Tutorial: 5G Wireless

One place 5G base stations will be deployed is on streetlights

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’ll be covering 5G on the last day of BOOT CAMP.

“We like to travel”

“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.

Tutorial: SIP Trunking

One of the newest service offerings from carriers is SIP Trunking.

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.

Our Specialty

Our Specialty

Our specialty is explaining telecom technologies to non-engineers who need a comprehensive update and overview, as well as for newcomers who need to get up to speed quickly.
Since 1992, we’ve spent thousands of hours developing and refining extremely valuable telecommunications training, Voice over IP (VoIP) and SIP training, and IP telecom training courses containing knowledge that spans years of university education, hands-on engineering, consulting and interaction with the biggest companies in the business.
We’ve organized and distilled this knowledge into proven training courses that consistently draws rave reviews from people like you – needing to build a solid base of knowledge, understand the jargon and buzzwords, fill in the gaps and understand mainstream technologies and trends… and how it all fits together.
We’ll start at the beginning, cut through the jargon, bust the buzzwords, sort out technologies and provide an understanding of mainstream trends and practical cost-effective solutions… without bogging down on technical details.   more

Best-of-Breed Quality – GSA Contract

Best-of-Breed Quality – GSA Contract

Since the beginning, our objective has been to be “best of breed”, providing the best quality training of this type available… at a lower price point than competitors.
Our success in the drive for quality is proven by follow-on business: often, one person from a company attends a seminar, then others from the same company attend subsequent sessions. In a number of cases, one person has attended a public seminar, then their company has had us in for private onsite training of dozens or hundreds more of their personnel.
We are proud to have been awarded a United States Federal Supply Schedule GSA Contract number GS-02F-0053X, which means pre-approved quality and pricing. Applying for this US Government supply contract and being evaluated for acceptance by the GSA was a two-year-long process with a 200-page offer, which included quality rating where we scored 97%!

Who Should Attend

Who Should Attend

Teracom’s training is geared towards non-engineers who work for:
• Telecom network and service providers including telephone companies, fiber backbone companies, broadband (cable) companies, mobile companies, CLECs and aggregators and resellers,
• Telecom equipment manufacturers including manufacturers of CO equipment, switches and routers, fiber and wireless transmission systems, handsets and last-mile technologies,
• Organizations that buy telecom equipment and services, including banks, power companies, government and military… including the telecom department of Wells Fargo, Entergy, the Justice Department, the US Marines, Oneida Tableware, the SF Giants and Portland Trailblazers amongst many, many others.
… and individuals who would like to improve their skills for this kind of job.
“Non-engineering personnel” means professional personnel:
• whose primary functions include accounting, tax, finance, business development, planning, marketing, sales, operations, telecom help-desk support, telecom service ordering and auditing, and software development,
• who are required to deal with telecommunications network technologies in their job,
• who have not had formal training on the telecom network and its related technical jargon, acronyms, abbreviations and technologies.
• who experiences frustration at not understanding all the technical terms and how everything fits together, has learned bits and pieces on the job, and is at risk of being inefficient or even making errors in their job because of it.
“Training for non-engineers” means that the training is at the concept level, understanding the key ideas and mainstream practices, and don’t get into detailed design discussions. For example, we discuss the ideas behind SIP, what it is and it works, but don’t analyze SIP message packets.
An exception to the “non-engineers” audience is engineers who are not telecom engineers. We have trained many software engineers and developers, who are tasked with developing provisioning, operations or billing systems for telecom services – but who have little or no knowledge of the “network”, and will benefit from understanding the application for the software they are developing. We also see mechanical, chemical and civil engineers who have ended up working for a telecom company and need to fill in gaps.
