We use technology based on the 3GPP family of standards. Currently our mobile networks consist of GSM/GPRS, EDGE/HSDPA and HSPA+/LTE technology. The 3GPP family of standards are the most broadly-deployed worldwide, and allow for our customers to use their mobile devices on networks around the world. The standard determines how the digital wireless signal is transmitted between the mobile device and the cell tower and also manages the limited amount of frequency available in a given location.
4G networks give you higher data speeds even compared to 3G. Not only will you experience greater coverage on 4G but you will also get faster Internet connection, an improved browsing experience, shorter download times and faster access to applications. Simply put 4G enhances the mobile lifestyle and experience.
Long Term Evolution (LTE) is the next step in the mobile network technology evolution from WCDMA/HSPA. While HSPA+ builds on radio and core network technologies from GSM and UMTS (Wideband CDMA), LTE completely transforms the mobile radio network design. It will provide even higher bandwidth, lower latency, and greater mobility than HSPA+, and in the future shared sector bandwidth of well over 100 Mbs thereby allowing customers to realize even greater speeds.
With LTE, customers will enjoy playing games online, downloading and watching High Definition videos or movies even more, and with MiFi hotstops for multiple devices and tablets they will have greater mobility.
Yes. LIME's new 4G network has been designed to be easily extendable to support LTE and in the very near future LIME will be rolling out 42 Mbps HSPA+ in some of its countries of operation.
Yes. If roaming within the Caribbean in any of the LIME countries where 4G HSPA+ has been enabled, or if your are visiting any of the international countries where LIME has a roaming agreement and where that network operator who has HSPA+ enabled. As always you should check that your mobile device supports the mobile frequencies which are used by the mobile operator in the country where you are roaming. For further information on roaming you may log on to www.lime.com.
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.
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.
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.
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.
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.
No. You will be able to use the latest BlackBerry devices, including the 9800, 9780, 9300 and 8520, on the new network. BlackBerry and other data phone users will immediately notice the very speeds which our new 4G network offer.
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.
