Evolution from 2G to 3G
2G networks were built for the most part for voice data and slow communication. Due to rapid changes in user anticipation, they do not meet today's wireless requirements. Cellular mobile telecommunications networks are being improved to use 3G technologies from 1999 to 2010. Japan was the first country to introduce 3G nationally, and in Japan the transition to 3G was largely completed in 2006. Korea then adopted 3G Networks soon after and the transition was made as early as 2004.
From 2G to 2.5G (GPRS)
2.5G and even 2.75G are technologies such as i-mode data services, camera phones, high-speed circuit-switched data (HSCSD) and General Packet Radio Service (GPRS) that present some functionality domains like 3G networks, but not including the full transition to 3G network. They were built to set up the potentials of wireless application technology to the end customers, and so increase demand for 3G services. When converting a GSM network...
Export Business Plan: Moldovan Cellular Phones Purpose-Why has the plan been written? The plan has been written in order to guide our mobile phone export business. Cell phones in Moldova are rapidly overtaking land phones as many cellular phones now provide Internet access and cell phone computers. SMS, MMS and broadband are becoming standard features on cell phones. Nonetheless, mobile phones are expensive in Moldova and not everyone can afford them. Furthermore,
HSPA+ is expected to be commercially available in 2008 through [the introduction] of incremental investments and backward and forward compatible handsets. HSPA+ doubles the data capacity and increases voice capacity by three times enabling operators to offer mobile broadband at even lower cost" (Release 7 HSPA+, 2007, p. 3). Likewise, Housami (2008) reports that, "HSPA+ is a manifestation of the evolved HSPA philosophy where the existing HSPA implementation is
Though the technology in itself is not new (been used for more than two decades in military radar operations) only recently it has begun to be tested for business communications. Researchers point out UWB is at least 1000 times faster than currently used 802.11b or bluetooth technologies and hence could constitute an excellent alternative choice of protocol for local area networks, increasing their ability to cater to many more
According to Paul B. Mckimmy (2003), "The first consideration of wireless technology is bandwidth. 802.11b (one of four existing wireless Ethernet standards) is currently the most available and affordable specification. It allows a maximum of 11 megabits per second (Mbps)" (p. 111); the author adds that wired Ethernet LANs are typically 10 or 100 Mbps. In 1997, when the IEEE 802.11 standard was first ratified, wireless LANs were incompatible and
