How Good is the iPhone Overseas?

The iPhone 3G is a versatile tool for the mobile communicator and computing individual and it comes with an unlimited data plan for the US only. Outside of the US, iPhone users will need to be on roaming for data transmissions which can add up quickly. The service provided by 3G networks still works the same way and provides the same speed of transmissions but, with the use of roaming the data iPhone bill will skyrocket. There are a few options available to iPhone 3G users to limit the amount of billing for use of the iPhone outside of the US for data transmission.
The first step is to turn off the roaming feature of the iPhone 3G; it is important that only the data roaming is turned off, otherwise no phone calls can be made. To turnoff the data roaming, be sure the iPhone has the latest edition of firmware and then proceed to the “settings” button. Next tap the “general” option and then the “network” option. Slide the data roaming indicator to the off position. While this works well when not using the data functions it will need to be turned on and off as needed to limit the amount of data used and transmitted.
Another option is the AT&T global data coverage. AT&T offers a data coverage program for the worldwide business person or traveler able to be used in 29 countries worldwide. This is a data package only and does not apply to phone call rates for overseas travelers. This plan only works on 3G networks and the security they provide does not translate into the use of free hotspots used by many travelers when in another country. Yes a user could use the data package to have less expensive data rates abroad but, will need a cellular network to access the Internet. In addition the end user will need to call AT&T prior to using the plan for it to be activated. With the advent of AT&T and iPhone allowing third party companies to provide data service overseas, another option is available to users of the iPhone 3G.
MobilityPass provides 3G coverage to iPhone 3G owners via service plans for wireless broadband Internet access. This service uses an international SIM card for data transmissions anywhere in the world with a 3G network. In fact, over 75 countries are included in the service which is far more than AT&T’s 29 countries. MobilityPass also provides secure and private access to Wi-Fi hotspots for use by their clients further improving the access to the Internet overseas. Every account has the option of prepaying for service or paying as the data is transmitted and no client ever has to sign a contract. Hotspots are paid for by the time used not the data transmitted. In addition a Wi-Fi Finder is provided that can export the search results to a GPS device for future reference in a business trip or family vacation. Overall, MobilityPass offers a cost effective alternative, wider coverage area and increased security when compared to other service providers.


Internet and mobile for travelers

Are you a frequent traveler? Then, I am sure that the huge international mobile phone bills must be troubling you a lot. The global roaming charges by most service providers are so high that it almost feels like they don’t want us to purchase their service. Plus, carrying 2 mobile phones – one for local while other for roaming, is another hassle that one has to endure while traveling abroad.
In today’s fast moving world, one just can’t afford to stay out of touch from anyone. No customer or client is ready to wait for you to come back to the office. The competition is so fierce that you just can’t afford to keep your clients waiting. That’s why you need a telecom service that connects you with the rest of the world without burning a hole in your pocket.
MobiltyPass is the answer to all your worries. This amazing service has everything that normal mobile phones don’t. It is the best service for business travelers or individual who travel abroad frequently. With this service, you can make and receive calls while traveling in over 120 countries with just one account. With the help of International Sim Card by MobilityPass now you don’t have to purchase a new SIM card every time you travel to a new country.
Plus, you don’t even have to keep multiple numbers as MobilityPass provides a common phone number to its clients which works in every country they have the service in. The numbers are based in US or UK. This gives you a global presence and helps your phone number become you brand.
But if you want a more local presence in the countries you regularly work in, you can add up to 60 local numbers of different countries to your account. This way, you can enjoy local call rates in all those countries. For example, if you purchase a local number of Italy, then all the calls you make to a number in Italy (from anywhere in the world) will cost you only the local call rate in Italy.
MobilityPass’s Global SIM card allows you to receive calls totally free in over 75 countries. You can also call phones in over 223 countries (that’s almost entire world) at local call rates, i.e. you won’t have to pay the hefty roaming fee on this service. As there are no binding contracts or packages attached to this system, you are free to use it for as long as you desire. You have a choice to purchase either a Single number Sim Card which is targeted for UK Travelers and Dual Sim Card which is targeted for frequent UK and US Travelers.
This service connects you with the rest of the world through top notch 3G technology. You can use this service through any wifi hotspot and the global dialup connections. Connect your smartphone, Iphone Blackberry or Laptop with internet and use this service conveniently.

MobilityPass is not just a communication service, it’s a tool that connects people and creates relationship. Don’t ignore this important quality of this product among so many other that it possesses.

Wi-Fi for Dummies: What You Need to Know

Wi-Fi is the general term used to describe any wireless Internet connection or network in a home or office. Wi-Fi, short for wireless fidelity, enables a computer or laptop user to access the Internet from the comfort of their patio, deck, bedroom or kitchen without the need for expensive and extensive hardware and cabling. Wi-Fi applies to any device that can access the Internet wirelessly and in some cases, like that of PDAs and cellular phones; it is the only way for a device to access the Internet. Wi-Fi works by transmitting data in the form of microwave radio waves that can be interpreted by receivers attached to laptops, computers and internal antennas on cellular phones.
A wireless router or tower, in the case of PDAs and cell phones, transmits a radio signal that has data encoded on a harmonic of the radio wave. This simply means that the data is attached to the radio wave to be decoded by the receiver. Protocols and advanced mathematical calculations are used in the encoding and decoding process. This information is interpreted by an internal PCI/PCI-e card or USB card in the case of laptops or desktop computers as well. Cellular phones and PDAs use the same internal antenna for Internet access as for phone calls. After decoding the data is presented in the web browser, a PDF viewer or similar program can be used for accessing documents and data.
Being able to access data wirelessly frees users form being confined to a specific location, but in the case of a home wireless network there are a few limitations on the area of transmission. Most wireless routers have a range of about 150 feet indoors and 300 feet outdoors; however, walls and furniture will inhibit some of the strength of the signal as it passes through the house or building. A simple solution to the transmission strength and area is to have a completely wireless broadband Internet connection for the computers in the home. MobilityPass offers wireless broadband Internet service with absolutely no contracts. An end user just pays for the data transmissions they use and has nothing to do with the time of day they are online.
MobilityPass enables a user to access the Internet Anywhere in France, Italy, Germany, USA, United Kingdom, Australia, Japan and from over 160 countries worldwide. In addition they provide security, privacy and confidentiality to every costumer. The company also offers an international SIM card for mobile phone users as part of their package. The beauty of Wi-Fi is that it is far simpler and less expensive than wired networking and wired Internet access. More often than not the wireless cards come standard on computers and laptops with no need for the end user to set up or configure the card. Most users will need to set up an access account for their Internet connection or access the wireless router. Accessing the Internet is as simple as entering the username and password provided by the ISP when logging on to the Internet. A password and username are set by the end user when preparing the home router for use.

What is 3G Mobile broadband and How does it Work?

Networks classified as 3G networks operate on the IEEE 802.11 protocols and were primarily developed for the use of data transmission over wireless networks. 3G is the third generation of telecommunications specifications laid down by the International Telecommunication Union (ITU). At its most basic core, 3G enables network operators a vast range of services and technologies to improve services and allow for higher capacities on networks. This is achieved through spectral efficiency; spectral efficiency defines how a particular bandwidth or frequency is used in the transmission of data in the form of voice, video telephony and general data transmissions like that of the Internet. The IEEE 802.11 networks are primarily short range and high bandwidth for data transmission and can also be used for telephone calls and video calls.
3G provides an improved speed of transmission: the average speed has not yet been standardized. Many users will be quoted different speeds according to the service provider’s documentation. As a general rule of thumb, a 3G user in a stationary position will be able to transfer at a minimum of 2 Mbit/s to a maximum of 14.4 Mbit/s. These rates change as the user moves through varying cellular towers and access points via the 3G network. At a walking pace users can expect to have a maximum transfer of: 384 kbit/s or in a moving car at 128 kbit/s. 3G also incorporates the use of HSPA for fast transmissions; HSPA is a combination of two separate mobile telephone protocols. One is for the uplink transfer (HSUPA) and the other for downlink (HSDPA) transfers.
MobilityPass 3G mobile Internet access delivers up to 7.2 Mbit/s transfer rates using the HSDPA protocol for increased speed and reliability. MobilityPass includes in every mobile Internet package privacy and confidentiality of all customer information as well as increased security for access to the mobile Internet. The beauty of the MobilityPass packages is that if the Internet is not used the customer is not billed unlike most of the competition that bills the customer regardless of usage and transfers. This makes MobilityPass a logical choice for business people around the world especially since MobilityPass has access in over 75 countries.
The standard for 3G has fallen into the UMTS or W-CDMA specification and is used in most 3G networks in one form or another. There are five other interfaces for the technologies governing the wireless Internet and telephone industries, although many are only used in remote locations that have not yet upgraded to the 3G network. The upgrade process is a long arduous one as the pre-3G technologies needed to be almost completely replaced. In many areas and countries the radio frequencies used for 3G and UMTS are completely different than those used for previous technologies. Licensing needs to obtained on these new radio frequencies which has been a problem for some companies and countries as the costs can be staggering.
While new networks need to be built and designed in areas lacking the available technology to build on, 3G has taken a decent portion of the world’s data services. In the countries where 3G was first launched, Japan and South Korea, 3G subscribers now account for 70% of the market. In countries such as the US and Europe it is closer to 30% and rising on a monthly basis.

When was the first mobile phone invented?

2009/12/23 1 comment

The first mobile phones where actually two way radios systems using telephone systems to communicate; however, mobile users could not dial in specific numbers and technically are not considered cellular phones. The technology used by the two way radio systems is the basis for all cellular phone technology now in existence. Cell phones are called cell phones due to that fact that each part of the coverage area is split into “cells” of hexagonal shape and the initial idea was developed at Bell Labs in 1947. The proposed structure of the cells had transmission towers that broadcast in three directions into three adjacent cells and were placed on the edges of the cells instead of the center for optimum coverage.

This technology was not further developed as the hardware needed had not been developed; frequencies had not been allocated for use and the technology remained mostly underdeveloped until the 1960s. There were a few instances of direct dialing from a phone as far back as the 1950s but was limited to particular areas and service was rare in most cities. The MTA, Mobile Telephone System A, was released in Sweden in 1956 by the Ericsson Company and was the first independent dialing system introduced to the market. It did have the disadvantage of having a very heavy phone weight of over 80 pounds. At the same time a Russian was developing a “radiophone” that was wearable and had an effective cell range of about 40 miles. In 1970 there was service for the phones in over 30 USSR cities; this was the first year of analog cell phones in the US which was introduced by Motorola.

Also in 1970 was the advent of cell handoffs which allows for different service areas to exchange the phone call between them and was developed by Bell Labs; the modern version of this is called roaming. Soon after in 1971, AT&T petitioned the FCC for the use of cellular phone networks which was finally approved in 1982 after a long and arduous debate. The first commercially and publicly available network of cellular services was released in Finland in 1971 and was called ARP; this network and its protocols is referred to as the 0G generation of cellular technologies. All of these early networks used analog transmissions until 1990 when digital transmissions took over in the cellular arena rushing in the advent of the 2G network protocols and technologies. Prior to the 2G network phones resembled “bricks” and while they could be ported from place to place did not bode well in personal mobile communication.

The 2G network saw a drastic rise in the number of people using cellular phones and networks ushering in the more modern look and size of today’s cellular phones. The first digital networks superseded the 1G analog networks and brought to the public SMS text messaging as well as the ability to retrieve and use media and content from companies such as downloadable ringtones. Due to this rise in the text messaging and downloading as well as an increase in the need for web access and data usage on cellular networks the 3G standard was pursued. The 3G network, which can be accessed using MobilityPass mobile broadband Internet services, was not standardized in technology but one of the requirements of data transmission.

How Do I Increase my Wireless Signal Strength?

The main area of concern in using wireless Internet and signals for networking is the signal strength. Signal transmission strength determines the area that can access the Internet through the transmission towers or antennas. Starting with a home or WLAN in a community or business office, there are several options which an individual can use to improve their signal strength. The first option is to simply move closer to the transmission point; either the wireless router or transmission tower/antenna. In the case of a desktop computer this will be an unlikely solution, but for laptops and mobile computing devices, this should help with the signal strength. If the desktop is using an internal card, either PCI or PCI-e, check on the age and model of the card. Odds are that replacing the card with a USB modem will help tremendously.

The best part of a USB modem is that it can use an extension cable to enable the end user to place the receiving USB modem closer to the signal tower or transmission point. Should this not improve the signal, consider using a high gain antenna to capture more of the signal being transmitted that can then be directed to the Internet device. Since the Internet signal is a radio signal it operates just as a television set does, not connected to cable of course. The antenna needs to be in the line of sight of the transmission tower or antenna. Essentially the user needs to be able to see the tower for best results, but this is not always true.

If the position of the tower is known and is only blocked by a few trees, then the antenna may be placed in close approximation to the location of the tower. The cable from the antenna on top of the building to receive the Internet signal can then be brought into the building and by using a wireless router, split to all of the home computers. The taller that antenna the better; in some instances a high gain satellite dish would also work as they are simply modified antennas. Working in a home wireless network has far more options than on a mobile wireless Internet but, some tricks can be applied to improving the signal in a mobile wireless setting or using a wireless Internet connection in a home or office.

The best way to improve a mobile or completely wireless Internet connection is through the use of an antenna just as with a home solution. The difference here is that the antenna will need to be placed on the exterior of the car, just like with the original cell phones. Small antennas may be purchased either at a local store or through the provider of the wireless Internet in some cases. The signal strength in wireless Internet settings is determined by the provider and the FCC, in some cases they cannot increase the strength from the towers due to regulations. In other cases it is simply the lack of towers the provider has at its disposal. MobilityPass has towers in over 75 countries around the world to improve signal strength and access to the Internet. The user can choose Wi-FI hotspots or continuous wireless Internet for their access options and there are absolutely no set up fees and no recurring billing; pay only for time used. The antennas are sometimes called repeaters and some even come equipped with amplifiers to increase the strength even more. Careful attention should be paid to the antenna’s power requirements, if any exist.

How to Use IPhone 3G

The IPhone 3G is a combination of multiple functionalities culminating in a resourceful and versatile digital device. The 3G designation is not a designation of the version of the IPhone but, a designation of the data transmission technology being used. 3G allows for the fast transmission of data and information for use over the Internet by mobile computing devices. The basic specifications of 3G are that it transmits data up to 14.4 Mbit/s on the downlink and 5.38 Mbit/s on the uplink. This delivers faster surfing and improved video call functionality. With IPhone 3G an end user can be on a call and surf the web simultaneously.

By implementing a dual channel transmission, the new IPhone 3G offers higher flexibility and better performance to its users. This feature will enable a user to determine where to meet with friends or family while out on the town. All IPhone 3G phones will automatically recognize if a 3G network is available and connect to it automatically. The downside is that 3G networks are not available everywhere and in those cases the IPhone will use the provided network protocols for data transmission; in most cases it will be either a 2.5G network or an EDGE network. The IPhone 3G is more than just a phone with Internet access; it is a fully functional portable pocket computer with a phone.

The IPhone 3G can connect to any Wi-Fi network and keep the user informed of all updates via email and text messaging. Many users may want to upgrade their old IPhone to the 3G version of technology. Unfortunately, this is not possible. 3G requires new and specialized hardware to perform at its peak and the old versions of the IPhone cannot be upgraded to work on a 3G network. The 3G has an average download speed of 1.4 Mbs which is two to four times as fast as the EDGE network. Downloading music, files and images has never been easier and a user can do it while talking to their friends and family. Due to the nature of activation the IPhone 3G has to be activated in an Apple store or AT&T store in the US and not through iTunes.

The built in GPS locator is perfect for Geotagging images taken on a trip but, the GPS for directions has no voice commands so a co-pilot will be needed for determining the directions to the intended destination. A multitude of applications exist for the IPhone 3G from image apps to social networking and bookmarks. Of course the IPhone can be synced with a calendar, email, media or newsgroup account for constant connections to the most important pats of connectivity for users. MobilityPass offers 3G coverage with security, privacy and confidentiality to IPhone 3G users worldwide from over 75 countries and over 100,000 hotspots. Pay no activation fee and sign no contracts as users and clients can pay as they go and only pay for the data transmitted. They offer virtual private networking with every service plan securing the connection even further.
