Get the new CEHv10 credential in-person or online live April 9-13 with EC-Council Master Instructor Kevin Cardwell for under $2000!
I’ve got the DVDs series and would like to express my opinion.
The instructor explains the telecommunication in vertical and horizontal.
Vertically by explaining every subject from its simplest form to its most complex form as a result of developments.
Horizontally by explaining its historical changes as time went by, stage by stage.
The last result is a telecom magical encyclopedia include every aspect in plain language.
I would like to express my extreme recommendation for everyone involve in telecom regardless his position plus whose plan to get telecom service in business or home.

Now that 4G cellular mobile is settled, talk is now turning to 5G.
The first thing to know about 5G is that there are currently no standards, no detailed agreement on what exactly it will be. But we have a number of general indicators to guide the discussion:
1. 5G will employ radio frequencies well above what is currently used for cellular.
The current frequency bands for 3G/4G cellular top out at about 2.6 GHz. Proposals for frequency bands for 5G include “millimeter wave” bands, that is, wavelengths varying between 1 and 10 mm, which correspond to frequencies between about 30 and 300 GHz. No doubt, in the future, there will be unified 5G systems with variations operating in all frequency bands; but the current emphasis is on new technology in the millimeter wave bands.
2. 5G will provide very high bit rates.
With carrier frequencies at 30 GHz and above, very wide frequency bands around those center frequencies can be employed, allowing the radio frequency modems to achieve high numbers of bits per second. In addition, Multiple-Input, Multiple-Output (MIMO) designs can implement massive parallel communications, radically increasing the capacity available to a user. Initial designs and trials have measured 5 Gb/s (5,000 Mb/s). No doubt, this will be pushed beyond 10 Gb/s.
3. Initially, 5G will not be a replacement for 4G.
At millimeter wave frequencies, in-building penetration and refraction around obstacles is poor, and the atmosphere attenuates (diminishes) the signal to the point that line-of-sight between the antennas is necessary, and useful transmission range is measured in the hundreds of meters (yards). This means that the first deployments of 5G will be in environments where base stations can be closely spaced.
One application for all this bandwidth is traffic control: going beyond today’s standalone self-driving vehicles to vehicles communicating with each other and with traffic control systems, with base stations deployed on street lights as suggested by the picture.

“We like to travel”
— seminar attendee during coffee break at a seminar
This reminded us that for many people with good jobs, training is part of the job – including traveling for it… and some people appreciate taking courses in interesting places so they can stay an extra day for a side trip.
In that spirit, here are a couple of outstanding free places to visit close to the Santa Clara BOOT CAMP in March:
1. Pescadero Beach. google maps
Just over the mountains that separate Silicon Valley from the Pacific Ocean is Pescadero Beach State Park and the Northern California coastline. The best part are the tide pools full of interesting things like anemones.
Like many, many other pieces of jargon in the business, many people would like to understand just what exactly it is.
SIP is an acronym for Session Initiation Protocol. This is a standards-based method of setting up Voice over IP telephone calls.
A key thing to know about Voice over IP phone calls is that once the call is set up and two people are talking, their telephones exchange IP packets with digitized speech in them directly.
One person’s telephone creates an IP packet and puts the IP address of the other person’s telephone in the destination address field. This packet is forwarded by routers directly to the other person’s phone.
To be able to do this, it is necessary to know what the other person’s IP address is!
This is the main function performed by SIP: it is an assistant to enable a caller to find out the IP address of the called party’s telephone, so they can send packets with digitized speech to that person’s phone.
Trunking is a term that has been generally used in the telecom business in the past to mean communication between telephone switches. Trunks connect CO switches, toll centers and other switches in the PSTN.
PBX trunks connect an organization’s private switch to a CO switch.
SIP Trunking is a term invented by the marketing department to mean to mean “native communication of SIP call setup messages and Voice over IP traffic between an organization’s locations, with a Service Level Agreement and transmission characteristics sufficient to guarantee the sound quality.” And a gateway service thrown in.
Native means carrying the IP packets without converting them to an old-fashioned telephone call. The IP packets in question are at first carrying SIP call setup messages, then once the call is set up, the IP packets each contain typically 20 ms of digitized speech.
SIP Trunking replaces the previous architecture of PBX trunks.
It would be more accurate to refer to this new service as “SIP and Voice over IP Trunking” – but “SIP Trunking” rolls off the tongue better…
To learn more, attend BOOT CAMP March 27-31, or just the last two days of BOOT CAMP, which are Course 130 Understanding Voice over IP March 30-31.
