Unit 1: Introduction to Wireless Networks

wireless networks generates new research problems. This paper examines the ways wireless Notes
technology work and the required prerequisites to integrate it into the educational area. It also
describes educational opportunities and challenges of teaching in a real time wireless classroom
environment. Additionally, this paper refers to the constraints and barriers, which prevent
wireless networks from being accepted. It provides educational models and techniques in order
to easier the transition from traditional computerized training systems to wireless training
systems. Lastly, the paper compares models and architectures in educational wireless networks,
taking into consideration the shortages of the educational systems, and predicts future trends
and perspectives of integrated educational environments.

1.3.5 Utilities

Trango microwave communications solutions are ideal for a wide variety of industrial applications
in the utility, energy, oil & gas sectors. Remote monitoring, video, and site interconnectivity
applications require low latency, high reliability, and high capacity capability of licensed band
solutions from Trango Systems.

Utility and energy providers require reliable networks to carry critical traffic with advanced
information security, high capacities and failsafe reliability.Trango Systems’ TrangoLINK Sparta
Elite™ is the most secure microwave Ethernet point to point system on the market, utilizing
integrated NSA Suite B compliant FIPS-197 certified AES256-GCM real-time encryption. The
Sparta Elite is also FIPS140-2 and HIPAA compliant, with secure management interfaces over
SSH, HTTPS.
In addition to advanced information security, the Sparta Elite features Intelligent Payload
Compression (IPC) which compresses packets in real time to provide capacity improvements up
to 2.5 x the raw data rate. If the compression does not yield an improvement, the packet will go
through uncompressed. Latency is typically only increased by 100 microseconds and in the case
of larger packets may be reduced.
!

Caution Compression ratio is content variable and can be monitored using the management
interface. Both compression and encryption can be used simultaneously.

1.3.6 Field Service

A field service organization has five key applications: billing, systems management for remote
devices, corporate IM, a Web-based CRM application and email. The field technicians carry
laptops throughout the day, and use them occasionally at home and in a branch office. The
laptops have a number of background applications which have been installed by the operating
system, such as Windows Update, or come from third parties, such as automated antivirus or
printer driver updates.
The field technicians typically spend 32 hours a week in the field and 8 hours at a regional office.
While in the field they are connected via a wireless carrier’s data network. At the regional office
they connect via an in-building wireless LAN.

1.3.7 Field Sales

There’s nothing more crucial to your company’s bottom line than sales—and yet your sales force
may not have the tools they need to be performing at their potential.Ultimately, that means less
revenue for the company. Not to mention less satisfied customers.
Wireless software ensures that your sales force stays securely connected to the applications they
need to answer customer questions, input data into your CRM and make the sale, all right from
the customer site. This means improved service, more sales, and less travel time for sales reps.
