WiFi USB dongle (WiFi USB LAN Card) as the WAN for the WiFi Router

What is it? Why should I have a WiFi USB dongle (WiFi USB LAN Card) as the WAN of the Router?

Normally router has the RJ45 ports, there is one marked as WAN. In the router mode, the IP address three octets are different with other LAN devices. Like WAN is 192.168.1.x, LAN is 192.168.111.x. The WAN(RJ45 port) normally is linked with switch or the other router’s LAN port. Our setting is make a WiFi USB dongle linked with WiFi Router’s USB port as a WAN linking. To avoid the radio frequency interference, the channel of the WiFi USB dongle is always different with the WiFi router.

The application is you can use a high gain WiFi USB dongle (AWUHN2405, Top Catcher, Megabond) to get the WiFi internet linking from WISP’s base station far away like 5km. Those dongles can mount in outdoor or on glass to get the signal from outside. The WiFi USB dongle’s USB cable can be 10 or even 20Meters long. The WiFi Router can broadcast the signal easily in the area we want, like dome or inner room.

Before is using a WiFi CPE to get the signal and use the CAT5 cable to link with the WiFi router. Now we replace WiFi CPE with WiFi USB dongle. Not only the cost also the application, could be the repeater easily

What is the difference between real AP Router and Soft AP?

Real AP Router its CPU embedded can do more than WiFi USB dongle soft AP, like SNMP, multi SSID, VPN, multiple VLAN etc..


This is not an USB/ PCIe client in Module, this is a full AP Router full function in a module.

The World First AP Router in the market today. We are expecting many copy cat of this concept.

What advantages for WiFi AP Router Module (Mini PCIe Card)?

  1. Cost Optimized for specific application.
    Save your time cost and development cost.
  2. Flexible for draft design and application.
    You can save your time to design a new communication application in short time like 2 weeks only then finished, easy upgrade, ie. Upgrade from 11b/g/n to 11a/b/g/n, and high power etc..
  3. Time to Market, plug and play.
  4. Software transparency.
  5. Full AP Router Functions / Features.
  6. Easy Upgradable.
  7. Compact Tiny Size.
  8. Easy for Controller design.

Hope everyone like this idea and welcome to ask us more questions!

The Mystery between RF Output Power and EVM (Error Vector Measurement) for WiFi Products

Taipei, Taiwan WiFi products are marked with High power promotion, are they real High Power?

All electronic products’ or devices’ output power are counted by Watt. There are three units seen in WiFi products frequently, dBm, dBi, and EIRP. Regarding dB and Watt conversion table you can link to http://www.asiarf.com/dB-to-Watt-Conversion-Table-support-view-5.html take a look.

Below more detail about these units:

As we know Watt is the electronic power unit.

dBm is an abbreviation for the power ratio in decibels (dB) of the measured power referenced to one milliwatt (mW). Most of vendors mark the highest output power is based on IEEE802.11b mode.

dBi is the forward gain of an antenna compared with the hypothetical isotropic antenna, which uniformly distributes energy in all directions.

EIRP (Equivalent isotropically radiated power) is the sum of output power of WiFi device and transmission loss (cable loss) and antenna’s gain. Normally you will see the amount of EIRP is big number like 10Watts or even more. Donot be scared, go to check and see, you will find out where you need to watch out for the radiation.

There is another important index called EVM (Error Vector Measurement). The lower percentage, the quality of signal transmission is better. Like 3% is better than 5%. If the EVM is higher than 5.5%, then you can see the signal index is good, but transfer the data, no. That means you cannot get homepage from internet either. Most of vendors’ QC index is 5% or 5.5%, some special high quality products is 3%, meanwhile the output power index will be a little lower. For the linking quality is also much better. From now on, if you compare the high power products, you should look at both indexes.

Hope these is helpful for your choice with High Power Products.
