Do not neglect to do good and to share what you have, for such sacrifices are pleasing to God.
By sharing their home and food, it was the couple’s way of sharing God’s care with someone. I have put it all at your feet, I trust you with my possessions, with my life, with the kingdom and with my people.

Sascha spoke about “The Culture of Sharing” at the inaugural Ignite Event here in Taipei, Taiwan.
The evening boasted 11 speaker who spoke on a variety of topics from Spontenaety to Bean Sprouts but our own Sascha Pallenberg tackled one of his favorite topics: The Culture of Sharing.
Two months ago, the President’s Council of Advisors on Science and Technology (PCAST) unveiled a bold plan to share 1,000MHz of federal spectrum with cellular providers.
But the Federal Communications Commission has decided to adopt the plan, or at least its first steps. The brief announcement actually doesn’t mention the word "sharing." Perhaps the FCC is trying to avoid controversy. PCAST is chaired by Mark Gorenberg of Hummer Winblad Venture Partners and includes people like Microsoft Chief Research Officer Craig Mundie and Google Executive Chairman Eric Schmidt. In a response to the July PCAST report, the CTIA Wireless Association issued some muted criticism, saying "the gold standard for deployment of ubiquitous mobile broadband networks remains cleared spectrum." We contacted the CTIA yesterday about the FCC proposal in the 3550-3650 band, and haven’t heard back. PCAST doesn't suggest ending the practice of clearing and reallocation of spectrum, but it does think that approach won't be enough to handle growing wireless needs.
The fact that the FCC jumped on the small cells for 3550-3650 proposal isn’t surprising, as even before the PCAST report Genachowski had supported the dedication of that band to small cells.
Exclusive licenses to spectrum give government agencies and private businesses the right to use that spectrum at all times and in all US geographic regions, even if it’s only needed at certain times and in certain places.
The process of clearing federal users off entire swaths of spectrum so it can be reallocated for commercial use is costly. Michael Marcus, who worked at the FCC for 25 years and is now a consultant on wireless technology and spectrum policy, points out that the auction process is burdensome for federal agencies, because the money they get in exchange for giving up spectrum isn’t received until well after they need it. Continuing an exclusionary approach won’t meet everyone’s needs anymore—the airwaves are too congested, PCAST argues. PCAST’s proposal expands upon the well-known "White Spaces" concept, in which empty TV channels are repurposed and used for WiFi networks.
If the concept were applied to PCAST-style sharing, cell phones would only transmit when they see a compatible base station, just as they do today.
Although current White Spaces deployments rely on passive end-user devices, the PCAST report banks on advances in cognitive radio technology that will put the intelligence needed to enable sharing on both the receiving and transmitting ends.
But not everyone agrees that the technological leap from White Spaces to PCAST-recommended spectrum sharing is so small.

The FCC manages 2 million active frequency licenses and the NTIA manages about 450,000 frequency assignments for government uses, Matthew Hussey, telecommunications aide to US Sen. Spectrum freed up through incentive auctions could end up being just a fraction of what the industry says it needs, but cellular companies are still "going to have to be convinced" of the benefits of sharing, Hussey said.
PCAST targets higher, perhaps less attractive spectrum than that mentioned in the NTIA report, but Calabrese thinks the strategy of using higher frequencies and building small cells across the country fits in well with a strategy carriers are already deploying, to offload cellular network traffic onto WiFi hotspots.
Targeting smaller geographic areas also makes sense in a sharing system, in which interference between conflicted uses must be avoided.

But we confirmed with an FCC spokesperson yesterday that the commission plans "to take spectrum in 3550-3650 (currently used for radar) and share it with wireless carriers," as recommended by PCAST. The group's report also supports work on tightening GPS receiver standards, in response to the failure of LightSquared to build a network that wouldn't disrupt GPS devices on adjacent airwaves. The FCC is not abandoning exclusive licenses either, as it's moving ahead with plans to auction TV airwaves to mobile carriers. The National Telecommunications & Information Administration (NTIA) has estimated it would take $18 billion and 10 years to clear 95MHz of prime spectrum from 1755-1850. Another problem: the NTIA and its Interdepartment Radio Advisory Committee act more like "chums" than "regulators" when it comes to spectrum management, in Marcus’s view. But PCAST’s plan of sharing will have to overcome technical hurdles and a lack of information—we simply don’t know what all the spectrum controlled by government agencies is used for. He says difficulties in freeing up spectrum for commercial use may well lead to increased network congestion and higher prices for consumers. So far, White Spaces has been used for machine-to-machine applications, things like video surveillance, and Internet access in rural areas where the "last mile" from the network to the homes aren’t wired, says CTO Peter Stanforth of Spectrum Bridge, which operates the first TV White Spaces database and could play a role in the broader sharing initiative proposed by PCAST.
While PCAST would greatly expand the use of spectrum sharing, "technologically it’s not a big difference," Stanforth said.
Instead of making decisions on whether to use spectrum or not, devices take their orders from above. But if a band was needed for, say, a military exercise, the base stations in the area would turn the band off.
For one thing, just figuring out what each chunk of spectrum is used for is difficult, said Michael Calabrese, who contributed to the PCAST report and is director of the Wireless Future Project at the New America Foundation.

You learn of a kind couple who provide a room for Elisha when he traveled through the region in 2 King 4. With the use of higher frequencies that don’t travel as far, cell providers will have to build lots of "small cells" instead of traditional towers.
LightSquared's 1525-1559 spectrum isn't part of the 1,000MHz targeted by PCAST, but PCAST said the controversy illustrated the need for better receiver management. PCAST proposes creation of a senior committee in the White House to oversee NTIA, a good step toward bringing "adult supervision" to the process, he said in an interview before this week's announcement. Everyone else can use the spectrum, if they make a reservation for a particular time and place. End-user devices may have to be reconfigured to use different frequencies and work within mechanisms for querying databases to find out whether spectrum is available to them.
To illustrate the complexity, he pointed to the NTIA report from March that said, "Over 20 agencies utilize more than 3,100 individual frequency assignments" in just 95Mhz of spectrum from 1755-1850. It's that higher frequencies are more easily blocked by hills and buildings and penetrate more poorly inside buildings or through forests.
Because spectrum will be shared instead of exclusively licensed, a potentially complicated system to determine who gets to use spectrum when and where will have to be implemented. Even when they have exclusive access, cell phone companies like Verizon don't always build out the infrastructure needed to use the airwaves.
In the case of Verizon, it bought spectrum in an auction, never used it, and then bought a few billion dollars worth of more spectrum from cable companies Comcast, Bright House Networks, and Time Warner Cable.
Each party exploits it for their own benefit with not concern for others.In the case of cellular, a company could save itself a lot of expense by putting its cells on top of high buildings and running high power.
Unfortunately, another cellular provider trying to use that same spectrum would find itself jammed.
Everyone else would get rotten coverage.My own sense is that everyone in the industry and at the FCC is too hung up on spectrum as the solution to everything. Use this new spectrum for the backend communications, via highly directional antennas, from microcells to a central location.* Broadcasts popular data streams via digital TV. Many people in major cities want to read the same newspapers and watch the same sporting events. Why not make smartphones smart enough to grab that data from high-powered, already assigned digital TV and store it for later use? That'd merge perfectly with subscription services.* Create something most cellular providers seem to abhor, a rationale, pay-per-byte charge for data use rather than plans that cost too much and encourage waste. There are a lot of situations where people are using cellular when they could have just have easily planned ahead and used WiFi at home or work.
