PPP Over Ethernet (PPPoE)

Education, Networking, Tutorial
Modern access technologies are faced with several conflicting goals. It is desirable to connect multiple hosts at a remote site through the same customer premise access device. It is also a goal to provide access control and billing functionality in a manner similar to dial-up services using PPP. In many access technologies, the most cost effective method to attach multiple hosts to the customer premise access device, is via Ethernet. In addition, it is desirable to keep the cost of this device as low as possible while requiring little or no configuration. PPP over Ethernet (PPPoE) provides the ability to connect a network of hosts over a simple bridging access device to a remote Access Concentrator. With this model, each host utilizes it's own PPP stack and the user is…

Characteristics of TDMA (TIME DIVISION MULTIPLE ACCESS)

Education, Networking
Characteristics of TDMA: Shares single carrier frequency with multiple users. Non-continuous transmission makes handoff simpler. Slots can be assigned on demand in dynamic TDMA. Less stringent power control than CDMA due to reduced intra cell interference. Higher synchronization overhead than CDMA. Advanced equalization may be necessary for high data rates if the channel is “frequency selective” and creates Intersymbol interference. Cell breathing (borrowing resources from adjacent cells) is more complicated than in CDMA Frequency/slot allocation complexity. Pulsating power envelope: interference with other devices.

What is Time Division Multiple Access?

Education, Electronics, Networking, Tutorial
Time division multiple access (TDMA) is a channel access method for shared medium networks. It allows several users to share the same frequency channel by dividing the signal into different time slots. The users transmit in rapid succession, one after the other, each using its own time slot. This allows multiple stations to share the same transmission medium (e.g. radio frequency channel) while using only a part of its channel capacity. TDMA is used in the digital 2G cellular systems such as Global System for Mobile Communications (GSM), IS-136, Personal Digital Cellular (PDC) and iDEN, and in the Digital Enhanced Cordless Telecommunications (DECT) standard for portable phones. It is also used extensively in satellite systems, combat-net radio systems, and PON networks for upstream traffic from premises to the operator. TDMA is…
