Internet Access

A suitable internet access with enough bandwidth and proper settings ensures you a good video conferencing experience. The following are the four most common ways of internet access today.

ADSL (Asynchronous Digital Subscriber Line)

ADSL enables faster data transmission than conventional dial-up modem by utilizing frequencies that are not used by telephone calls over traditional telephone network. The telephone line generally terminates at a digital subscriber line access multiplexer (DSLAM) in telecommunications company (Telco) where data packets are filtered and forwarded to IP network. However, ADSL provides much faster download (512 Kbps to 6 Mbps) than upload speeds (64 Kbps to 1.54 Mbps) which might sometimes cause asynchronous delay in streaming incoming and outgoing videos.

PPPoE (Point-to-point over Ethernet) is a protocol widely used by ISPs to provide authentication, encryption and compression for digital subscriber line (DSL), cable modem etc. End users can enter their specific username and password provided by ISPs to access internet service on PCs or AVer's video conferencing systems.

Dial-up Internet Service

Dial-up Internet runs over the traditional telephone lines, officially called Public Switch Telephone Network (PSTN), to establish a dialed connection to an internet service provider (ISP) such as CHT HiNet. The computer uses a modem to encode and decode IP packets and control information into and from analog signals. This modem occupies the telephone line making it unable to use telephone or fax machine when it is connected. Dial-up service is relatively slow (at a maximum of 56 kbps) and thus unsuitable for video conferencing.

Leased Line

A leased line provides a private dedicated circuit with guaranteed symmetrical bandwidth (T1: 1.544 Mbps, E1: 2.048 Mbps, T3: 45 Mbps, STM-1: 155 Mbps) for data transmission between two or more locations at a fixed monthly rate. It is typically used by businesses to connect geographically distant offices. This service is stable and always active, thus cost-effective for high-volume communications customers.

Leased lines are usually implemented by FTTx (Fiber to the x), which permits high-speed and long-distance data transmission with low attenuation and interference.

Mobile 3G/4G

3G, abbreviation of third generation, is a set of standards and technologies specified by International Telecommunication Union (ITU) for mobile devices to access wireless internet service. 4G, the fourth generation of mobile telecommunications technology, provides broader bandwidth succeeding 3G.

Their applications include web access, mobile TV, video calls and conferencing etc. AVer's mobile solution – EZMeetup software – are designed for PCs, laptops, tablets and mobile phones to connect with our EVC300/ 900 multipoint video conferencing systems.
