1. Al-Shoukairi, Maher. Performance of hard handoff in 1xev-do rev. a systems.

Degree: 2009, Texas A&M University

1x Evolution-Data Optimized Revision A (1xEV-DO Rev. A) is a cellular communications standard that introduces key enhancements to the high data rate packet switched 1xEV-DO Release 0 standard. The enhancements are driven by the increasing demand on some applications that are delay sensitive and require symmetric data rates on the uplink and the downlink. Some examples of such applications being video telephony and voice over internet protocol (VoIP). The handoff operation is critical for delay sensitive applications because the mobile station (MS) is not supposed to lose service for long periods of time. Therefore seamless server selection is used in Rev. A systems. This research analyzes the performance of this handoff technique. A theoretical approach is presented to calculate the slot error probability (SEP). The approach enables evaluating the effects of filtering, hysteresis as well as the system introduced delay to handoff execution. Unlike previous works, the model presented in this thesis considers multiple base stations (BS) and accounts for correlation of shadow fading affecting different signal powers received from different BSs. The theoretical results are then verified over ranges of parameters of practical interest using simulations, which are also used to evaluate the packet error rate (PER) and the number of handoffs per second. Results show that the SEP gives a good indication about the PER. Results also show that when considering practical handoff delays, moderately large filter constants are more efficient than smaller ones. Advisors/Committee Members: Qaraqe, Khalid A.

2. Kuruc, Jiří. Podpora kvalitativních požadavků služeb v rádiových přístupových sítích vysokorychlostních variant mobilních sítí .

Degree: 2009, Brno University of Technology

Diplomová práce pojednává o vývojových stupních (Releases) sítí třetí generace UMTS. Vy-světluje dílčí vylepšení od Release 99 k Release 5 a Release 6 vedoucí ke zlepšení kvalitativ-ních parametrů především mobilních datových přenosů. V praktické části jsou proměřeny kvalitativní parametry všech sítí třetí generace do-stupných na území České republiky: UMTS, HSDPA, CDMA 1xEV-DO Rev.0 i Rev.A a UMTS-TDD. Měřením byly zjištěny reálně dosažitelné rychlosti přenosu dat k i od uživatele, doba odezvy, kvalita VoIP hovorů spolu s rozptylem doručování paketů a ztrátovostí a schop-nost sítě přenášet videohovory o různých datových tocích. V rámci každé sítě byly zhodnoce-ny i další aspekty, především pokrytí a dostupnost koncových terminálů. Práci doplňuje labo-ratorní úloha zaměřená na praktické srovnání základních parametrů datových přenosů v sítích druhé a třetí generace.; The work deals with the developmental stages (Releases) of the third generation UMTS net-works. It explains a partial improvement from Release 99 to Release 5 and Release 6 to im-prove the quality parameters of a mobile data transmission. In the practical part, there are measured qualitative parameters of the third generation networks that are available in the Czech Republic: UMTS, HSDPA, CDMA 1xEV-DO Rev.0 and Rev.A and UMTS-TDD. The measurements give reasonably achievable data rates in both directions (downlink & uplunk), a response time, quality of VoIP calls, a dispersion, a data-loss and an ability to transmit video with different data flows. The other aspects especially an availability of coverage and end-user terminals have been assessed wihin the each network. The work is supplemeted with a laboratory, which is focused on a practical comparison of the basic parameters of data transmissions of 2G and 3G networks. Advisors/Committee Members: Novotný, Vít (advisor).
