Average UK mobile broadband speeds range between 1.5 Mbps and 2Mbps. Top speeds could reach 6Mbps in areas where the users could get strong data signals.

However, operators advertise the maximum speeds which can be misleading unless the customers are well informed over the issues like 3G coverage that could potentially reduce the speeds or even disconnect the service at the worst.

Now, to help the consumers to make informed decisions on buying mobile broadband, the advertising regulators Committee of Advertising Practice (CAP) and the Advertising Standards Authority (ASA) have introduced new advertising guidelines under which the advert speeds should atleast be achievable by 10% of the customers.

The rule which applies to fixed line service, will now have impact on unrealistic speed claims by mobile operators and will be implemented from November 2012, it has been revealed.

Current HSPA technology that mobile networks use is capable of delivering up to 7.2Mbps while major providers Three, Vodafone and O2 already making investments on upgrading their networks to faster, 21Mbps capable, HSPA+ technology.

This means, the new guidance will make providers to reduce the current maximum speeds they claim in the adverts after three months.
