The High Altitude Long Operation (HALO) network is a broadband wireless Metropolitan Area Network (MAN) consisting of HALO aircraft operating at high altitude and carrying an airborne communications network hub, with network elements on the ground.. It will provide broadband services to businesses and to small offices home offices in an area containing a typical large city and its neighboring towns. To each end user, it will offer an unobstructed line of sight and a free-space like channel with short propagation delay, and it will allow the use of low power low-cost user terminals.

Abstract
The word on just about every Internet user's lips these days is "broadband." We have so much more data to send and download today, including audio files, video files and photos, that it's clogging our wimpy modems. Many Internet users are switching to cable modems and digital subscriber lines (DSLs) to increase their bandwidth. There's also a new type of service being developed that will take broadband into the air. In this paper, we'll learn about the future of the Airborne Internet. We'll take a look at the networks in development, the aircraft and how consumers may use this technology.
Land-based lines are limited physically in how much data they can deliver because of the diameter of the cable or phone line. In an airborne Internet, there is no such physical limitation, enabling a broader capacity.
The airborne Internet will function much like satellite-based Internet access, but without the time delay. The airborne Internet will actually be used to compliment the satellite and ground-based networks, not replace them. These airborne networks will overcome the last-mile barriers facing conventional Internet access options.
This paper addresses some of the trends and issues involved in developing an Airborne Internet capable of achieving this goal. Understanding relationships between these trends and issues and the objectives and functional requirements of the program will allow various participants in this complex program to keep activities in proper perspective. The all-round development and improvement are the key areas of research work performed in this paper.

Traffic Offloading Solutions: Femto, WiFi and Integrated Femto-WiFiShristi Pradhan
I provide a comprehensive overview on various traffic offloading solutions:
1. Femtocells, which provides the benefits of scalability, automatic configuration and self-optimization.
2. WiFi, widely available in homes and hotspots.
3. Integrating femto and WiFi together to reap the benefits of both femtocell and WiFi technology.
Pervasive Internet and the Push Towards ConvergenceBrenda Bell

Cellular Internet of Things white paperBjörn Ekelund
GSM is widely used today for millions of devices, as its costs are relatively low, but mobile broadband technologies are more expensive, may have worse coverage, and take too much power for things that may have to work for years on small batteries. Though many “things” may be connected using short range wireless, many more will be beyond the reach of systems like Bluetooth, Wi-Fi or Zigbee.
A group of industry players, including network and device suppliers, operators and academics, brought together by Vodafone, has been looking at the problem of supporting the “Internet of Things” for the past year and has recently published a White Paper outlining the options. These include further new features in LTE that would be defined through 3GPP; or an alternative “clean slate” cellular standard defined specifically to meet the needs of the IoT. Any future system will need to connect “things” that don’t have large amounts of data to communicate; can be in hard-to-reach locations such as manholes, meter closets, and in very isolated locations; and need to operate for years on small batteries.
Case for Layer 3 Intelligence at the Mobile Cell SiteAviat Networks
Mobile cell sites are transitioning from simple Layer 2 connected sites for voice and low-speed mobile data access to multi-functional hubs for delivery of new services built on Layer 3 intelligence.

The High Altitude Long Operation Network is a
broadband wireless metropolitan area network,
with a star topology, whose solitary hub is
located in the atmosphere above the service
area at an altitude higher than commercial
airline traffic.
The initial capacity of the network will be on
the scale of 10 Gb/s, with growth beyond 100
Gb/s.
The HALO/Proteus airplane is the central node
of this network.
It will fly at altitudes higher than 51,000 ft.
4.
The HALO Network is capable of providing
high rate communications to users of
multimedia and broadband services.
The feasibility of this approach is reasonably
assured due to the convergence of technological
advancements.
These technologies are individually available, to
a great extent, from commercial markets.
The HALO™ Network seeks to integrate these
various technologies into a service of high utility
to small and medium businesses and other
multimedia consumers at a reasonable cost.

"The demand for Internet services is exploding
and this creates a strong demand for
broadband, high data rate service. It is
expected that there will soon be a worldwide
demand for Internet service in the hundreds of
millions". (Lou Gerstner, IBM, April 1997) The
growth in use of the World Wide Web and
electronic commerce will stimulate demand for
broadband services.
6.
There are various facts that show the strong
interest in wireless communications in India:
50
million subscribers to wireless
telephone service
28 million dollars annual revenue for
wireless services
38,000 cell sites with 37 billion dollars
cumulative capital investment
40% annual growth in customers
25 million personal computers sold each
year
50 million PC users with Internet access
7. High-Speed Data Links Transmitted Over Millimeter Wave Frequencies Provide
Broadband Data Services to Various End-Users
8.
The key features of the HALO Network are
summarized below.
Seamless ubiquitous multimedia services
Adaptation to end user environments
Enhanced user connectivity globally
Rapidly deployable to sites of opportunity
Secure and reliable information transactions
Bandwidth on demand provides efficient use of
available spectrum
9.
Most metropolitan areas will fit within a signal
"footprint" of 40-60 miles diameter.
The following figure shows the coverage of a 50mile HALO™ Network service-area footprint
for the New York City metropolitan area.
Notice that "double coverage" of certain areas
occurs due to overlapping adjacent footprints.
This provides higher reliability links and
reduces blocking factors on requests for service.
The footprint over Manhattan covers 4.8 million
households or 12.5 million people.

The HALO Network accommodates the following
design objectives:
Seamless

Rapidly
deployable to sites of
opportunity
Bandwidth on demand for efficient use
of available spectrum
13.
The HALO network has several advantages over
terrestrial wireless networks. The latter have
complex geometries involving many base
stations interlinked by cabling or microwaves.
On the other hand, satellite networks require
more expensive terminals with high power to
achieve the same data rates possible through the
HALO Network.
The capacity of a satellite network can be
increased, but at higher expense than the HALO
Network, typically only by adding more
satellites.
14.
The HALO network will provide wireless
broadband communication services. The feasibility
of this network is assured due to a convergence of
technological advancements.
The HALO Network is predicated on the
successful integration of these technologies to offer
communications services of high quality and
utility to small and medium-sized businesses at
reasonable prices.
While a variety of broadband access modalities are
promising for the U.S. markets, the HALO
Network may be a winner for "green field"
deployment, especially in regions where the
existing infrastructure is not amenable to an
upgrade or retrofit.
