According to FCC filings, Qualcomm is developing a chip that could resolve interoperability problems on the 700MHz spectrum band, but the issue isn’t fixed yet. The 700MHz block is currently used by AT&T, Verizon, and smaller US carriers, but they operate on different blocks, and regional carriers have complained about not being able to get hardware that operates on their bands or being unable to let their phones roam on larger networks. A new chip apparently being sped through development by Qualcomm, however, could solve these problems. In the filing, Qualcomm said its chip could be configured by manufacturers to work on a carrier’s normal band but roam on a different one. At the same time, it says there are “significant device…
Tor and several other related imprints may be going DRM-free in July, but that doesn’t mean the rest of the publishing industry is ready to jump on board. Instead, the International Digital Publishing Forum — the association that established and maintains the ePub standard — is proposing a new lightweight DRM scheme that will provide protection while still allowing interoperability between ebook platforms. In a post on the IDPF’s website, Bill Rosenblatt writes that while ePub provides the basic tools for encryption, the lack of a fully-realized DRM system has led to distributors and device makers rolling their own, resulting in fragmentation and platform lock-in. (As it currently stands, vendors like Apple and Barnes & Noble use…
Last month Verizon announced that it would be willing to sell off its unused 700MHz spectrum licenses — if the government agreed to approve its purchase of $ 3.6 billion worth of spectrum from several cable companies. US Cellular appears to be interested, with the company’s CEO Mary Dillon recently meeting with FCC Chairman Julius Genachowski to discuss the matter, while also pushing the FCC to take a stance in ensuring interoperability between 700MHz networks. According to a follow-up letter sent after the meeting, US Cellular stated that it could greatly help LTE devices running in band class 12 — one of four band classes used within the 700MHz spectrum — but that it didn’t need to do the heavy lifting itself. A purchase of the…

iPhone 5 to Support Two SIM Cards for Network Interoperability? is a post from: Gadgets DNA
Through some legit sources, iDealsChinaÂ is now claiming that the iPhone 5 will accompany two SIM cardsÂ to support two phone lines. Don’t take it otherwise! This same teaser site earlier dangled the original 4th Generation iPod Nano, edge-to-edge screen design images and iPhone 5 panel with thinner bezel before our eyes.
Heard from a reliable source that iPhone 5Â will supportÂ 2 sim cards allowing you to use 2 phone lines. We hope to see some proof.
Since Verizon iPhone 4 is using Gobi chip that supportÂ both GSM and CDMA network, we can assume that the 5th generation iPhone could use the same chip and offer true dual-mode functionality.Â It is worth noting that some of the CDMA networks (Outside US), does require SIM card.
Dual-SIM card functionality could allow users to use iPhone 5 on other carrier keeping the initial contract with carriers intact. When traveling, a user could simply configure setting (per carrier), after inserting another SIM, to swap out carriers as required.
As pointed out by GigaOM, dual-mode iPhone 5 would also decrease Apple’s supply chain costs in the long run, and make the phone usable in a number of previously unreached international markets, too. CDMA isn’t nearly as popular as GSM internationally, but thereÂ are markets where it on fairly equal footing with GSM. Apple would be gain significantly from selling a phone in these markets with network interoperability.
iPhone 5 is speculated to be released in July or June at WWDC 2011,Â without rear glass surface. We will update you as soon as we get more tidbits on iPhone 5. Just follow us onÂ twitter or join ourÂ facebook fanpage. ViaÂ 9to5Mac,Â iDealsChina.
