iTelNet's Place in Mobile Internet

Like most smart business people, you’re hopefully looking to ensure your company takes advantage of new technology. Assuming so, fast mobile internet is something you have to consider. ItelNet, as a leader in business phone and internet service of all types, has made it a “corporate commandment” to keep our customers aware of everything that can help their business, and that includes making sure we offer the best mobile internet products.
We offer air cards, which can be attached to any computer to provide mobile internet access that is faster than dial up. But air cards are not as fast as small business DSL (and certainly not as fast as a T1), plus air card technology is not totally reliable, so we don’t recommend air cards as your main source of mobile internet service. However, we do recommend air cards for your business laptop, so that you can get internet access when you travel, etc.
We also offer business cell phone plans that include mobile internet. And we can offer business WiFi installation, to make your entire office complex as wireless hotspot. Call us today at 1-800-677-0836 to speak with an experienced telecom executive about out products and how we can save your business money. Or, click here to email us.

The Past (The Telephone)... and The Future (The Mobile Internet Capable Cell Phone)

It has been convincingly argued that the telephone was the most important communication device of the 20th century. If true, then the landline has now effectively passed the torch to its wireless progeny and its digital capabilities.
The transformation of mobile phones from transmitting only voice data to giving consumers mobile Internet access and other multimedia broadband capabilities has unfolded rapidly and changed not just the face of modern technology but the daily personal and professional lives of people across the globe.

What is the Mobile Internet?

Mobile Internet refers to access to the internet using a cellular phone or other wireless device. Often times, internet by cell phone is downsized to accommodate a cell phone’s web browser. Similarly, mobile web refers to a downsized version of a website that can accommodate a cell phone’s web browser. iPhone’s 3G model offers free downloads of Safari, enabling users mobile internet access and has touchscreen functionality so that pages can be enlarged to make reading text easier.
Technology, though, is rapidly opening up mobile internet technology. Opera Mobile is a browser on the Windows mobile operating system that enables cell phones to view full websites on the Internet.

Mobile Internet Technology

Mobile Internet uses the 1900 megahertz digital radio frequency band, known as PCS (Personal Communications Service). The growing demand for mobile internet access has been a main driver of cell phone technology and innovation over the device’s generations.

The Generations of Mobile Internet Phones

The road to mobile internet service actually began back in the 1940s at Bell Labs with the development of hexagonal cells that provided the underlying technology of the wireless business cell phone, where frequencies are repurposed in a regular pattern of areas, called cells. In wireless phone networks these cells are typically hexagonal in shape. The term “cell phones” sprung from this technology.
Bell Labs also developed the idea of cell towers capable of transmitting and receiving signals from three directions, as opposed to antennae technology, which is bi-directional.

Mobile Internet Phones

1G

The first functional wireless phones were referred to as First Generation, or 1G, analog phones, modulated to frequencies 150MHz and up. Static-filled and plagued by interference, the sound quality of the connections was hardly better than on the first phones Alexander Graham Bell used.
The first wireless phones were only used as mobile phones permanently attached to the car’s floor board. Within a few years, they were available as portable phones. Marketed by Motorola, these 1G phones were bulky, the carrying case the size of a small carry-on bag. These models were very expensive so were mostly used by executives, status-seekers or early adopters seeking bragging rights.
Beside quality of service issues and cost, 1G phones faced some social hurdles as well, such as consumers’ discomfort with the idea that their private conversations might be overheard if conducted in public.

2G

The 2G networks were launched commercially in Europe on the GSM (Global System for Mobile) standard in 1991. 2G networks improved on 1G wireless technology in three key areas. First, they converted the voice data to digital signals. Second, they enabled broader wireless penetration because of their spectrum efficiency, meaning they transmitted data faster over their bandwidth. Lastly, 2G technology enabled data services, such as SMS text messages.

2.5G

2G wireless networks upgraded by the inclusion of General Packet Radio Service (GPRS) are known as 2.5G. These networks GPRS is a packet switching technology. It works by breaking data up into small pieces called packets. Each packet includes a header, which specifies where the data came from and where it’s going. The chunk of data is routed independently via the least congested path. Once the packets all arrive at the intended destination, they are pieced back together. Packet switching increases network efficiency. It also enables always-on capability, which is an important aspect of mobile Internet service.

3G

3G is the informal name for International Mobile Telecommunications-2000 (IMT-2000), a group of related cellular standards which includes GSM EDGE and WiMAX. 3G services include wireless voice, video and data on the mobile platform. 3G enables simultaneous use of voice and data services and faster transmission rates through more efficient spectrum use. 3G supports multimedia applications such as video conferencing and mobile TV.
3G’s increased data speeds and network efficiency ushered in the explosion of mobile internet services with downlink rates up to 14.0 Megabits per second and uplink rates of 5.8 Megabits per second.

4G

4G is the next generation mobile network being developed to handle a suite of advanced digital services including MMS, HD content, video chat and digital television in addition to voice and data, all over an IP, packet-switching network. Among the objectives of 4G are data rates of 100 Megabits per second. The most anticipated 4G technology is WiMAX, which revolutionize cell phone’s mobile internet capabilities.

WiMAX Mobile Internet Services

In the future of mobile internet services, WiMAx is the future! Sometimes referred to as business WiFi on steroids, WiMAX is a wireless digital communications system, also known as IEEE 802.16. WiMAX can provide broadband wireless access (BWA) up to 10 miles for mobile stations. By comparison, WiFi (the 802.11 wireless local area network standard) is typically limited to around 300 feet. In other words, it can accommodate higher data rates over longer distances An open system, WiMAX is the only network optimized specifically for broadband mobile Internet. This technology, along with voice over ip, could be the future of telecommunications.

WiMAX is a 4G technology that provides high-speed broadband service over expanded coverage areas and at lower costs. WiMAX is expected to drive development of many next generation devices such as cell phone, Mobile Internet Devices (MIDs) and assorted consumer electronic devices.
Using an all-IP network architecture and offering compatibility with existing 2G and 3G cellular network deployments, WiMAX is positioning itself as the cost efficient option for mobile internet solutions. As a result, it has been endorsed by device manufacturers and wired and wireless operators alike, since WiMAX technology works for both platforms.

What is CLEAR 4G WiMAX?

CLEAR 4G WiMax is a new mobile interest service from Clearwire that is 4 times faster than a typical 3G network, with reported download speeds of 4 megabits per second and upload speeds of 500 kilobits per second. It’s the fiber ring of wireless!

Mobile Internet Standards

Even though GSM originated in Finland, it was adopted worldwide and is currently used by an estimated 80 percent of wireless phone user on earth.
   TDMA (Time Division Multiple Access) and CDMA (Code Division Multiple Access) are standards that optimize radio spectrum use by allowing multiple users to share the same physical channel. In other words, the standards prevent interference when more than one conversation is being transmitted on the same frequency.
   The only difference between TDMA and CDMA is the way they allow the frequency to be shared. TDMA divides the channel into sequential time sections. Each called gets to use one of the slices for a brief period before it is passed along to the next caller. All of this happens in fractions of a second. So even if there are multiple called on the same channel, in reality only one at a time is able to use it.
   The CDMA standard uses digital technology called Spread Spectrum to enable actual simultaneous transmissions by taking a caller’s signals and spreads them randomly across a very wide channel. The receiver’s device then reassembles the scattered bits of data.
TDMA has been incorporated into the GSM standard and is used on 2G phones. CDMA is the standard used by most major 3G phone manufacturers.
