Grandstream’s 3 most common analogue to VoIP hybrid deployments.

Grandstream’s 3 most common analogue to VoIP hybrid deployments.

Voice over IP delivers major improvements to traditional communication networks, and as a result legacy analog phone system are on their way out. Ten years ago, 80% of homes had landlines, but today that number is down to 43%— and businesses are following this trend as well. However, much VoIP is becoming the go-to technology for communications, it is important to acknowledge that certain markets cannot fully convert to a total VoIP solution. Not recognizing this could lead to loss in potential sales against competitors. In these situations, a hybrid VoIP network can help deliver the flexibility and power of an IP solution while catering to the restraints of your customer. Below are some of the most common situations and their solutions.   Existing Infrastructure Investment   One of the most common reasons businesses may want to write off VoIP is because of the existing investment in their telephony network. A completely new communications deployment may be something that can scare a company, especially small to medium sized businesses who have limited resources. An easy way to work around this is to construct a hybrid VoIP network that maintains the initial analog investment while taking on the benefits that VoIP and SIP offer. An analog to VoIP gateway can connect to the legacy telephony endpoints, while also connecting to an IP PBX. Seamlessly integrating incoming VoIP trunks and an IP infrastructure with the existing analog devices.   Lack of VoIP Availability   There are various reasons why businesses could lack the capabilities to switch to VoIP entirely. Geographically related bandwidth restraints or legal reasons could prevent businesses and enterprises...
The Fibre of Wireless – introducing you to millimetre wave technology.

The Fibre of Wireless – introducing you to millimetre wave technology.

Millimeter Waves – what you need to know.   Millimeter waves are the part of the spectrum that sits between 30GHz and 300GHz, also known as extremely high frequency (EHF) or very high frequency (VHF). In telecommunications, millimeter waves are used for a variety of services on mobile and wireless networks, as it allows for higher data rates of up to 10 Gbps Full Duplex. The typical millimetre waves that are used in telecommunications currently are V-Band (60GHz) and E-Band (70/80GHz).   Why are MMW’s important?   Millimeter waves are the future. They are the building blocks which entire networks are increasingly starting to rely on, and they are the foundation of the 5th Generation (5G) of mobile networking and Fixed Access. The term fibre-like wireless is used, not lightly, as the throughput capabilities in the millimetre-wave spectrum are absolutely astounding, at up to 10 Gbps! Another reason why they are important is because they allow their users to move away from congested spectrum, and delivery maximum reliable throughput, without the hassle of needing to mitigate interference. That’s right, on Millimetre Wave spectrum, interference is a thing of the past.   Summary   V-Band (60GHz) is a licence-exempt ISM band in South Africa, which means no license costs. E-Band (70/80GHz) is light-licensed, meaning you deploy and register your link within 30 days after deployment, or fully licensed, either of which, will only cost you R 141 per channel per annum. Where E-Band (Siklu / SIAE) is solely used for high capacity Point-to-Point solutions, 60GHz is currently seeing an explosion in short distance, high capacity, last-mile Point-to-Multipoint deployments and solutions...

Last-mile fibre connectivity made easy with PON.

Last-mile fibre connectivity made easy with PON.

As fibre to the home (FTTH) deployments with passive optical networks (PON) continue at an ever-increasing rate, the constant growing demand for internet video streaming has fixed copper and wireless service providers already conducting trials of GPON and EPON, with plans for deployment imminent. PON is the highest speed, longest life, lowest cost, point-to-multipoint network infrastructure available on the market. Offering a genuine future‐proof access network with flexibility and upgrade capability well into the future. This high bandwidth, power saving, green technology is transforming a wide range of businesses and government agencies. Including mining accommodation camps, hotels and multi-dwelling units, campus-style building layouts, retirement villages, residential and commercial developments, corporate and high-rise buildings.   At a recent fibre conference hosted by MyBroadband, SEACOM reiterated that we have a surplus of core fibre and not enough last-mile deployments. This is in due to the fact that wireless compliments our geographic make-up, however in dense suburban areas, where the demands on capacity are more, it is more feasible to deploy a fibre network to offer capacity to numerous subscibers while keeping costs low. This is where PON falls in.   What is PON A passive optical network (PON) is the section of a Layer 2 network that includes everything between two active elements: the headend unit, or optical line terminal (OLT) and the customer premises equipment, or optical network unit/terminal (ONU/ONT). A PON uses optical wavelength-division multiplexing (WDM) so a single fiber can be split to connect multiple ONUs to a single port and can be used for both downstream and upstream traffic to support quad-play services: data, IPTV, voice, and...
