4G LTE
— Fourth Generation Long Term Evolution. LTE is a standard for wireless data communications
technology and an evolution of the GSM/UMTS standards. The goal of LTE is to increase the capacity
and speed of wireless data networks using new DSP (digital signal processing) techniques and
modulations that were developed around the turn of the millenium. A further goal is the redesign and
simplification of the network architecture to an IP-based system with significantly reduced transfer
latency compared to the 3G architecture. The LTE wireless interface is incompatible with 2G and 3G
networks, so that it must be operated on a separate wireless spectrum.
●
802.11 (a, b, g, n,ac)
— A set of WLAN Wi-Fi communication standards in the 2.4 and 5 GHz
frequency bands.
●
bps
— Bits per second. The rate of data flow.
●
Broadband
— High-capacity high-speed transmission channel with a wider bandwidth than
conventional modem lines. Broadband channels can carry video, voice, and data simultaneously.
●
DHCP
— Dynamic Host Configuration Protocol. Software found in servers and routers that
automatically assigns IP addresses and other configuration data to computers, tablets, printers, and
other devices connected to the IP network.
●
DHCP Server
— A server or service with a server that assigns IP addresses.
●
DNS
— Domain Name System. A system for converting host names and domain names into IP
addresses on the Internet or on local networks that use the TCP/IP protocol.
●
Firmware
— A computer program embedded in an electronic device. Firmware usually contains
operating code for the device.
●
GB
— Gigabyte. A multiple of the unit byte for digital information storage. Usage depends on context.
When referring to disk capacities it usually means 10
9
bytes. It also applies to data transmission
quantities over telecommunication circuits.
●
Gbps
— Gigabits per second. The rate of data flow.
●
Hotspot
— A Wi-Fi (802.11) access point or the area covered by an access point. Used for connecting
to the Internet.
●
HTTP
— Hypertext Transfer Protocol. An application-level protocol for accessing the World Wide Web
over the Internet.
●
IEEE —
Institute of Electrical and Electronics Engineers. An international technical/professional society
that promotes standardization in technical disciplines.
●
IMEI
— International Mobile Equipment Identity. Used in LTE networks to identify the device. It is
usually printed on the device and can often be retrieved using a USSD code.
●
IP
— Internet Protocol. The mechanism by which packets are routed between computers on a
network.
●
IP Type
— The type of service provided over a network.
●
IP address
— Internet Protocol address. The address of a device attached to an IP network (TCP/IP
