IEEE wireless standards
The IEEE 802.11 wireless Ethernet standards come from the Institute of Electrical and Electronics Engineers, Inc. (IEEE). This organization only sets the specifications for the standards—it doesn’t test individual wireless products for compliance to these standards. Because the IEEE 802.11 standards are real Ethernet standards that look like Ethernet to your applications, compatibility with wired […]
Applications driving demand for next-gen PON
Four major application areas are driving next-gen PON development and standardization. FTTBuilding for multi-dwelling units (MDUs) – In these deployments, next-gen PON would provide more bandwidth to be shared among the units in the building. Enterprises – Next-gen PON would provide enterprises with more upstream bandwidth, supporting video conferencing and cloud-based file backup, […]
The advantage of TWDM PON
With the completion of lab trials this year, commercial trials expected in 2015, and initial deployments forecast for 2016, TWDM PON (time wavelength division multiplexing passive optical networking) is on the horizon. While today’s PON meets the requirements of residential subscribers, small-tomedium-sized usinesses (SMBs), and some MBH (mobile backhaul) applications, CSPs (communications service providers) want […]
What is VSAT
VSAT is short for very small aperture terminal, an earthbound station used in satellite communications of data, voice and video signals, excluding broadcast television. A VSAT consists of two parts, a transceiver that is placed outdoors in direct line of sight to the satellite and a device that is placed indoors to interface the transceiver […]
What is Quantum Teleportation?
I. INTRODUCTION Teleportation is commonly understood as a fictional method for disembodied transport: An object or person is disintegrated at one place and it is perfectly reconstructed somewhere else. Thus, teleportation can be compared to transmission of a three-dimensional object using a kind of super fax machine which, however, destroys the original object on scanning. […]
Network testing: 5 tips for beginners
Regular network testing is a critical element of maintaining a well-performing system, identifying potential problems before they cause serious malfunctions, and preparing for future improvements to keep up with changing technology. Embarking on this adventure should not be taken lightly, and that means the first step for beginners is to have a plan of attack. […]
IoT Needs OSP
Ubiquitous connectivity, to anything, anywhere, and at any time. That is the promise of the Internet of things (IoT) and we’re all aware that it will enable tremendous changes to the way people live. Outside plant (OSP) usually gets left out of any mention alongside this topic. However, OSP plays a crucial role in providing […]
What is return loss for fiber optics
The return loss RL is a measure of the portion of light that is reflected back to the source at the junction. It is expressed in decibel. The higher the RL value in decibels, the lower are the reflections. Typical RL values lie between 35 and 50 dB for PC, 60 to 90 dB for APC and […]
LTE and WiMAX comparison
Comparison of LTE Rel-8 and WiMAX 802.16e There are a lot of commonalities between LTE Rel-8 and WiMAX, but there are some notable differences. For example: LTE uses SC-FDMA for the uplink, whereas mobile WiMAX uses OFDMA. LTE user equipment (SC-FDMA) has a lower peak-to-average-power ratio when compared to mobile WiMAX user equipment (OFDMA), […]
