Wireless Communications

With almost all the media attention on the evolution of 3G/4G Wide Area Networks (WAN), advancements in Metropolitan Area Network (MAN) technologies such as WiMAX, and Wireless Local Area Network (LAN) improvements through 802.11n and MIMO, many people do not realize the role, importance and market opportunities for Personal Area Network (PAN) solutions. Whereas WAN, MAN, and LAN solutions are often focused mainly on coverage for bearer communications, PAN provides a “last meter” solution for application personalization as well as opportunities for non-voice communications, machine-to-machine (M2M) communications, and a variety of next generation applications and application-enablers such as presence detection, identify recognition, and more.This report provides the reader with everything needed to understand PAN technology, solutions and market opportunities. The report covers technical options, standards, commercial applications, trends and the future of PAN. It also discusses PAN ve...

Urmarind ultimele conferinte ale unor companii importante din domeniul telecomunicatiilor, nu puteam sa nu remarcam accentul pus pe migrarea catre retelele IP („Internet Protocol”). S-a vorbit, de fiecare data, de avantajele pe care le implica aceasta schimbare, toata lumea fiind de acord ca retelele IP reprezinta cea mai buna solutie, indiferent de bucla locala instalata pentru fiecare client in parte. In acest caz, prin bucla locala intelegem solutia de legatura intre reteaua clientului si reteaua principala a furnizorului de servicii de telecomunicatii, solutie care poate insemna comunicare fara fir, prin intermediul unui cablu etc. Prin urmare, „fundatia” unei retele principale (de „core”) pentru un furnizor de servicii telecom va fi construita pe „lumea IP” si pe tot ce presupune aceasta. Nu vom insista asupra avantajelor - deja binecunoscute - ale acestei migrari. Ne vom opri insa asupra unui aspect foarte interesant, care a fost ignorat, o perioada, de mai toate companiile de te...
