4G refers to the 4th Generation of mobile technology. First generation (1G) was the analogue standard deployed by mobile networks launched in the early 1980's - Nordic Mobile Telephone (NMT) in Europe and Advanced Mobile Phone System (AMPS) in the US.
Second generation (2G) was the digital standard utilised by mobile networks launched in the early 1990's (GSM around the world, TDMA/CDMA in the US).
Third generation (3G) was launched in the early 2000's with WCDMA and EVDO as the main standards.
4G is the fourth generation, and was first deployed in networks around 2008-2009.. 4G today mainly refers to Long Term Evolution (LTE), Worldwide Interoperability for Microwave Access (WiMax) or (High Speed Packet Access (HSPA+)
No. You will need to subscribe to one of our mobile data plans. LIME offers a variety of data plans for BlackBerry, smart phone of on-the-go data devices (such as dongles/USB modems).
The new network uses the latest technology and does not in itself affect battery life .. Battery life in your device will depend mostly on usage and screen size
You should note though that if you are making many calls, using multiple applications that use the device’s CPU heavily (example some screen savers or games,), or using the Internet a lot, battery life may be reduced.
Battery life can be increased by closing or limiting the number of active applications, and by turning off Wifi, and Bluetooth when not in use.
We offer up to nine devices that are perfect for mobile data and are 4G compatible. These include BlackBerry Bold 9900, BlackBerry 9860, the Apple IPhone 4S the Huawei Mi-fi E586.
However, LIME is committed to offering a range of new high performing 4G devices including USB modems, mobile phones, tablets and MiFi devices at launch. As more devices become 4G devices become available LIME will make every effort to ensure that its customers have access to purchase these devices as they become available.
In any case, don’t forget you don’t need to get a device as fast as 21Mbps to enjoy an amazing experience. Already, 3.6 Mbps will give you the feeling of your broadband at home and 7.2 Mbps will give you a faster speed than many people enjoy in their homes today.
In the far right hand corner of your screen your device will display “3G” or “HSPA” or “HSDPA” or in some instances it may simply show an “H”. The icon displayed varies according to the handset or device make and/or model.
LIME has a plan to launch 4G across the Caribbean. Our customers in Cayman and Barbados will be the first to enjoy 4G in 2011! Our plan, is that you will be enjoying the fastest network you can imagine on a mobile device before this Christmas! If anything changes, we will let you know.
Security on 2G (GPRS and EDGE) and 3G networks are all extremely secure and the 4G HSPA+ networks, offer the same level of security mechanisms and are complemented by upgraded security features.
Customers should always be cautious when sharing information electronically and should take all necessary precautions to safeguard their personal sensitive informative information.
No. Existing customers will be able to enjoy the new 4G network speeds as long as they have a mobile Internet data plan or BlackBerry data plan and compatible mobile phone or BlackBerry device. Customers may also upgrade their mobile data plans as their data usage patterns change.
With a network dimensioned for 21 Mbps, typical user speeds will be between 4-15 Mbps at peak periods. Of course, the speed achieved will depend on traffic load, coverage and even more importantly, the mobile device used. Currently there are only a few devices capable of such speeds but LIME will carry 4G devices in its handset range as these devices become available. Like many international carriers, LIME presently stocks an array of smart phones and data capable devices which are capable of download speeds of up to 3.6 or 7.2. These devices will perform exceptionally well on the new 4G network.
In simple terms what this means is that with a compatible smart phone or USB Modem (PC/dongle), you could potentially download a high definition video within in a matter of seconds - twice the speed at which you download it now on a 2G or 3G network.
Though the sector has the capability of delivering a maximum download speed of 21 megabytes per second customers will not realize that optimum speed because there will be other users sharing the sector and everyone is accessing different types and size of data at varying times. As such the speed on the sector is shared among those users.
For example if there is a significant number of users accessing data within a specific location you may not experience a download speed of 21 Mbps, but your user experience is still going to be superior to what you would have on EDGE or 2G.
