Scaling large with small cells

Nagi Mahalingam, MTS at Airvana

A history of standardization efforts within 3gPP, current advancements in small cells and a few practical deployment themes are considered. Small cells are among the most credible solutions for improving spectral efficiency per unit area. The overlaying of small cells alongside a heterogeneous mixture of macro cells and pico cells facilitate greater spectral reuse analogous to cell splitting of macro cells into smaller macro cells. Through ad-hoc deployment of small cells in hotspot areas where demand for greater traffic capacity persists, the operator is able to deliver an increase in capacity precisely where required. Small cells offer a superior option for the operator while keeping capital and operational expenditures manageable.

Nagi Mahalingam received his Ph.D in Biomedical engineering from the Royal Melbourne Institute of Technology, Australia. He has been a member of the Technical staff at Airvana’s Advanced Technology group since June 2008 developing solutions for varied problems in the areas encompassing Self organizing networks and Radio resource management for LTE and WCDMA. Prior to this, Nagi worked with NEC Japan, Nokia Research UK and Motorola UK where he was involved in intellectual property development and standardization efforts for LTE, WCDMA and TETRA within 3GPP / ETSI.

Venue Note: This is our venue at the new Verizon Technology Center Campus in Waltham.

The meeting begins at 7 p.m. at the new meeting auditorium at the Verizon Technology Center. The address is 60 Sylvan Road, Waltham, MA 02451. The entrance is by the far corner – with the picnic tables out front – and not the tower or the new building. It is most easily reached by the West Street entrance.

Important Note: Verizon Technology Center requests the names of the meeting attendees in advance of the meeting. If you plan to attend, please send a note via e-mail with your name to John Nitzke at by Wednesday, April 2nd.

The meeting is preceded by dinner at Bertucci’s, Winter St, Waltham at 5:30 PM. The speaker will be joining us at dinner.

Directions to Bertucci's restaurant in Waltham: Take Exit 27B on I95/128, heading west on Winter Street. After exiting, stay all the way to the right and take the first right turn into the shopping plaza. Please let Bob Malupin know if you plan to attend the dinner at Bertucci’s. Bob can be contacted at .

Directions to Verizon Technology Center (old Verizon Labs location), 60 Sylvan Rd. campus, Waltham, MA 02451: Take Exit 27B on I95/128, heading west on Winter Street. Stay all the way to the right. Verizon Technology Center is 1/2 mile ahead. At the second traffic light, turn left onto WEST ST. and then take the first right (at the Verizon sign) which leads into the Verizon campus. Take the first left. The building and entrance for the meeting are on your right. Note that the entrance to the auditorium area is by the far corner – with the picnic tables out front – and not the tower or the new building.

The Cloud meets Bluetooth Smart

Joe Decuir

Bluetooth Low Energy, aka Bluetooth Smart, can wirelessly connect sensors that run on coin cells or scavenged power for years. That makes Bluetooth Smart attractive for implementing the "Internet of Things". The missing piece: connecting these devices to the Internet. The Bluetooth Special Interest Group has just published a pair of RESTful APIs. These APIs, implemented in a gateway, can allow an Internet client application to find, connect and operate Bluetooth Smart servers: sensors and effectors. The presentation will cover: what is Bluetooth Smart? How does it work? How does the energy get so low? How the client-server architecture works. How to fit a RESTful API to that architecture. Use cases. Perspective with other connectivity methods. For reference: on IEEE Xplore, see articles on Bluetooth Smart in IEEE CES Magazine for January 2014 and April 2014.

Joe Decuir PhotoJoe Decuir was one of the original engineers at Atari, who helped design, build, and produce the Atari 2600. He also wrote the game Video Olympics, a Pong collection that launched with the system. He later went on to help develop the Amiga, many modems (including the first fax modem) and the USB architecture.

Joe is still having an interesting career. Highlights: video game graphics, wired connectivity and wireless connectivity. His day job is to advance wireless connectivity, as a Standards Architect for CSR, as the chairman of the Bluetooth Internet Working Group, and as a Distinguished Lecturer for the IEEE Consumer Electronics Society. For a hobby, he is also vice chair of the IEEE Global Humanitarian Technology Conference for 2014.

Meeting will be held at MIT room E51-345
