Wireless Networks: Technological Challenges and Policy Implications

Yoo, Christopher S., Wireless Networks: Technological Challenges and Policy Implications (November 6, 2013). U of Penn, Inst for Law & Econ Research Paper No. 13-31. Available at SSRN

Since June 2012, mobile wireless has emerged as the largest and fast growing medium for broadband service. At the same time, mobile wireless networks have proven considerably more difficult to manage than wireline networks. The primary causes are the rapid growth in demand for wireless bandwidth and the greater susceptibility of wireless networks to poor quality of service because of the omnidirectional propagation of wireless signals, bad handoffs, local congestion, and the susceptibility to complex interference patterns caused by multipath propagation. Moreover, the central inference underlying the primary form of congestion management is not valid for wireless networks. As a result, wireless networks adopt different approaches to error correction and congestion management than do wireline networks, which results in significantly heavier network management in ways that violate the Internet’s commitment to the absence of per-flow state and its supposed adherence to the absence of prioritization. In addition, mobile networks put significant pressure on the routing architecture by requiring the use of Internet gateways for 3G networks, accelerating the pace with which the routing architecture changes, fragmenting the compactness of the address space, and relying on a mobile IP solution that depends on a home agent to serve as a proxy in the core of the network. Proposed solutions, such as the identity/locator split, represent significant deviations from the universal address architecture around which the current architecture is designed. These considerations support the Federal Communications Commission’s decision to subject wireless broadband to a less restrictive version of its rule against unreasonable discrimination in its Open Internet Order.”

Social Security Administration – Wage Statistics for 2012

“The national average wage index (AWI) is based on compensation (wages, tips, and the like) subject to Federal income taxes, as reported by employers on Forms W-2. Beginning with the AWI for 1991, compensation includes contributions to deferred compensation plans, but excludes certain distributions from plans where the distributions are included in the reported compensation subject toContinue Reading

Research – canine companion is capable of reaching toddler-level cognition and language acquisition

TIME – article by John W. Pilley: “When people ask me how smart my dog is, I say that she has about the intelligence of a toddler. Chaser is a 9-year-old border collie who knows 1,000 words, but any dog is potentially capable of reaching toddler-level cognition and development, including learning the basic elements ofContinue Reading
