New FCC Rulemaking Promotes 700 MHz Band Operations

Posted: 27 Mar 2012 07:33 AM PDT

The Federal Communications Commission (FCC) today acted (WT Docket No. 12-69) to examine the wireless system interference concerns should the Lower 700 MHz band utilize a single band class for devices operating across the Lower 700 MHz A, B, and C Blocks.

In its NPRM, the FCC seeks comment on technical and operational factors as they may impact customers of Lower 700 MHz B and C Block licensees.  The FCC has focused on two interference concerns that may result from use of a single band class: (1) reverse intermodulation interference from adjacent DTV Channel 51 operations; and (2) blocking interference from next door high-powered operations in the Lower 700 MHz E Block.  The FCC requests commenters  to submit measurements and quantitative analyses defining the magnitude and extent of adjacent Channel 51 and Lower 700 MHz E Block interference risks, the availability of effective measures to mitigate interference, relative performance of single band class devises, and costs to the wireless industry in implementing interoperability.

The FCC also wishes to explore possible next steps to take to promote interoperability in the Lower 700 MHz band should it find harmful interference is minimal, or can be readily mitigated.  The FCC NPRM sets out various options to help achieve the ultimate goal of interoperability.

Free Webinar: How to Prevent In-house Wireless from Hitting a Wall

Posted: 23 Mar 2012 06:36 AM PDT

Distributed Antenna Systems, or DAS, is a small-cell wireless application that improves a wireless network and can also cause interference problems. DAS deployments have important implications for building owners, as well as for wireless carriers. It is swiftly becoming a major topic of engineering discussions as a practical solution to 3G, LTE, and 4G network penetration.

Here's your chance to be a part of the discussion! WCAI International is sponsoring a free webinar on the DAS on Thursday, March 29, at 4 p.m. Register HERE.

Addressing the issue will be David Saab, vice president for development at Selective Site Consultants. The Overland Park, Kan., consulting company is a leading provider of services to telecommunications, development, and construction industries. LBA Group Inc. chief technical officer Chris Horne will introduce the speaker and moderate the follow-up discussion.

 

DAS systems solve in-building wireless coverage problems

 

“Site development" is the industry term for the disciplines needed to build wireless infrastructure. Today's wireless world began with a handful of towers and rooftops and exploded with the success of the cell phone. Voice begat data, data begat broadband, and the more people who used it, the more site development activities unfolded.

But the wireless boom revealed the limitations of tower or "macro" sites. The physics of radio waves and propagation through certain building materials—along with the sheer concentration of users—are overwhelming wireless networks. This has led to the development of in-building and other Distributed Antenna Systems.

DAS is deployed inside a structure as well as in limited geographical areas, such as shopping districts and parking lots. But DAS cannot be as straightforwardly deployed as the traditional tower or rooftop systems. Walls get in the way and so do other RF emissions. Limitations on space, safety, and interoperability mean carriers must work together to create networks that provide effective mobile end-user experiences.

The problem is a small in scope but big in implications, and you can learn more about it in the webinar.

LBA provides top-down review and evaluation of DAS and small cell requirements. We specialize in relating enterprise wireless coverage needs to available technologies to aid management decision making and implementation budgeting and control.

The 3G Main Concept – Technical Analysis and Evaluation Procedure

The 3G Main Concept – Technical Analysis and Evaluation Procedure
I.        The required access technology in compliance with the existing regulation and market trend in the Philippines must be the initial consideration for a 3G network nationwide rollout plan.
a.       WCDMA is the major wireless access technology currently deployed by major players in the mobile telecommunication business.
b.      Since Philippines follow the European standard on mobile communication, it is only accurate to follow the same as new entrant in the industry. UMTS is the major standard for 3G deployed here.
c.       3G UMTS Handsets are already flooded the market with different innovations and new functionalities that affect the lifestyle of every Filipinos.
II.      The issuance of Spectrum from the Regulatory Agency
a.       The National Telecommunications Commission (NTC) is the government regulatory agency empowered to facilitate the issuance of 3G license in the Philippines.
b.      Currently we have three (3) 3G licensee in the Philippines; the 4th 3G license was surrendered to NTC for merit to allow the merger of two (2) mobile telecom operator.
c.       Currently we have two (2) available 3G license with a BW of 10MHz each.
d.      The NTC provides additional procedure to smoothly facilitate the issuance of the 3G license to any competent applicant.
III.    The mobile telecommunications market in the Philippines still has room for new players.
a.       The penetration rate of mobile users in the Philippines is high compared to fixed lines.
b.      The merger of the two giant mobile telecommunications operator concludes a dominant position in the market.
c.       With the current population of the Philippines compared to the number of existing subscribers of mobile telecommunications services shows as evidence that new players have chance to get a chunk of the market.
d.      Marketing of innovative services and low cost bundling will be the main attraction for prospect subscribers.

The 3G Technical Concept – UMTS Network – Release 7
I.        Technical Parameters of Release 7
a.       Easier to deploy and LTE Readiness setup.
b.      IMS Platform – a future proof Core Network Setup.
c.       Base station is strategically located due to upgrade of RF Modules which is in conformity with IMT 2000 vision of single RAN capability.
