Wireless Router

Wireless router is very important for personal network living.

From technology, Wireless router is mainly classified in wireless wifi router, wireless wimax router, and wireless cell router.

From used filed, wireless router is classified soho (also called in non-industrial) class, and industrial class for Industrial Ethernet Router.

SOHO is for large data use, for example 3G router (including EVDO Router, HSDPA Router, and HSUPA Router, and HSPA Router.)

A wireless router is a device that performs the functions of a router but also includes the functions of a wireless access point and a network switch. They are commonly used to allow access to the Internet or a computer network without the need for a cabled connection. It can function in a wired LAN (local area network), a wireless only LAN (WLAN), or a mixed wired/wireless network. Most current wireless routers have the following characteristics:

1. LAN RJ45 ports, normally 1 or 2 or 4 ports, which function in the same manner as the ports of a network switch

2.      A WAN port, normally 1 RJ45 port to connect to a wide area network, typically one with Internet access. External destinations are accessed using this port. If it is not used, many functions of the router will be bypassed.

3.      Wireless antennae. These allow connections from other wireless devices (NICs (network interface cards), wireless repeaters, wireless access points, and wireless bridges, for example), usually using the Wi-Fi standard.

4.      Some wireless routers also include a DSL or cable modem in addition to their other components.

As for the wireless antenna, contains GSM/3G cellular antenna and WiFi/Wimax antenna, with different connecting type, such as SMA. Normally antenna is default packed by manufacturer. High gain antenna is available for replacement to receive better and stronger signal so as to get good receiving and transmission of data.

Cellular Router and Modem Difference

Cellular Router
A cellular router short for cell router, is a router provides shared Internet access by incorporating a cellular data modem and providing common interfaces like Ethernet and WiFi. Different cellular routers work on different networks.
Cellular network are divided into GSM cellular, CDMA cellular and 3G cellular, meanwhile, there are GSM router, CDMA Router and 3G Router.
They can be deployed as a primary WAN link to a location where wired connections are not cost-effective, can also be used as a secondary or business continuity plan should the primary cabled link fail, or can be used in moving vehicles to provide Internet access while in motion. Cellular routers range from simple SOHO network oriented devices through rugged industrial units with advanced features.
For SOHO and high data requirement, 3G Router are the best to use. For small data package transmission, GSM router and CDMA router are enough.
EVDO Router, HSDPA Router, HSUPA Router and HSPA Router are hot used in many different areas such as coffee shop, small shop, home, airport, etc.

Cellular Modem
A cellular modem is a modem provides internet access by the cellular networks on GPRS/EDGE/HSDPA/HSUPA/HSPA or CDMA/EVDO networks.
Cellular modem provides a USB port or RS232 port. USB port is for high speed data transmission. RS232 port normally is for industrial application for SMS and small package data transmission.
Router support route features, we can think it built-in modem. Modem is a simple dialing device.
Cellular Router contains Industrial Ethernet Router and SOHO Router.
Cellular Modem contains Industrial Modem and SOHO Modem.

A Typical Question for Cell Router

We often meet cell router users to ask such questions.

Someone asks “How do set up a Wifi router when the main computer uses a router to get the internet?”

It’s a typical question while using the cell router, especially an Industrial Ethernet Router.

The popular cell router is 3g hspa router with maximum 14.4Mbps download speed or even higher.

Details is as follows:
My computer has a router to connect it to the internet. Well I bought a Wifi router so that I could share the connection but I don’t know how to set it up.

Answer 1: We can draw a map like:

Router —> Wifi Router ——> Wired/wireless computers.

You need to attach the router cable with the WAN side of wifi router and then attach all your computers with the Wifi router either through a cable or wirelessly.

Answer 2: Are you using a “router” that plugs directly into your computer rather than a separate box that is wired in? I have a friend who used one of those and tried to use that computer as a router / gateway using the cell card / router in that machine. In short, it didn’t work.
You can buy a special router that accepts cell based router cards that then act as a normal wired router so you can connect other wireless routers (some may have a built in wireless so you don’t have to get a separate one) and/or other computers to it.
