connection where at each connection a new address is assigned, and for DSL services where the address
is changed occasionally by the ISP. Bytton LTE allows usage of Dynamic DNS.
Domain Name Resolution -
The resolving of a domain name. Internet applications don’t communicate
with domain names such as google.com or topex.ro, instead they use IP addresses (for example
193.226.61.95 or 216.239.39.99). Domain Name Resolution is the process (transparent for the user) of
converting domain names into corresponding IP addresses. Every operating system has routines that deal
with resolution of domain names.
Encryption
- This provides wireless data transmissions with a level of security. Bytton provides various
degrees of encryption for data sent out via its embedded Wi-Fi access point.
Ethernet
- Standard for wired computer networks. Ethernet networks are connected by cables and hubs,
and move data around. For wired connections, Bytton LTE provides Ethernet 10/100 ports, three for the
local LAN and one for WAN. The ports are fully configurable, from the Web interface you may join the
three LAN ports in the same switch or not, assign the different Ips, set them to operate duplex or half-
duplex, select data speeds of 10 or 100 Mps, enable or disable auto-negotiation, and so on.
Firewall
- System designed to prevent unauthorized access to or from a private network. The firewall
determines which information passes in and out of and prevents anyone outside of your network from
accessing your computer without authorization and possibly damaging or viewing your files. Any company
with an intranet that allows its workers access to the wider Internet must use a software or hardware
firewall to prevent outsiders from accessing its own private data resources and for controlling what outside
resources its own users have access to. Here the firewall is software a set of related programs (residing
on the gateway server) that protect the resources of the local (internal) network.
Gateway
- A network point that manages all the data traffic of your network, as well as to the Internet and
connects one network to another. Bytton LTE is also gateway, since it interfaces between the local
networks (wired or wireless) and the HSPA mobile network or another broadband connection.
GRE
– Acronym for Generic Routing Encapsulation. GRE is used as a tunneling protocol, which can
encapsulate a wide variety of protocol packet types inside IP tunnels. IP tunneling using GRE protocol
allows easy creation and expansion of a Virtual Private Network using the 3G+ mobile network. The
Bytton LTE router from Rohde & Schwarz Topex S.A. allows you to use several different GRE tunnels.
HSDPA
(High-Speed Downlink Packet Access) is an enhanced 3G (third generation) mobile telephony
communications protocol in the High-Speed Packet Access (HSPA) family, also refered as 3.5G, 3G+ or
turbo 3G. HSPDA allows mobile networks based on UMTS to have higher data transfer speeds and
capacity. Current HSDPA deployments support down-link speeds of up to 42 Mbit/s. Further speed
increases are available with HSPA+, which provides speeds of up to 337 Mbit/s with Release 11 of the
3GPP standards.
HSPA+,
also called "I-HSPA" (for Internet-HSPA) or Evolved High-Speed Packet Access, is a wireless
broadband standard defined in 3GPP release 7 and above. By its name you can see that HSPA+ is an
enhanced version of the previous 3G+ High Speed Packet Access system, a further increase of the
speeds of the basic 3G system, and another step towards 4G (data rates up to 42Mbps currently and 100
Mbps in the LTE networks)!
IP Address
– Short from Internet Protocol address. The numerical address of a network device or
resource as expressed in the format specified in the Internet Protocol (IP). In the current addressing
format, IP version 4, the IP address is a 32-bit (4 bytes) sequence divided into four groups of decimal
numbers separated by periods ("dots"). Each number can be zero to 255. These four groups of numbers
look like “127.0.0.1” or „213.154.120.170”. The four numbers in an IP address are used in different ways
to identify a particular network and a host on that network.
IP
– Acronym for Internet Protocol. It is the protocol from TCP/IP that directs the way data is sent from one
computer to another on the Internet. The messages are divided into data packets, routed from the sender
network to the receiver network and there re-assembled in the right order to re-create the original
message. Because a message is divided into a number of packets, each packet can, if necessary, be sent
by a different route across the Internet. These data packets can arrive in a different order than the order
they were sent in. The Internet Protocol just delivers them. It's up to TCP protocol (Transmission Control
Protocol ) to put the packets back in the right order.
