numbers, but they are usually stored in text files and displayed in
human-readable notations, such as decimal nnn.nnn.nnn.nnn or
172.16.255.1 (for IPv4), and hexadecimal
nnnn.nnnn.nnnn.nnnn.nnnn.nnnn.nnnn.nnnn or
2C01:AB18:0:1234:FF03:567C:8:1 (for IPv6). In IPv4, each decimal
group (nnn) represents values from 000 to 255, or binary values of 8
bits. In IPv6, each hexadecimal group (nnnn) represents values from
0000 to FFFF, or binary values of 16 bits (0000 0000 0000 0000 to 1111
1111 1111 1111).
IPv6 : Internet Protocol Version 6 (IPv6) is a numerical label that is used to
identify a network interface of a computer or other network node
participating in an IPV6-enabled computer network. IPv6 uses 128 bits
for the address (as compared to an IPv4 address, which is defined as a
32-bit number). IPv6 was developed in 1995, and it is standardized as
RFC 2460. IPv6 began being deployed worldwide in the year 2000. IP
addresses are binary numbers, but they are usually stored in text files
and displayed in human-readable notations, such as hexadecimal
nnnn.nnnn.nnnn.nnnn.nnnn.nnnn.nnnn.nnnn or
2C01:AB18:0:1234:FF03:567C:8:1 (where FFFF [Hex] = 65535 [Dec]).
Each hexadecimal group (nnnn) represents values from 0000 to FFFF,
or binary values of 16 bits (0000 0000 0000 0000 to 1111 1111 1111
1111).
LPA : Linear Power Amplifier (LPA) is the final amplification stage in a
multicarrier transmitter that has been designed and optimized to
produce a linear response. By operating in the linear mode, the
amplifier reduces the non-linear effects that produce intermodulation
products and side-lobe spectra that cause adjacent channel interference.
NF : Noise Figure (NF) is a measure of degradation of the signal-to-noise
ratio (SNR) that is caused by components in a radio frequency (RF)
device. The noise factor (F) of a system is defined as the signal-to-noise
ratio of the input power of the system divided by the signal-to-noise
ratio of the output power of that system. NF (the noise figure) is defined
as the decibel value of the noise factor. NF = 10log (F) where log uses
the base 10, or common log. This formula is valid only then the input
termination is at standard noise temperature.
OBW : Occupied Bandwidth (OBW) Occupied Bandwidth is a measure
of the bandwidth containing 99% of the total integrated power of the
transmitted spectrum, centered on the assigned channel frequency.
Interference to other channels or to other systems can occur if
OWB is too large.
OTA : Over The Air (OTA): OTA refers generally to any transfer of information
or signal that takes place in a wireless environment, rather than using
a wired connection. OTA is usually used in connection with a standard
defining the provisioning of mobile devices and applications, such as
downloading or uploading content or software, and commonly used in
conjunction with the Short Messaging Service (SMS). SMS OTA
Messages contain information that is used to configure the settings of a
WAP browser in a mobile phone (refer to SMS and WAP).
