12. What is a bridge (AccessPoint)?

AccessPoint, generally known as a network bridge, as the name implies, is deemed to be traditional wired LAN and wireless local area network of bridges, so any computer equipped with a wireless network card of the PC can share via the AP to even wired local area network, wide area network resources. In addition, the AP itself also has a network of capabilities for wireless network cards with the PC mutatis mutandis, of the control.

13.AccessPoint use how many workstations simultaneously support?

Theoretically you can support a CLASSC, but in order to enable the workstation itself have sufficient bandwidth available to the general recommendations supported one AP about 20 ~ 30 meters of the station for the best.

14. What is the roaming (Roaming)?

As mobile phone, you can roam in different base stations, wireless network workstation can roam between different AP, AP group defines the same ESSID, natural wireless network workstation free roaming in radio waves can cover the area.

15. If the wireless network equipment set up on the outdoor, how to protect against lightning?

Basically, the wireless network you can configure the arrester equipment, this device you can choose to install a wireless network device in order to facilitate foreign of surge caused damage to the system.

16. What is the AccessControl?

Basically every wireless network card has a unique hardware address, the so-called MACaddress, you can define certain card AccessControltable can login to the AP, some card is denied access, so they can achieve control mechanism that prevents non-associated persons feel free to log into the network, the theft of resources.

17. What is ASBF?

ASBF (AutomaticScaleBackFunctionality), this feature is specific to the function, GemplexAP guarantee WLAN is always the best quality online, and provide support for multiple manufacturers of wireless network card, but its network card must be compatible with the specification and design of the IEEE802.11.

18. What is a PowerManagement?

Because the Notebook uses about 2 hours or so after they must charge, if and while using the other peripheral device, you must have more power, so this feature is to effectively manage a wireless network card's power consumption, in other words, its timely control when DATAsendingorreceiving, is in the "Wakeupstatus", while in powerdownmode.

19. antenna using the length of the feeder are influential transmission quality?

In General, the use of antenna-feeder length, material quality, impedance matching, will have some of the signals, but the most obvious is to gain attenuation. Usually in terms of length 20feet or signal attenuation about 1.2dBi about average attenuation 8dBi will let the original transmission distance of approximately halved, so the length of the feeder and quality in wireless products application cannot be ignored.

20. What is Ad-hoc?

Constitute a special wireless network application mode, a group of computers connected to the wireless network card to connect, share, through the AccessPoint.

21. What is Infrastructure?

An integrated wired and wireless local area network infrastructure, and through this kind of schema mode, you can reach the shared network resource, the application needs through the AccessPoint.

22. What is the BSS?

A special application called Ad-hocLAN BasicServiceSet (BSS), a group of computers to set the same BSS name, you can become a group name, and this BSS, the so-called BSSID.

23. What is ESS?

An Infrastructure applications, one or more of the above, the BSS is defined as a ExtendedServiceSet (ESS), users can access on roaming and the ESS BSSs any information in which you must set the same AccessPoints ESSID and channel to allow roaming.

24. What is SNMP?

"SimpleNetworkManagementProtocol", a network of communication protocols through SNMP software can be connected to an SNMP-enabled devices and gathers all the information of the device and do other integrated applications, there are support GemplexWirelessLANproduct.

25. What is a WEP?

"WiredEquivalentProtection" shorthand, a data encryption, the encryption is WEP40bits IEEE802.11 standard specification. Processing through WEP can make our information more secure in the transmission.
