SOP 202 Iridium Satellite Phone Provisioning
Standard Operating Procedure Updated: Apr 27, 2017 DOCUMENT NUMBER: SOP202 TITLE: Iridium Satellite Phone Provisioning PURPOSE: This document describes the provisioning and testing of Iridium Satellite phones. It is intended for all Greenland and Alaska field site personnel. BACKGROUND: A satellite telephone, satellite phone, or satphone is a type of mobile phone that connects to orbiting satellites instead of terrestrial cell sites. They provide similar functionality to terrestrial mobile telephones; voice, short messaging service and low-bandwidth internet access are supported through most systems. Depending on the architecture of a particular system, coverage may include the entire Earth or only specific regions. DETAILS: Components Required for Testing • Activated sim chips with phone number labels from IT&C staff • Preconditioned and charged batteries • External iridium egg antenna deployed outside in order to receive satellite signal inside the building • Updated Iridium phone number cheat sheet and Quick use guide Iridium Satellite Phone Testing Procedures • Insert activated SIM chip into satphone • Insert a preconditioned and charged battery into the satphone.. • Place battery cover on the satphone • Connect the satphone being tested to the external iridium egg antenna using a stubby antenna connector • Turn on the satphone and allow the registration process to complete Page 1 of 3 Standard Operating Procedure Updated: Apr 27, 2017 • Make a phone call using the satphone to a known number (ie your cellphone number, land line or a known working Iridium phone) • Make a phone call using your cellphone number, land line or a known working Iridium phone to the satphone being tested. • Adjust the iridium phone audio speaker to highest volume • Set the iridium phone to Ringer only and adjust the ringer to the highest volume • Turn call Forwarding off • Per each phone, adhere the phone number label to the front of the Iridium phone • If above test passed, continue onto next section. -

ABSTRACT Mobile phone has made our communication easier. It is used for sending and receiving text messages, calls, E-mails, games, camera. Mobile phones are said to be in active mode, when they receive calls or make calls, sending and receiving text messages and when it is connected to internet. Some people uses mobile phone in unnecessary places where mobile phones are prohibited. Mobile phone detector is a device used to detect the active mobile phone in unauthorized places. It receives the radio frequency signals from mobile phones through antenna and indicates the use of cell phones by LED and buzzer. This device is useful for detecting the use of mobile phone in examination hall, during meeting and plane stations. -

A tremendous increase in handover (HO) scenarios and HO rates will occur. Ensuring stable and reliable connection through the mobility of user equipment (UE) will become a major problem in future mobile networks. This problem will be magnified with the use of suboptimal handover control parameter (HCP) settings, which can be configured manually or automatically. Therefore, Citation: Saad, W.K.; Shayea, I.; the aim of this study is to investigate the impact of different HCP settings on the performance Hamza, B.J.; Mohamad, H.; of 5G network. -

Prospects for Improving Competition in Mobile Roaming
WIK Wissenschaftliches Institut für Kommunikationsdienste GmbH Prospects for improving competition in mobile roaming Ulrich Stumpf Paper prepared for the 29th TPRC 2001, 27 - 29 October 2001, Alexandria, Va. Prospects for improving competition in mobile roaming I Contents Abstract II 1 Introduction 1 2 Basics of international roaming 2 3 Supply-side of wholesale roaming markets 7 3.1 Small number of suppliers and high market concentration 8 3.2 Spectrum scarcity and second-mover disadvantages 9 3.3 Imperfect substitutes to wholesale roaming 12 3.4 Transparency of competitors’ IOTs 13 4 Demand-side of wholesale roaming markets 13 4.1 Lack of competitive pressure in downstream retail roaming markets 14 4.2 Customer ignorance, insufficient control over network selection, and demand externalities 17 5 Conclusions and implications for application of non-discrimination rules 21 References 23 Prospects for improving competition in mobile roaming II Abstract The ability to make international roaming calls is of increasing importance to customers. However, there are various complaints that prices of retail roaming are intransparent, rigid and at levels that are unrelated to the cost of carriage. The focus if the paper is on wholesale roaming, which is the prime determinant of retail roaming prices. The paper analyses the structural conditions of wholesale roaming markets that have impaired incentives to competition, namely (1) high combined market share of the two leading operators combined with second mover disadvantages, and (2) demand externalities associated with customer ignorance and lack of control over network selection. The paper argues that a number of developments are under way that are likely to modify this situation in the future. -
