Wireless Broadband Connection

Teletronics' point-to-point system first connects the customer's network by a cable and a connector, and proceeds with a trial, calibration, and proven connectivitiy, before it is turned over to the customer for operation. Using multiple systems, customers can connect more that two locations to form an expanded network. After the first links are established by Teletronics, including trials, demonstrations and the training of customer staffs, the customer can take over the subsequent installations and start operation.

Point to Point

Teletronics' point-to-multipoint system takes advantage of the IP backbone network. It enables a cumulative data rate of up to 4 Mbps from the centralized hub unit and can support hundreds of customer's sites within the network. The distance from the centrazlized hub to the customer sites can vary from a frew meters to tens of kilometers, and the antenna coverage patterns can be uniquely designed to cover either a wide area or a narrow strip as long as line-of-sight paths are available.

Point to Multi-Point

Teletronics' Special Frequency Systems are most popular in the 2.4/5.8 GHz band as the existing 2.4 GHz systems are jammed with interference. Teletronics' Special Frequency Systems are being implemented internationally, with leading customers located in Israel, Canda, UAE, Pakistan, Indonesia, Bangladesh, and many Central and South American Countries.

Special Frequency Systems

Teletronics' Broadband-in-Building system usesits Mini RAS, IPAM, and ATu-R to supply wireline/wireless IP network for multiple tennantsin a building. The Mini RAS, which uses L2TP Technology, under patent pending by Teletronics, assures end-to-end VPN connectivity through PPPoE mode. It is IP based broadband which eliminates the use of ATM connection altogether. The ethernet CAT-5 wiring in building can be eliminated and usage of telephone line wiring will be sufficient.

Voice Over IP (VoIP) Technology

Session Initialization Protocol (SIP)

What is SIP?

Session Initiation Protocol (SIP) is the Internet Engineering Task Force’s (IETF’s) standard for multimedia conferencing over IP. SIP is an ASCII-based, application-layer control protocol (defined in RFC2543/RFC3261) that can be used to establish, maintain, and terminate calls between two or more end points.

Components of SIP?

SIP is a peer-to-peer protocol. The peers in a session are called User Agents (UAs). A user agent can function in one of the following roles:

• User agent client (UAC)—A client application that initiates the SIP request.

• User agent server (UAS)—A server application that contacts the user when a SIP request is received and that returns a response on behalf of the user. .
