What is 3G?

3G is the third generation of wireless technologies. It comes with enhancements over previous wireless technologies, like high-speed transmission, advanced multimedia access and global roaming. 3G is mostly used with mobile phones and handsets as a means to connect the phone to the Internet or other IP networks in order to make voice and video calls, to download and upload data and to surf the net.

3G has the following enhancements over 2.5G and previous networks:

  • Several times higher data speed;
  • Enhanced audio and video streaming;
  • Video-conferencing support;
  • Web and WAP browsing at higher speeds;
  • IPTV (TV through the Internet) support.

What is ADSL Router?

An ADSL router is also known as a DSL modem. The router connects the computer to the DSL phone line so the ADSL service can be used.

What is 3G Router ?

It is a router take a connection from 3G/CDMA USB based Datacard and share with multiple computers simultaneously with desktop computers as well as wifi based devices.

How does 3G Universal Datacard works ?

It is Datacard user can use any operator 2g/3g SIM card and access internet via pocket/3g data services.

What is the difference between wifi A/B/G/N standard?

For your convenience, the main differences between 802.11b, 802.11g, 802.11a, and 802.11n are summarized below.

Standard Speed† Range† Frequency
802.11b 11 Mbps 150 Feet 2.4 GHz
802.11g 54 Mbps 50 Feet 2.4 GHz
802.11a* 54 Mbps 50 Feet 5 GHz
802.11n 300 Mbps 450 Mbps§ 175 Feet 2.4/5 GHz

† Real-world speeds are more modest. Likewise, range varies depending on configuration and placement.

What is the Differnce between GSM and CDMA ?

GSM and CDMA are competing wireless technologies with GSM enjoying about an 82% market share globally. CDMA is the more dominant standard. Technically GSM (Global System for Mobile communications, originally from Groupe Spécial Mobile) is a specification of an entire wireless network infrastructure, while CDMA relates only to the air interface — the radio portion of the technology.

Code division multiple access (CDMA) describes a communication channel access principle that employs spread-spectrum technology and a special coding scheme (where each transmitter is assigned a code). CDMA also refers to digital cellular telephony systems that use this multiple access scheme, as pioneered by QUALCOMM, and W-CDMA by the International Telecommunication Union (ITU), which is used in GSM's UMTS.

What is Security Algorithm DISABLE, OPENWEP, SHAREDWEP, WEPAUTO, WPA, WPA-PSK, WPA2, WPA2-PSK, WPAPSKWPA2PSK, WPA1WPA2, 802.1X ?

Disable: direct connection without authentication.

OPENWEP: a handshake method of WEP encryption which encrypts through the WEP key.

SHAREDWEP: another handshake method of WEP encryption which also encrypts through the WEP key and its encryption type is the same as that of the Open Mode.

WEPAUTO: it can automatically select Open Mode or Shared Mode and its encryption type is the same as the first two.

WPA: WPA that is authenticated by RADIUS server.

WPA-PSK: (WPA Personal) Wi-Fi Protected Access with the pre-shared key (WPA is a solution to improve the safety of interoperable WLAN based on the standard, which could greatly enhance data protection and access control level of the wireless LAN system.).

WPA2: WPA2 that is authenticated by RADIUS server.

WPA2-PSK: (WPA2 Personal) WPA2 with the pre-shared key, which can provide better safety than WEP or WPA.

WPAPSKWPA2PSK: WPAPSKWPA2PSK is WPA-PSK and WPA2-PSK mixed mode.

WPA1WPA2: WPA1WPA2 is WPA1 and WPA2 mixed mode.

802.1X: This security mode is used when a RADIUS server is connected to the Router. 802.1x, a kind of Port-based authentication protocol, is an authentication type and strategy for users. The port can be either a physic port or logic port (such as VLAN). For wireless LAN users, a port is just a channel. The final purpose of 802.11x authentication is to check if the port can be used. If the port is authenticated successfully, you can open this port which allows all the messages to pass. If the port isn't authenticated successfully, you can keep this port "disable" which just allows 802.1x authentication protocol message to pass.

When using OPENWEP, SHAREDWEP, WEPAUTO authentication, it is required to set the key: this router can be filled in 4 at most (ASCII or 16 hexadecimal with a length of 10-26) keys. Users can select one key as the current valid key (default key) from four groups of the pre-set keys.

When using WPA-PSK, WPA2-PSK or WPAPSKWPA2PSK authentication, it is required to fill the information as follows:

WPA Algorithms: users can select AES (Advanced Encryption Standard) mode, TKIP (Time Key Integrity Protocol) mode or a mixed-mode of the first two.

Pass Phrase: the password used by WPA (8-63 characters in ASCII code)

Key Renewal Interval: to generate a valid date for the key that you set.

When using WPA,WPA2 or WPA1WPA2 authentication, it is required to fill the information in RADIUS server as follows: IP (IP address of RADIUS), port (monitoring port of RADIUS) and the shared key (the authentication key of RADIUS server).

Policy: 'Allow' means only allowing client ports with specific MAC address to be connected while 'Reject' means only banning client ports with specific MAC address to be connected. 'Disable' means all client ports can be connected.

Why My Modem Not Getting Good Speed?

The reason behind speed issue because of the poor signal or plans or the modem issue also. So please consult the operator.

I'M Getting in good speed in Bangalore in my native not cross 100kbps why?

Because the issue is your area doesn't have highspeed data service provided it's still in lower bandwith in rural.
