Class Professor Dates Abstract Unicode provides a standardized means for text in nearly any language to be shared across the Internet. Consistency Hopping Get spread around Spectrum can be described as means by which in turn transmissions “hop” between various frequencies, decreasing the transmission’s vulnerability to outside resources. Assignment A person Unicode The world is progressively more shrinking when new technology are providing people and the cultures in closer connection with each other. Two technologies which have been helping attempt are cellular computing in its various varieties and Unicode. To understand essential Unicode is usually to the future of the world wide web and computer, first we must understand why Unicode was developed. Their main forerunner, the American Standard Code for Information Interchange (ACSII), which can be “stored when 1 octet (8 bits) in binary code. ” (Olenewa, L. & Ciampa; M. (2007) However , “one of the constraints of ASCII is that you will find not enough language for all the symbols used by foreign languages. ” (Olenewa, J. & Ciampa, M.; 2007) Additionally , ACSII is only useful for up to 128 different rules. Unicode breaks this barrier by using 2 bytes (16 bits) in order to represent nearly all of the languages of the world. From this it’s not too much of a leap to see that using Unicode is useful to global businesses in a variety of ways. As these global businesses become more mobile, relying on wireless technologies to do business, some of the top benefits of Unicode are, “Text in any language can be exchanged worldwide” meaning that it “Eliminates data corruption and other problems due to incompatible pages of missing conversion tables. ” (Texin, T., 2003) “Widespread industry support provides platform and vendor independence” (Texin, T., 2003) allows cross-operating systems (OSs) to openly exchange information without concern that the languages exchanged may not be compatible with a unique OS. As well as the last key benefit with respect to global firms is that Unicode “allows with respect to multilingual textual content using any languages you want. ” (Texin, T., 2003) An example of this can be that “invoice or ticketing applications may print consumer information within their native different languages from just one database. ” (Texin, Testosterone levels., 2003) These types of three rewards and articles are just first what global businesses are trying to find to effectively compete. Conceivably a simpler method to express for what reason Unicode is a superb thing with respect to globalization are available in Richard Cook’s “Unicode gives people what they want. ” The five terms, “data, easy, find, give, keep” (Cook, R., 2001) express this idea neatly. “Data” means they want a variety of useful information. “Easy” it should be inexpensive. “Find” means it should be accessible. “Give” means the transfer of data that can be easily swapped. And “keep” means that the information should be available for a very long time and that once bought it should not have to be reacquired. He says it best, “Unicode support is actually a modest long term investment that will have big future payoffs. Building Unicode support unwraps and helps to keep open doors to rich info. ” (Cook, R., 2001) What does this kind of all must do with a cellular environment? Taking a look at Mr. Cook’s five ideas another way, Unicode facilitates use of any information around the globe in nearly all language within an easy and cost-effective manner. This is just what businesses demand not only with regard to their employees but in addition for the customers that frequent these kinds of global corporations. Frequency Jumping Spread Variety (FHSS)

A person alternative to limit band a radio station frequency (RF) transmissions is certainly spread variety transmissions. Limit band RF means that tranny and reception occurs on only one specific frequency. This really is a simple method, but is usually “vulnerable to outside interference from an additional signal. ” (Olenewa, J. & Ciampa, M.; 2007) Frequency Hopping Spread Spectrum (FHSS) may be the one method through which spread spectrum can be accomplished. “With FHSS, a short burst open is transmitted at 1 frequency after which a short burst open is transmitted at an additional frequency, and so on until the tranny is completed. ” (Olenewa, J. & Ciampa, M.; 2007) FHSS provides two main disadvantages in comparison to Direct Series Spread Spectrum (DSSS), an additional method of distributed spectrum: “Greater tolerance of signal interference because of operation over wider (83. five MHz) band width, and Power to operate about 10 collocated access things without significant interference. ” (Geier, L.; 2000) FHSS also has 3 main cons to DSSS: “Lowers potential data costs from specific physical tiers, Less range than direct sequence because of need for in least 18dB SNR in receiver, and Potential obsolescence as more companies carry on and favor the higher-speed (802. 11b) direct sequence products. ” (Geier, J.; 2000) These drawbacks not-withstanding, many commercial applications use FHSS, including cordless phones and multi-handset products for business. (Olenewa, M. & Ciampa, M.; 2007) Bluetooth (IEEE Standard 802. 15. 12002) also uses FHSS. Although not strictly FHSS, one army application that is similar to FHSS, is the AN/WSC-3(V)11 transceiver. Also called the Have got Quick transceiver, it operates in a rate of recurrence hopping method that is very similar to FHSS. Recommendations Olenewa, M. & Ciampa, M. (2007).
