Femtocells (aka Home Node B) are low-power wireless access points that operate in licensed spectrum to connect standard mobile devices to a mobile operator's network using residential DSL or cable broadband connections. This device has evolved out of the research that despite of large deployment of macrocell (BTS/BSC) in high density apartment areas and densely populated urban population, the signal...
GPRS or the general packet radio service is a non-voice value added technology that allows data communication over mobile phones in an Internet Protocol (IP)-based network [11]. This paper focuses on the transmission of voice over the existing data channel in GSM/GPRS networks using a Web server. Since the data channel in any network is economically viable for transmission, a mechanism to transfer...
SGSN and GGSN are the two core network elements of the general packet radio service which enables Internet to become mobile. It allows mobile users to access text based data services without continuously occupying a specific radio channel (which is not the case when you access voice channel). This paper successfully discusses the possibility of exploiting the data communication features of GGSN/SGSN...
The effects of heat stress during summer on the growth of Friesian calves were studied. The growth rate, daily solids gain, feed consumption and feed efficiency, serum concentrations of thyroxine, free thyroxine index, glucose, total protein, urea-N, creatinine, total lipids and total cholesterol, haemoglobin values and packed cell volume decreased significantly in summer as compared with winter conditions...
