Extractions: Following is a highlight of some new features. Flexible architecture that allows people to easily build different components at different layers. The nested header structure allows each component to freely define its own packet formats and add its header fields in packets from upper layers. Clean separation of MAC and PHY allows different MACs can be built on the same PHY. The PHY can reliably and efficiently handle variable length packets up to 250 bytes, and is robust to back-to-back packet transmission. S-MAC provides energy-efficient operations on radio Low-duty-cycle operation on radio trades off latency for energy savings. Overhearing avoidance sleep when neighbors are talking Abundant features in unicast provided by S-MAC (similar to IEEE 802.11).

Extractions: UNHCR Procedure for Radio Communication 1. Check that the RadioSet is prepared for operation 2. Transmitting Decide beforehand what you are going to say, ensuring that it will be clear and concise. Make notes if necessary. Check that no-one else is speaking on the net before you start. Do not attempt to use Selcall (HF Mobiles/Base) if the net is busy. If your message is long, divide it into sensible phrases, pause to allow your message to be understood (and written down if necessary) while maintaining a natural rhythm. Use standard pronunciation. Emphasize vowels sufficiently. Avoid extremes of pitch, do not let your voice drop at the end of a sentence. Speak in a moderately strong voice but do not shout as this will distort the signal. Hold the microphone at about 5cm from your lips while speaking. Shield the microphone from background noises. Be aware that everything that you say can be heard by anyone using a radio receiver on the same frequency. Depending on the situation in the country of operations, it may be wise to use simple codes (e.g. AlphaNumeric codes for locations, cal signs for names, etc.) Ensure that each user on the network is registered on a master list held by the Radio Room, and that any unauthorized call signs heard on the net are noted and the users (if known) are properly registered or informed that they do not have permission to use the network.

Wireless For The Warrior. The History Of British Army Radio
This web site is primarily devoted to the history and technical development of British Army radio communication equipment up to the 1950s.
http://home.wxs.nl/~meuls003/

Extractions: Welcome to the home page of Louis Meulstee. He is the author of "WIRELESS FOR THE WARRIOR", a series of books devoted to the technical history and development of British Army radio communication. In this web site you will find basic technical descriptions and photographs of many vintage radio sets once used by the British Army. In addition, there are also posted numerous other subjects for example: line telegraph (the Fullerphone), Air-Sea rescue sets (Gibson Girl), a gallery with Soviet radios and various other subjects which are not really connected with British Army radio communications! Please note that the pages in this site are regularly updated and renewed. Especially the gallery section, which will be much more extended in the future. This will not be done on a scheduled base as I have a rather time consuming job (see below) and am NOT retired from the Army... Some time ago I added a page on the history of the company I work for ( Business Radio Solutions , a department of KPN Royal Dutch Telecom) entitled: Mobile Radio in the Netherlands.

http://www.rohde-schwarz.com/mobile_radio/cmu300.html

Extractions: For sensitivity measurements on a WCDMA Node B (WCDMA terminology for the base station), the CMU300 is the first test instrument to support all the Reference Measurement Channels (RMC) as defined in the specification (3GPP TS 25.141). By virtue of its own RF generator, the Universal Radio Communication Tester CMU300 provides: Real time signal generation incl. measurement sequences up to PN (pseudo-random noise) 16 for continuous receiver measurements, providing easy implementation of search routines for the absolute radio sensitivity Support for the specified 2 Mb per second data rate (RMC 2048 kbps) makes it possible to test already for a data rate implemented for anticipated applications: Test today for the applications of tomorrow For multislot applications, the Universal Radio Communication Tester CMU300 provides a feature ideal for testing transmitters that support both GMSK and 8PSK modulation. Not only can the CMU300 test the power ramping for up to 4 consecutive bursts; the measurement adapts automatically to the modulation, either GMSK or 8PSK, required for the power ramping used in each burst separately. When a base station provides hopping this must be tested, to the GSM Specification for base stations (3GPP TS 11.21). So it is important that the Universal Radio Communication Tester CMU300 meets this requirement not only for GSM, but also for GPRS and EGPRS. The CMU300 supports two forms of hopping; Activation by Call, and "Forced Hopping" - activation without a call. Forced hopping supports the GPRS and EGPRS channels. For either form of hopping, software version 2.84/2.94 or later is required.
