Modem Routers

Router 3 G 3 G, often called 3 G modem, routers are teams whose function is to provide Internet access via mobile telephony to a device or to a local network machines, according to modem or router/modem. 3 G routers employ SIM card to validate the network, use of communication technology with better coverage by be multi-band (HSPA, 3 G, GPRS) and can be internal or external (PCMCIA, USB, Wi-Fi). Features 3 G modem and 3 G routers expressions are generic terms that are used interchangeably to refer to the electronic devices capable of providing access to the mobile Internet. In general, in places where there is the possibility of having a connection through a telephone landline ADSL or cable, these represent the best option for connecting to the Internet. But sometimes they can be suitable 3 G routers, if there is no coverage of fixed area connection or if it’s a project of short duration, despite the lower quality and higher cost of the connection. Modem or Router: Although both terms are colloquially used alike, they are not the same, 3 G routers enable Internet access to computers on a LAN, while modems only allow access to a single computer. SIM card: to authenticate to the network of the operator, 3 G routers must use SIM card, and can take it integrated or clip-on through slot.

Coverage: 3 G routers usually multi-band, using technology more appropriate coverage at each time, switching between 3 G, HSPA and GPRS without losing the connection, only modifying the bandwidth. Additional features: 3 G routers often have advanced networking such as firewall, DHCP server, DNS name server or packet filtering. Types have several options to achieve the functionality offered by devices called routers 3 G: 3 G Modem: no work as a router, modem, they only have function so it just give service to a single computer, do not allow to share the connection. They can be external, with interface PCMCIA or USB, or internal, when the modem is integrated in the computer itself. In addition, some 3 G USB modem have a Wi-Fi base that functions as a router. 3 G modem/Routers: acting as a modem and router, allowing to share the connection and that all machines on a local network can access the Internet simultaneously with a single external IP. They are external equipment, such as the so-called 3 G Wi – Fi Routers, and often have interface Ethernet and Wi-Fi, also functioning as a gateway, switch and wireless access point. Mobile phones as 3 G routers: currently it is possible to get Internet access from an electronic device using mobile phones as routers 3 G, being the only necessary requirement that both teams are capable of communicating among themselves, providing to it several options of connectivity, as data cable, infrared port Infrared Data Association (IRDA), Bluetooth or Wi-Fi.
