Mobile application development business moves quickly. The Internet presents a consistent challenge, every 48 hours the amount of data consistent with all information produce up through 2003 is reproduced (Siegler, 2010). Simultaneously, the Internet is not an automatically cumulatively consistent archival system. During the evolution, the Internet’s backbone changed several times (Picon, 2010).
Contrary to belief, the Internet is not constituted by a core of servers linked one to another by CISCO routers, but rather by the multitude of connected users keenly proporting their user experience as good or bad.
With the addition of HTML 5’s implementation and the significant shift from desktop to the mobile platforms, the Internet challenged how business is done. The framework of how business work online must consider the new platforms. To be clear, your website doesn’t work the same on a phone as it would your desktop. In 2014, More users will surf the Internet using their mobile devices than standard desktop platforms (Minato, 2012)
With that shift in mind, doing business now must consider mobile devices user experience. Every company working online must consider element of their mobile business platform. Here are 5 things you need to know about Global System for Mobile communication (GSM) and C ode D ivision M ultiple A ccess ( CDMA) for business mobility from this day and beyond. Here I will identify what the two are and how it impacts businesses. Also, I will demonstrate how businesses can take advantage of today and in the future.
GSM vs. CDMA: What is GSM?
What is GSM? GSM stands for Global System for Mobile communications. What GSM actually does is allow for an open, digital cellular technology to be used for transmitting mobile voice and data services. GSM supports voice calls along with data transfer speeds reaching 9.6 kbps, along with the transmission of SMS (Short Message Service).
GSM operates in the 900MHz and 1.8GHz bands in Europe and the 1.9GHz and 850MHz bands in the US. Most GSM phones will and can work overseas for a fee because the system is a European standard. GSM phone key trigger is the SIM ( Subscriber Information Module) card which is the linchpin for all GSM phones. GSM services are also transmitted via 850MHz spectrum in Australia, Canada and many Latin American countries. The use of spectrum harmonization globally, combined with GSM’s international roaming capability, allows travelers to access the same mobile services at home and abroad for a fee. GSM enables individuals to be reached via the same mobile number in and up to 219 countries allowing mobile phone usage to cross country borders.
GSM networks now cover more than 90% of the world’s population. GSM satellite roaming has also extended service access to areas where terrestrial coverage is not available. With a Dual-band phone your phone can cover multiple frequency bands allowing your phone coverage to continue moving through regions with different bands .
GSM vs. CDMA: What is CDMA?
What is CDMA? CDMA stands for Code Division Multiple Access. What it does is focus on the cell phone provider to have a white list of approved users. In short, there is no SIM card. CDMA uses a “spread-spectrum” technique whereby electromagnetic energy is spread to allow for a signal with a wider bandwidth. This allows multiple people on multiple cell phones to be “multiplexed” over the same channel to share a bandwidth of frequencies.
With CDMA technology, data and voice packets are separated using codes and then transmitted using a wide frequency range. Since more space is often allocated for data with CDMA, this standard became attractive for 3G high-speed mobile Internet use.
The CDMA standard was originally designed by Qualcomm in the U.S. and is primarily used in America and Asia by certain international carriers. In America the major carriers are:
1) Sprint ,
2) Virgin Mobile and
3) Verizon Wireless
GSM carriers are:
1) T-Mobile and
While CDMA and GSM compete head on in terms of higher bandwidth speed (i.e. for surfing the mobile Web), GSM has more complete global coverage due to roaming and international roaming contracts.
GSM technology tends to cover rural areas in the U.S. more completely than CDMA. Over time, CDMA won out over less advanced TDMA technology, which was incorporated into more advanced GSM.
GSM vs. CDMA: Why Its Crucial to Mobile Businesses?
As a developer, user experience (UX) is everything. Great UX can result in your brand having rave reviews when you are “Googled”. Poor UX can result in your business sales, lead pages or products being buried under a mountain of customer complaint on every social media channel at once. Your brilliant great new message will not come through as a result of all the noise against your company’s brand.
So, why is GSM vs CDMA crucial to your mobile business. First off, if you have a mobile website you need to know exactly how your site performs on a device. But not just the device, you need to know how your website performs on the devices network. An iPhone 4S will not perform the exact same way on a Verizon network as it will on a AT & T network. You need to really be aware of the regional capability of your customer base and build your application to best meet that need. With consideration that if the site takes too long to load, or a application fails because of signal, you can have a wonderful application that results in horrible UX and thereby deteriorates your sales opportunities.
So for any website and application, you must have a UX testing and auditing approach that give your users the best possible UX.
GSM vs. CDMA: What you can do for your mobile business?
Business mobility is more than having a mobile website. Today, business owners must understand their avatar & how user experience is impacted on by framework architecture design.
