Communications Payload Pod is mounted to a pylon under the fuselage. 0.8 tonne weight communications pod Each cell covers a small geographic area, e.g., 4 to 8 square miles. The wide and narrow beamwidths within each beam or cell are achieved by using MMW frequencies. Small aperture antennas can be used to achieve small cells. An ATM-like packet switch provides the network switching capability to cross-connect all users within the coverage area as well as connections to other users through gateways. The elements are MMW transceivers, pilot tone transmitter, high-speed modems, SONET multiplexers, packet switch hardware and software
It is relatively simple. It comprising a Radio Frequency Unit and a Network Interface Unit. The Radio Frequency Unit contains the steerable dish antenna, a millimetric band transmitter , a millimetric band receiver, and the antenna steering mechanism.
It contains the modulators and demodulators for the signal. The feed to and from the Radio Frequency Unit is done in the 1.4 GHz band, with up/down conversion performed in the Radio Frequency Unit. BEN. JOHN , S N G C E

The HALO Aircraft is also called Proteus Aircraft.
Halo Networks
The Proteus is built with composite materials. Weight -- 6.4 tonnes Engine Type -- Williams FJ44-2E jet engines. Seating for two pilots, with an extra seat for a relief pilot or passenger. The cabin is pressurised and high altitude pressure suits are not required.

Ease of Installation
1. The Consumer Premise Equipment (CPE) , whether delivered or purchased through a retailer, is designed for rapid installation and ease of use.
2. The antenna is self-pointing and is mounted on an outside area offering a clear view of the HALO™ aircraft.

Halo Networks
Provides data densities nearly one thousand times higher. It has high power available to their payload. The HALO Network integrated with a satellite network can increase the throughput, competitiveness, and revenue of a satellite constellation. Because of the relatively short distance between the HALO node and the end user (10 to 35 miles), low-cost, low-power premise equipment can be used. The HALO Network can serve hundreds-of-thousands of broadband end users on a metropolitan distance scale.

O ver Terrestrial network
Terrestrial networks have low look angles and complex infras tructure. They require many base stations that must be interlinked with cables. The communication paths have low look angles with multipath R ayleigh fading. E ach time cell splitting is used to increase system capacity, the network can demand significant reengineering

Halo Networks To HALO-satellite global network : The stratospheric HALO aircraft offer three benefits to an integrated HALO-satellite global network: 1. As HALO aircraft are high above the atmosphere, they easily link to numerous satellites. 2. HALO-to-satellite link use very high carrier frequencies offering ultra-wide bandwidths. 2. The HALO be the front-end of an integrated system.
Widely separated customers can receive same communication as in entertainment broadcasting. We can acces s interactive TV and internet. C ustomers can have large coverage area in telecommunication compared to terrestrial network. C an us e as a communication techniques for remote areas. C an us e in marine communication system.

Halo Networks
The HALO Network can provide wireless broadband communications services. The HALO/Proteus airplane will be the central node of a broadband communications network, the HALO Network, having a star topology. The network will utilize packet switching to offer bit rates to each of thousands of end user in the multi-megabit per second range. A variety of spectrum bands licensed for commercial wireless services could provide the needed MMW-carrier bandwidth. The signal footprint of the network, the Cone of Commerce, will cover a typical large city and its surrounding communities. HALO aircraft will fly above commercial airline traffic. A fleet of aircraft will be operated in shifts to achieve around-the-clock service. Finally, the HALO Network will be an evolving "network solution" that can be deployed one market at a time to ease the financing commitment of growing a global business.
