- Operators will initially deploy small cell equipment as in fills on the pico and microcell layers, but will quickly transition to deploying them as a fundamental part of a network rollout.
- The number of LTE small cells sold (127,000) will surpass the number of LTE macrocells, forecast at 113,000, as early as 2014.
- Semiconductor suppliers are positioning themselves to participate in this market with TI, Freescale, Cavium, Mindspeed, and DesignArt among the manufacturers offering new “base station-on-a-chip” SoCs.
- However, LTE base station revenues will continue to be dominated by macro base station revenue with small cell revenue of $1.09 billion representing only 5.2% of the total revenue of $20.86 billion in 2014 and growing to $4.44 billion or 23.9% of the total $18.60 billion LTE base station market by 2016.
- Equipment manufacturers have been quick to respond to this shift in RAN (Radio Access Network) architecture. Ericsson acquired BelAir networks as part of its “HetNet” initiative, Nokia Siemens Networks announced Flexi Zone, Alcatel-Lucent continues to expand its lightRadio™ portfolio and Huawei has announced its AtomCell products.

- 3 hour ride so we leave early.
- Get to the school and find the admissions office.
- Admissions office staff tells us about our appointment with the Mechanical Engineering Department Chair. We get the name and “office” location of the chair and head over to the Engineering building.
- We get over to the Engineering building and find out the “office” is actually a small conference room.
- There are two other families with us. Two of the potential students are female and one is male.
- The department chair (at least I think he was the department chair but not 100% sure) shows up.
- The professor/chair spends 15-20 minutes talking about himself. The awards he has received, the grants he has. When he found out we were from Massachusetts of course he just had to tell us about all the time he had spent and great work he had done at MIT.
- So far, just a waste of everyone’s time. No real damage.... yet.
- It gets bad though when someone breaks in with a question.
- One of the parents asks about curriculum. He goes into a diatribe about how he is teaching the same courses as MIT using the “big thick classic books”. He mentions ABET but does not describe what it is or means. Other families are so lost.
- He then stressed over and over again about how much time students have to spend reading these classic textbooks each week. He indicated with his fingers (about an inch) saying “this thick” for each class. He says "this thick" and indicating with his fingers at least 10 times. Each time he does it is with a scowl on his face.
- He then tells us the problem with American students is "you are lazy" and “you will likely fail”. This time with a look of disgust on his face.
- “You will have at the most 4 hours per week of free time. You can use this time to go to the mall (and that is a "waste of time") or to do your laundry. You will have no other free time and must constantly study those classic textbooks reading "this thick every week.”
- Then we got more of the lazy American student language.
- At this point I cut it off and told him we had another appointment and had to leave. The other two families got up and followed us as quickly as they could out the door.
- I did tell them don't listen to that guy.
- 3 hour plus ride home with traffic. What a wasted day.
Again, no names here. I am sending a link to this post though to the admissions director at that school.
The Dean of the Engineering school called late this afternoon and we talked for a long time. Good honest discussion and he is going to be sure this does not happen again. I was impressed with his understanding and dedication to the program and especially the students.

Timing is critical here (that's why it's called synchronous) for communications across the entire network.

Back from vacation today and my wife did a software upgrade to iOS 5.1 on her AT&T Wireless service iPhone 4S. Sure enough her indicator now reads "4G" (upper left hand corner) and she's getting some pretty nice bandwidth. Here's a screen shot after running the speedtest.net app.
As a comparison, here's the same test run on my AT&T 3GS iphone.
I'm also updated to iOS 5.1 but no "4G" for me on my older phone.
Is it really "4G" on her phone? Well - no. It's running a 3G service called HSPA+ (sort of 3G on steroids - up to 56 Mbit/s downstream and 22 Mbit/s upstream) which AT&T is using to get over the bandwidth hump until LTE rolls out. I've written about 4G services fairly extensively - follow this link to read my older posts.
Regardless, that's some sweet bandwidth. If you've got an iPhone 4GS running on the AT&T network, be sure you're up to date on upgrades. As for me and my almost 3 year old 3GS - I'm stuck in the "3G" world until I upgrade my phone. The 3GS does not have a HSPA+ radio in it.
How can you check which iOS version you are running on your iPhone? On your phone select "Settings", "General" and then "Software Update". You should see a screen like the screen shot from my 3GS below.
If you are not up to date follow the instructions on the Apple website.

In the United States T-1 carriers have been replaced in many locations with Synchronous Optical Network (SONET) systems. Internationally, the SONET equivalent is called Synchronous Digital Hierarchy (SDH). Both SONET and SDH systems consist of rings of fiber capable of carrying very high bit rates over long distances. Copper has been replaced by fiber to inter-connect most Central Offices (CO’s) in the United States at bit rates ranging from the SONET base rate of 51.84 Mbps up to 39,813,120 Gbps.

In January for the past few years, our NSF funded National Center for Information and Communications Technologies has been co-sponsoring a Winter 2012 ICT Educator's Conference in San Francisco in collaboration with the Mid-Pacific Information and Communications Technologies Center.
This year the conference was held at the Microsoft offices in downtown San Francisco and we were fortunate to have Facebook's Director of IT Operations, Steven Ruggiero as one of the keynotes. Heres his presentation - it's really good.
Thinking about a technical career or know someone who is? Good stuff for students, parents, educators, guidance counselors, etc.
